    摘要: A process is provided for cracking hydrocarbon feedstock containing resid comprising: heating the feedstock, mixing the heated feedstock with a fluid and/or a primary dilution steam stream to form a mixture, optionally further heating the mixture, flashing the mixture within a flash/separation vessel to form a vapor phase and a liquid phase, partially condensing the vapor phase by contacting with a condenser within the vessel, to condense at least some coke precursors within the vapor while providing condensates which add to the liquid phase, removing the vapor phase of reduced coke precursors content as overhead and the liquid phase as bottoms, heating the vapor phase, cracking the vapor phase in a radiant section of a pyrolysis furnace to produce an effluent comprising olefins, and quenching the effluent and recovering cracked product therefrom. An apparatus for carrying out the process is also provided.

    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 staged-air burner for use in furnaces such as in steam cracking. The burner includes a burner tube including (i) a downstream end, (ii) an upstream end for receiving fuel and air, flue gas or mixtures thereof from a primary air chamber, and (iii) a burner tip mounted on the downstream end of said burner tube and directed to the first flame opening in the furnace, so that combustion of the fuel takes place downstream of said burner tip; a secondary air chamber for supplying a second portion of combustion air, said secondary air chamber in fluid communication with at least one air port; and a wall peripherally surrounding said burner tip to provide a barrier between a base of a flame at said burner tip and said at least one air port.
