摘要
浅冷油吸收技术是针对炼厂干气回收利用开发的一种简单、高效的混合气体分离工艺,具有回收率高、流程简单及原料适应性强等特点。为了提高资源的综合利用率并扩大乙烯装置的原料来源,国内某石化公司采用浅冷油吸收技术设计并建设了一套20万吨/年炼厂饱和干气回收装置,用于回收炼油厂副产的焦化干气和临氢干气,将分离得到的碳二提浓气产品送到乙烯装置作为裂解原料。该装置一次开车成功,在装置运行期间,依据实际进料组成及流量的变动,及时调整和优化装置操作参数,使装置各项指标均达到了设计要求,效果良好。
The Cold Oil Absorption Technology （COAT） is a simple and efficient method for the recovery of refinery dry gas with high recovery rate, simple process flow and extensive applicability. On the basis of COAT, a unit of 200 kt/a was designed for separating C2 components from the coking dry gas and other gases in order to improve the comprehensive utilization of natural resources. Recently, this unit has been put into production successfully after initial commissioning and achieved remarkable effects.
