30NOV2018 - NEWS - Singapore to ban the use of open loop scrubbers in its waters

Singapore which is one of the busiest port cities in the world, is to ban the use of open-loop scrubbers in its waters. The decision to ban open-loop scrubbers had been made to protect the local marine environment. An open-loop scrubber uses seawater as the medium for cleaning or scrubbing the exhaust. Seawater is normally supplied by a dedicated pump. CO2 dissolves in seawater forming carbonic acid, bicarbonate or carbonate ions depending on the pH. In a closed loop-type scrubber, meanwhile, treated water is circulated through the scrubber to keep the scrubbing process independent of the chemistry of the waters through which the vessel is sailing. Open-loop scrubbers are currently banned in Belgium, California, Massachusetts and along Germany’s Rhine river with other countries understood to be looking at banning the technology.
