摘要
Two systems are combined in Armco Steel Corp. plant at Middletown, Ohio. One of the featured systems, developed by Firma Carl Still of Recklinghausen, West Germany, recovers hydrogen sulfide (H//2S) for use as feedstock for sulfuric acid manufacture. The other system, by U. S. Steel Corp. (Pittsburgh, Pa. ), recovers ammonia vapor and converts it to an anhydrous product. Plant will process 84 million ft**3/d of offgas. Coke-oven gas remaining after treatment will be a clean, 452-Btu/ft**3 fuel stream that Armco will burn in its steelmaking operations. Each cubic foot of the clean gas contains only 0. 50 grains of H//2S.
