甲醇弛放气制合成氨低负荷运行的解决措施

摘要

针对山东恒昌聚材化工科技股份有限公司甲醇弛放气制合成氨长期低负荷运行的问题，介绍了新建两段炉、甲醇转化炉燃料气和化产管式炉燃料气改投解吸气等3种解决低负荷运行的解决措施。结果表明：甲醇弛放气由改造前的8600 m3/h增加到13500 m3/h，液氨产量提高了57．1％，基本保证了合成氨装置的满负荷运行。%In allusion to problems existed in long-term low load operation of synthetic ammonia made by methanol releasing gas in Shandong Hengchang Jucai Chemical Engineering & Science Technology Stock Company Ltd ., author has introduced the 3 kinds of solution measures in running of solving low load operation, making combustion gas used for new-built two stage furnace, methanol conventor and tube type furnace in operation to be changed to put into desorption gas and so on.Result indicates that methanol releasing gas is increased from 8 600 m3/h before reformation to 13 500 m3/h, liquid ammonia production is increased by 57.1%,it can guarantee basically full load operation for synthetic ammonia plant .
