ABSTRACT:
Coronene deposits are removed from a heat exchange zone disposed in two parallel trains of heat exchangers in a reforming process by reducing the flow of reforming zone effluent in one of the trains of heat exchangers sufficiently to effect condensation of a portion of the reforming zone effluent in said one train of heat exchangers where the coronene is deposited while simultaneously increasing the flow of reforming zone effluent in the second train of heat exchangers. Control means are provided in each of the heat exchange trains.
