Abstract: Method of deodorizing in order to remove malodorous compounds which are present in or formed from a liquid formulation containing at least one compound bearing a thiol functional group, of formula:HS--A--Y--B (I)in which:1) the liquid formulation is placed in contact with an inert membrane which is permeable to the malodorous compounds and impermeable to the compound(s) of formula (I); and2) the malodorous compounds which have passed through the membrane are placed in contact with at least one chemical substance reacting with the said malodorous compounds and/or with at least one physical adsorption substance having a large specific surface area which binds the said malodorous compounds.

Abstract: A flue gas scrubber for removing sulfur from flue gas. This scrubber, whether a horizontal or a vertical scrubber and whether a dry or a semi-dry scrubber, incorporates a recycle line that separates heavier dry solid particles from the finer particles still entrained within the cleaned flue gas. This recycle conduit then delivers these removed dry solid particles back to the scrubber for re-injection therein so as to reduce the drying time of the reagent slurry sprayed within the scrubber. Such drying time is reduced by the recycle of these dry solids because of the increased surface area overwhich the reagent is now sprayed.
