CRUDE OIL DEHYDRATION AND DESALTING COMPOSITION Russian patent published in 1999 - IPC

Abstract RU 2139316 C1

FIELD: oil and gas production. SUBSTANCE: composition for extensive dehydration and desalting of sulfur and high-sulfur oils and mixtures of oils with heterogeneous and mixed emulsions contains (i) propylene oxide-ethylene oxide block copolymers in solvent or (ii) block copolymers of above oxides with diethylhydroxylamine or morpholine or with high-boiling fractions (mixture of morpholine production by-products) and solvent. When composition is used in amounts 3 to 10 g/t and 30-min settling is employed, process efficiency attains 98- 100%. With regard to dehydration and protection against corrosion of structural carbon-steel materials, composition is superior to known ones by the factors 12.5 and 4-8, respectively. EFFECT: increased performance characteristics. 2 cl, 3 tbl
