Coke is needed in the blast furnace as the main fuel and chemical reactant and the main product of a coke plant. The second main product of the coke plant is coke oven gas. During treatment of the coke oven gas some coal chemicals like tar, ammonia, sulphur and benzole can be recovered as by-products. Since the market prices for these by-products are rather low and often erratic it does not in most cases justify the investment to recover these products. This is the reason why modern gas treatment plants only remove those impurities from the crude gas which must be removed for technical and environmental reasons. The cleaned gas, however, is a very valuable product as it replaces natural gas in steel work furnaces and can be used by other consumers. The surplus can be combusted in the boiler of a power plant. A good example for an optimal plant layout is the new coke oven facility of Thai Special Steel Industry (TSSI) in Rayong. The paper describes the TSSI`s coke oven gas treatment plant.
