摘要:
利用SPYRO流程模拟软件建立了140万t/a乙烯裂解装置的裂解炉机理模型,考察了混合石脑油原料掺炼芳烃抽余油,对乙烯裂解装置乙烯收率及运行周期的影响。结果表明:该模型可应用于乙烯裂解装置的原料模拟与优化;偏重混合石脑油或偏轻混合石脑油中,掺炼芳烃抽余油后,对乙烯收率影响不大;当m(偏重混合石脑油)/m(芳烃抽余油)为1∶1时,原料在炉管内停留时间最短,预计1个运行周期内,较偏重混合石脑油单独裂解的工况,可多运行2 d,1 a预计多运行8 d;而偏轻石脑油原料则无需掺炼芳烃抽余油。
Abstract:
The reaction mechanism model of 1.4 Mt/a ethylene cracker unit was established by using SPYRO process simulation software. And the effects of mixing naphtha raw material with aromatic extraction residual oil on ethylene yield and operation cycle of ethylene plant were investigated. The results showed that the model could be applied to the simulation and optimization of raw materials in ethylene cracking units.Blending aromatic raffinate into heavy mixed naphtha or light mixed naphtha, had little effect on ethylene yield. When m (heavy mixed naphtha)/m (aromatic raffinate) was 1∶1, the residence time of raw materials in the furnace tube was the shortest. It was estimated that in one operation cycle, under the condition of relatively weighted mixed naphtha cracking alone, it could extend operate time for 2 d, and 8 d in one year. However, light naphtha feedstock didn′t need to mix aromatic raffinate.
