Finnish scrubber specialist and engine manufacturer MAN Diesel & Turbo enhance cooperation for using water treatment systems with EGR processes.
Langh Tech is primarily known for its portfolio for exhaust gas cleaning. Now the company got approval from MAN for another product[ds_preview]. The companies have been working in close cooperation to develop a water treatment system to be used for cleaning the process water of Exhaust Gas Recirculation (EGR) systems.
EGR is a method to reduce NOx emissions to meet Tier III requirements. According to Langh, in the EGR process, approximately one third of the exhaust gas is recycled back into the engine, first removing the particles from the redirected gases with a small scrubber. »The process water from exhaust gas washing is continuously cleaned during EGR operation and this is where Langh Tech’s water treatment technology is applied«, the Finnish supplier announced now. Langh Tech water treatment is based on membrane filtration, meaning that the operational costs are kept low and the waste consists only of small amounts of compact dry sludge.
The first test runs of the system were performed in December 2015 at MAN‘s testing facility in Copenhagen, using a small-scale prototype built into a container. »The results were good, leading to continued and deepened cooperation between the companies«, it was added. The process has been fine-tuned over time, and now MAN has granted approval for the Langh Tech water treatment system to be used in combination with the EGR process. The approval process includes a long-term testing period in cooperation with MAN.
