JX Nippon unveils engineering design for polyisobutylene plant expansion in Japan


JX Nippon Oil & Energy has launched front-end engineering design for polyisobutylene (PIB) plant expansion at the company's site in Japan.

The transparent non-noxious high-viscosity liquid, PIB is used for sealing compounds of multi-layered glass and medical use adhesive.

JX Nippon said that the PIB business has been developed based on original technology since 1980 to add value to C4 fraction at Kawasaki.

The company's existing PIB plant has production capacity of 7,000tpa, compared with 35,000tpa of the liquid's global demand.

The demand is expected to increase in Asia and across the globe.

"The new PIB plant will have a capacity of 5,000tpa."

In response to rising demand for long-term supply sustainably, the company plans to proceed to the further detailed-feasibility study to construct the new PIB plant, which will have a capacity of 5,000tpa.

By improving quality, developing applications and reinforcing the stable supply structure, JX Nippon aims to advance the presence of its PIB business.

Construction on the new plant is set to begin between January and March 2018 with commercial operation expected in October 2019.

Polyisobutylene is composed of long-chain hydrocarbon formed by polymerisation of isobutene. It is stable under normal conditions and is a semi-solid polymer free of impurities.
