New multi-pollutant scrubber
The Singapore-based company Ecospec says its CSNOx scrubber is the first commercially viable solution capable of reducing carbon dioxide (CO2), sulphur dioxide (SO2), nitrogen oxide (NOx) and particulate matter (PM) emitted by ships within a single system. The US classification society American Bureau of Shipping (ABS) has witnessed the testing of the scrubber system at a shore-based test rig, verifying that the system was capable of removing more than 99 per cent of SO2, 50–80 per cent of NOx, and some 30–55 per cent of CO2. Starting this autumn, sea trials of the scrubber system onboard tankers will be witnessed and verified by ABS and the Maritime and Port Authority of Singapore as part of the IMO type approval process for an exhaust gas cleaning system.
