PKN Orlen completes significant revamp project to double ethylene and propylene capacities

| By Mary Bailey

PKN Orlen (Płock, Poland) has completed the Olefin II revamping project, an investment which has allowed the company to double its ethylene and propylene streams – key feedstocks for the production of plastics. The modernized plants are capable of producing up to 700,000 metric tons per year (m.t./yr) of ethylene and up to 385,000 m.t./yr of propylene. The bulk of the output will be streamed to the new plants of Basell Orlen Polyolefins and Anwil Wloclawek.

In addition to increased production volume, the revamped Olefin II plant will play a fundamental role in capturing synergies with the refinery through enabling even better flexibility in consuming petrol and diesel.

“The enhancement of the petrochemical segment strengthens the economic position of PKN ORLEN, both in Poland and the region. Together with the petrochemical operations of Unipetrol, we have a chance to play a significant role in the European sector,” said Igor Chalupec, President & CEO of PKN ORLEN.

Current demand has appeared to be even larger than was forecast, and the doubled olefin volume has already been 100% allocated to customers. The bulk of production will be directed to the new production complex of Basell Orlen Polyolefins. The second biggest off-taker will be Anwil Wloclawek, which two years ago completed its own revamping of its PVC production facilities. The remaining volumes will be consumed by external customers.

The Olefin II plant is a key facility of the petrochemical complex in Plock. It was constructed in 1977-1980 based on Lummus technology. Initially, the plant capacity equaled 300,000 m.t./yr of ethylene and 125,000 m.t./yr of propylene. Between 1994-1995, the plant was revamped and annual volumes increased to 360,000 m.t./yr of ethylene and 135,000 m.t./yr of propylene. At the same time, plant energy consumption decreased by around 25%. The revamping of the Olefin II plant has marked the end of the Olefin I plant, which was constructed in 1971.

The latest investment translates into increased annual ethylene volumes, from 360,000 to 700,000 m.t./yr, and propylene from 135,000 to 380,000 m.t./yr. Taking into account the propylene streams from the catalytic cracker, PKN ORLEN is capable of producing 485,000 m.t./yr of propylene.

“In order to properly capture the significant domestic growth potential in olefin consumption, we are considering the construction of an Olefin III plant. This would be an efficient way of utilizing the larger petrol volumes of that are expected, due to the forecast increase in demand for diesel,” said Czeslaw Bugaj, Deputy CEO, Chief Operation Officer.
