Abstract:

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.

Key words: liquefied petroleum gas/LPG, yield, SPYRO, light, impact
