Engine manufacturer in deal with German-based Couple Systems
MAN Diesel & Turbo has signed a cooperation agreement which will see it incorporating German-based Couple Systems’ a dry scrubbing system DryEGCS into power plant packages.
According to a statement, extensive field tests have already proven DryEGCS’ worth and the dry-scrubbing system was certified by German classification society, Germanischer Lloyd, in April of this year.
“The cooperation agreement aims to jointly develop customer solutions for dry scrubbing technology and to expand its application as far as possible,” says Dirk Thum, MAN Diesel & Turbo, Head of Marine Engineering Medium-Speed, Emission and Gas.
Dr Thum adds: “As a system supplier, MAN Diesel & Turbo will offer integrated solutions to its customers for engines and exhaust-gas cleaning systems featuring a scrubber and SCR catalyst for NOx reduction. This enables ships to operate economically on HFO and simultaneously comply with even the most stringent emission regulations.”
MAN says that, while current scrubbing systems mostly work on a wet base that has some inherent drawbacks, dry scrubbers represent a simpler solution that removes up to 99% of SOx from exhaust gas by means of a reactor filled with granulate of calcium hydroxide.
It adds that dry scrubbers have the following advantages over wet scrubbers:
no significant lowering of exhaust-gas temperature enabling an SCR located downstream to reach its operating temperature. NOx and SOx can thus be removed in one exhaust-gas cleaning system
negligible energy consumption
an easily handled and recyclable granulate
no transmission of pollutants into the sea during use
