Long-chain hydrocarbon polymers included in Crude Oil Flow Improvers serve as flow turbulence inhibitors along pipeline walls, helping to lessen the energy lost in turbulent activity. In some situations, when the storage facility or pipeline carrying crude oil is closed for an extended period of time, the cooled crude oil gradually develops a gel structure, leading to high yield stress. Improvers for the flow of crude oil aid in restarting the pipeline.
Two important aspects to take into account when preserving the uniform flow of crude oil are the continual variations in viscosity and drag coefficient. The goal of smooth-flowing crude is achieved/maintained with the use of Crude Oil Flow Improvers by keeping these parameters constant at a level that requires less energy and capital. The API gravity of heavy/sour crude, which contains a significant proportion of sulfur, is greater than 20, indicating low turbulence.
