Process for the removal of carbon dioxide from flue gases and the conversion of the carbon dioxide to carbon monoxide

摘要

A cryogenic air separation unit is used to separate carbon dioxide from a flue gas stream. The temperature and pressure of the carbon dioxide are controlled so that the separated carbon dioxide coming from the cryogenic air separation unit is in a liquid phase. The liquid phase carbon dioxide is converted to carbon monoxide by safely reacting the carbon dioxide with carbon at high temperature in a plasma arc reactor. The carbon monoxide produced by this reaction has sufficient energy potential to be used as a fuel.
