Wärtsilä Launches New Smaller & Eco-efficient Scrubber Design

261

Wärtsilä has launched its new IQ Series exhaust gas treatment system, designed by its Exhaust Treatment business unit in Moss, Norway, says a press release published on their website.

About the IQ Series

Latest advancement

The IQ Series is the latest advancement in maritime exhaust gas treatment technologies, and it features several improvements that make the technology especially well-suited to container vessels, satisfying the increased demand in scrubbers as a compliance option from the container market segment.

Innovative design

The IQ Series scrubber uses an innovative design that allows the same exhaust gas cleaning results to be achieved within a smaller footprint. The scrubber takes up 25% less space, is 30% lighter, and has 35% less volume, which minimises the impact on a vessel’s cargo-carrying capacity, and therefore its profitability.

Power configuration

Additionally, the scrubber – which can be configured to use between 20 and 70 MW of power depending on vessel requirements – features the same modular design as Wärtsilä Exhaust Treatment’s other exhaust gas cleaning solutions.

Tackle pollutants

This means that the IQ Series can be upgraded with further technologies that enable other pollutants to be tackled within the stack, including exhaust gas recirculation (EGR) to cut NOx, a black carbon filter to cut particulate matter (PM), a depluming unit to cut visible steam from the stack, and even a carbon capture and storage (CCS) module that Wärtsilä is currently developing in its Moss test facility.

Design features

The new design features several improvements that make the technology especially well-suited to container vessels, satisfying the increased demand in scrubbers as a compliance option from the container market segment.

“We have particularly designed IQ Series with our container segment customers in mind. There is huge demand in the container market for exhaust gas cleaning solutions that enable compliance and have a minimal impact on the profitability of the vessel. That’s why we have brought to market this new design that is lighter, smaller and less voluminous,” Sigurd Jenssen, Director, Wärtsilä Exhaust Treatment, said.

Environmentally-friendly option

IQ Series is also a more environmentally-friendly option for owners and operators looking at the impact of their investment decisions, with Wärtsilä manufacturing the technology using 50% recycled steel.
