Abstract: The present invention provides a process for the purification and concentration of a partially water-soluble organic product from a source containing the same at concentration C0, which process comprises the steps of: (i) concentrating said product by means of a resin to form a first aqueous solution at concentration of C1; and (ii) fractionating an aqueous solution by temperature adjustment to form a second aqueous solution and a third aqueous solution with concentrations C2 and C3, respectively, wherein C2>C3 and C2>C1>C0.

Abstract: A process for desulfurizing an SO2-comprising gaseous stream comprising the steps of: a. providing an aqueous feed comprising an anion selected from a group consisting of carbonate, bicarbonate, hydroxide, sulfite, and hydrogen sulfite; b. providing an SO2-comprising gaseous feed; and c. contacting the aqueous feed and the gaseous feed to generate a desulfurized gaseous product comprising less than 40% of the feed SO2 content, and an aqueous product; wherein the contacting is carried out in a cyclone unit comprising a housing defined by a cylindrical peripheral wall and provided with at least one inlet opening for receiving fluids thereinto and with at least one swirling means, and wherein the cyclone unit is characterized in that the velocity of the gaseous stream inside the cyclone unit is between 20 m/sec and 120 m/sec.
