COMPOSITION FOR REMOVAL AND PREVENTING OF SULFURIC DEPOSITION IN GAS WELLS AND GAS PRODUCTION EQUIPMENT Russian patent published in 1995 - IPC

FIELD: gas production equipment. SUBSTANCE: composition contains compound with formula of , where R¹ and R² and C₁-C₄ are alkyl radicals, a is average number of sulfur inner atoms within the range of 0-1.5, and dimethylaminoethanol or dimethylamino-2-propanol or diethylamine or triethylamine in an amount of 0-1.5 parts by weight of composition. Composition further contains polyalkene oxiamine or polyalkene oxipolyamine in an amount of 0.1-1.5 parts by weight. Composition may further contain hydrogen sulfide or alkyl mercaptan in an amount of 0.1-1.5 % by weight. Composition is used by mixing components and supplying into well, pipe or other gas production equipment, where immense sulfuric deposits may be formed. Usage of composition allows sulfur solution efficiency to be increased by 2-15 times as compared with known compositions. EFFECT: increased efficiency in solving sulfuric depositions. 4 tbl
