Process-based volatile organic compound emission inventory establishment method for the Petroleum Refining industry
Journal of Cleaner Production, 2020Co-Authors: Yeye Liu, Feng Han, Wei Liu, Xiaowei Cui, Xiaoyu Luan, Zhaojie CuiAbstract:Abstract The Petroleum Refining industry is an important contributor to industrial volatile organic compounds (VOCs) emission. As a foundational work for VOCs control, previous VOCs inventories usually treated the Petroleum Refining industry as an integrated part resulting the unknown of VOCs emission characteristic among different units. Refined management has becoming an inevitability with the increasing strictness of environment standards. This study aims to develop a holistic method for VOCs emission inventory of the Petroleum Refining industry toward specificity, accuracy and economization, in which a source categorization was proposed from unit angle, and a systematic estimation method was developed from the material flow point of view. This method provides a more specific and accurate quantification method, especially for fugitive emission sources which is a pivotal but difficult problem in VOCs inventory establishment. Through application to a typical medium-scale refinery located in northern China, a unit-specific VOCs emission inventory with 48 emission sources and respective local VOCs emission factors (EFs) was established. Estimation results and economic cost of the developed method were compared with those of other methods. In this study, the integrated EF was 0.77 kg-VOCs/t-crude oil refined, which was in the same order with most previous studies. Inventory results implied that increasing hydrotreating unit, reducing chemical device and solvent-used unit (e.g., polypropylene production, furfural Refining unit), upgrading catalytic reforming unit were beneficial to control VOCs emissions in this study. Using floating-roof tanks rather than fixed-roof tanks is an effective way to reduce VOCs emissions from storage tanks, which decrease 72%–86% of diesel storage emissions. Economic cost analysis showed that the advantage of this method lied in lower labor cost, and no subsequent monitoring cost. Suggestions proposed from this study provide feasible measures for local policy makers to control VOCs emission and determine abatement strategies of the Petroleum chemical industry. Meanwhile, this study greatly helps enterprises promote the fine management of VOCs-containing materials from the overall processes to identify VOCs control emphasis.

Life cycle assessment of Petroleum Refining process: A case study in China
Journal of Cleaner Production, 2020Co-Authors: Yeye Liu, Xiaowei Cui, Xuejun Yan, Sulian Gao, Zhaojie CuiAbstract:Abstract Climate change mainly caused by transportation fuel consumption has attracted global concern. In life cycle environmental burdens generated from transportation fuel production, Petroleum Refining stage is the hotspot. However, the in-depth environmental analysis of Petroleum Refining is very limited. China is the second largest Petroleum Refining country, so it is very essential to break Petroleum Refining stage into specific unit to analyze how Chinese refinery can be improved in environment performance. To achieve this goal, a systematic life cycle analysis of the environmental burden generated from Petroleum Refining process was conducted to identify the control emphasis and seek potential improvement measures. Sensitive analysis and volatile organic compounds (VOCs) emission characteristics were additional discussed to improve the accuracy of results. The significant burdens generated from Petroleum Refining process were freshwater ecotoxicity and climate change. Crude oil extraction and transport dominated most environmental categories, which indicated that the environmental problem exist in upstream supply chain. Catalytic cracking, feedstock and product handling, catalytic reforming, crude oil distillation, cooling water system and diesel hydrotreating were the major control units due to their direct emissions and electricity consumption. VOCs (e.g., acrolein and chlorofluorocarbons) produced from refinery fugitive emissions were the main substances for refinery to reduce human toxicity, ozone depletion and photochemical oxidant formation influences. 14% of Climate change were derived from organic chemicals emission in this study, which suggested that VOCs-related carbon emission should be involved in current carbon accounting work or greenhouse gases (GHGs) studies on the Petroleum Refining industry. The identified control emphasis included equipment leaks from core Refining units, storage tank emissions control, energy structure optimization and catalysts consumption intensity reduction. Some feasible and useful reduction measures targeted the control emphasis were proposed for policy makers and refinery managers to formulate reduction strategies and improve the sustainability of the petrochemical industry.

process technology in the Petroleum Refining industry current situation and future trends
Computers & Chemical Engineering, 2003Co-Authors: Lincoln F L MoroAbstract:Abstract This paper analyzes the technology of process and production optimization in the Petroleum Refining industry. There is, virtually, no refiner nowadays that does not use advanced process engineering tools to improve business results. The degree of maturity of those tools varies greatly, and there are still many unsolved problems. For instance, advanced process control is considered a mature technology, while the automatic generation of a scheduling of refinery operations is considered a goal to be achieved only in mid-term. The current state of these technologies as well as the current needs of the industry and the expected future trends are presented.

energy conservation potential in china s Petroleum Refining industry evidence and policy implications
Energy Conversion and Management, 2015Co-Authors: Boqiang Lin, Xuan XieAbstract:China is currently the second largest Petroleum Refining country in the world due to rapid growth in recent years. Because the Petroleum Refining industry is energy-intensive, the rapid growth in Petroleum Refining and development caused massive energy consumption. China’s urbanization process will guarantee sustained growth of the industry for a long time. Therefore, it is necessary to study the energy conservation potential of the Petroleum industry. This paper estimates the energy conservation potential of the industry by applying a cointegration model to investigate the long-run equilibrium relationship between energy consumption and some factors such as energy price, enterprise scale, R&D investment and ownership structure. The results show that R&D investment has the greatest reduction impact on energy intensity, and the growth of market participants (i.e. the decline of the share of state-owned companies) can improve energy efficiency of this industry. Under the advanced energy-saving scenario, the accumulated energy conservation potential will reach 230.18 million tons of coal equivalent (tce). Finally, we provide some targeted policy recommendations for industrial energy conservation.
