油田燃煤电厂CO_2捕集纯化工程实践

CO2是一种温室气体,通过CO2收集、驱油技术,能将造成温室效应的气体用于提高原油采收率,同时减少工业生产中温室气体的排放。为了实现CO2的捕集纯化,胜利油田采用一乙醇胺溶液(MEA)化学吸收工艺捕集CO2。介绍了"低渗透油藏CO2驱油"重大先导试验,在胜利发电厂建设CO2捕集纯化装置,通过此装置收集稳定、廉价的CO2气体用于驱油生产实践。通过分析系统运行状况,对装置进行了一系列的试验、研究,总结了大量CO2捕集系统的工程应用经验。胜利油田CO2捕集项目,通过将大型燃煤电厂烟道气中CO2捕集纯化、安全输送等系列技术攻关,形成低能耗捕集纯化、运输的集成配套技术。

CO2 capture and purification in coal-fired power plant

CO2,known as a greenhouse gas,is recycled to improve the production of crude oil through collection and oil-driving technologies. Shengli Oilfield adopts MEA chemical adsorption process to capture and purify CO2. To develop low permeability reservoir,conduct CO2 flooding experiment. First,build capture and purification devices which capture and purify the CO2 from the large-scale coal-fired power plant. Analyze the matched CO2 conveying techniques. The actual operation experiment guides the subsequent object design.
