Abstract

The contribution of greenhouse gas emissions from crude oil refineries to the global climate change has been so problematic. The end results of this has been linked to global warming causing adverse effects on public health and making the environment unsafe for living. This review article examines the challenges and effects emanating from the release of greenhouse gases from crude oil refining operations. In-depth discussions and salient points, shedding light for prospective researchers on the critical areas that should be investigated and improved on to attain net-zero emissions in refinery, were presented. The effects of the increase in the global number of refineries on GHG emissions trend in top countries are discussed. Top 10 countries and refinery industries with the highest GHG emissions were referenced as case studies. Between 2000 and 2021, the cumulative GHG emissions from refineries attained 34.1 Gt due to increase in the number of refineries while the top 10 enterprises accounted for approximately 33.8–38.1 %. Accumulative reduction of 532 Mt and 928 Mt of CO2 emissions are expected between 2020 and 2030 if the efficiencies of refineries in the top 10 countries and global refineries are respectively improved. Technologies such as hydrogen-based refining and carbon capture, utilization, and storage (CCUS); integration of circular economy principles; green financing and government-backed incentives; and government-based policies are some of the steps that can be taken to make reduction of GHG emissions from refineries a reality. In conclusion, the stated vital points regarding future prospects towards attaining net-zero emissions from crude oil refinery plants will be beneficial for prospective researchers and the entire globe.
原油精炼厂实现温室气体零排放的未来展望
原油炼油厂排放的温室气体对全球气候变化的影响一直是如此成问题。其最终结果与全球变暖有关,对公众健康造成不利影响,使环境不适于生活。本文综述了原油炼制过程中温室气体排放所带来的挑战和影响。提出了深入的讨论和要点,为未来的研究人员揭示了应该调查和改进的关键领域,以实现炼油厂的净零排放。讨论了全球炼油厂数量的增加对主要国家温室气体排放趋势的影响。以温室气体排放量最高的前10个国家和炼油行业为例进行了研究。2000年至2021年间,由于炼油厂数量的增加,炼油厂的累计温室气体排放量达到34.1亿吨,而前10家企业约占33.8-38.1 %。如果前10个国家和全球炼油厂的效率分别得到提高,预计在2020年至2030年期间累计减少5.32亿吨和9.28亿吨二氧化碳排放量。氢基精炼和碳捕集、利用和封存(CCUS)等技术;循环经济原则的整合;绿色融资和政府支持的激励措施;以政府为基础的政策是可以采取的一些步骤,以减少炼油厂的温室气体排放。综上所述,关于实现原油炼油厂净零排放的未来前景的要点将有利于未来的研究人员和整个全球。
