Abstract
A gas purification system for cleaning a carbon dioxide rich flue gas generated in a boiler combusting a fuel in the presence of a gas containing oxygen. The gas purification system includes a compressor for compressing the carbon dioxide rich flue gas, a first gas cooler for cooling the compressed carbon dioxide rich flue gas, a mercury adsorber arranged downstream of the first gas cooler for removing at least a portion of a mercury content of the cooled compressed carbon dioxide rich flue gas, a second gas cooler arranged downstream of the mercury adsorber for further cooling the compressed carbon dioxide rich flue gas, and a gas drier for removing at least a portion of a water content of the further cooled compressed carbon dioxide rich flue gas.
