Scientists in Singapore have designed a sulphur scrubber to help reduce emissions

Scientists in Singapore have developed a revolutionary emissions abatement system that removes pollutants from exhaust gas to help the international shipping industry meet ambitious emissions targets.

In 2013, the International Maritime Organisation (IMO) introduced new regulations to reduce exhaust emissions attributed to the shipping industry. Shipping is responsible for around 90% of global trade and produces around 900 million tons of greenhouse gas emissions yearly.

Researchers from the Agency for Science, Technology and Research Institute of High Performance Computing (IHPC) together with Sembcorp Marine Ltd and Ecospec Technology Pte Ltd are finding ways to meet the IMO's new emissions targets.

The team from Sembcorp Marine and Ecospec Technology has developed an exhaust gas treatment system, called cSOx, which removes SOx and CO2 from ships' diesel engine and boiler exhaust emissions. It uses ultra-low-frequency electromagnetic waves to treat seawater, thereby optimising the system's ability to absorb sulphur dioxide and CO2.

In early 2015, a memorandum of understanding was signed by IHPC, Sembcorp Marine and the University of Glasgow to collaborate to make ships more eco-friendly. Plans include designing vessels with improved hydrodynamics for better fuel efficiency and further enhancing the exhaust gas cleaning and ballast water treatment systems developed by Sembcorp Marine and Ecospec Technology.

In the future the team plans to utilise the IHPC computational fluid dynamics model to evaluate the scaled-up cSOx exhaust gas cleaning system's geometric parameters for better performance.
