摘要
合成氨装置原料天然气更换,CO_2和N_2含量增高,通过增加预脱碳装置和深冷空分装置,使原料气满足生产需求。同时针对试车和投用后出现的问题,采取相应的处理措施,使问题得到解决。
N atural gas as the feedstock for synthetic ammonia plant was changed, b ut the content of CO2 and N2 in natural gas was increased. To solve the prob lem, a pre-decarb oniz ation unit and a cryogenic air separation unit were added. P rob lems occurred during comissioning and commercial production were solved b y related measures.
