在中国明确了到2020年减排目标的形势下,炼油厂作为一个大的排放源,承担着重要的减排任务。将炼油厂捕集的CO2用于提高原油采收率(EOR),构建CO2-EOR产业链,不仅可以实现减排的目的,还可为炼油厂及油田带来经济和社会双重效益。将CO2-EOR产业链分为CO2回收、运输、EOR 3个单元,建立了快速有效的经济评价模型。结果表明,在偏保守、适中、较乐观情景下,产业链的CO2成本分别为411.12、376.30和361.16元(RMB)/t;CO2回收单元费用最高,约占总费用的70%,其后依次是运输费用和EOR费用;产业链计算期内,油藏可完全埋存炼油厂捕集的CO2;基于国际油价(90 USD/bbl),在较乐观情景下,产业链不仅可以补偿全部费用,还有约13亿元(RMB)的盈余,经济效益可观。
Refining China’s emission reduction targets by 2020, the refinery, as a major source of emissions, undertakes important emission reduction tasks. The use of CO2 captured by refineries to increase oil recovery (EOR) and build a CO2-EOR industrial chain can not only achieve emission reduction but also bring economic and social benefits to refineries and oilfields. The CO2-EOR industrial chain is divided into 3 units of CO2 recovery, transportation and EOR, and a fast and effective economic evaluation model is established. The results show that CO2 costs of the industrial chain are 411.12, 376.30 and 361.16 RMB / t respectively under the conservative, moderate and optimistic scenarios. The cost of CO2 recovery unit is the highest, accounting for about 70% of the total cost, followed by Is the transportation cost and EOR cost; in the calculation period of the industrial chain, the oil depot can completely trap the CO2 captured by the refinery; based on the international oil price (90 USD / bbl), in the more optimistic scenario, the industrial chain can not only compensate the full cost, There are about 1.3 billion yuan (RMB) of the surplus, substantial economic benefits.
