DryEGCS^® removes virtually all of the sulphur dioxides contained in the exhaust gas, and turns it into a valuable resource or removes it from the biosphere. The single residue produced can be disposed of in the power plant industry or as mine filling together with the fuel residues. If it is utilised in a power plant, the sulphur is generally converted into recyclable gypsum.  As a result, 75% of the sulphur oxide released in the operation of the ship’s engines does not reach the critical environmental regions of the atmosphere, hydrosphere and the high lithosphere. Particles in the diesel engine exhaust gas, in particular micro-particles, are largely removed by DryEGCS^®. The power requirement for operation of the plant is negligible at 0.006 kW per kW of engine power.

The exhaust gas temperature after the desulphurisation system is well above the dew-point temperature. Therefore the exhaust gas need not be heated up. The catalytic converter for reduction of the nitrogen oxide can be installed directly behind the exhaust gas desulphurisation unit. No energy-consuming re-heating is necessary for this and a smaller catalytic converter can be installed that has a longer life-cycle expectation.
