Abstract:
The present invention describes a process for fractionating the gaseous fraction leaving overhead from the fractionation column of a catalytic cracking unit (FCC) using a unit for the conversion of ethylene into propylene, in order to upgrade the ethylene contained in the fuel gas.

Claim (Index 8):
The process as claimed in  claim 3 , in which the feed ( 15 ) for the conversion unit ( 22 ) arrives at the feed-effluent exchanger ( 221 ) as a mixture with the recycled stream ( 38 ) obtained from a portion of the stream ( 27 ), in which the two mixed streams are preheated to the operating temperature, then sent to the reactor ( 223 ) of the conversion unit ( 22 ), the converted effluent ( 228 ) being sent to the feed-effluent exchanger ( 221 ), in which it is cooled by indirect exchange with the feed (combination of streams  15  and  38 ), then towards the chiller ( 230 ) in which cooling is terminated with the aid of cooling water, the cooled effluent ( 23 ) being sent to a separator ( 24 ), in which the liquid phase is separated from the gas phase, said gas phase ( 25 ) being compressed by the compressor ( 26 ) then sent to the absorption section ( 31 ), and the liquid ( 28 ) being sent to the novel absorption section ( 31 ) via the pump ( 29 ).
