Pour point depressants are mainly used to reduce the freezing point of crude oil during the process of extraction, gathering and transportation, storage, etc., so that the crude oil can flow at lower temperatures, reducing energy consumption and costs. At present, DESHI GROUP owns dozens of pour point depressants, covering four categories of maleic anhydride copolymers, poly(meth)acrylates, EVA modifified, and nitrogen-containing polymer. Our company’s product is an oil-soluble polymer with a long alkane parent chain and polar side chains. It can greatly alterthe crystalline state of paraffin wax in the crude and change the interface state and rheological properties of the system at a low dosing rate. Lowering the pour point of crude oil, and at the same time, it can also reduce the viscosity, and improve the quality and production efficiency of the crude. It is mainly used for pour point depressing of high wax content crude and is widely used abroad with remarkable results
