Brief Description

Description :

Majority of the Indian crude oils have high wax content. Crystallization of wax during transportation through long distances may result in reduced pumping rates, wax deposition in pipelines and storage tanks and restart problems in case of shutdown in the pipeline. High waxy crude oils are treated with additives commonly referred to as Flow Improvers, wax modifiers and Pour Point Depressants before they are transported to overcome these problems. Flow improvers reduce the pour point, viscosity, and yield value and help in easy restart in case of shut down in the pipeline. Flow improvers tend to be specific to crude oils in view of the differences in chemical compositions. NEIST has developed a wide range of flow improvers to suit the Indian crude oils.
