Patent ID: 7560019

Claim:
A process for cracking liquid hydrocarbon feed in a system for cracking gaseous hydrocarbons, the process comprising the steps of: (a) feeding a liquid hydrocarbon feed stream to a thermal cracker; (b) cracking a vaporized portion of the liquid hydrocarbon feed stream in the thermal cracker to produce a cracked effluent; (c) feeding the cracked effluent from the thermal cracker to a transfer line heat exchanger (TLE); (d) feeding the cracked effluent from the TLE to a first separator; (e) separating the cracked effluent from the TLE in the first separator into a first separator bottoms stream comprising tar and a first separator product stream; (f) feeding the first separator product stream to a second separator; (g) feeding a second separator quench fluid to the second separator to quench the first separator product stream; (h) separating in the second separator, a second separator bottoms stream comprising tar and a second separator product stream comprising an olefin product; and (i) treating the second separator bottoms stream in a solvation process to separate tar from at least one of water and the second separator quench fluid.
