- 摘要：温室效应产生的问题已引起全球的重视。在国家双碳目标背景下，中国石油已将低碳纳入发展战略。在此背景下，各炼化企业积极开展低碳减排工作。中国石油某炼化企业在原油加工量每月提高至60×104 t以上时，H2需由尿素合成装置的合成气单元提供，导致该单元10 000 m3/h 的 CO2无处可用，只能做放空处理，从而增加了该公司的环保压力。为缓解此问题，该公司新建了1套液态CO2回收装置，将放空的CO2回收制成液态CO2产品出售，增加公司产品多样性及经济效益的同时，也具有明显的环保效益。
Abstract: The problems caused by the greenhouse effect have attracted global attention. Under the background of China's dualcarbon goals, China National Petroleum Corporation (CNPC) has incorporated low-carbon development into its strategic plan. In thiscontext, various refining and chemical enterprises are actively engaged in low-carbon emission reduction efforts. When the crude oilprocessing capacity of a certain refining and chemical enterprise of CNPC increased to over 600,000 tons per month, the hydrogenneeded to be supplied by the synthesis gas unit of the urea synthesis plant, resulting in 10,000 m3/h of CO2 from the unit becomingsurplus and having to be released into the air, which increased the environmental pressure on the company. To alleviate this issue,the company built a new liquid CO2 recovery plant to recover and convert the released CO2 into liquid CO2 products for sale. This notonly increased the diversity and economic benefits of the company's products but also had significant environmental benefits.
