The freezing point of waxy crude oil is greater than 30 ℃, and it is easy to condense wax during normal temperature pipeline transportation, resulting in difficulty or even loss of fluidity of crude oil, which greatly affects the crude oil transportation. This product can change the growing process of wax crystals, disperse wax crystals and prevent wax from forming network structure, so as to reduce the freezing point and viscosity of crude oil and improve the flow performance of crude oil. It has strong adaptability to different types of crude oil, can realize normal temperature transportation, effectively reduce energy consumption of crude oil transportation.
