Abstract

1,266,433. Decoking cracking tubes. ESSO RESEARCH & ENG. CO. 1 Aug., 1969 [16 Oct., 1968], No. 38645/69. Heading C5E. A process for decoking the tubes in a cracking furnace is substantially as described in Specification 1,117,562, except that hydrogen is mixed with the decoking feed. Preferred H 2 : H 2 O mole ratios lie in the range 1 : 1 to 1 : 3, and all the tubes may be decoked simultaneously.
