ABSTRACT:
An improved method and apparatus for control of a multi-pass pyrolysis furnace, e.g. for the pyrolysis of hydrocarbon feed to produce an effluent with a high ethylene content is disclosed. The method which is suitable for computer control involves the analysis of the effluent from each pass and controlling pyrolysis conditions in each pass in response to the analysis of the output from that pass. Improved optimization is possible over methods which depend on average analysis from several passes because of the wide variations which occur in cracking conditions in several passes.
