Replacement of brine preheaters

Delfzijl, 2023

Impact on steam consumption

Nobian has replaced two brine preheaters at its Delfzijl plant. These preheaters have a significant impact on steam consumption in the salt production process. They were commissioned in the first half of 2023 and have been in operation since, resulting in savings of about 35,000 tons of steam per year. This translates to an annual saving of more than 5 kton of CO₂.

Increased durability

The old preheaters were at the end of their service lives and their energy efficiency was significantly reduced due to their age. As part of the replacement project, we investigated how to increase the durability of the new preheaters. We opted for titanium as a more durable material, with an expectation of a significant increase in operational life.
