Abstract
An improvement in a Ryan/Holmes separation of methane from carbon dioxide is disclosed wherein the upper portion of a distillation column is operated, i.e., -70.degree. F., while still effectuating a separation of methane from carbon dioxide. This is achieved by increasing the amount of nonpolar liquid agent added to the condenser of the column to an amount sufficient to maintain the condenser and all portions of the column above such temperatures.
