Coal Chemical Industry

The rapid development of large-scale coal chemical industry needs the corresponding technical and equipment support, especially the coal to oil, methanol, synthetic ammonia, and coal to olefin and other coal chemical industry needs a large number of large coal chemical valve equipment. Among them, coal to oil (with coal liquefaction legal oil), is a key development of a new technology, coal direct liquefaction units’ process conditions are extremely critical, the requirements for the valve is very high. Coal to oil is characterized by flammable, high temperature and corrosion and wear, the corresponding requirements of the valve will be very high.
