METHOD AND GAS TURBINE PLANT FOR DISPOSAL OF ASSOCIATED PETROLEUM GAS Russian patent published in 2015 - IPC F02C3/00 F23G5/00 

FIELD: oil and gas industry.

SUBSTANCE: method intended for disposal of associated petroleum gas containing hydrogen sulphide lies in combustion of gases in the combustion chamber and conversion of released thermal energy to electric one with collection of electric energy from the rotating turbine. Gases are burn in arranged presence of excited molecular oxygen in singlet state in the combustion chamber thus ensuring increased combustion efficiency and improved efficiency of effective energy of reagents conversion into thermal energy released at combustion; combustion products containing SO₂ are diverted and oxidised additionally up to SO₃ in additional oxidation chamber arranging additional presence of singlet oxygen; the formed products are cooled up to temperature below condensation temperature of binary aerosol H₂O/H₂SO₄; $$S{O}_3^{-},$$ $$HS{O}_4^{-},$$ H₃O⁺ ions are generated in them and condensed phase of binary sulphate aerosol H₂O/H₂SO₄ is formed, sulphate aerosol is diverted, water vapours are separated from it and condensate of sulphuric acid H₂O/H₂SO₄ is separated. The gas turbine plant comprises combustion chamber and turbine coupled to electric generator, additional oxidation chamber, gas-discharge cell coupled to combustion chamber and additional oxidation chamber, cooling unit in the form of heat exchanger, a multipoint corona discharge electrode and separator.

EFFECT: improved combustion efficiency of associated petroleum gases and disposal of sulphide-containing combustion products by their conversion to sulphuric acid.
