Reforming Natural Gas for CO2 Pre-Combustion Capture in Trinary Cycle Power Plant

Today, most of the world’s electric energy is generated by burning hydrocarbon fuels, which causes significant emissions of harmful substances into the atmosphere by thermal power plants. In world practice, flue gas cleaning systems for removing nitrogen oxides, sulfur, and ash are successfully used at power facilities but reducing carbon dioxide emissions at thermal power plants is still difficult for technical and economic reasons. Thus, the introduction of carbon dioxide capture systems at modern power plants is accompanied by a decrease in net efficiency by 8–12%, which determines the high relevance of developing methods for increasing the energy efficiency of modern environmentally friendly power units. This paper presents the results of the development and study of the process flow charts of binary and trinary combined-cycle gas turbines with minimal emissions of harmful substances into the atmosphere. This research revealed that the net efficiency rate of a binary CCGT with integrated post-combustion technology capture is 39.10%; for a binary CCGT with integrated pre-combustion technology capture it is 40.26%; a trinary CCGT with integrated post-combustion technology capture is 40.35%; and for a trinary combined-cycle gas turbine with integrated pre-combustion technology capture it is 41.62%. The highest efficiency of a trinary CCGT with integrated pre-combustion technology capture is due to a reduction in the energy costs for carbon dioxide capture by 5.67 MW—compared to combined-cycle plants with integrated post-combustion technology capture—as well as an increase in the efficiency of the steam–water circuit of the combined-cycle plant by 3.09% relative to binary cycles.

Chemistry, Analysis, and Biological Aspects of Daprodustat, A New Hypoxia Inducible Factor Prolyl Hydroxylase Inhibitor: A Comprehensive Review.

This review examines therapeutic, pharmacological, and analytical aspects related to the novel drug Daprodustat.

Preliminary study of shear strain-based design approach for onshore wind turbine foundations

Different wind turbine foundation types were analyzed with PLAXIS 3D using a hardening/softening model with a small strain stiffness constitutive model to capture the characteristics of degradation of clays. The study found that even though the conventional design requirements were all satisfied, the shear strains under foundations varied greatly. A literature review regarding the shear strain versus soil degradation was performed, and relevant threshold strains that limit the soils to recoverable behaviors were discussed. A shear strain-based design approach was then proposed and a flowchart for the design process was presented for onshore wind turbine foundations. The proposed design approach simplifies the foundation designs under cyclic loads and relieves the concerns of cyclic degradation and the gapping issue of the foundations subjected to cyclic loads. The analysis results show the shear strains of soils could be effectively controlled within the small-strain threshold by using different structural dimensions, and sometimes together with geotechnical measures. The study found the widely used traditional gravity foundations are governed by conventional design requirements as the shear strains typically are smaller than the threshold level. However, the strain control criterion is dictating deep foundations used for wind turbines.

Time reduction in changing of plastic injection mold part bottom cover injection machine size 380 ton

This study focuses on enhancing efficiency by reducing the time required to adjust plastic injection molds on a 380-ton machine. The setup time for mold change was 61 minutes, exceeding the company's target of 30 minutes. The research employed a quasi-experimental approach, capturing pre-improvement data, measuring the time for each mold change, and documenting sub-work steps using a Flow Process Chart and a Man-Machine Chart. The main activities identified were mold change and Jig robot adjustment using the Quick changeover technique, involving internal and external activities. The study revealed that some mold-changing steps could be prepared in advance, and applying SMED (Single Minute Exchange of Die) and ECRS (Eliminate, Combine, Rearrange, Simplify) principles led to the identification of seven external adjustment steps. Assigning another employee to assist in these steps significantly reduced the average mold adjustment time to 28 minutes, representing a 54.09% improvement.

The article analyzes the current state of development of dimensionally stable tubular elements (TE) and technological problems arising during their production. It is shown that along with empirical methods of studying the influence of various technological schemes on the dimensional stability of tubular elements, it is useful to use the optimal temperature-time mode for heat treatment and, based on it, select the optimal technological scheme. Modeling and determination of the optimal mode of heat treatment of tubular elements were performed. The study of the TE heat treatment mode was carried out in two stages, first by methods of mathematical modeling and optimization, and then by empirical enumeration of various technological schemes. At the first stage, the material properties, which are parameters of the mathematical model, were studied, and the optimal curing modes were calculated. At the second stage, the calculated optimal curing modes were supplemented with various technological methods that cannot be mathematically modeled, and a study was carried out on the influence of the resulting combined heat treatment mode on the geometric characteristics and dimensional stability of carbon fiber TE. The mathematical model of the process of heat treatment and curing of TE in a heat chamber, when heated by a heating air flow, is a system of differential equations: thermal conductivity and curing kinetics. A mathematical model of the process of heat treatment of tubular elements manufactured by the winding method is proposed, the ways of optimizing the curing mode of carbon fiber TE are shown. A numerical calculation of temperature-conversion fields during curing and calculation of optimal curing modes of tubular elements are performed taking into account various process schemes. The values of heat capacity C and thermal conductivity l are calculated depending on the temperature T, the degree of curing b and the filling coefficient g, Безфітингова ферма з вуглепластику Безфітингова ферма з вуглепластику Безфітингова ферма з вуглепластику the power of heat release W and the thermal effect of the curing reaction Q of carbon fiber. Optimum curing modes for a plate made of composite polymer material are obtained, calculated from the data obtained as a result of studying material samples. Temperature-time curing modes are obtained, which are optimized for different thicknesses of the studied material. The statistical hypothesis about the significance of the influence of the process flow chart and reinforcement pattern on the wall thickness of a tubular element and its compressive strength was proved by the dispersion analysis method. The influence of process flow charts and heat treatment modes on the geometric and mechanical characteristics of carbon fiber tubular elements of aircraft truss structures was studied. The statistical hypothesis about the significance of the influence of the process flow chart and reinforcement pattern on the deviation of the wall thickness of tubular elements and their strength characteristics was tested. The significance of the influence of process flow charts with different heat treatment modes on the average wall thickness of a carbon fiber tubular element was statistically proven.

A Novel Plasma-Enhanced Solvolysis as Alternative for Recycling Composites

In this work, a plasma-assisted solvolysis method is proposed as an alternative method for the oxidative degradation of carbon fiber-reinforced composites (CFRCs). Nitrogen plasma ignition within bubbles in a concentrated nitric acid solution is employed, combining the synergistic effects of traditional nitric acid solvolysis and plasma chemistry. A comprehensive process flowchart, including steps such as composite pretreatment, matrix dissolution, fiber recovery and cleaning, solvent regeneration and reuse, and waste treatment, is also discussed, highlighting their importance in process effectiveness. Moreover, a study on the effect of the composite’s mass on the plasma-enhanced solvolysis process is conducted, and the results are exploited for the calculation of critical parameters such as efficiency, recovery rates, capacity, fibers quality, energy consumption, consumption of raw materials, operational and installation costs, and environmental impact. A preliminary comparison to other recycling methods based on the literature findings is also attempted, and preliminary metrics to assess the sustainability of the recycling process are proposed.

Streamlining process development and scale-up: Risk assessment to reduce workload in primary protein recovery

Risk assessment is an integral aspect of the Quality-by-Design strategy to identify potential obstacles at every stage of biopharmaceutical production, from process development to tech transfer. We explored flow process chart, root cause analysis, and failure mode and effects analysis, to assess the scale-up of bacterial cell disruption and its influence on centrifugation and filtration steps. The Ishikawa diagram suggests that data on the impact of homogenizer valve design on product release, impurity profile, particle size distribution, viscosity, and dsDNA fragment size are missing which were collected experimentally for this study. Cell lysates from micro-, lab- and pilot scales cell disruption were analyzed for the above-mentioned parameters. Process parameters affecting these output parameters were identified on each individual scale. Cell disruption on the micro scale was performed in a bead mill. High pressure homogenization was used on lab- and pilot scales. Cell disintegration by bead milling delivers homogenates of product and impurity content comparable to those on bench scale but with 3-fold higher viscosity and significantly larger dsDNA fragments, 8.0 instead of 1.0 kbp, respectively. Miniaturized pressure flow curves identified dsDNA fragment sizes as critical for filter performance during clarification. Combining risk assessment, micro scale cell disintegration and bench scale pressure flow curves allows for selective and efficient process development, and scale up for primary recovery steps.

Optimizing access to care for new patients with cancer discharged from an observation unit.

119 Background: Each year, approximately 33,000 new cancer patients seek treatment at our dedicated cancer hospital, with many placed in our observation unit, the Clinical Decision Unit (CDU). These patients often experience significant delays in receiving oncologic care after discharge resulting in distress for both patients and providers. Our goal is to reduce the two-week appointment time from CDU discharge to outpatient oncologic care by more 10% for those eligible to be seen at the hospital. Methods: In fiscal year 2023, we gathered data on patients admitted to and discharged from the CDU, focusing on new patients. A multidisciplinary team developed a fishbone diagram, process flowcharts, and an impact matrix. Interventions included automated referrals, discharge notifications, patient and provider education, discharge booklets, and oncology recommendations for urgent consults. A physician satisfaction survey was conducted pre- and post-intervention. Three months of post-intervention data (February-May 2024) were reviewed, measuring the baseline percentage of patients receiving an appointment within two weeks, one month or more after CDU discharge. Results: In 2023, 90 eligible patients new to the institution were discharged from the CDU. Of those, 3 (3%) had follow-up appointments within 2 weeks, and 39 (43%) had appointments after 30 days or no appointment at all. Post-intervention data showed that out of 15 new patients discharged between February and May 2024, 10 (66%) had follow up appointments within 2 weeks, 4 (27%) within 30 days, while 1 (7%) had not yet received an appointment. Conclusions: Streamlining the referral process through a central service, automating the requests, and educating both providers and patients can reduce the time to establish oncologic care through an observation unit. However, limitations remain for patients with out-of-network insurance or lack of insurance coverage. Further research is necessary to assess whether expediting follow up cancer care for new patients improves clinical outcomes and relieves associated stress as we suspect it does.

Improving influenza vaccination assessment and uptake, one step at a time in a cancer center.

280 Background: Influenza immunization has shown to decrease morbidity and mortality of influenza infections. From September to December 2022, at the infectious diseases (ID) clinic at our institution, 73% of the patients did not undergo influenza immunization assessment during their clinical encounters and only 3% of the patients had the influenza vaccine administered. Furthermore, documentation of vaccine discussion was done in 73% of cases. Our aim was to improve vaccination assessment from 73% noncompliant to 50%. Methods: A multidisciplinary team of nurses, nurse leaders, pharmacists, and quality specialists was assembled to analyze baseline data on influenza vaccination assessment, administration, and documentation at the ID clinic from Sept to Dec 2022 using The Model for Improvement. Quality tools were utilized including Cause and Effect Diagram, Current State Process Flow Chart and Prioritization Matrix, to identify and prioritize opportunities for improvement creating a worklist for improvement focus. Vaccine assessment measured via EPIC immunization tab marked as reviewed, discrete areas to document vaccination and their administration were not a part of nursing or provider’s workflow. Using the Plan, Do, Study, Act (PDSA) method, the following changes were tested: PDSA Cycle 1; A green sticker highlighted those patients needing vaccine assessment. PDSA Cycle 2; A smart phrase was created for documentation in nurses’ notes and PDSA Cycle 3; provider’s notes regarding vaccine recommendations. Results: Interventions were associated with an improvement of influenza assessment via the immunization tab marked as reviewed in the ID outpatient clinic from 73% noncompliance to 3% noncompliance from September 2023 to March 2024. Concurrent with improvement of our assessment process, our on-site vaccination rate increased from 97% error to 89% error (Table) and there was 50% improvement in provider’s documentation. Conclusions: The formation of a multidisciplinary working group and implementation of quality tools interventions resulted in timely significant improvement in vaccination assessment, documentation, and administration.

Effectiveness of integrated care models for stroke patients: A systematic review and meta-analysis.

Given that stroke is a leading cause of disability and mortality worldwide, there is an urgent need for a coordinated healthcare approach to mitigate its effects. The objectives of this study were to perform a systematic review and meta-analysis of stroke integrated care models and develop recommendations for a representative model. A systematic review and meta-analysis. The literature search identified randomized controlled trials comparing integrated care models with standard care for stroke patients. The included studies followed PICOs inclusion criteria. The qualitative analysis included creating a flowchart for the literature screening process, and tables detailing the basic characteristics of the included studies, the adherence to the ten principles and the results of the quality assessments. Subsequently, quantitative meta-analytical procedures were conducted to statistically pool the data and quantify the effects of the integrated care models on stroke patients' health-related quality of life, activities of daily living, and depression. The China National Knowledge Infrastructure (CNKI), Wanfang Data, Chongqing VIP Chinese Science and Technology Periodical Database (VIP), China Biology Medicine Disc (CBMDISC), Cochrane Library, Cumulated Index to Nursing and Allied Health Literature (CINAHL), PubMed, Web of Science, Embase, Google Scholar, and Clinical Trials were searched from inception to March 13, 2024. Of the 2547 obtained articles, 19 were systematically reviewed and 15 were included in the meta-analysis. The integrated care models enhanced stroke patients' health-related quality of life, ability to perform activities of daily living, and reduced depression. Adherence to the 10 principles varied: comprehensive services, patient focus, and standardized care delivery had strong implementation, while gaps were noted in geographic coverage, information systems, governance structures, and financial management. Integrated care models improve outcomes for stroke patients and adherence to the 10 principles is vital for their implementation success. This study's findings call for a more standardized approach to implementing integrated care models, emphasizing the need for integrated services, patient-centred care, and interdisciplinary collaboration, while also addressing the identified gaps in terms of integration efforts. This study provides evidence-based recommendations on the most effective integrated care approaches for stroke patients, potentially leading to better patient outcomes, reduced healthcare costs, and improved quality of life.

Chitosan Oligosaccharide Laser Lithograph: A Facile Route to Porous Graphene Electrodes for Flexible On-Chip Microsupercapacitors.

In this study, a convenient chitosan oligosaccharide laser lithograph (COSLL) technology was developed to fabricate laser-induced graphene (LIG) electrodes and flexible on-chip microsupercapacitors (MSCs). With a simple one-step CO2 laser, the pyrolysis of a chitosan oligosaccharide (COS) and in situ welding of the generated LIGs to engineering plastic substrates are achieved simultaneously. The resulting LIG products display a hierarchical porous architecture, excellent electrical conductivity (6.3 Ω sq-1), and superhydrophilic properties, making them ideal electrode materials for MSCs. The pyrolysis-welding coupled mechanism is deeply discussed through cross-sectional analyses and finite element simulations. The MSCs prepared by COSLL exhibit considerable areal capacitance of over 4 mF cm-2, which is comparable to that of the polyimide-LIG-based counterpart. COSLL is also compatible with complementary metal-oxide-semiconductor (CMOS) and micro-electro-mechanical system (MEMS) processes, enabling the fabrication of LIG/Au MSCs with comparable areal capacitance and lower internal resistance. Furthermore, the as-prepared MSCs demonstrate excellent mechanical robustness, long-cycle capability, and ease of series-parallel integration, benefiting their practical application in various scenarios. With the use of eco-friendly biomass carbon source and convenient process flowchart, the COSLL emerges as an attractive method for the fabrication of flexible LIG on-chip MSCs and various other advanced LIG devices.

Challenges in the Recycling of Battery Casing Materials

AbstractCurrent recycling methods for the very popular lithium‐ion batteries (LIBs) focus mainly on recovering valuable metals such as cobalt and nickel for economic reasons. The cell casing components, which are mainly made of aluminum, can make a significant contribution to achieving political recycling targets. Mechanical processes are used to separate the casing components from the overall LIB material stream. The aluminum, copper, steel, and plastic components are then further concentrated into various potential products by, e.g., magnetic separation, eddy current separation, and air classification. Considering the benefits of additional stress to compact the metal parts, the knowledge gained from the individual sorting steps can be combined to form a process flow chart.

Research on pinch analysis of union station a subsystem

To realize the cascade utilization of energy from the subsystem of Union Station A and improve the extraction of residual heat from sewage in the oilfield, this paper presents a process flow chart based on the Union Station A subsystem and analyses the energy flow of the entire Union Station A subsystem through the method of pinch analysis. In this study, we examine the energy flow distribution across the temperature spectrum within the system, identify the system’s energy consumption “bottleneck”, and optimize the system. The optimization findings reveal that the appropriate range for the pinch point temperature difference in the distributed energy system of the station is 8 to 14°C, with an associated energy-saving potential of 2.73%.

Graph-guided masked autoencoder for process anomaly detection

Developing an accurate and reliable anomaly detection model is of great significance for safe operation in the process industry. To minimize false positives, it is crucial to accurately model the intricate topological and nonlinear connections among variables. In this study, a process anomaly detection method based on graph-guided masked autoencoder (GGMAE) is proposed by introducing the concept of the graph to the process industry. GGMAE first constructs a topology graph according to the process flowchart. Then, the patch and mask mechanism forces GGMAE to learn the process intrinsic information to reconstruct the input according to the variable topological relationship and temporal characteristics. Additionally, Kullback-Leibler divergence is used as the loss to ensure that the distribution of input and output is consistent. Experiments on two publicly available anomaly detection benchmarks demonstrate the superiority of GGMAE over existing methods. Visualization of the results demonstrates the physically compliant reconstruction logic.

The End-to-End Testing of the Material Accounting and Analytical Support System of Organizations

Relevance. Economic activity of organizations in modern market conditions leads to the need of constant search of ways to improve the accounting of materials and control over their movement, as well as the management of expenditure of these resources for production, which is one of the most important sources of growth in the efficiency of production activities, the growth of competitiveness of the economic entity and its financial stability. Novelty. Many authors (S. Kukushkin, V. Pozdnyakov, O. Pshenichnikova, E. Sitikova, L. Bobrovskaya, N. Kondrakov, O. Shvyreva, N. Kazakova and others) have considered the issues of planning, analysis, accounting and control within the system of accounting and analytical support of materials, but each of them chose a specific block for research, because of which there is no holistic understanding of the process of providing the organization with the necessary working capital. The end-to-end testing is not a well-studied tool of internal control at all. The methods used in the study of the issue of development and implementation of accounting and analytical support of materials in manufacturing enterprises are analysis, modelling, deduction, concretization, description, and interview with various experts in the field of accounting, external audit and internal control. As a result of the study, a flowchart of the business process related to the acquisition, storage and disposal of inventories was developed, and the end-to-end testing was implemented as a tool to control the movement and use of such working capital in economic entities of the production organizations. These recommendations will help to make management decisions in a relevant and qualitative manner.

Application of fuzzy failure mode and effect analysis to investigate lean wastes in the sewing section

PurposeThis study aims to quantify and prioritize the main causes of lean wastes and to apply reduction methods by employing better waste cause identification methodologies.Design/methodology/approachWe employed fuzzy techniques for order preference by similarity to the ideal solution (FTOPSIS), fuzzy analytical hierarchy process (FAHP), and failure mode effect analysis (FMEA) to determine the causes of defects. To determine the current defect cause identification procedures, time studies, checklists, and process flow charts were employed. The study focuses on the sewing department of a clothing industry in Addis Ababa, Ethiopia.FindingsThese techniques outperform conventional techniques and offer a better solution for challenging decision-making situations. Each lean waste’s FMEA criteria, such as severity, occurrence, and detectability, were examined. A pairwise comparison revealed that defect has a larger effect than other lean wastes. Defects were mostly caused by inadequate operator training. To minimize lean waste, prioritizing their causes is crucial.Research limitations/implicationsThe research focuses on a case company and the result could not be generalized for the whole industry.Practical implicationsThe study used quantitative approaches to quantify and prioritize the causes of lean waste in the garment industry and provides insight for industrialists to focus on the waste causes to improve their quality performance.Originality/valueThe methodology of integrating FMEA with FAHP and FTOPSIS was the new contribution to have a better solution to decision variables by considering the severity, occurrence, and detectability of the causes of wastes. The data collection approach was based on experts’ focus group discussion to rate the main causes of defects which could provide optimal values of defect cause prioritization.
