摘要
报道三元制冷技术在齐鲁乙烯装置二次扩建改造过程中的首次应用,总结了试运行中开车方式的选择、接丙烯流程的修改;分析了补充加热用气相冷剂注不进乙烯精馏塔、轻冷剂节流后管道压力高制冷效果差以及由于丙烯中的微量水使系统冻堵的问题。采取措施后系统运行正常,主要操作参数达到了设计要求。
The ternary refrigeration technology was developed by ABB Lummus Ltd., based on binary refrigeration technology. It was first used in the ethylene plant of Qilu Petrochemical Company Ltd, in China. It ia analyzed that most of process parameters could not reach the design values after first commissioning After taking correction action, the system became normal, and main process parameters reached design values. The situation of commissioning, problems during operation and the measures adopted are introduced, Recommendation for handling operation problems is also made.
