How does Ansteel's coal chemical capacity shape China's coal tar supply landscape?
Ansteel Group, a central SOE based in Anshan, Liaoning, is a major integrated coal tar producer. Its Chaoyang Steel subsidiary operates a coking plant with 1 million tons of dry coke quenching capacity, producing 33,600 tons of coal tar and 11,000 tons of crude benzene annually. More significantly, Ansteel Chemical Technology, established in 2012, processes 540,000 tons of coal tar and 150,000 tons of crude benzene per year across two tar refining units and four coke oven gas purification trains. This scale reflects the broader industry trend toward large, centralized tar processing, which improves extraction efficiency but also concentrates supply in northern China, where most coking capacity is located.
