Abstract
A process for recovery hydrogen and LPG from a gaseous separated hydroprocessed stream and a stripper gaseous stream and/or a fractionator gaseous stream by increasing the pressure of the stripper gaseous stream and/or the fractionator gaseous stream. Both streams or all three streams can be subjected to sponge absorption and hydrogen recovery in series.
