裂解液化气对扬子乙烯装置的影响与对策

IMPACT OF CRACKED LIQUEFIED PETROLEUM GAS ON ETHYLENE PLANT IN YANGZI AND THE COUNTERME ASURES

介绍了中国石化扬子石油化工有限公司乙烯联合装置将液化气(LPG)作为裂解原料使用的基本情况。通过使用SPYRO软件模拟计算,结合装置实际运行状况,阐明了LPG的引入有助于提升装置的乙丙收率,是一种优质的裂解原料。同时,针对LPG投入量不断增加给装置运行带来的问题,经过分析并针对性的提出对策,进而消除装置运行瓶颈,提升装置绩效水平,确保装置长周期稳定运行。

The basic situation of using liquefied petroleum gas(LPG)as the cracking raw material for the ethylene plant at SINOPEC Yangzi Petrochemical Co.,Ltd.is introduced.Combined with the actual operating conditions of the plant,SPYRO is used in the simulation to demonstrate that the introduction of LPG helps improve the ethylene-propylene yield of the plant,so LPG is high-quality cracking material.Simultaneously,to solve the problems brought by the increasing amount of LPG to the operation of plant,some countermeasures are proposed based on analysis,so as to eliminate the bottleneck of plant operation,improve the plant performance and ensure the long-term and stable operation of the plant.
