  On May 22, 2017, CCTV13 News Channel "News Live Room" broadcast "Shanxi Xiaoyi: 1 billion cubic meters of coke oven gas turns waste into treasure". Zhu Lihua, executive deputy director of Pengfei Coking Plant, was interviewed by CCTV reporters. Pengfei Group's 600000-ton methanol co-production 0.4 billion cubic LNG project relies on surplus coke oven gas resources generated in the coking process of 5 million-ton coke production base. After compression, purification and decarbonization, the product LNG is separated through cryogenic liquefaction at minus 170 degrees. The remaining hydrogen, carbon monoxide and carbon dioxide in the decarbonization section are compressed and mixed in the methanol synthesis system to generate methanol, thus creating a new path for the transformation and development of coal coking enterprises.
