甲醇煤气变换系统工艺优化

Optimization of Methanol and Coal Gas Transformation System

分析了200 kt/a甲醇煤气净化系统耐硫变换工艺在HT-L粉煤气化运行中暴露的设计缺陷,通过增加变换炉入口阀门、增加放空管线,调整管线配置、改手动阀门为自动阀门等措施,提高了变换装置生产能力、避免了煤气放空造成的损失、延长了催化剂的使用寿命,经济效益明显。

This paper introduced the design flaws exposed from the sulfur-tolerant shift process in HT-L pulverized coal gasification operation during the 200 kt/a methanol and coal gas purification system,through increasing the transformation furnace inlet valve amount and the vent pipe,adjusting the pipeline configuration,changing manual valve to automatic valve and other measures to improve the production capacity of transformation device,to avoid the loss caused by coal gas emptying,to prolong the service life of the catalyst,and in brief the economic benefit was obvious.
