2010年联醇装置年度大修时,对造气系统氮气循环升温工艺流程进行了改进。造气系统氮气循环升温流程技改后,循环升温时间缩短,操作简单,物料消耗低,无废液排放,还可回收再生利用部分润滑油,大幅降低了设备维修、维护费用,减少了上万元的开车费用,经济效益和环保效益显著。 During the annual overhaul of the Lianzhan plant in 2010, the process of nitrogen circulation and temperature increase in the gas production system was improved. Gasification system nitrogen cycle heating process technology, the cycle heating time is shortened, simple operation, low material consumption, no waste discharge, but also recycling part of the lubricating oil recycling, significantly reducing equipment maintenance and repair costs, reducing tens of thousands Yuan driving costs, economic and environmental benefits significantly.
