TOKYO (ICIS)--Japanese chemical producer Sumitomo Chemical has decided to permanently close its 95,000 tonne/year caprolactam plant in Ehime prefecture at the end of 2015 due to its old age, the company said in a statement on Monday.

The unit, which uses the liquid phase method of production, came on stream in 1965, according to Sumitomo Chemical.

After almost 50 years, the facility has lost its competitive edge due to the high cost of maintenance and repairs, the company said.

Sumitomo Chemical’s one other caprolactam unit – with a capacity of 85,000 tonnes/year, which came on line in June 2003 – will continue its operation, the company said.

The 85,000 tonne/year plant employs the gas phase method, which is a shortened production process, and costs less than the liquid phase method, according to Sumitomo Chemical’s website.
