Polyolefin (PE/PP)

Summary

TOYO is an authorized bidding contractor for both the UNIPOL™ Polyethylene (PE) Process offered by Univation Technologies, LLC, and the UNIPOL Polypropylene (PP) Process offered by W. R. Grace & Co.-Conn..

Features

The UNIPOL Process is the first gas-phase process in the world to have succeeded to manufacturing PE in a variety of the range from LLDPE to HDPE. About 150 PE and PP production lines using gas-phase technology related to UNIPOL are serving the needs of the world’s polyolefin industry. UNIPOL is featured with a fluidized bed reactor to polymerize monomer (ethylene for PE and propylene for PP) in gas phase under a specific catalyst with a co-monomer and hydrogen. A solid particle bed is formed inside the reactor on which the polymer accumulates and is fluidized with the gas flow. There is no part mechanically moving nor a solid separation equipment like cyclone installed inside the fluidized bed reactor, This unique feature lowers construction cost and increases reliability of the production remarkably.

Experience

In 1989, TOYO was awarded the first UNIPOL PP plant in Indonesia. Since then TOYO has already delivered 24 PE plants and 8 PP plants in 12 countries over the world including one of the world largest PE plant of 800,000 kTA in Saudi Arabia.
