Patent ID: 8882890

Claim:
An apparatus for separating liquefiable hydrocarbons from a H 2 -, hydrocarbon-containing gas stream, the apparatus comprising: a vessel comprising: a wall extending vertically and enclosing an internal volume; and a first heat exchange absorption section disposed in the internal volume and having a first tube portion disposed in a first shell portion for thermal exchange with the first shell portion, wherein the first tube portion is in fluid communication with the internal volume, and wherein the vessel is configured to position the H 2 -, hydrocarbon-containing gas stream in the internal volume below the first heat exchange absorption section and a hydrocarbon-containing liquid stream in the internal volume above the first heat exchange absorption section for countercurrent contact of the hydrocarbon-containing liquid stream with at least a portion of the H 2 -, hydrocarbon-containing gas stream along the first tube portion to separate H 2 and C 3 + hydrocarbons; and a refrigeration unit in fluid communication with the first shell portion and configured to advance a refrigerant through the first shell portion to cool the hydrocarbon-containing liquid stream and the at least the portion of the H 2 -, hydrocarbon-containing gas stream along the first tube portion to facilitate separating H 2 and C 3 + hydrocarbons and to form a chilled H 2 -rich gas stream.
