Process for treating flue gases in a circulating dry scrubber device wherein flue gases containing pollutants pass to a reactor where said flue gases contact a sorbent comprising high pore volume and high specific surface area slaked lime or hydrated lime being further sent to a particulate control device where said sorbent particles are separated from said flue gases substantially depleted in pollutants and form respectively a flow of flue gases substantially depleted in pollutants and a flow of sorbent particles being recycled and returned to said reactor.

Process for treating flue gases in CDS flue gas treatment

A method for treating a gas is shown which includes the steps of: injecting a powdered compound into the gas line, injecting an aqueous phase in droplet form into the line, capturing pollutants from the gases, and recovering the powdered compound separately. The step for injecting an aqueous phase in droplet form is done so as to moisten those particles of powdered compound in the gas line, when they are injected.

Method and device for treating gas by injecting a powdered compound and an aqueous phase

The invention relates to a solid mineral composition of heavy metals, in particular mercury, in flue gas, to a method for preparing such a solid mineral compound and to the use thereof for reducing heavy metals, in particular mercury, in flue gas, by placing the flue gas in contact with the solid mineral composition.
