摘要：NOVELTY - A crude oil depressing method involves utilizing a supercritical methanol to intervene in a thermal cracking system of the crude oil to transfer the thermal cracking crude oil from the oil phase to the homogeneous structure, followed by cracking crude oil by the reaction kinetics control, which accelerates the alkylation of 18-30C mixed alkanes in crude oil at low temperatures, suppresses the condensation reaction in thermal cracking, and achieves a permanent reduction in the solidifying point of crude oil. USE - Method for depressing crude oil. ADVANTAGE - The method enables permanently reducing the condensation of the crude oil, and saving cost of crude oil pipeline transportation and subsequent processing. DETAILED DESCRIPTION - A crude oil depressing method involves utilizing a supercritical methanol to intervene in a thermal cracking system of the crude oil to transfer the thermal cracking of the crude oil from the oil phase to the homogeneous structure, where thermodynamic parameters of the supercritical methanol include temperature of 370-400 degrees C, density of 0.25-0.30 g/cm3, followed by cracking crude oil by the reaction kinetics control, which accelerates the alkylation of 18-30C mixed alkanes in crude oil at low temperatures, suppresses the condensation reaction in thermal cracking, and achieves a permanent reduction in the solidifying point of crude oil. An INDEPENDENT CLAIM is also included for a crude oil.
