New research at the Process Industrial Centre at Lund University, shows how to make the Polyethylene manufacturing more environmental friendly and increase their profit at the same time.


Polyethylene producers are facing a constantly changing market, creating a need to move between different levels of cost efficiency by manipulating the feeding of raw materials into the reactors. Per-Ola Larsson at the Process Industrial Centre at Lund University ( have studied this in an existing BorstarR polyethylene plant in Borealis AB producing bimodal polyethylene, but the method can be implemented for each continuous process that can be modeled. By optimizing the quality changes and reducing the amount of time that the process runs out of specification, the waste products decreases and the efficiency of the process greatly increases. The cost of each product is taken into account, thereby minimizing the loss of the more expensive product.
