Alfa Laval Announces Inline Scrubber Design

Alfa Laval says the lauch of its inline I-design scrubber makes the PureSOx platform "even more versatile."

Alfa Laval Monday announced the launch of its inline I-design scrubber, saying that the addition makes its PureSOx platform "even more versatile" by providing another alternative for vessels with more complex structural needs, including certain RoPax and cruise vessels.

"Through open-loop, closed-loop and hybrid arrangements, PureSOx can be suited to any vessel's sailing profile," said René Diks, Manager Marketing & Sales, Exhaust Gas Cleaning for Alfa Laval.

"By adding an inline scrubber design to the already flexible PureSOx platform, we've made PureSOx even easier to adapt to individual vessel constructions."

Diks adds that, although inline configurations should not be used as a default, they do enable easier accommodation of certain challenges of some vessels.

Alfa Laval explains that great consideration was given to the water trap during the design process of the inline scrubber, as it is not formed naturally as is the case with a U-design.

“Because the absorber section is located atop the jet section in the I-design, no water trap is created between the two,” says Diks.

"A key focus was eliminating the potential for water backflow, which is done by means of an internal water trap combined with overboard arrangements."

Alfa Laval says that the I-design scrubber can be configured with multiple inlets, a feature that is said to reduce both space requirements and installation costs as just one scrubber is needed to treat exhaust gas from multiple sources.

The inline scrubber is said to also provide a reflux option for vessels that carry passengers, a feature that "reduces the risk of dirty water droplets discolouring the ship’s deck."

In May, Alfa Laval announced that it had patented its scrubber wash water cleaning technology, which is featured in the company's PureSOx marine scrubber system.
