摘　　要：由于1号裂解炉A急冷器(L-101A)出口温度长期运行波动大,易导致裂解气二次反应结焦及影响后系统。对急冷器冷却介质进行更换,将原有工艺水改为精致水,并进行改造前后实际数据对比分析。通过优化冷却介质稳定了急冷器出口温度,延长1号裂解炉A急冷器(L-101A)清焦周期。The long-standing problem of the great fluctuation in outlet temperature of the quench cooler A( L-101 A) in the No. 1 cracking furnace easily led to the coking during the secondary reaction of cracking gas and affected the subsequent system. The cooling medium of the quench cooler was replaced,the original process water was changed to purified water,and the actual data before and after the transformation was compared and analyzed.The outlet temperature of the quench cooler was stabilized by optimizing the cooling medium,and the decoking cycle of the quench cooler A( L-101 A) in the No. 1 cracking furnace was prolonged.
