Dutch/​French duo to offer safer scrubber neutraliser

A new and safer alternative to sodium hydroxide for use as the alkaline source in closed-loop scrubbers has been developed by a partnership between Netherlands-based Nedmag and French organisation Timab Magnesium.

Sodium hydroxide which is most commonly used as the alkali source for closed-loop scrubbers is a hazardous product that can cause chemical burns if handled incorrectly. Nedmag and Timab have jointly developed an innovative magnesium hydroxide product called MH53S MARE with the objective of offering it to ship operators as the best alkali source for their scrubber operations. Magnesium hydroxide does not have the hazardous properties associated with sodium hydroxide and is commonly used by humans as an antacid and a laxative.

MH53S MARE is said to combine a very effective and safe alkali power with extremely high purity and best-in-class stability properties. After several years of successful use of MH53S MARE on board several vessels, the two partners are bringing this solution to the industry on a global scale. By combining their strengths, the two partners aim at improving further technical support as well as optimising global supply chains. In addition, production capacity at Nedmag was doubled in 2018, with an additional expansion planned to support the industry’s growing demand.

Alex Medendorp, Sales and Marketing director of Nedmag, is pleased with this new cooperation. “This approach fits very well in the vision of our company. We strongly believe in the added value of partnerships to gain the maximum benefit for our customers. With Timab Magnesium we have found the right partner to establish MH53S MARE as the reference in marine gas scrubbers.”

François Mazaré, Industrial & Environmental Applications Director with Timab Magnesium said, “Along with Nedmag, we are offering to the market a product with excellent performances, as well as a service tailor made to the maritime industry requirements. We are extremely proud to contribute to a solution for the SOx emission challenge faced by the maritime industry."
