Abstract

A method for converting carbon dioxide gas to liquefied carbon dioxide includes (a) receiving, in a heat exchanger, a carbon dioxide gas stream and a liquefied natural gas stream, and (b) exposing the carbon dioxide gas stream to the liquefied natural gas stream to convert the carbon dioxide gas stream to liquefied carbon dioxide, and the liquefied natural gas stream is regasified to natural gas. The natural gas exits the heat exchanger and is sent to a steam methane reformer for further processing.
