A corrected story follows.

PRAGUE (ICIS)--Poland's PCC Rokita has completed the first stage of a project to eliminate mercury from its chlorine production, the company said on Friday.

Two of four planned membrane electrolysers have been installed at its chlorine plant in Brzeg Dolny, southwest Poland, it added.

The company intended in the near term to entirely convert its mercury-based electrolysis to the more advanced and environmentally sound membrane-based electrolysis, it said.

In the meantime, following the first stage of the conversion, it would run a combined electrolysis plant.

"In this combined electrolysis plant the emission of mercury-containing wastewater from the existing electrolysis plant can be completely avoided thanks to recycling.

"In a second stage, PCC Rokita will add two additional membrane electrolysers and will build a caustic soda concentration unit. After that the mercury plant will be disassembled,“ said Susanne Biskamp, a spokeswoman for PCC Rokita's German parent company, PCC.

PCC Rokita uses chlorine in the production of propylene oxide (PO) for the manufacture of polyols.

The new membrane-based technology complied with the European Integrated Pollution Prevention Control (IPPC) Directive and the Best Available Technology (BAT) international standard, the company said.

PCC Rokita has a nameplate capacity of approximately 25,000 tonnes/year for PO and a maximum capacity of around 70,000 tonnes/year for polyols at Brzeg Dolny.
