FIELD: methods of oil, oil products and gas condensate clearing from mercaptans, used in oil and gas processing industry and directly at oil and gas fields for deodorization of oil and gas condensate. SUBSTANCE: aim is to decrease costs, to improve process and its ecological characteristics due to decrease of nitric acid consumption, simplification of process and exclusion of wastes. To decaptanize oil, oil products and gas condensate oxidizing mixture is used. Mixture has nitric acid and organic substances forming salt with the acid in molar ratio as 1 : (0.5 - 2.0), that is introduced in oil, oil products or gas condensate taken in ratio of 0.05 - 1.0 mole of nitric acid per ! mole of mercaptan sulfur and process is carried out under temperature of 0-90 C. Amines, amides, esters and alcohols. Method allows to exercise deodorization of oil, oil products and gas condensate till required norms. Depending upon initial conditions of process degree of demercaptanization achieves value of 30 - 100 %. EFFECT: decreased costs, improved process and its ecological characteristics. |
