  Scrubber technology


Fuji Electric is  re-applying its core technologies and expertise from the land to the sea.
Through optimal integration of proprietary technology and other products and technologies, Fuji Electric has created a new value-added solution for ships.




Measurement and gas analytical technology - CEMS (Continuous Emission Monitoring System)

The technology behind Fuji Electric laser gas analyser for ships is a product of its experience in developing air pollution monitoring and measurement equipment for industrial plants.

fast and accurate analysislaser analyser for marine application

Fuji Electric’s laser gas analyser is capable of measuring and analysing both SO2 and CO2 in seconds. Its high-speed response time amounts to more precise, higher-resolution monitoring than conventional sampling analysers. The analyser determines in real time the state of exhaust gases after washing; thus, it optimizes the SOx scrubber’s pump operation based on alkali content in wash water.
This leads to improved fuel economy and reduced operating costs.

Fuji Electric’s laser gas analyser can be directly installed on the exhaust flue. Its high anti-dust performance guarantees stable analysis and facilitates low maintenance.

As part of the world’s smallest EGCS, Fuji Electric’s laser gas analyser is one-tenth the size of a conventional sampling analyser. Occupying less space gives it a major advantage over conventional sampling analysers and facilitates both retrofitting and installation in new ships.

Scrubber technology

Fuji Electric SOx scrubber for ships utilizes cleaning technologies and is the result of our extensive experience in fuel cell development and geothermal power generation.

► Sox scrubber

Fuji Electric’s SOx scrubber for ships is the very first in the world to use cyclone technology. Within the scrubber, a highly diffused spray of wash water increases contact between exhaust gases and liquid droplets, removing SOx by absorption. The cyclone method makes a mixing plate (which needs regular maintenance) unnecessary; so it also makes for lower maintenance costs.

World’s smallest SOx scrubber
Removes over 98% of SOx
By adopting cyclone technology, Fuji Electric’s SOx scrubber keeps pressure loss to less than 1kPa and has achieved significant downsizing. Its scrubber is 50% more compact than other SOx scrubbers on the market: it is lightweight, facilitating installation in ships. It can remove over 98% of sulphur in exhaust gases. Its operation can be optimized based on engine load, minimizing fuel consumption and impact on operating costs.

On-board testing of a SOx scrubber for a
main engine (MV Nadeshiko) (01:57)
In March 2016, Fuji Electric provided the exhaust gas cleaning system for a test. That involved the installation of an exhaust gas cleaning system (EGCS) for a main engine on an operating new-build vessel and a practical test of a
closed-loop mode. The test constituted a joint R&D effort that was supported and promoted by ClassNK and Imabari Shipbuilding Co., Ltd. It was the first time in Japan for a SOx scrubber to be installed on a bulk carrier.
