IN-SITU REMOVAL DRRLUENT FROM A GASEOUS STREAM BY INJECTION OF AN DFFLUENT SORBENT INTO DOWN STREAM OF THE COMBUSTION ZONE

摘要

Removing effluents from off-gases generated by the combustion of a hydrocarbon fuel wherein an effluent sorbent is injected in the form of a spray of a liquid solution, slurry or dry solid into the off-gas stream downstream of the combustion zone at a controlled off-gas stream temperature. The effluent sorbent may be a calcium compound, magnesium compound or both and may be used with a promoter selected from the group consisting of iron, copper, manganese, boron, aluminium, sodium, potassium, zinc, nickel compounds and mixtures thereof.
