煤制合成液化天然气技术工艺试验研究

Experimental study on coal to liquefied natural gas technology

对煤制合成液化天然气技术工艺进行了试验研究。基于工艺流程设计基础对甲烷化催化剂进行研制,从压缩工序及净化工序、甲烷化工序、分离工序和罐区四个方面对工艺流程进行探讨。该技术的的工艺试验结果理想,各项指标均优于设计值,为煤制天然气项目的实施与推广提出了技术参考。

The technology of coal to liquefied natural gas(LNG)was studied.Based on the process design,the methanation catalyst was developed.The process flow was discussed from four aspects:compression process and purification process,methane chemical process,separation process and tank farm.The process test results of this technology are ideal,and each index is better than the design value,which provides technical reference for the implementation and promotion of coal to natural gas project.
