海上天然气除重烃方案比选
|
摘要
为设计渤海某油田的除重烃流程,对渤海地区现有的天然气处理系统进行适用性分析,对2种低温分离法、膜分离技术以及活性炭吸附技术进行比选分析。研究发现:满足设计要求的低温分离法工艺成熟,但该流程比较复杂、设备多、占地大,不适合海上平台使用;膜分离技术设备简单,操作费用低,推荐使用。
In order to design the scheme of heavier hydrocarbon removing for a Bohai oilfield,the existing natural gas processing system applicability on the Bohai region is analyzed and the scheme comparison and selection is made on the two kinds of low temperature separation,membrane separation technology,and the analysis of the technologies of activated carbon adsorption.The study found that the design requirements of low temperature separation technology mature are met,but the process is more complex,more equipment,covering an large area,which is not suitable for offshore platform,membrane separation technology is of simple and low operation cost,which is recommended to use.
