合成氨工艺氨加热器换热效率下降的原因

摘要

分析合成氨工艺中氨加热器这一特殊换热设备换热效率下降的原因，根据现象提出相对应的措施，着重对甲醇溶液进行分析，结果表明：甲醇中水含量高是换热效率下降的主要原因。%Analysis of ammonia.- ammonia process heater heat exchanger heat exchanger efficiency of this particular reason for the decline, according to the site corresponding to the phenomenon of the measures proposed, focusing on the methanol solution analysis to identify the root causes of decline in efficiency of heat transfer.
