Abstract
A method and a system for feeding a feed gas including methane (CH4) and carbon dioxide (CO2) to a cryogenic distillation column are provided herein. The method includes flowing a freeze zone CO2 vapor stream into a freezing section of the column to produce an overhead stream that exits the column. The method includes heating the overhead stream via a heating component to reduce or prevent solidification of the CO2 in the overhead stream.
