A process for the removal of pollutants from a combustion process and,
more particularly, a process for removing pollutants such as carbon
dioxide, mercury, sulphur dioxide, nitrogen compounds and oxygen
compounds from a combustion process. The process includes the removal of
pollutants from a combustion process that produces an emission
comprising: cooling the emission to a temperature of about 200.degree.
C.; removing nitrogen, water and oxygen from the emission to produce a
gas containing a concentration of pollutants; contacting the gas with an
aqueous magnesium chloride solution, wherein a slurry mixture is formed;
and cooling the gas and the slurry mixture, wherein hydrochloric acid
vapour and a sludge are formed.
