Pour point depressants are mainly used to reduce the pouring point of crude oil during crude oil extraction, gathering, transportation, storage, etc., so that crude oil can flow at low temperatures, reduce energy consumption, and thereby reduce costs. At present, the unit has dozens of pour point depressant products, covering four categories: maleic anhydride copolymer, poly(meth)acrylate, EVA modified, and nitrogen-containing polymer pour point depressants. Our company's products are oil-soluble polymers with long alkane main chains and polar side chains. When a small amount is added, they can greatly change the crystallization state of paraffin in the oil and change the interface state and rheological properties of the system. It reduces the pouring point of crude oil and can also reduce viscosity to improve the quality and efficiency of crude oil in mining, gathering, transportation, storage and other operations. It is mainly used to reduce the pour point of high waxy crude oil and is widely used abroad. Remarkable results have been achieved.
