FIELD: refining of oil; methods of cleaning gas-condensate and its fractions from mercaptanes.
SUBSTANCE: proposed method of demercaptanization of gas-condensate is performed by treatment of starting material with elementary sulfur solution in presence of organic amine. Reaction mixture is preliminarily subjected to action of magnetic field at magnetic induction of 0.02-0.5 T and rate of flux of 0.025-0.250 m/s. Treatment is continued for 0.2-0.5 h. Elementary sulfur is introduced at ratio of 0.5-2 mole to 1 mole of mercaptane sulfur. Degree of demercaptanization is improved by 15%.
EFFECT: enhanced efficiency; increased productivity.
