Off-stream decoking of a minor portion of on-stream thermal cracking tubes

In a process for thermally cracking hydrocarbons by passing them in admixture with steam through a multiplicity of tubes arranged in parallel in a cracking furnace, the tubes being subjected to radiant heat sufficient to cause the reactants within the tube to have a temperature of 1200-1600 DEG F.,...
