An unsaturated gas plant system includes a first unit which receives a low pressure hydrocarbon gas input and provides a liquid output and a gaseous output, an absorber which receives an unstabilized gasoline input and a lean oil input, a stripper, and a low temperature separator which provides an overhead products output to the absorber and a bottoms product output to the stripper. A high temperature separator is provided for receiving an input which includes the liquid output and the gaseous output from the first unit, bottoms product from the absorber and overhead product from the stripper and which provides a hot liquid hydrocarbon output to an upper section of the stripper and a gaseous output to the low temperature separator after passing through a condenser. A portion of the unstabilized gasoline input to the absorber is diverted to the high temperature separator input. The diverted unstabilized gasoline can be taken directly from a main column fluid catalytic conversion system fractionator. |
