  • Publication number: 20220305454
    Abstract: The present invention is related to a process for manufacturing a sorbent suitable for a use in a circulating dry scrubber device comprising the steps of: providing quicklime and water in an hydrator; slaking said quicklime via a non-wet route in the hydrator; collecting a lime based sorbent at an exit of the hydrator. The process is characterized in that it comprises a further step of adding at least a first additive comprising: a compound comprising silicon, and/or, a compound comprising aluminum, and/or a compound comprising silicon and aluminum before or during said slaking step, at a molar ratio between silicon or aluminum or a combination thereof and the calcium provided to said hydrator equal to or below 0.2 and equal to or above 0.02. In some other aspects, the present invention is related to a sorbent, a premix, and a flue gas treatment process.

  • Patent number: 9579601
    Abstract: 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.
