Demineralised Water Unit at ZapSibNeftekhim Ready for Commissioning

ZapSibNeftekhim has prepared its demineralised water unit for commissioning. It is a two-stage reverse osmosis and electric deionisation plant with a total capacity of 244 cu m per hour.

“A similar plant is in use at our operating production facility SIBUR Tobolsk,” commented Andrey Kolyshnitsyn, Head of Commissioning at ZapSibNeftekhim’s Pyrolysis. “It is designed to treat and fully demineralise process water. In its turn, treated water will be used to feed pyrolysis and butadiene production facilities.”

Demineralised water serves as boiler feedwater to generate steam in low and high pressure boilers, fill turbine condensers and other systems in pyrolysis furnaces, and wash feedstock for the methyl tertiary butyl ether (MTBE) production. The technology was developed by EnviroChemie.
