摘要

A process for extracting and recovering Sulfur dioxide from a source gas containing Sulfur Dioxide,That includes the steps of: (i) contacting a feed gas Stream comprising the gas source in an immersive environment with an absorption of Sulfur dioxide flowing contracoThe gas feed Stream comprises an Absorbent and Malate Salt, Sulphur Dioxide,So the Absorbing Sulfur dioxide from gas Stream feeding into the middle of absorption of Sulfur dioxide and producing exhaust gas from the Sulfur dioxide has been REMForgot, along with a Liquor Enriched Sulfur dioxide Absorption; (ii) contacting the absorption Liquor enriched with Sulfur dioxide vapor Separation,In a separator Liquor Absorption,Desorbers for Sulphur dioxide Absorption Liquor from the Enriched Environment and produce an absorption of Sulfur dioxide reclaimed effluent gas separator and a primaryWhich contains water vapor and sulfur dioxide; (iii) remove the regenerated absorption of Sulfur dioxide from an outlet for Liquid separator Absorption Liquor and the effluent dGas separator and PrimaryFrom an outlet for Steam separator Liquor Absorption; and (iv) Adding acid or base by means of absorption of Sulfur dioxide in a proportion such that the PH of the liquor enriquec AbsorptionGone with Sulfur dioxide in the Absorbent base is maintained at a value between 3.4 and 4.2.
