低温甲醇洗原料气再沸器热负荷不够的改造

TRANSFORMATION OF INSUFFICIENT HEAT LOAD IN RECTISOL FEED-GAS REBOILER

某合成氨厂低温甲醇洗装置高负荷生产时,不能提供足够的热负荷,需要投用开车再沸器才能保证热再生塔的再生效果,导致装置能耗增加。分析原料气再沸器热负荷不够的原因,提出相应的改造措施。

When the Rectisol unit in an ammonia plant operated at high load can not provide sufficient heat load,in order to ensure the regeneration effect of thermal regeneration tower it is required that a start-up reboiler be put onto stream and this has led to an addition of plant energy consumption.The causes for insuffi- cient heat load in feed-gas reboiler are analyzed and corresponding transformation measures suggested.
