摘要
某公司在3.0 Mt/a蜡油催化裂化装置上使用MIP-CGP专用催化剂进行了大比例掺炼脱硫渣油(掺渣)的工业试验.结合掺炼期间的主要操作参数、原料和产品性质、物料平衡及装置能耗等,对装置运行情况进行了分析和总结.结果表明,MIP工艺蜡油催化裂化装置在大比例掺炼脱硫渣油时,反应温度及催化剂烧焦控制良好,装置实现了长周期运行目标,有效降低了装置能耗,提高了装置加工负荷,为提高渣油加氢装置负荷以及全厂负荷提供了一条有效途径.
Abstract
MIP-CGP special catalyst was used in a 3.0 Mt/a gas oil catalytic cracking unit to carry out industrial test of blending desulfurized residue in a large proportion.Based on the main operating parameters,properties of raw materials and products,material balance and energy consumption during the blending period,the operation of the device was analyzed and summarized.The results showed that the reaction temperature and catalyst scorch were well controlled when the large proportion of desulfurized residue was blended in the MIP process FCC unit,the goal of long-term operation was realized,the energy consumption of the unit was effectively reduced,and the processing load of the unit was increased,which provided an effective way to increase the load of the residue hydrogenation unit and the whole plant.
