A method of removing high freeze point components from natural gas, comprises:
cooling a feed gas in a heat exchanger;
separating the cooled feed gas into a first vapor portion and a first liquid portion in a separator;
heating the first liquid portion using the heat exchanger;
separating the heated first liquid portion into a high freeze point components stream and a non-freezing components stream;
receiving at least a portion of the non-freezing components stream at an absorber tower;
receiving the first vapor portion at the absorber tower at a feed point below the at least a portion of the non-freezing components stream;
producing, using the absorber tower i) an overhead vapor product that is substantially free of high freeze point components, and ii) a bottoms product stream that includes high freeze point components and non-freezing components;
recycling at least a portion of the absorber tower bottoms stream to the feed gas upstream of the heat exchanger; and
heating the absorber tower overhead vapor product using the heat exchanger.
