Wärtsilä has introduced a new portfolio of services, Environmental Services, to both the marine and energy market. Environmental Services will help customers to minimize emissions into the air and water, and help them to meet increasingly stringent legislation and regulations. The new portfolio includes a range of products, solutions and services aimed at both land-based power plants and ship installations. As part of the portfolio, Wärtsilä offers catalysts (SCR) that treat nitrogen oxide (NOx) emissions, while scrubbers are offered for removing sulphur oxides (SOx). Both are harmful emissions that have detrimental effects on humans and nature. Wärtsilä can also offer complete oily water treatment systems for power plants and marine applications that meet the most stringent standards.
