Abstract

Summary. A scrubber with one or more tray levels, provided with rocker valve cassettes, has in pilot tests been proved excellent to clean marine diesel engine exhaust gases from sulfur oxides and nitrogen oxides, since the back pressure is low and by the invention can be kept constant and within permitted limits, and this over the entire engine RPM - and power-rating register, because these engines are particularly sensitive to high back pressures. The invention can also be applied in similar demanding industrial processes such being sensitive for variations in backpressure or having requirements for 100% SOx purification and/ or NOx purification > 8%.In testing, performed with diesel fuel with increased sulfur content, a 100% efficient sulfur oxide purification has been confirmed as well as a simultaneous NOx purification up to 25% and it was also verified that the exhaust gases can be introduced directly into the scrubber, without clogging problems due to the soot in the exhaust. Further advantages are obtained by that a scrubber of the invention operates at high sulfite content, up to at least 200 g /L, wherein less chemicals and fresh water is spent, whilst the space for holding tanks is reduced.The applications are mainly in the marine sector.
