Since the beginning of 2011, natural gas to methanol and 1 million tons / year of coal methanol device (except for the comprehensive utilization of construction) Limited, large methanol plant in recent years for the production of methanol to olefins project integration, so although the traditional industries with excess methanol production capacity, but capacity utilization increased gradually.

In addition, the introduction of new environmental law in 2015 after the coal to methanol as the traditional coal chemical industry by environmental regulatory pressure increase, the corresponding operating rate increase is limited, and the coke oven gas to methanol affected the supply side reform and environmental protection supervision of coke industry, the overall operating rate is limited, the current winter gas methanol device because of the natural gas supply affect the majority of raw materials in the parking state.
