Marine Scrubber Systems: An Overview of Technology, Manufacturers, and Hybrid Systems

Marine scrubber technology has become increasingly popular in recent years due to the increasing stringency of emissions regulations for marine vessels. A marine scrubber is a system that removes pollutants, such as sulfur dioxide (SO2) and nitrogen oxide (NOx), from exhaust gases emitted by marine engines. Scrubbers are an alternative to using low-sulfur fuel, which is more expensive and can lead to engine performance issues.

Marine scrubber systems can be classified into two types: wet scrubbers and dry scrubbers. Wet scrubbers are more commonly used and work by spraying seawater or freshwater onto the exhaust gas, which reacts with the pollutants and removes them from the gas. Dry scrubbers use a solid material, such as lime or activated carbon, to absorb the pollutants from the gas.

The global marine scrubber market is expected to witness significant growth in the coming years due to the increasing demand for eco-friendly and cost-effective marine engines. The market is dominated by major players, including Alfa Laval, Wärtsilä, Mitsubishi Heavy Industries.

One of the latest trends in marine scrubber technology is the development of hybrid scrubber systems. These systems combine both wet and dry scrubbing technologies to optimize their efficiency and reduce operating costs. Hybrid scrubber systems can operate in both open and closed loop modes, allowing vessels to comply with emissions regulations in different regions of the world.

In open loop mode, the scrubber uses seawater to remove pollutants from the exhaust gas, which is then discharged into the sea. In closed loop mode, the scrubber uses freshwater and a neutralizing agent, such as sodium hydroxide, to remove pollutants from the exhaust gas. The resulting wastewater is then treated before being discharged into the sea.

One of the benefits of hybrid scrubber systems is that they are able to operate in open loop mode in areas with low alkalinity, where the use of seawater could cause corrosion issues. In addition, hybrid scrubber systems can reduce the consumption of neutralizing agents and freshwater, resulting in lower operating costs.

Several manufacturers are now offering hybrid scrubber systems, including Wärtsilä, and Alfa Laval.

Wärtsilä offers a hybrid scrubber system that uses seawater in open loop mode and freshwater in closed loop mode. The system also includes a water treatment plant to treat the wastewater before discharge.

Alfa Laval offers a hybrid-ready scrubber system that can be easily upgraded to a hybrid system. The system uses seawater in open loop mode and freshwater in closed loop mode, and includes a water treatment plant for the wastewater.

In conclusion, marine scrubber systems have become increasingly popular in recent years due to the increasing stringency of emissions regulations for marine vessels. Wet scrubbers are more commonly used, but dry scrubbers are also available. Hybrid scrubber systems are the latest trend in marine scrubber technology, offering the benefits of both wet and dry scrubbing technologies. Several manufacturers are now offering hybrid scrubber systems, including Wärtsilä, and Alfa Laval. With the continued focus on reducing emissions from marine vessels, the demand for marine scrubber systems is expected to continue to grow in the coming years.
