摘要：A method for improving efficiency of sponge absorption includes providing coldflash drum liquid to an inlet of a cold stripper to produce a cold stripper net overheadvapor stream rich in liquid petroleum gas, and separately providing hot flash drum liquidto an inlet of a hot stripper to produce a hot stripper net overhead vapor stream rich inhydrogen. The cold stripper net overhead vapor stream and the hot stripper netoverhead vapor stream are separately routed to a sponge absorber to recover a liquidpetroleum gas output stream using sponge oil. In particular, the cold stripper netoverhead vapor stream and the hot stripper net overhead vapor stream are separatelyrouted to the sponge absorber at different tray locations.
