Thermodynamics of solvent-driven water extraction from hypersaline brines using dimethyl ether

Solvent-driven water extraction (SDWE) has promising applications in hypersaline brine desalination, including zero-liquid discharge processing for industrial wastewaters, and resource recovery, such as the extraction of lithium and rare earth elements from solution mining leachates. In this study, we develop a computational thermodynamic framework to analyze the liquid–liquid extraction of water from hypersaline brines using dimethyl ether (DME), an aprotic solvent that is partially miscible with water. The high volatility of DME enables its rapid separation from water–DME mixtures after water absorption, while its low polarity minimizes the organic-phase solubility of electrolytes, such as sodium chloride (NaCl). We first build a thermodynamic model based on the LIQUAC excess Gibbs free energy model for water–DME–NaCl mixtures. Maximum likelihood estimators for water–DME–NaCl interaction parameters are calculated through the nonlinear regression of fluid phase equilibrium and osmotic coefficient data using metaheuristic global optimization techniques. A multistage counter-current liquid–liquid separator (LLS) model is then developed to explore the water recovery and brine concentration ratios achievable as a function of feed molality and DME to feed water flow rate ratio. For a saline feed with a molality of 2.0molkg−1 (over three times the salinity of seawater) our analysis demonstrates that a one-stage LLS can achieve a water recovery ratio of 0.51 with an initial DME to saline feed molar flow rate ratio of 4.0, rising to 0.63 with a second equilibrium stage. We conclude by quantifying the amount of DME required to reach zero-liquid discharge brine salinities and analyzing the impact of staging and temperature on separation performance. Our thermodynamic model enables the rapid evaluation of SDWE systems for emerging hypersaline brine desalination and valorization applications.

Pervaporation recovery of valuable aromas from by-products of the seafood industry: Modelling of fractionated condensation for off-flavour removal

Following a circular economy approach, an integrated process is proposed for aroma recovery and fractionation from seafood industry aqueous effluents, combining the advantages of organophilic pervaporation and fractionated condensation.The aim of this work is to recover valuable aromas from aqueous effluents of seafood processing assuring that the aromas recovered are, as much as possible, free from off-flavours in order to be applied as seafood flavouring additives. To reach this objective, an integrated organophilic pervaporation/fractionated condensation process was assessed, with the support of a mathematical model.The mathematical model described and validated in this work allows for simulating the integrated pervaporation - fractionated condensation process and select the optimal operating conditions for a given target separation, performing a minimum experimental work (that comprise only pervaporation with total condensation experiments and inert gas molar flow rate measurements) and using reliable thermodynamic properties (saturation vapour pressures and activity coefficients).The application of this model proves to be a very useful tool for predicting the fractionation of aromas of different chemical families. Which allows to anticipate its wider application, beyond the seafood aroma case-study discussed in this work.

SIMULATION OF CRYOGENIC DISTILLATION OF ATMOSPHERIC AIR USING ASPEN HYSYS

Nitrogen has significant commercial and scientific importance in both its gaseous and liquid states. The atmosphere is a rich source of the same, and it can be used as a raw material to obtain it. However, the technology and the possibility of implementing specific procedures and machinery appear to be difficult. In this scenario, cryogenic distillation is used to separate nitrogen from atmospheric air in its purest form. Aspen HYSYS is used for steady-state and dynamic simulation of the process. The goal of the simulation is to find the best process parameters and thus the purest form of nitrogen. Simulation studies of steady and dynamic states are carried out. Product purity, molar flowrate, product recovery, specific power, and various behaviors depending on control setup will be researched.

Hydrogenation of CO/CO2 mixtures under unsteady-state conditions: Effect of the carbon oxides on the dynamic methanation process

The Power-to-Gas (PtG) process offers the opportunity to store fluctuating renewable energy in form of chemical energy by hydrogenating carbon oxides into methane. In addition, potential carbon point sources often consist of CO/CO2 (COx) mixtures. Hence, reactor design requires kinetic models valid for unsteady-state operation and a broad spectrum of feed gas compositions. In order to provide the required experimental data basis for derivation of kinetic expressions valid under transient conditions, the dynamic response of a continuously operated fixed-bed methanation reactor is studied by applying periodic step-changes in the feed composition. The obtained results are evaluated based on a simple reactor model, providing the molar flow rate exchanged between the gas bulk and the solid surface for CO, CO2, CH4, and H2O. The results further reveal that the transient kinetic processes at the catalyst surface strongly affect the reactor response under reaction conditions of technical relevance.

Multi-Objective Optimization of Braun-Type Exothermic Reactor for Ammonia Synthesis.

The exothermic reactor for ammonia synthesis is a primary device determining the performance of the energy storage system. The Braun-type ammonia synthesis reactor is used as the exothermic reactor to improve the heat release rate. Due to the entirely different usage scenarios and design objectives, its parameters need to be redesigned and optimized. Based on finite-time thermodynamics, a one-dimensional model is established to analyze the effects of inlet gas molar flow rate, hydrogen–nitrogen ratio, reactor length and inlet temperature on the total entropy generation rate and the total exothermic rate of the reactor. It’s found that the total exothermic rate mainly depends on the inlet molar flow rate. Furthermore, considering the minimum total entropy generation rate and maximum total exothermic rate, the NSGA-II algorithm is applied to optimize seven reactor parameters including the inlet molar flow rate, lengths and temperatures of the three reactors. Lastly, the optimized reactor is obtained from the Pareto front using three fuzzy decision methods and deviation index. Compared with the reference reactor, the total exothermic rate of the optimized reactor is improved by 12.6% while the total entropy generation rate is reduced by 3.4%. The results in this paper can provide some guidance for the optimal design and application of exothermic reactors in practical engineering.

Multi-objective optimal configurations of a membrane reactor for steam methane reforming

The combination of traditional reactor and permeable membrane is beneficial to increase the production rate of the target product. How to design a high efficiency and energy saving membrane reactor is one of the key problems to be solved urgently. This paper utilizes finite-time thermodynamics and nonlinear programming to solve the optimal configurations of the membrane reactor of steam methane reforming (MR-SMR) for two optimization objectives, that is, heat exchange rate minimization and power consumption minimization. The exterior wall temperature and fixed hydrogen production rate are regarded as the control variable and constraint, respectively. The results indicate that the hydrogen production rate and heat exchange rate in MR-SMR are increased by 108.58% and 58.42%, respectively, while the power consumption is reduced by 33.44% compared with those in the traditional reactor under the same condition. Compared with the results in reference reactor (MR-SMR obtained with initial values), the heat exchange rate is reduced by 1.40% by optimizing the exterior wall temperature, and the power consumption is reduced by 5.10% by optimizing the exterior wall temperature and molar flow rate of sweep gas. The optimal distributions of exterior wall temperatures in the optimal reactors of minimum heat exchange rate and power consumption have a theoretical guiding significance for the thermal design of the membrane reactors.

A novel hybrid process for production of cyclohexanone oxime and high temperature hydrogen production using solar energy

In the presented study, an integrated novel process for cyclohexanone oxime and power production by utilizing solar dish collectors and high temperature hydrogen production systems (water decay) is studied. This process is comprised from solar dish collectors, Cu-Cl thermochemical cycle, direct H2O2 production cycle, cyclohexanone oxime and organic Rankine cycle. In the thermochemical process, 2208 kg/h of oxygen and 278.5 kg/h of hydrogen are generated that 139.4 kg/h of hydrogen is the net generated hydrogen. Moreover, this system generates 9429.8 kW of power that 2419 kW of power is employed in Cu-Cl cycle, 808.8 kW is consumed in hydrogen peroxide production cycle and the rest, which is 6202 kW is the net produced power. This process for 6305.9 kg/h cyclohexanone produces 8504.3 kg/h cyclohexanone oxime. The cyclohexanone ammoximation also generates 1238 kW heat. Furthermore, a sensitivity analysis is performed to investigate the effect of some performance parameters on various design indicators. It can be comprehended that the increment of operating wall temperature leads to decrement of solar collector energy efficiency. On the other hand, increment of geometric concentration ratio results in higher collector thermal efficiency. By using more solar dishes, the generated cyclohexanone oxime, hydrogen and hydrogen peroxide molar flow rates rises 40.5%. 43.5% and 37.8%, respectively. Moreover, the organic Rankine cycle and total system’s efficiency increases 38.1% and 43.3%, respectively by increase in number of solar dishes.

Thermal Self-Sufficient Operation of Hydrogen Production from Used Vegetable Oil

This work aims to investigate the hydrogen production from used palm oil and used soybean oil through autothermal reforming (ATR). Thermodynamics analysis of this process was performed by using Aspen plus V9 simulation software. The gas compositions at equilibrium were calculated by using the Gibbs free energy minimization method. The hydrogen production process was composed of ATR reactor, high-temperature water gas shift (HT-WGS), low-temperature water gas shift (LT-WGS) and absorber. Considering the optimal conditions of each unit operation, it was found that the maximum hydrogen production can be provided when ATR reactor was operated at temperature of 580 °C, atmospheric pressure, steam to carbon (S/C) molar ratio of 10 and oxygen to carbon (O/C) molar ratio of 0.1. HT-WGS and LT-WGS reactors should be operated at temperature of 300 °C and 200 °C. For the absorber, the optimal conditions were at 40 atm with 6 kmol/h of MDEA solution at 35 °C. Under these operating conditions, hydrogen can be generated as 2.56 kmol/h or 99.7 mol%. Then, the hydrogen production under thermal self-sufficient operation was studied. The simulation result indicated that the ATR reactor should be operated at temperature of 580 °C and atmospheric pressure with S/C molar ratio of 4.5 and O/C molar ratio of 0.47 to achieve thermal self-sufficient operation. When the ATR reactor was operated under these operating conditions whereas the operating conditions of HT-WGS, LT-WGS and absorber were constant, it was found that hydrogen with molar flow rate of 1.71 kmol/h (99.7 mol%) can be provided.

An innovative hybrid structure of solar PV-driven air separation unit, molten carbonate fuel cell, and absorption–compression refrigeration system (Process development and exergy analysis)

The regasification of liquefied natural gas provides considerable cold energy that would have practical potential in different industrial fields and makes a suitable option for integrating with cryogenic air separation systems that requires a significant amount of energy. In this research, two-column cryogenic air separation units are driven with solar photovoltaic panels to produce oxygen and nitrogen. The gaseous natural gas feeds a molten carbonate fuel cell (MCFC), producing electricity and heat. The heat is recovered by an absorption–compression refrigeration cycle (ACRC) to supply a high-intensity cooling load at −67 °C. The proposed scheme is designed to provide 1781 kmol/h oxygen, 8574 kmol/h nitrogen, 136 MW electrical power, and 13.09 MW cooling load. The thermal efficiency of the whole combined structure and the electrical efficiency of the fuel cell are 51.07% and 51.93%, respectively. The exergy analysis illustrates that the solar photovoltaic collectors and heat exchanges are the two most exergy destructive components compared to others. The exergy efficiency and irreversibility of the developed hybrid process are 52.77% and 160.5 MW, respectively. The effect of working temperatures has been studied on the performance of the molten carbonate fuel cell, including voltage, power density, and efficiency. The exergy and thermal efficiencies of the proposed system increase up to 56.18% and 55.05%, respectively with an increase of LNG molar flow rate from 892 to 992 kmol/h.

Metalorganic chemical vapor deposition of α-Ga2O3 and α-(AlxGa1−x)2O3 thin films on m-plane sapphire substrates

Single α-phase (AlxGa1−x)2O3 thin films are grown on m-plane sapphire (α-Al2O3) substrates via metalorganic chemical vapor deposition. By systematically tuning the growth parameters including the precursor molar flow rates, chamber pressure, and growth temperature, the epitaxial growth of high-quality phase pure α-(AlxGa1−x)2O3 films (0 ≤ x ≤ 1) is demonstrated with smooth surface morphologies and alloy homogeneities by comprehensive material characterization. The asymmetrical reciprocal space mapping reveals fully relaxed films for α-(AlxGa1−x)2O3 films with x ≤ 0.5. The coherent growth of α-(AlxGa1−x)2O3/α-Al2O3 superlattice structures is demonstrated with abrupt interfaces and uniform Al distribution for higher Al compositions at x = 0.78 in the α-(AlxGa1−x)2O3 layer. The influence of growth parameters, such as growth temperature and chamber pressure, on the phase stabilization and Al incorporation in the α-(AlxGa1−x)2O3 films is investigated. While lower growth temperatures facilitate the phase stabilization of α-Ga2O3 thin films, lower chamber pressure leads to higher Al incorporation in α-(AlxGa1−x)2O3 films. High resolution x-ray photoelectron spectroscopy was utilized for determining the Al compositions and bandgaps of α-(AlxGa1−x)2O3. Furthermore, the evolution of the valance and conduction band offsets at α-Al2O3/α-(AlxGa1−x)2O3 heterojunctions is evaluated with the variation of Al compositions, which reveals the formation of type-I (straddling) band alignment between α-Al2O3 and α-(AlxGa1−x)2O3.

Continuous Flow Friedel–Crafts Alkylation Catalyzed by Silica Supported Phosphotungstic Acid: An Environmentally Benign Process

AbstractSix silica-supported phosphotungstic acid catalysts (PTA/SiO2) of different composition (20–70 wt% PTA content) have been synthesized and characterized by elemental analysis, BET, BJH, NH3-TPD methods, FT-IR spectroscopy of adsorbed pyridine and 1H MAS NMR techniques. The new composite catalysts were first applied in the Friedel–Crafts alkylation of toluene with 1-octene as a benchmark process under batch conditions in order to screen their activity and recyclability. The combined analytical techniques together with the catalytic studies enabled the identification of the main factors affecting the activity of the catalysts. Based on these preliminary experiments, the best performing catalyst system (50 wt% PTA/SiO2) was investigated in continuous flow mode using an in-house-made flow reactor. The thorough screening of the reaction conditions (temperature, toluene/1-octene molar ratio and flow rate) provided firm evidence that the 50 wt% PTA/SiO2 composite is highly active, selective and stable catalyst under mild reaction conditions even at elevated flow rate. Additionally, the catalyst used in the flow mode could successfully be regenerated and reused in the alkylation process.

Application of Zn-ferrite towards thermochemical utilization of carbon dioxide: A thermodynamic investigation

This study reports a thermodynamic analysis of ZnFe2O4 based CO2 splitting cycle. The model developed is evaluated by using HSC Chemistry software. Effects of the influence of the ratio of the molar flow rate of inert sweep gas to the molar flow rate of ZnFe2O4, thermal reduction temperature, and gas-to-gas heat recovery effectiveness on thermal energy required to drive the cycle and the solar-to-fuel energy conversion efficiency are investigated at reduction nonstoichiometry of 0.1. The decrease in the reduction temperature is significant when the ratio of the molar flow rate of inert sweep gas to the molar flow rate of ZnFe2O4 increases from 10 to 30. At a steady gas-to-gas heat recovery effectiveness equal to 0.7, a rise in the ratio of the molar flow rate of inert sweep gas to the molar flow rate of ZnFe2O4 from 10 to 90 is responsible for an increase in the thermal energy required to drive the cycle above 184.9 kW by a factor of 1.45 and decrease in the solar-to-fuel energy conversion efficiency by 4%. At gas-to-gas heat recovery effectiveness equal to 0, the difference between the thermal energy required to drive the cycle at the ratio of the molar flow rate of inert sweep gas to the molar flow rate of ZnFe2O4 equal to 10 and 100 is 346.5 kW. However, as the gas-to-gas heat recovery effectiveness increases to 0.9, this difference decreases to 11.8 kW. Because of this, the reduction in the solar-to-fuel energy conversion efficiency also drops to 0.6%. Therefore, a maximum possible solar-to-fuel energy conversion efficiency equal to 16.8% can be achieved.

Effect of Flow Rate Scaling on SAE-InAs Crystal Phase and Integration of Self-Catalyzed InAs/InSb Heterostructure Nanowires on Si (111) Substrate by MOCVD

The effect of III-V molar flow scaling on crystal quality of selectively grown InAs nanowires on patterned Si (111) substrate is investigated by metal organic chemical vapor deposition. We found the correlations between molar flow rate scaling and selectivity and InAs crystal structure have been investigated. When the molar flow rate is higher, nanowire follows random nucleation and exhibits zincblende crystal structure, whereas growth selectivity increases to 97% at intermediate molar flow rates and nanowire exhibits wurtzite dominant crystal phase with occasional stacking faults. Once the molar flow rate is scaled-down aggressively, nanowire exhibits polytype crystal structure with small degradation in selectivity. The resistivity calculated from current-voltage curve of moderate molar flow rate InAs nanowires showed 15.9 × 10–3 Ωcm, which was significantly (1.6 times) lower than typical InAs nanowires with low molar flow rate (25.31 × 10–3 Ωcm). Finally, we integrate axial InSb heterostructure nanowire with two different crystal structures on InAs stem by self-catalyzed selective area epitaxy for the V/III ratio of 2. This study further offers good opportunity to tune the crystal structure of InSb with the help of In-catalyzed growth technique.

Effect of Tin Oxide Coatings by Spray Pyrolysis Process on Mechanical Properties of Aluminium, Brass and Mild Steel

Mechanical properties of materials are enhanced by different methods to increase the usage of the materials. In this research spray pyrolysis method is employed to increase the mechanical characteristics of three different materials. The tin oxide is chosen as coated material and aluminium, brass, mild steel are selected as substrate materials. The 500nm thin film is developed over the substrate materials by spray pyrolysis. The substrate temperature are chosen as 300? C for aluminium, 400? C for brass and mildsteel. Nozzle to substrate distance is 0.4 m, substrate temperature is 300? C for aluminium and 400? C for solution concentration as 0.2 mole and solution flow rate is 1ml/min are selected for constant deposition parameters. The hardness and tensile strength result clearly shows that strength is increased by adding the coating over the surface. The material is heated above crystallization temperature and SnO2 increases the tensile and hardness strength of the materials. The triangular metrological microscope is used to examine the microstructure of non coated and coated substrate materials. The microstructural analysis is showed that the uncoated surface of the substrate material is full of rough and pores. And displays that the tin oxide coated surface of the substrates after the initial deposition disclosed a surface with a agglomeration of tin oxide in homogeneous and uniform than the uncoated substrates.

Optimization of post combustion CO2 absorption system monoethanolamine (MEA) based for 320 MW coal-fired power plant application – Exergy and exergoenvironmental analysis

Carbon Capture and Storage (CCS) technology which has been widely used, such as CO2 absorption system, still has environmental and energy issues. Further investigations should be carried out by understanding the causes of inefficiency in the system. Exergy and exergoenvironmental analysis are the method to describe the associated of each component in the system so that it can be optimized to produce optimum operating condition. A comprehensive study of coal fired power plant using CO2 absorption with MEA (monoethanolamine) solution is presented. This paper aims to optimize the CO2 absorption system by maximizing exergy and minimizing exergoenvironmental. Exhaust gas temperature, MEA molar flow rate, and reboiler duty on the regenerator are chosen as the decision variables. The results showed that, the optimum operating conditions of the three variables respectively are 90 °C, 2,500 kmol/h, and 9.14 MW. From the exergy and exergoenvironmental calculation results, the components which should be improved are heat exchangers, regenerators, and absorbers since they have minimum exergetic efficiency and have many byproducts given to the environment. This study can be the basis for maximizing the efficiency of the CO2 absorption system which has implications for reducing environmental impacts through optimization of components in the CCS system.

Kinetic study and Modeling of heavy Naphtha Catalytic Reforming process in AL-Daura Refinery

In the present work, kinetics and modeling of heavy naphtha catalytic reforming process in Al-Daura refinery-Midland refineries Company were studied. A proposed reaction scheme involving (15 pseudo components) connected together by a network of 30 reactions for components in the C6-C8+ range have been modeled. In the present work, kinetics and modeling of heavy naphtha catalytic reforming process in AL-Daura refinery-Midland refineries Company were studied. A proposed reaction scheme involving (15 pseudo components) connected together by a network of 30 reactions for components in the C6-C8+ range have been modeled. The proposed model has been solved numerically using the 4th order Runge–Kutta approach. Alteration of components and temperature, with time and reactor length was evaluated. Results showed that the rate of formation of aromatics is becoming slower as the reactants proceed to the third reactor. The catalytic reaction rates in the reformer are well represented by the Hougen-Watson Langmur-Hinshelwood (HWLH) type form. The deactivation of catalyst causes the reactor behavior to continue changing over a longer period of time. This clearly seems to pay off in the scenario where coke deposition plays such a major role. It was also found that the rate of coke formation increases with the progress from first to the last bed, so keeping a decreasing inlet temperature profile from first to the last bed would lead to more uniform coke content in each bed. The production rate of reformate has a negative impact on the octane number. Temperature drop across the first reactor (~ 45oC) is larger than the temperature drops across the other two reactors (10-12oC). This could be related to the endothermic reaction rate which is faster in the first reactor. The results show that perfect agreement of temperatures, compositions, and fractions molar flow rate at the exit of the third reactor is obtained between predicted values and industrial values.This confirmed the reliability of the present model.

Effect of an axial-radial plate reactor modifications on a mega methanol plant production

Abstract Axial-radial flow plate reactors have been recently considered as efficient and practical types of reactors for methanol synthesis. Generally, an axial–radial reactor (AR) consists of two main parts namely the axial section and the radial section and the vast majority of the feed enters the radial section. Moreover, the structure of AR has a space above the axial part, which can add an adiabatic bed in the system. In this study, the performance of two novels AR configurations is investigated to improve the effectiveness of the axial–radial plate reactor. In the first configuration, the optimum length of the adiabatic bed is calculated and the adiabatic bed is located above the axial section inside the AR and is named IAAR. Therefore, in IAAR the feed of the axial section just enters the adiabatic bed and warms up. On the other configuration, the adiabatic bed with the optimum length is placed outside the reactor and is named OAAR. Therefore, in OAAR the total feed passes through the adiabatic bed, highly warms up, then cools to the optimum temperature in a heat exchanger, and finally enters AR. Two-dimensional mathematical modeling via orthogonal collocation on the finite element method is developed to compare the performance of two configurations. The results show that the maximum proportion of methanol produces in IAAR, which is approximately 3.8% higher than that produced in conventional AR due to utilizing an adiabatic bed inside the AR and superior gas distribution in the process. Momentum, mass, and heat equations are calculated and molar flow rates, mole fractions and temperatures are depicted along the radius and the length of the three configurations.

A new developed integrated process configuration for production of hydrogen chloride using geothermal and wind energy resources

Ethylene dichloride thermal cracking is one of the conventional methods for hydrogen chloride production. A critical issue concerned with this method is to provide thermal energy for cracking reaction, which is generally provided by the flammable gasses inside the furnace. Utilizing renewable energy sources can be an interesting topic in this case. Hence, in this paper, the thermal integration feasibility of an ethylene dichloride cracking unit with a hybrid renewable plant, based on geothermal and wind energies, is investigated, while the case study for wind turbines system (Alstom ECO 74/1670/ Class II model) is Meshkin Shahr, located in Iran. To utilize geothermal energy, a high-temperature heat pump cycle is developed to transfer heat energy from the heat source (geothermal reservoir) to the system. Moreover, the excess thermal energy produced by the geothermal heat pump cycle is used in an organic Rankine cycle to generate power. The parametric study's results show that the wind turbines and organic Rankine cycle generate 54532 kW and 19107 kW power, respectively. The geothermal plant provides 10490 kW and 103778 kW heat duty required by the cracking unit and organic Rankine cycle, respectively. Moreover, the integrated structure's main product is hydrogen chloride with a molar flow rate of 131.13 kgmole/h and a purity of 81.71%. The results of the economic analysis of the hybrid system illustrate that the period of return and additive value are 2.735 years and 0.0642 US$/kg HCl.

High performance Ni-based porous catalytically activated absorbers and establishment of kinetic model for complex solar methane dry reforming reaction system

High performance Ni-based porous catalytically activated absorbers (PCAA) was prepared and experimentally studied for methane dry reforming reaction. Effects of critical operating parameters were discussed to disclose their influence on variation trends of outlet composition of each species. With experimental results, kinetic models of PCAAs for the complex methane dry reforming reaction were extracted by using plug flow model, nonlinear least squares fitting method as well as genetic algorithm. It was found that (1) High CO2/CH4 ratio is beneficial to increase CH4 conversion and CO/H2 selectivities; (2) High temperature condition would increase conversions of CH4 and CO2, but decrease CO selectivity; (3) The increase of molar flow rate would decrease CH4 conversion & CO/H2 selectivities, and increase CO2 conversion; (4) Compared to other reported models, the established kinetic models can predict the outlet molar fractions of species well, showing great potential for the design and optimization of PCAA-type solar reactor.

Herein, solar dish collector, phase change material energy storage, solid oxide electrolysis cell, and thermoelectric generator sub-systems for synchronous supply of hydrogen and electricity in Farakhi village was introduced for the first time and comprehensively investigated. A hybrid renewable energy system was integrated into the integrated structure to generate and store the direct current electrical energy required by the solid oxide electrolysis cell sub-system and other consumers. Modeling of solar dish collector, phase change material energy storage, and thermoelectric generator sub-systems were performed in MATLAB engineering software, while solid oxide electrolysis cell sub-system modeling was carried out both in ASPEN HYSYS and MATLAB software. In addition, the modeling of hybrid renewable energy system was conducted by HOMER Pro software. It is worth noting that this is the first study presented on the use of hybrid renewable energy system to generate and store electrical energy required by process facilities. The influence of influential parameters on the proficiency of each sub-system was examined comprehensively through sensitivity analysis. The results obtained revealed that the amount of utilizable heat absorbed by the heat transfer fluid as well as the outlet temperature of the collector in summer was considerable than the amount of heat required. Therefore, most of the heat stored in the thermal energy storage sub-system occurred in this season. During charging process of the thermal energy storage sub-system 60.56 kWh of energy was stored. The output power of the thermoelectric generators increased with the molar flow rates of oxygen and hydrogen streams. PV/WT/BG/Bat hybrid system was selected as the best option to supply the required electricity. The share of photovoltaic panels, wind turbines, and biogas generators to supply the required electricity in the first scenario were 53.3%, 35.0%, and 11.6%, respectively. The efficiency of the hybrid system without and considering the thermoelectric generator sub-system was achieved 79.72% and 80.69%, respectively.
