Coal Chemical

Basic Chemicals

Starting materials in Air Water's coal chemistry are “coke-oven gas” and “coal tar” obtained by high-heat processing of coal, from which many chemical products are produced. By separating and refining this “coke oven gas” to a high degree, we produce and stably supply a variety of high value-added “basic chemical products” along with the “refined gas” recovered for use in blast furnace operation.
