DNV GL has awarded the Chinese scrubber manufacturer Shanghai Bluesoul Environmental Technology with an Approval in Principle (AiP) in recognition of the technical feasibility of the BlueSulf scrubber system.
The AiP is the first of its kind for a scrubber according to the new DNV GL rule set, and the first for a Chinese scrubber manufacturer. DNV GL will also provide advisory services to Bluesoul, including hardware-in-the-loop testing, simulations using the DNV GL Cosmoss tool and analyses using computational fluid dynamics (CFD).
Bluesulf Scrubber
Shanghai Bluesoul’s Bluesulf scrubber is a hybrid system that can switch between open and closed loop mode. This type of system is the most popular at present, as it allows greater flexibility to adjust to changes in water salinity and requirements in different ports. In some areas the use of open loop scrubbers has been prohibited.
Able to operate both on seawater and fresh water, the design reduces the sulphur content in exhaust gas to 0.1 per cent or less, ensuring compliance with the requirements of the Chinese Emission Control Area (0.5 per cent) that has been in force in eleven ports in China since 1 January 2017 and the upcoming global sulphur cap. The Bluesulf scrubber uses the sodium alkali method to clean exhaust gases.
