REDUCING VISCOSITY BY ELEVATED TEMPERATURE-MEDIATED DECOMPOSITION OF NAPHTHENIC ACIDS IN HYDROCARBON CRUDE OILS Russian patent published in 2001 - IPC

Abstract RU 2167910 C2

FIELD: crude oil treatment. SUBSTANCE: heat treatment of crude oil with acid number higher than 2 mg KOH/g is conducted at 204 C in treatment zone for a period of time long enough to considerably reduce viscosity and simultaneously remove gaseous reaction products accumulated during one heat treatment cycle. EFFECT: facilitated viscosity reduction. 9 cl, 3 tbl, 3 ex
