Method for minimizing recycling in an unsaturated gas plant
A method is described of operating an unsaturated gas plant, wherein the plant comprises first means for receiving a low pressure gas input and for providing a liquid output and a gaseous output, an absorber for receiving an unstabilized gasoline input and a hydrocarbon oil input, a stripper and a low temperature separator for providing an overhead output to the absorber and a bottoms output to the stripper. The method consists of: (a) mixing the liquid output from the first means, the gaseous output from the first means, bottoms product from the absorber and overhead products from the stripper; (b) separating the mixture provided in step (a) into a liquid hydrocarbon portion and a gaseous portion; (c) introducing the liquid hydrocarbon portion into an upper section of the stripper; and (d) introducing the gaseous portion into the low temperature separator.
