Methods and systems for recovery of hydrocarbons from fluid catalytic cracking slurry

A method of recovering a hydrocarbon from fluid catalytic cracking slurry, the method comprising the steps of:

• contacting a feed with a catalyst in a fluid catalytic cracking (“FCC”) reactor under conditions suitable to crack one or more hydrocarbons in the feed and generate a FCC effluent;
• separating the FCC effluent with a fractionation column to generate a product stream and a FCC slurry, wherein the FCC slurry collects in a lower portion of the fractionation column;
• drawing a FCC slurry stream from the fractionation column, wherein the FCC slurry stream is drawn from the fractionation column at a temperature of about 365° C. to about 390° C.;
• and
• separating a hydrocarbon stream from the FCC slurry stream with a vacuum distillation column.

An apparatus for fluid catalytic cracking (“FCC”), the system comprising:

• a FCC reactor configured to receive a feed and contact the feed with a catalyst under conditions suitable to crack one or more hydrocarbons in the feed and generate a FCC effluent;
• a fractionation column in fluid communication with the FCC reactor;
• the fractionation column configured to receive the FCC effluent and separate the FCC effluent into a product stream and a FCC slurry;
• wherein the FCC slurry collects in a bottom portion of the fractionation column;
• a cooling zone in fluid communication with the fractionation column, wherein the cooling zone is configured to receive a first FCC slurry stream at a first temperature from a first location of the fractionation column, cool the first FCC slurry stream, and return at least a portion of cooled first FCC slurry stream to the fractionation column;
• a separation zone in fluid communication with the fractionation column, the separation zone configured to receive a second FCC slurry stream at a second temperature from a second location of the fractionation column and separate a hydrocarbon stream from the second FCC slurry stream;
• wherein the second location is different than the first location, and the second temperature is higher than the first temperature.
