The invention comprises a process for cracking liquid hydrocarbon feed to produce cracked gaseous hydrocarbons comprising feeding a liquid hydrocarbon feed stream to an olefins furnace; cracking the liquid hydrocarbon feed stream in the olefins furnace to produce a gaseous cracked effluent stream; feeding the cracked effluent from the olefins furnace to a primary transfer line heat exchanger (TLE) having two sections; injecting a first wetting fluid in a weight ratio of wetting fluid to hot gaseous effluent tangentially into the hot gaseous effluent stream at a particular location in the second section of the primary TLE; feeding the hot gaseous effluent stream exiting from the TLE to a separator; separating a separator bottoms stream comprising tar and heavier hydrocarbons and a separator product stream comprising an olefin product; and recovering an olefin product from the separator product stream.

Method and apparatus for quenching a hot gaseous stream

A process for making lower olefins from a wide boiling range hydrocarbon feed by use of a combination of one or more vapor/liquid separation devices, and then pyrolytically cracking the vapor phase in separate sets of pyrolysis radiant tubes, thereby producing a higher level of lower olefin product.

Process for producing lower olefins from hydrocarbon feedstock utilizing partial vaporization and separately controlled sets of pyrolysis coils

A contactor/separator is formed from a vessel; an inlet for receiving a vapor/liquid mixture; an inlet for receiving a superheated vapor; a hub located within the vessel, the hub including a plurality of vanes for imparting a centrifugal motion to the vapor/liquid mixture or the superheated vapor; an outlet in a bottom of the vessel for removing liquid; and an outlet for removing vapor from the vessel. A method is also provided for heating and separating liquid and vapor from a hydrocarbon feedstock comprising introducing a hydrocarbon feedstock into a contactor/separator: introducing a superheated vapor into the contactor/separator such that it contacts and vaporizes a portion of the feedstock within the contactor/separator; separating unvaporized feedstock from vaporized feedstock in the contactor/separator; removing the vaporized feedstock and the superheated vapor through a first outlet; and removing the unvaporized feedstock through a second outlet.

Apparatus and method for superheated vapor contacting and vaporization of feedstocks containing high boiling point and unvaporizable foulants in an olefins furnace

A process for making lower olefins from a heavy hydrocarbon feed by use of a combination of thermal cracking and vapor-liquid separation, and, then, pyrolytically cracking the light fraction of the thermally-cracked heavy hydrocarbon feed to thereby produce a lower olefin product.

Process for producing lower olefins

A process for making lower olefins from a heavy hydrocarbon feed by use of a combination of two vapor-liquid separation devices, and, then, pyrolytically cracking the light fraction of the heavy hydrocarbon feed to thereby produce a lower olefin product.

Process for producing lower olefins from heavy hydrocarbon feedstock utilizing two vapor/liquid separators

A crude oil feedstock or crude oil fractions containing pitch feedstock is pyrolyzed in a pyrolysis furnace.
