摘　　要：乙烯回收利用装置为中石化首套工业化装置,可有效实现干气中稀乙烯组分回收利用。该工艺应用DTL技术,在OIL-3型催化剂作用下,原料干气中稀乙烯组分进行叠合、环化脱氢等反应。装置运行过程中,催化剂活性逐渐损失,无法实现连续化生产,因此装置应用2台反应器,互为备用,切换使用。高温季节生产过程中,干气不能平衡,富余量大,需要乙烯回收利用装置连续化运行来回收燃料油、液化气等有效组分,同时可作为燃料气管网压力缓冲装置,实现平衡控制。Ethylene recovery unit is the first industrial unit of Sinopec,which can effectively realize the recovery and utilization of dilute ethylene components in dry gas. The process uses DTL technology,under the action of OIL-3 catalyst,to superposition and cyclic dehydrogenation of dilute ethylene components in raw dry gas. During the operation of the unit ,the catalyst activity gradually loses and the continuous production can not be realized. Therefore,two reactors are used in the unit,each of which is standby,and the other is switched over. In the production process of high temperature season,the company's dry gas can not be balanced and the surplus is large. Ethylene recovery and utilization device is needed to run continuously to recover the effective components such as fuel oil and liquefied gas. At the same time,it can be used as the pressure buffer device of the company's fuel pipeline network to achieve balanced control.
