| titleOfInvention | Method of determining content of sulphides in deposits in oil-field equipment |
| abstract | FIELD: oil and gas industry.SUBSTANCE: invention relates to development and operation of oil deposits. Method provides antioxidant treatment of samples taken for analysis of 5-8 % solution of ascorbic acid, subsequent treatment of suspended sample with 20 % hydrochloric acid in apparatus for determining hydrogen sulphide in nitrogen atmosphere, which is passed through bubbler, providing its controlled supply and continuous filling of plant, distillation of released hydrogen sulphide H2S and calculation of its total amount by results of iodometric titration. Calculation of percentage content of sulphide ions in sample is carried out by formula: [S2-]%=[H2S]⋅0.016, where [H2S] – amount of mg-equivalents of hydrogen sulphide in 100 g of sediment sample; 0.016 is weight of one mg-equivalent of sulphide-ion, and calculation of iron sulphide concentration by formula: [FeS]%=[H2S]⋅0.044, where 0.044 – weight 1 mg-equivalent of iron sulphide.EFFECT: higher accuracy of analysis with simultaneous improvement of safety measures.1 cl, 1 dwg, 2 ex |
