Valmet Corporation's trade press release 2 May 2022 at 3:00 PMValmet launches new Valmet Wet Electrostatic Precipitator (WESP) to help the marine industry improve its emission control.The solution goes beyond the International Maritime Organisation's 2020 regulation on sulfur emissions from ships, as it can clean up harmful particulate emissions from a ship's exhaust gases.“For years, we have been developing technologies to help the marine industry reduce its emissions.The new wet electrostatic precipitator helps our customers effectively reduce particulate emissions from their ships, ”says Timo Lamminen, Product Sales Manager at Valmet.Years ago, Valmet was the first to launch an open and closed loop hybrid sulfur scrubber and unveiled the most efficient sulfur scrubber water treatment system on the market in 2021. WESP is a direct continuation of this development path to bring solutions to more environmentally sustainable marine transportation.Valmet's wet electrostatic precipitator is used to reduce particulate emissions such as black carbon.The equipment can also remove heavy metals, acids, small oil droplets and visible water vapor from the exhaust stream.The operation is based on a very high electrical charge between the electrodes and the collection tubes.The electric field charges the particles in the exhaust stream and causes them to accumulate on the surface of the collection pipes.The process is automatically controlled by Valmet DNA or some other automation system and can be integrated with Valmet's Industrial Internet (VII) functions.Valmet has developed a WESP system suitable for ships together with its partner AWS.The combination of a wet electrostatic precipitator and a sulfur scrubber reduces exhaust emissionsValmet has tested a combination of a wet electrostatic precipitator and a sulfur scrubber that has been able to reduce particulate and black carbon emissions from marine diesel engines by up to 99 percent.The solution will help shipping companies reduce those emissions and thus combat global warming.The system will make it possible to stay within the limits of stricter emission regulations and even achieve the EURO 6 standard, which is the strictest emission limit for road transport in the European Union.The pilot test was organized together with VTT.At present, the IMO regulations on emissions to air focus mainly on emissions of sulfur oxides and nitrogen oxides (SOx and NOx).However, awareness of the harmful effects of particulate matter and black carbon emissions on global warming and human health is growing.Sulfur scrubbers can only remove particles and black carbon from the exhaust stream up to a certain, fairly low limit, while a combination of a sulfur scrubber and a wet electrostatic precipitator or an independent wet electrostatic precipitator can remove these harmful particles from a ship's exhaust almost completely.With the new Valmet Wet Electrostatic Precipitator, ships can effectively reduce harmful particulate emissions, making the air cleaner.Further information: Anssi Mäkelä, Sales and Technology Manager, Valmet, anssi.makela@valmet.com, tel. +358 50 317 4173 Timo Lamminen, Product Sales Manager, Valmet, timo.lamminen@valmet.com, tel. +358 40 868 3628 Valmet's solutions for the marine industry )Valmet is the world's leading supplier and developer of process technology, automation solutions and services to the pulp, paper and energy industries.With our automation systems and flow control solutions, we serve an even wider customer base in the process industry.Our goal is to become the best in the world in serving our customers.Our 17,000 professionals work close to our customers, committed to driving our customers to success - every day.The company has more than 220 years of industrial history and strong evidence of continuous improvement and renewal.In 2022, the company reached a significant milestone when the flow control company Neles merged with Valmet.The combined turnover of the merged companies in 2021 was approximately EUR 4.5 billion.Valmet's shares are listed on Nasdaq Helsinki and the company is headquartered in Espoo.Follow us on valmet.fi |Twitter |Twitter (IR)LinkedIn |Facebook |YouTube |Instagram |Instagram (IR)Processing of personal data
