METHOD OF CLEANING CRUDE OIL FROM SUSPENDED IMPURITIES Russian patent published in 2003 - IPC

Abstract RU 2196805 C1

FIELD: crude oil treatment. SUBSTANCE: method consists in heating crude oil and cleaning it in centrifuge, at least two viscosity measurements being performed at different temperatures, and oil heating temperature ensuring specified quality of product (T) is found from equation: , in which u denotes viscogram slope coefficient ; t and t0 are oil temperatures, °C; ν, νo are kinematic viscosity values, cSt; c required concentration of suspended impurities in oil, %; Qpr specified productivity of centrifuge, cu.m/h; k, f, and d are empiric coefficients. EFFECT: enabled achieving required mechanical purification degrees owing to oil temperature control possibility. 1 dwg
