摘　　要：为了保证GSP粉煤加压气化装置的安稳长满优运行,针对GSP粉煤加压气化激冷流程合成气洗涤系统中部分冷凝器出现的问题做出了将其切出的流程技改,将部分冷凝器同系统隔离出来,只作为合成气的一个通道。技改效果表明,切出后未对合成气含尘量造成影响,将合成气进变换系统的温度提高3~5℃,使气化炉每次导气提前10 min,节约气量33 333.33 m3/h,甲醇686 t,同时规避了蒸汽单元凝液超标的风险,可为煤化工项目合成气洗涤工艺方案提供参考。To ensure the safe and stable operation of GSP pulverized coal gasification under pressure device,resolve the problems caused by partial condenser of process flow of synthetic gas washing system in GSP pulverized coal gasification quenching process,a technical transformation to the partial condenser of washing system was conducted by cutting it out. Some condenser was taken as a channel of syngas by isolating from system. The dust content of synthetic gas was not affected by the transformation. Increasing the temperature of syngas by 3 ~5℃ before piping it into transformation system,moving up gas piping time by 10 min,the system could save syngas 3. 33 × 104m3/ h,methanol 686 t. The medium pressure boiler water and secondary high pressure steam consumption were reduced. The condensate in steam unit was also reduced.
