ZHQDS-01 Deodorization and Refining Liquid (LPG Desulfurization Synergist)ZHQDS-01 Deodorization and Refining Liquid (LPG Desulfurization Synergist) ZHQDS-01 Deodorization and Refining Liquid (LPG Desulfurization Synergist) is an aqueous solvent synthesized by the reaction of natural plant acids and alkyl alcohols. It can automatically strengthen the contact between lean alkali liquid and liquefied petroleum gas (LPG), improve the solubility of mercaptans in the extractant and further enhance the reaction activity between extractant and mercaptans. Meanwhile, it increases the oxygen solubility in rich alkali liquid to accelerate the oxidation reaction of rich alkali liquid, and improves the selectivity of mercaptan oxidation to disulfides in rich alkali liquid. With sufficient air supply, the mercaptan conversion rate can be close to 100%. In addition, it enhances the contact between back-extraction solvent oil and lean alkali liquid, and improves the extraction rate of disulfides. Compared with other additives, ZHQDS-01 LPG desulfurization synergist causes extremely low increase of COD in alkali liquid, which makes alkali residue easier to treat. The product contains no organic solvents or other volatile components, and features excellent chemical stability. There is no need to inject phthalocyanine cobalt during alkali preparation, which effectively reduces operating costs.
