Pour point depressing and viscosity reducing solid paraffin inhibitor

Номер: CN103450864A
Автор: Zhang Mingxia, Yang Quanan, He Zhiwu, Yang Huili, Liu Aihua, Zhou Pei
Принадлежит:

The invention relates to a pour point depressing and viscosity reducing solid paraffin inhibitor, which comprises: 15-20% of a compound of an amphoteric surfactant and a nonionic surfactant, 34-42.5% of solid polyethylene, and 37.5-51% of a pour point depressant. The amphoteric surfactant is hexadecyl dimethyl sulfopropyl betaine, the nonionic surfactant is polyoxyethylene cetyl alcohol ether compound, and they are in a molar ratio of 5:1. The pour point depressant is a compound of polyethylene-vinyl acetate copolymer and fumaric acid-vinyl acetate copolymer in a mass ratio of 3:1. Being able to reduce the high wax content crude oil viscosity by over 80% and lower the crude oil pour point by 11DEG C, the solid paraffin inhibitor provided in the invention has good high temperature resistance, and avoids the influence of thermal washing on paraffin inhibiting effects. At a concentration of 200mg/l, the paraffin inhibiting rate can reach 75%-80%, and the use time of the paraffin inhibitor ...
