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.

Compositions and methods are provided for the recovery of minerals from mineral suspension, such as lime generated in Kraft pulping processes. More particularly, the composition comprises polyalkoxylate co-polymers, alkyleneamine alkoxylates, and optionally anionic surfactants, that when added to mineral dewatering process, aids in the recovery of the mineral,

The present invention provides a liquid composition of quicklime particles within an alkylene glycol-based paste or slurry environment, which allows for pumpability and meterability of a liquid composition into cementitious materials such as concrete and mortar. Treated quicklime particles of the present invention manifest an unexpected and surprising hydration induction postponement behavior, as demonstrated through calorimetric testing.

A method is shown for forming a high solids reactive lime slurry from quicklime. The timely addition of a carbohydrate and antiscalant polymer to slaking water provides desirable degree of control over the rate of reaction in which the heat of reaction is moderated to ensure the antiscalant polymer remains intact, thereby producing a fine quicklime slurry with low and stable viscosity.

Systems and Methods to produce a lime hydrate sorbent composition formed of highly reactive lime hydrate (HRH) by adding compounds to the slaking water in a method that would produce a non-HRH, which will typically be a lime hydrate having citric acid reactivity as discussed above of more than ten seconds, to make the non-HRH an HRH, which is having a citric acid reactivity of less than or equal to ten seconds.
