摘要
A process for the thermal decoking of cracked gas coolers for the indirect cooling, by means of water, of ethylene-containing cracked gases which are obtained by thermal cracking of hydrocarbons in the presence of steam in an indirectly heated tube cracking furnace, at cracked gas exit temperature of above 750 DEG C., in which, instead of a heated steam/air mixture, heated air, without steam, is passed through the cracked gas cooled tubes which are to be decoked.
