METHOD OF STORAGE HYDROGEN SULPHIDE- AND/OR MERCAPTAN- CONTAINING CRUDE OIL, OIL PRODUCTS AND GAS CONDENSATE IN RESERVOIR IN INERT GAS ATMOSPHERE

摘要

FIELD: gas and oil producing and oil processing industries. SUBSTANCE: method comes to filling of reservoir with oil products and storing them in inert gas atmosphere and giving out. Prior to filling, compressed air is introduced into hydrogen sulfide- and-mercaptan-containing raw material, or oil products, or gas condensate in presence of catalysts at pressure of 0.3-3.0 MPa in amount of 0.06-0.12 nm³ per mole of hydrogen sulfide or 2 moles of mercaptans C₁-C₃. Solution is kept at temperature of 10-65 C for 5-180 min. After oxidizing of hydrogen sulfide and mercaptan by oxygen from air, solution is delivered into reservoir where pressure in reduced to 0.1-0.6 MPa. Waste air dissolved in raw material and containing more than 90% of nitrogen and less than 7% of oxygen is liberated forming nitrogen cushion over liquid. Alkaline water solutions of cobalt phthalocyanines are used as catalysts. NaOH, Na₂CO₃, Na₂S, NH₃ and alkanolamines are used as alkaline agents. Consumption of cobalt phthalocyanine is 0.02-0.2 g, alkaline agent is 0.1-0.6 moles per mole of hydrogen sulfide or 2 moles of mercaptans C₁-C₃.. EFFECT: simplified storage and reduced cost of storage. 6 cl, 3 ex, 1 tbl
