合成回路不停车抢修冰机方案在合成氨装置上的应用

A SCHEME OF URGENT REPAIR OF REFRIGERATOR WITHOUT SHUTTING DOWN THE SYNTHETIC LOOP IN SYNTHETIC AMMONIA PLANT

在合成氨装置冰机故障需停车检修时,进行工艺调整,保持合成气压缩机及合成回路降低负荷运行,分析论证认为方案可行,实施后效果良好,增加了一定的经济效益。

During maintenance of refrigerator while its malfunction shutdown in synthetic ammonia plant,the process was readjusted to keep the synthetic gas compressor and synthetic loop operating under lower load. The scheme was verified to be feasible after execution,bringing a quite fair economic benefit.
