Abstract:
A process for absorption of a hydrocarbon in a filtration bed containing a resin and in situ regeneration of said filtration bed comprising:(a) passing as a first liquid an alkanolamine/water solution containing at least one hydrocarbon through said resin bed; (b) absorbing said hydrocarbon from said first liquid onto said resin; (c) passing said alkanolamine/water solution from said resin substantially reduced of hydrocarbon; and (d) removing said hydrocarbon from said resin by passing water therethrough at a temperature between about 100Â° F. and about 250Â° F. at a pressure from about 5 p.s.i. to about 150 p.s.i. such that said hydrocarbon is substantially removed by said water passing therethrough.
