The starting point of the project is the first station of Hangjin Banner, Ordos City, Inner Mongolia Autonomous Region. The whole line passes through 9 urban areas of 4 provinces, autonomous regions and municipalities directly under the central government, including Inner Mongolia Autonomous Region, Shanxi Province, Hebei Province and Tianjin city
The coal to natural gas pipeline filter is invested and constructed by CNOOC gas and Power Group Co., Ltd. The proposed Mengxi coal to natural gas export pipeline project will transport the coal to natural gas in Ordos, Inner Mongolia and Datong, Shanxi to the "public channel" in Beijing Tianjin Hebei and Bohai rim. SNG projects in the upstream of Mengxi coal to natural gas export pipeline are mainly concentrated in the west of Inner Mongolia and Datong area of Shanxi Province
On April 25, 2016, the environmental impact report of 4 billion cubic meters / year coal to natural gas filtration project of Inner Mongolia Beikong Jingtai Energy Development Co., Ltd. was approved by the Ministry of environmental protection; on March 4, the environmental impact report of Shanxi Datong low metamorphic bituminous coal clean utilization demonstration project (4 billion cubic meters coal to natural gas project of CNOOC) was approved by the Ministry of environmental protection
