270. BLATCHFORD, J. W. Oxygen Replaces Air in Water-Gas Process. Chem. Eng. News, vol. 28, 1950, p. 1922. Abstract of paper presented at the chemical conference of the Am. Gas Assocn. Operation is described of a 360-ton/day O2 plant built for the DuPont Co., by Linde Air Products Co., together with several mechanical blue-gas sets. The rate of O2 feed to the generators in general was low, although in 1 test the flow averaged 2,000 cu. ft./min. for 45 hr. No loss in product quality at this high rate of gasification is reported as compared with the normal rate, which is about 25% lower. At normal operating conditions the units used about 23.7 lb. of coke, 243 cu. ft. of O2 and 32.4 lb. of steam to make a million cu. ft. of water gas. The use of O2 for this process appears to be decidedly advantageous because of the increase in capacity it permits, as well as from the standpoint of fuel consumption and maintenance of equipment. It seems probable that almost any kind of fuel can be used and almost any type of gas maker be modified to use O2. BLUM, P. See abs. 215. |
