Sum-Up of Start-Up Technology for Low-Pressure Integrated Methanol System in Ammonia Plant

简述了100 kt/a低压联醇系统的甲醇合成原理、工艺流程、催化剂升温还原、轻负荷生产及正常生产情况。通过加强工艺控制和及时采取措施处理非正常工况,使低压联醇系统各项工艺指标均达到了设计要求,吨醇可副产蒸汽1.2 t以上。

A brief account is given of a low-pressure integrated methanol system of 100 kt/a, with respect to the methanol synthesis principle, process flow, catalyst reduction by heating, light-load production and normal production. By intensifying process control and taking measures in time to handle improper work conditions, all process indices of the system meet the design requirements, and for a ton of methanol over 1.2 tons of steam is generated as a coproduct.
