摘要:
为提高装置的自动化水平,稳定产品质量,降低能耗物耗,提高高附加值产品乙烯、丙烯收率,实现装置的效益最大化,对先进过程控制(APC)系统在催化裂解(DCC)装置和气体分离装置上的应用进行了考察。结果表明:APC系统在DCC装置和气体分离装置的投用率均达到了98%以上,集散控制系统(DCS)操作频次下降幅度达到83%;通过APC系统“卡边”优化,实现DCC装置和气体分离装置单位产品能耗降低幅度分别为1.23%,1.27%;DCC装置低碳烯烃收率提高了0.54个百分点,气体分离装置丙烯产品收率提高了0.19个百分点,可为企业创效362.7万元/a。
Abstract:
The application of advanced process control (APC) system in deep catalytic cracking (DCC) unit and gas separation unit was investigated in order to improve the automation level of the unit, stabilize product quality, reduce energy consumption and material consumption, increase the yield of high value-added products ethylene and propylene, and maximize the benefit of the unit. The results showed that the utilization rate of APC system in DCC unit and gas separation unit was more than 98%, and the operation frequency of DCS decreased by 83%. Through the "card edge" optimization of APC system, the energy consumption per unit product of DCC unit and gas separation unit was reduced by 1.23% and 1.27%, respectively. The yield of low carbon olefin in DCC unit increased by 0.54 percentage points, and the yield of propylene in gas separation unit increased by 0.19 percentage points. It could have 3.627 million yuan/a of economic benefits for the enterprise.
