Parallel quantitation of salt dioctyl sodium sulfosuccinate (DOSS) and fingerprinting analysis of dispersed oil in aqueous samples

In many jurisdictions, dispersants are included in contingency plans as a viable countermeasure that can help reduce the overall environmental impact of marine oil spills. When used, it is imperative to monitor the progression of dispersant and oil to assess their environmental fate and behaviour. Amphiphilic salt dioctyl sodium sulfosuccinate (DOSS) is the major effective component of the most commonly available dispersants, such as Corexit® EC9500A. Without proper sample preparation, dispersed oil in water samples could interfere with the accurate analysis of DOSS and easily contaminate the LC-MS system. In this work, solid phase extraction (SPE) weak anion exchange (WAX) cartridges were used to separate oil and DOSS in aqueous samples. DOSS was accurately determined by liquid chromatography coupled with a high resolution Orbitrap mass spectrometer (LC-HRMS). Oil fingerprinting analysis was conducted and total petroleum hydrocarbons (TPHs), polycyclic aromatic hydrocarbons (PAHs), and petroleum biomarkers were determined by gas chromatography-flame ionization detection (GC-FID) and mass spectrometry (GC-MS). This SPE-LC/GC-MS method was used for the analysis of oil-dispersant water samples containing a mixture of Corexit® EC9500A and a selection of crude oils and refined petroleum products. Nearly a 100% DOSS recovery was obtained for various oil-surfactant conditions. Parallel quantitation of oils with dispersants was achieved using this method. A portion of the TPH loss was possibly attributed to oil retained by the SPE column. Chemical fingerprints and diagnostic ratios of target compounds in recovered dispersed oil overall remain unchanged compared with those of all studied oils.

Decadal differences in polycyclic aromatic compound (PAC) concentrations in two seabird species in Arctic Canada

Seabirds are exposed to a variety of environmental contaminants in the Arctic. While the persistence, bioaccumulation, and toxicity of some groups of contaminants have been well-studied in seabirds since the 1970s, there is less known about polycyclic aromatic compounds (PACs). With increased vessel traffic, and potential oil and gas development in the Arctic region, there is a need to understand existing PAC exposure in biota against which to compare potential effects of anticipated increases of PACs in the marine region. Thick-billed murres (Uria lomvia) and northern fulmars (Fulmarus glacialis) collected in the Baffin Bay – Davis Strait region during the International Polar Year (IPY; 2007–08), and during a recent Strategic Environmental Assessment (2018; SEA) were examined for hepatic PAC concentrations. We found that fulmars generally had higher concentrations of PACs than the murres, but murres and fulmars sampled in 2007/08 had higher concentrations of most groups of PACs compared to birds from 2018. The one exception to this pattern was that the sum of the alkylated congeners of the heterocyclic aromatic compounds containing a sulfur atom (dibenzothiophene; ΣAHET) was significantly higher in murres in the more recent sampling period (2018) as compared to 2007/08. ΣAHETs likely reflect recent exposure to more refined petroleum products associated with small boats, such as diesel, gasoline and motor oil. This work highlights the need for longitudinal studies on PAC concentrations in biota for us to gain a better understanding of how Arctic biota are exposed to this group of contaminants, and the potential deleterious effects associated with PACs.

Exploration of Flue Gas Effluent in Petroleum Refining Processes

Petroleum sector is vital in socio-economic enhancement of any petroleum producing nation as it is the leading energy producer in industrial sectors because various refined petroleum products are globally used. In process of petroleum refining, flue gases that can cause environmental degradation and eventual ill-healths are constantly been generated. This review work aims at enhancing petroleum refinery operations, alleviating flue gas emission and encouraging low-carbon perception. It condenses scattered previous studies on composition, sources, environmental impacts and benefits of flue gas in petroleum refinery. It also offers insight into handling techniques of flue gases in the industry coupled with recommendations.

Headwinds and Tailwinds: Implications of Inefficient Retail Energy Pricing for Energy Substitution

Electrification of transportation and buildings to reduce greenhouse gas (GHG) emissions requires massive switching from natural gas and refined petroleum products. All three end-use energy sources are mispriced due in part to the unpriced pollution they emit. Natural gas and electricity utilities also face the classic natural monopoly challenge of recovering fixed costs while maintaining efficient pricing. We study the magnitude of these distortions for electricity, natural gas, and gasoline purchased by residential customers across the continental US. We find that the net distortion in pricing electricity is much greater than for natural gas or gasoline. Residential customers in much of the country face electricity prices that are well above social marginal cost (private marginal cost plus unpriced externalities), while in some areas with large shares of coal-fired generation, prices are below SMC. Combining our estimates of marginal price and SMC for each of the fuels with a large survey of California households' energy use, we calculate the distribution of annual fuel costs for space heating, water heating, and electric vehicles under actual pricing versus setting price at SMC. We find that moving prices for all three fuels to equal their SMC would significantly increase the incentive for Californians to switch to electricity for these energy services.

Optimization Model for Crude Oil Allocation in Nigeria

While oil exports contribute more than 90% of Nigeria's foreign exchange revenues, it is not clear that the allocation of more oil to export than to domestic utilization has been optimal. The country increased its refining capacity from 160 Mbpd in 1979 to 445 Mbpd in 1989, while in the same decade, oil exports as a percentage of production increased rapidly from 76% to 89%. By 2009, 99% of Nigeria's production went to export at the expense of domestic refining capacity utilization, which plummeted to 7% with the consequence that >80% of domestic consumption of refined petroleum products was imported. This paper examines the end-use of Nigeria's oil production. It proposes a framework within which the crude oil produced in Nigeria can be optimally delivered to maximize net income. A mathematical model for optimal allocation of crude oil, based on a transshipment framework, is espoused and applied to maximize net income, subjects to certain plausible constraints. The constraints identified total domestic refining capacity, offshore refining capacity, upstream oil production, and domestic refined petroleum product demand. The results indicate that the optimal product import&swapped/demand ratio ought to have ranged from 78% (2010) to 100% (2016) instead of the actual 76% (2010) to 87% (2016). Additionally, the optimum import&swapped/demand ratio could have resulted in more product imports than the actual in 2015, 2016 and 2017. However, the model results suggest that from 2018 to 2020, actual petroleum product imports have been consistent with the optimized import&swapped/demand ratio.

Identification of Key Sectors in Nigeria – Evidence of Backward and Forward Linkages from Input-Output Analysis

The input-output table provides summary information on the industrial structure of an economy in a specific period. This table contains information on the flow of goods and services between industries and economic sectors. The backward and forward links are descriptive measures of the economic interdependence of sectors in terms of the volume of transactions. Sectors with strong backwards and forward linkages are vital sectors and play an essential role in a country’s development strategy. This paper aims to construct a symmetric input-output table for Nigeria and examine the Nigerian economy’s production structure by using the results applying traditional backward and forward linkage methods developed by Chenery-Watanabe and Rasmussen. Our study identifies the key sectors with backward and forward linkages as Crop and Animal production, Manufacture of Food products, Textiles, Refined petroleum products, Chemicals, Motor vehicles, Furniture, Machinery and equipment, Wholesale/retail trade, Land transport and Telecommunication. In addition, through the constructed symmetric input-output table, sector development can be further done in line with the relationship matrix, as it serves as a conduit for investment strategy, local linkage matrix and policy development. So, for the development strategy it is very important to determine which industries possess high backward and forward linkages, then stimulating final demand or primary inputs namely of these industries could positively influence the economic activity of the country. The results from this work may be used by policy makers in terms of which sectors of the economy stimulate (for example, by means of creating extra final demand, decreasing taxes, or with the help of subsiding) in order to gain better results in the sphere of economic development of Nigeria.

Mathematical modeling of a new method of transportation of viscous petroleum products at low air temperatures

High viscosity petroleum products such as fuel oils and cracking residues are widely used as marine and boiler fuels both in Russia and in its exports. Conveying viscous petroleum products at low air temperatures has a high cost due to the unloading and cleaning processes of the transport tanks. Refined petroleum product cools and solidifies during transportation, becoming highly viscous, making it impossible to drain it without preheating to restore fluidity. Emerging difficulties are common to all countries with long winters and geographically wide areas. To justify a new method of rail transport of viscous petroleum products while maintaining their high temperature and fluidity by suppressing the natural convection of the petroleum product at the stage of filling the tanker. Temperature field calculations using the finite element method and the ANSYS R18.2 package are presented. The business process of the proposed transport method is universal for all modes of transportation. Using Petri nets and simulation modelling, it is investigated using the example of cleaning a tank car boiler from highly viscous residual oil products. You must perform these operations periodically during the operation of the tank wagon, and they are mandatory before every scheduled inspection and repair. Viscous oil products can be transported in a new way, the duration of the cleaning process of the tank wagon boiler is reduced by three times and the amount of water consumed is reduced by one and a half times.

Tandem Synthesis of Ultra-High Molecular Weight Drag Reducing Poly-α-Olefins for Low-Temperature Pipeline Transportation.

Ultra-high molecular weight poly-α-olefins are widely used as drag reducing agents (DRAs) for pipeline transportation of oil and refined petroleum products. The synthesis of polyolefin DRAs is based on low-temperature Ziegler–Natta (ZN) polymerization of higher α-olefins. 1-Hexene based DRAs, the most effective at room temperature, typically lose DR activity at low temperatures. The use of 1-hexene copolymers with C8–C12 linear α-olefins appears to offer a solution to the problem of low-temperature drag reducing. The present work aims to develop two-stage synthesis of polyolefin DRAs that is based on selective oligomerization of ethylene in the presence of efficient chromium/aminodiphosphine catalysts (Cr-PNP), followed by polymerization of the olefin mixtures, formed at oligomerization stage, using efficient titanium–magnesium ZN catalyst. We have shown that oligomerization of ethylene in α-olefin reaction media proceeds faster than in saturated hydrocarbons, providing the formation of 1-hexene, 1-octene, and branched C10 and C12 olefins; the composition and the ratio of the reaction products depended on the nature of PNP ligand. Oligomerizates were used in ZN polymerization ‘as is’, without additional treatment. Due to branched character of C10+ hydrocarbons, formed during oligomerization of ethylene, resulting polyolefins demonstrate higher low-temperature DR efficiency at low polymer concentrations (~1 ppm) in comparison with benchmark polymers prepared from the mixtures of linear α-olefins and from pure 1-hexene. We assume that faster solubility and more efficient solvation of the polyolefins, prepared using ‘tandem’ ethylene-based process, represent an advantage of these type polymers over conventional poly(1-hexene) and linear α-olefin-based polymers when used as ‘winter’ DRAs.

An input-output structural decomposition analysis of changes in China's renewable energy consumption.

Governments actively encourage renewable energy use to deal with climate change and achieve carbon emission reduction targets. It is crucial to find out the driving factors that affect the utilization of renewable energy. Therefore, based on China's 2010-2016 input-output table, this paper uses the input-output model and structural decomposition analysis (SDA) to analyze the driving factors of renewable energy changes in the production end, household end, and the aggregate economy. The results show that the changes in the consumption structure (F) is the most crucial factor for renewable energy use, followed by technology progress (T) and final demand per capita (V). Sector SEHW (supply of electric power, heat power, and water) and MCRP (manufacture of coke and refined petroleum products) are the two vital sectors to achieve China's energy transition of the production level. However, as for households, the proportion of renewable energy has been declining. Hence, the government should promote renewable energy use and achieve the green transition in production and household levels.

Multi-criteria analysis of road bitumen production processes by oxidation of refined petroleum products

Based on the DEA method, an approach has been developed for the multivariate analysis of the road bitumen production processes, allowing obtaining integral comparative assessments that ensure the ranking of processes according to various heterogeneous criteria. The main quantitative characteristics, qualitative indicators, and technological parameters of the oxidation processes are selected to form target functions when solving mathematical programming problems. Based on the CCR and Super Efficiency models of the DEA method, the problems of multivariate analysis of the efficiency of road bitumen production processes for the actual values ​​of the characteristics of raw materials and parameters of technological processes were formulated and solved, a comparative analysis of the estimates obtained for 64 bitumen samples was carried out. The results of the studies carried out make it possible to significantly expand the scope of the DEA method application and create on its basis a software package for multivariate analysis and optimization of bitumen production processes by improving the quality of the final product, reducing the resources for its production and reducing the negative impact on the environment.

Identification of freight generating industry complexes: A descriptive spatial analysis

AbstractIn this paper, a descriptive spatial analysis is carried out by identifying the geographical localisations of various industry sectors that generate freight movements at a regional level in India. The district‐level data are used to identify “industry complexes” from 21 industry sectors using the Getis‐Ord Gi* statistic. Mumbai, Thane, Pune, Raigad, and Ahmednagar of Maharashtra state emerged as complexes for most industry clusters. Findings showed that metropolitan characteristics and availability of raw materials play an essential role in districts emerging as complexes. The location of freight terminals, such as seaports, is one of the major governing factors in distributing logistics and transportation activities. Most of the districts have better transport infrastructure and logistics activities inside the complexes compared to non‐complex areas. However, a need to improve transport infrastructure and logistics in the complexes of non‐metallic mineral products and coke and refined petroleum products is found. The study can help policymakers understand the areas that need improvement, investments, and complex‐based economic development strategies.

ВОЗОБНОВЛЯЕМЫЕ ПРИРОДНЫЕ СЫРЬЕВЫЕ РЕСУРСЫ, СТРОЕНИЕ, СВОЙСТВА, ПЕРСПЕКТИВЫ ПРИМЕНЕНИЯ

The review considers the current ideas of a relatively new field of "green chemistry" in the field of chemical processing of renewable natural plant raw materials. For a number of processes, the ways, methods and some technological aspects of obtaining new compounds and reagent systems, biodegradable compositions and "green chemistry" products that are in demand in various sectors of the economy, industry and life support of society are shown. The article presents the results of the analysis of Russian and world reserves of forest resources according to authoritative modern sources and proposals for their conservation and restora-tion. The problems of biorefiling of plant raw materials are described, one of which is the val-orization of lignin-the aromatic component of the chemical composition of wood. It is pro-posed to obtain biodegradable systems and compositions based on the by-product of wood processing lignosulfonate of a neutral production method characterized by a high content of polysaccharides in the hemicellulose of the carbohydrate part of wood after the separation of cellulose. The ways of using modified cellulose products as inhibitors of salt deposition and gas hydrate formation, and the areas of their application in oilfield chemistry are shown. Lig-nin and other components of plant resources have long been the basis of various classes of fi-bers of natural origin, including plant and animal origin, artificial fibers. In the sector of cre-ating materials with new properties that have a wide range of practical applications, the review describes the production of PLA polylactide synthesized from lactic acid as a modern alterna-tive to many synthetic polymers obtained from refined petroleum products. For the products of the interaction of ammonium lactate and N-butyl alcohol, a kinetic model for the production of butyl lactate, an intermediate product of green chemistry, is described. The results of the study of a specific class of compounds – ionic liquids – traditionally considered as so-called "green solvents" are presented. An approach to the creation of a mathematical model by calculating the adsorption characteristics for evaluating the effectiveness of systems and composites based on biodegradable polymers in the direction of "green chemistry" is proposed.

Cross-country pipeline inspection data analysis and testing of probabilistic degradation models

Pipelines are the most efficient and safest means for the transportation of oil, gas, and refined petroleum products. Potentially severe consequences of pipeline failures make reliability and risk assessment an essential aspect of safe operation. However, due to limited access to industrial data, reliability and risk assessment studies often rely on experimental, synthetic, or unreliable data, which often raises questions on the proposed method’s credibility. The authors had the opportunity to access a comprehensive dataset from consecutive inline inspection (ILI) runs reporting more than seven years of degradation due to external corrosion of more than 200 km of a cross-country pipeline. This paper presents a step-by-step data processing approach and detailed statistical analysis of a cross-country pipeline’s ILI data. The paper presents stochastic models and defines the parameters required for modeling time-dependent structural integrity and risk assessment, i.e., corrosion-induced failure probability, burst pressure assessment, and containment loss. The accompanying dataset and proposed models for stochastic progress of external corrosion are hoped to serve as an essential source for pipeline risk and reliability studies.

Distribution pattern and source apportionment of trace elements in refined petroleum products

The distribution pattern and sources of trace elemental contents of refined petroleum products were determined in this study. Petroleum products comprising of petrol, kerosene, and diesel samples were obtained from different commercial gas stations in Nigeria and analyzed for V, Cr, Mn, Fe, Co, Ni, Cu, and Zn using Atomic Absorption Spectrophotometry. Results showed that Zn had the highest mean concentration of 16.16 ± 2.69 mg/L in petrol while Cu had the lowest mean concentration of 0.70 ± 0.42 mg/L in kerosene. Generally, the contents of the trace elements increased from light to heavy oil. In consonance with the results of correlation matrix, principal component analysis indicated that Cr, Ni, V, and Fe were incorporated as biophile elements during sedimentation while Cu, Mn, Zn, and Co were introduced into refined petroleum products via atmospheric deposition of metal-containing particulates and/or during refining, storage and transportation.

Bioballs carrying a syntrophic Rhodococcus and Mycolicibacterium consortium for simultaneous sorption and biodegradation of fuel oil in contaminated freshwater

Nonpathogenic effective bacterial hydrocarbon degraders, Rhodococcus ruber S103, Mycolicibacterium parafortuitum J101 and Mycolicibacterium austroafricanum Y502, were isolated from mixed polycyclic aromatic hydrocarbon (PAH)-enriched river sediments. They possessed broad substrate specificities toward various PAHs and aliphatic compounds as sole carbon sources. These strains exhibited promising characteristics, including biosurfactant production, high cell hydrophobicity, biofilm formation and no antagonistic interactions, and contained genes encoding hydrocarbon-degrading enzymes. The mixed bacterial consortium combining S103, J101 and Y502, showed more effective syntrophic degradation of two types of refined petroleum products, diesel and fuel oils, than monocultures. The defined consortium immobilized on plastic balls achieved over 50% removal efficiency of high fuel oil concentration (3000 mg L−1) in a synthetic medium and contaminated freshwater. Furthermore, the immobilized cells simultaneously degraded more than 46% of total fuel oil adsorbed on plastic balls in both culture systems. SEM imaging confirmed that the immobilized consortium exhibited biofilm formation with the bacterial community covering most of the bioball surface, resulting in high bacterial survival against toxic contaminants. The results of this study showed the potential use of the cooperative interaction between Rhodococcus and Mycolicibacterium as immobilized bioballs for the bioremediation of fuel oil-contaminated environments. Additionally, this research has motivated further investigations into the development of bioremediation products for fuel oil degradation.

Renewable energy consumption policy in Turkey: An energy extended input-output analysis

The energy sector with 70% public budget influence in Turkey is unsurprisingly one of the sectors over which most policies have been developed. Although Turkey is rich in terms of renewable energy sources such as solar, water, wind, geothermal; as the speed of the consumption of the energy generated through these resources is higher than the production, the use of other non-renewable energy sources is at stake, and increases the emission amount released into the environment depending on this type of energy used. In this study, Energy Extended Input-Output Analysis has been conducted using the data of emission occurred depending on energy use within the framework of energy economy as an interdisciplinary field of study. And research has been carried out on the mutual interdependency between energy and economy. This paper employs an analysis recently published as an input-output table of the year 2014 of Turkey and energy use emission data of the same year in the World Input-Output Database. The emission occurred as a result of one single unit of energy use in the sector of electricity, gas, steam, and air conditioning supply, which are one of the two sectors including the whole components of the energy sector in Turkey, comes first with 51.4327 TJ/million-dollar coefficient, manufacture of coke and refined petroleum products, which is the other sector, ranks at the ninth row with the coefficient of 4.4556 TJ/million-dollar. As a result of the conducted analysis, while normalized total backward energy use emission linkages coefficients (BLj) equal 10.1074 TJ for Electricity, gas, steam, and air conditioning supply sector, they are 1.1676 TJ for the manufacture of coke and refined petroleum products. Normalized total forward energy use emission linkages coefficients (FLi) are 21.448 TJ for electricity, gas, steam and air conditioning supply, yet they are 1.3941 TJ for manufacture of coke and refined petroleum products. Policies on the sustainable use of energy in Turkey have been developed through the achieved results in the content of the study. Policies by focusing on the economy and prioritizing the role of energy in providing sustainable development, preferring environmentally friendly renewable energy sources, and encouraging less production of emission, have especially been mentioned.

Review of Oilfield Chemicals Used in Oil and Gas Industry

The petroleum industry includes the global processes of exploration, extraction, refining, transportation and marketing of natural gas, crude oil and refined petroleum products. The oil industry demands more sophisticated methods for the exploitation of petroleum. As a result, the use of oil field chemicals is becoming increasingly important and has received much attention in recent years due to the vast role they play in the recovery of hydrocarbons which has enormous commercial benefits. The three main sectors of the petroleum industry are Upstream, Midstream and Downstream. The Upstream deals with exploration and the subsequent production (drilling of exploration wells to recover oil and gas). In the Midstream sector, petroleum produced is transported through pipelines as natural gas, crude oil, and natural gas liquids. Downstream sector is basically involved in the processing of the raw materials obtained from the Upstream sector. The operations comprises of refining of crude oil, processing and purifying of natural gas. Oil field chemicals offers exceptional applications in these sectors with wide range of applications in operations such as improved oil recovery, drilling optimization, corrosion protection, mud loss prevention, drilling fluid stabilization in high pressure and high temperature environment, and many others. Application of a wide range of oilfield chemicals is therefore essential to rectify issues and concerns which may arise from oil and gas operational activities. This review intends to highlight some of the oil field chemicals and their positive applications in the oil and gas Industries.
