ABSTRACT:
Carbon dioxide is removed from CO.sub.2 and hydrocarbon containing gaseous streams. In the instance where the hydrocarbons and CO.sub.2 are such that hydrocarbons would condense out during CO.sub.2 removal, the gas stream is treated in one or more stages to accomplish hydrocarbon composition control.
