About us

For the development of Scrubbers for maritime applications, we rely on the proven wet process which we have successfully implemented many times onshore: due to its compact design and as seawater is used, this washing procedure is both particularly space-saving and energy-efficient. The strict regulations of MARPOL-Annex VI are fully observed by the Scrubber-system of Babcock Noell.
Our Scrubber systems are generally applied as hybrid systems on vessels: the hybrid systems combine Open- and Closed-Loop operation within one scrubber unit. Our customers benefit from the opportunity to switch between both operation modes, depending on shipping routes and the corresponding statutory regulations. Of course it is possible to install only a Closed- or an Open-Loop Scrubber. The system concepts of Babcock Noell also allow flexibility during execution.
Our experts are pleased to advise and provide you with an individual profitability calculation tailored to your particular requirements and needs. Free of charge and without any obligations. Convince yourself of the benefits!

One System – Two Options
Hybrid Scrubber Concept with many Advantages:
The Scrubber is generally applied as hybrid system on the vessel: it combines Open- and Closed-Loop operation within one scrubber unit. Our customers benefit from the opportunity to switch between both operation modes, depending on shipping routes and the corresponding statutory regulations.
Open Loop Scrubber - Simple and robust
During Open-Loop operation, sulfur-containing exhaust gases are cleaned by the natural alkalinity of the seawater in a continuous process. The process water is discharged into the sea according to IMO-regulations.
Closed Loop Scrubber - Flexible and future-orientated
During Closed-Loop operation, the Scrubber operates as a closed circulation process by supplying an additive for chemical (SO2) separation to the wash water. As with the Open-Loop operation, the process water can be discharged or stored in a tank. In this way, waste water release in specially protected areas can be entirely avoided.

Bilfinger solution for desulfurization of ship engines certified 

Full steam ahead for maritime flue gas desulfurization: After only around three months of operation, the reference project on board the ocean tanker M/T Aurelia was awarded the International Air Pollution Prevention Certificate by certification company DNV GK on behalf for the German flag. At the end of last year, the ship was fitted out with a new flue gas desulfurization system supplied by Babcock Noell. This technology uses an absorption process to remove the sulfurous flue gases emitted by the ship. In this way, the ocean tanker meets the latest environmental standards. “More and more companies are interested in environmental technologies and this now also includes shipping companies. We have decades of experience in industrial plants which we are now putting to good use in ocean shipping. Bilfinger stands for top efficiency, reliability and environmental technologies made in Germany,” says Bilfinger CEO Tom Blades.
Bilfinger’s maritime desulphurization system provides ship owners with a solution at just the right point in time. In autumn 2016, the International Maritime Organization (IMO) adopted a resolution to broaden the rules for maritime environmental safety. Commitment to clean shipping
“The IMO’s decision is forcing us ship owners to either use expensive low-sulfur fuel or to install scrubbers on board to filter out the sulfur,” explains Lars Bremer, managing director of Carl Büttner Shipmanagement GmbH, the subsidiary responsible for ship operations. In summer 2016, the shipping company launched a pilot project to assess the technological potential of efficient desulfurization on the high seas in a practical trial. To this end, ocean tanker M/T Aurelia was fitted out with a desulfurization system. Sources of sulfur such as the main engine, the auxiliary diesel and the boiler were connected to the system and operated under varying conditions. The scrubber supplied by Babcock Noell is a hybrid system that operates in different modes. With the system placed in operation without any major incidents, the technology went on to prove itself in the three-month test phase. Andreas Breeger, head of maritime flue gas cleaning systems, Environmental Technologies at Babcock Noell, explains: “Acceptance testing by DNV GL was completed the first time and free of any reservations. As a result, this project milestone was reached within a very short space of time. For this reason, we are confident of being able to drive forward the technology changeover towards low-sulfur ocean shipping.”In particular, the enormous economic efficiency of scrubber systems looks set to generate strong market demand. Payback times are between one and two-and-a-half years.
