Nobian has opened a fully electrified salt-production facility in Mariager, Denmark. Using mechanical vapor recompression (MVR), the plant replaces gas-based steam with electricity by compressing and reusing process steam, improving energy efficiency and increasing site capacity by about 60%. The MVR installation has been operational since January 2026.

What opportunities and challenges do you see in scaling MVR-based electrification to other chemical processes or sites?

Nobian (Utrecht, the Netherlands) has officially opened a new fully electrified salt production facility in Mariager, Denmark. Based on mechanical vapor recompression (MVR) technology, the installation enables more energy-efficient production while increasing site capacity by approximately 60%.  Operational since January 2026, the MVR installation replaces gas-based steam with electricity by compressing and reusing process steam […]

MVR only delivers that 60% bump if you stay ahead of scaling and keep the compressor out of surge; otherwise it’s alarm city. What’s their anti-surge and grid-dip ride-through strategy on the VFDs (controls UPS, DC bus choppers, flywheel) and how often are they CIP’ing the brine side to keep carryover from chewing up the impeller?

MVR can be a win, but only if you keep the evaporators clean and carryover near zero - what’s their brine pretreatment and demister strategy to prevent compressor erosion and fouling? Also, how are they handling grid dips and demand charges at that scale - VFD ride‑through/flywheels and thermal storage, or is there a gas-steam backup for peak or outage events?
