DESCRIPTION:

The product is a oil soluble viscous liquid containing polyester polymer, heavy aromatic solvents and surfactants.

​

FEATURES:

-The PPD lowers wax deposition rate and increase wax appearance temperature (WAT) and wax content of the deposits.
- The contents of asphaltenes and resins entrained in wax deposits get lowered when PPD was added into the crude oil.
- The PPD would weaken the mechanical strength of wax deposits, thus the wax resistive force decreases and therefore the risk of pig stalling accordingly gets lowered.
