一、概况催化裂化装置是炼油厂中消耗能量较大的工艺装置,其中再生器的放空热烟气蕴藏着很大的能量,回收这部份烟气能量,对于降低装置能量消耗,提高催化裂化技术水平具有十分重要的意义。我厂催化裂化装置原处理量为60万吨/年,反应再生压力为0.7公斤/厘米~2(表),1979年7月进行了改造,反应再生压力提高到1.6～1.7公斤/厘米~2(表),处理量提高到75万吨/年。我厂催化裂化烟气能量回收工业试验工程是北京石油设计院、中国科学院力学研究所、石油化工科学研究院、陕西化肥研究所、上海炼油厂等单位的共同努力于1979年7月全部完成
I. Overview Catalytic cracking unit is a refinery consume more energy in the process unit, in which the regenerator vent hot flue gas contains a lot of energy to recover this part of the flue gas energy, reduce the energy consumption of the unit to improve the catalytic cracking Technical level is of great significance. The original capacity of catalytic cracking unit in our plant was 600,000 tons / year, and the reaction regeneration pressure was 0.7kg / cm ~ 2 (table). In July 1979, the reforming was carried out and the pressure of reaction and regeneration increased to 1.6 ~ 1.7kg / cm ~ 2 (Table), the processing capacity increased to 750,000 tons / year. I plant catalytic cracking flue gas energy recovery industrial test project is Beijing Petroleum Design Institute, Chinese Academy of Sciences Institute of Mechanics, Institute of Petrochemical Technology, Shaanxi Institute of Chemical Fertilizer, Shanghai refinery and other units of the joint efforts in 1979 July completed
