Development status and future of air separation equipment in coal chemical industry

Although affected by the global financial crisis, international crude oil prices have fallen sharply, but due to the increasing depletion of international petroleum resources, the use of crude oil as a chemical raw material will eventually increase its cost significantly. Therefore, the development of coal chemical industry can effectively alleviate the contradiction between domestic oil supply and demand and ensure the safety of national oil supply.

my country has a shortage of oil resources and relies heavily on imports. Although several companies have built projects in Ordos with an annual output of 4.2 million tons of methanol and 3 million tons of dimethyl ether. It is estimated that the coal-to-liquid project will form a scale of 10 million to 20 million tons in 2015 and 40 million to 50 million tons in 2025. As a key equipment for coal chemical projects, modern coal chemical air separation equipment will become a new growth point for the air separation industry with the development of modern coal chemical engineering, and the situation is promising.
