摘　　要：独山子石化公司为降低220 kt/a乙烯装置能耗,根据乙烯装置用能分析,结合裂解炉和裂解气压缩机的现行工况,提出将裂解炉运行模式由“6开1备”改为“5开1停1备”。为选择出裂解炉“5开1备1停”的最优运行模式,分5个阶段进行工况测试。并在乙烯装置短停开工后进行测试验证,通过对比2号汽油分馏塔(C-103)的设计参数,优化调整并固化该塔的裂解气负荷与塔中部回流、汽油回流量的关系,确保了急冷油黏度和急冷水品质稳定受控。通过裂解炉运行模式攻关,快速实现了乙烯装置节能降耗的目标。In order to reduce the energy consumption of the 220 kt/a ethylene plant in Dushanzi,it was proposed to change the operating mode of cracking furnace from 6 for operation and 1 standby to 5 for operation,1 stopped and 1 standby based on the energy consumption analysis of the ethylene plant and the current working conditions of cracking furnace and cracking gas compressor.In order to select the optimal operating mode of 5 for operation,1 stopped and 1 standby,the working conditions were tested in 5 stages.By comparing the design parameters of the No.2 gasoline fractionator(C-103),the relationship between the cracking gas load of the tower and the middle pumparound and gasoline reflux was optimized and adjusted,ensuring the stable and controlled quench oil viscosity and quench water quality.Through optimizing the operating mode of cracking furnace,the goal of energy saving and consumption reduction of the ethylene plant was quickly achieved.
