1992年11月,咸阳石油助剂厂的7×10~4t/a同轴全渣催化裂化装置投产。几个月运行,各项经济技术指标均达设计要求,但液化气产率偏低,稳定系统液化气回流罐容302的压力控制波动较大,不凝气大量排出,火炬烧量较大,而且冒黑烟,直接影响液化气产率和炼厂周围居民的身体健康。为此,我们对稳定系统有关流程进行了改造。 November 1992, Xianyang Petroleum Additives Factory 7 × 10 ~ 4t / a coaxial full residue catalytic cracking unit put into operation. A few months of operation, all the economic and technical indicators have reached the design requirements, but the low rate of liquefied gas, liquid gas in the stable system back to the tank 302 pressure control fluctuations, a large number of non-condensable gas discharge, torch burning larger, And black smoke, a direct impact on the liquefied gas production rate and the residents around the refinery health. To this end, we have transformed the process of stabilizing the system.
