    摘要: A method is provided for treating the effluent from a hydrocarbon pyrolysis unit processing heavier than naphtha feeds to recover heat and remove tar therefrom. The method comprises passing the gaseous effluent to at least one primary transfer line heat exchanger, thereby cooling the gaseous effluent and generating superheated steam. Thereafter, the gaseous effluent is passed through at least one secondary transfer line heat exchanger having a heat exchange surface with a liquid coating on said surface, thereby further cooling the remainder of the gaseous effluent to a temperature at which tar, formed by the pyrolysis process, condenses. The condensed tar is then removed from the gaseous effluent in at least one knock-out drum. An apparatus for carrying out the method is also provided.

    摘要: A process and apparatus for cracking liquid hydrocarbon feedstocks utilizes a vapor-liquid separator to treat heated vapor-liquid mixtures to provide an overhead of reduced residue content. Hot liquid bottoms from the separator are heat exchanged with cool hydrocarbon feedstocks for cracking to provide cooled liquid bottoms and preheated feedstock. At least a portion of the preheated feedstock is directed to a convection section of a pyrolysis furnace for additional heating and subsequent cracking.
