1. Description

AD-502 is a mixture of polymers, which can significantly decrease condensation and viscosity of crude oil with 10-30% paraffin content by absorbing the paraffin crystal. When added in the pipelines, it may help lower the inlet and parallel operation temperature, save power consumption, slow the pipeline corrosion, extend its service life and lower the minimum transmission load to ensure safer and more flexible low and ultra-low load operation. It is applied to long pipelines and oilfield internal pipelines for depressing and viscosity reduction during crude oil production and transportation, and brings high economic and social benefits.
