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 1):
A device for fractionating the gaseous fraction leaving the head of the fractionation column of a catalytic cracking unit, the fraction containing LPG, light gasoline, and a residual gas termed \u201cfuel gas\u201d which itself contains a certain quantity of ethylene, the device comprising:\n a first absorption section ( 6 ) which can be used to separate the fuel gas ( 15 ) and the light gasoline and LPG stream ( 10 ), said section being present in an existing catalytic cracking unit, \n a unit ( 22 ) for the catalytic conversion of ethylene into propylene and other products of interest, wherein the feed is constituted by the fuel gas ( 15 ), in which a large portion of the ethylene is essentially converted into propylene and also into aromatics and other products of interest, in the presence of a catalyst based on zeolite, \n a novel absorption section ( 31 ) which admits the effluents from the conversion unit ( 22 ) after recompression, the propylene, butene and the gasoline fractions contained in said effluents being recovered in said novel absorption section ( 31 ), by using the gasoline arriving from the existing debutanizer ( 11 ), \n a second absorption section ( 16 ), which admits the gas ( 33 ) obtained from the novel absorption section ( 31 ), \n a debutanization section ( 35 ) which admits the LPG and gasoline fractions ( 34 ) obtained from the novel absorption section ( 31 ) and which produces a stabilized gasoline ( 36 ) and a light LPG fraction ( 37 ).
