Since April 6, 1917, an additional 140 ovens have been installed at Gary, bringing the capacity of that plant to 700 ovens, an additional 128 at Clairton, and 154 at Fairfield, Ala. In the last two instances, the construction of the plants was made in response to direct requests of the Government, although the Corporation bore the entire expense. At the end of the war the big company had a capacity of about 40,000,000 gallons of benzol, etc., since increased to the figure already given, 45,785,000. The Corporation’s by-products ovens constitute 25.2 per cent. of all such ovens in the United States. Its actual production is somewhat higher than this percentage, which indicates how valuable were its activities along these lines in the prosecution of the war. Although constructed largely to meet the then-existing emergency, this capacity serves a valuable end under peace conditions. In fact, as suggested elsewhere in these pages, it is only a question of time when the old wasteful beehive coke process shall have been consigned to oblivion and the newer by-product method used exclusively. Benzol, one of the principal war products, is used commercially as a motor fuel, in the manufacture of dyes, in the rubber industry, and for the purpose of enriching illuminating gas. Ammonia is used as a fertilizer (in the form of sulphate), in refrigeration, and in the chemical industry. Tar is used for heating purposes in the manufacture of steel, and for distillation by which are recovered carbolic oils, used for disinfecting; creosote oil, used as a wood preservative; anthracine oil, used in making certain dyes; and pitch, for road making, roofing, etc. The surplus gas generated in the process is used, as stated already, for heating purposes in the manufacture of steel and for municipal gas uses. Further, if the day comes when the United States will have to draw the sword again, the big company’s capacity of coke by-products will be of immense military importance.
