Fuel gas supply systems | Reducing pollutant emissions in the shipping industry: Clean alternative fuel liquid ammonia requires fail-safe and hermetically tight pumps
In total, around 11 billion tons of freight were transported by sea worldwide in 2021 – which corresponds to almost 90 percent of all trade goods. Producing more than 1 million tons of greenhouse gases, the shipping industry causes around 3 percent of global carbon dioxide emissions per year. And there are other pollutants, such as sulfur oxides, nitrogen oxides, volatile organic compounds and[more]
Hermetically tight 170 °C high-temperature pumps for production
In the existing chemical installation in a Wacker Chemie plant, the safety-related design of the relevant pump systems had to be thoroughly renovated. The requirements were extremely strict: Operating temperatures are normally around +170 °C, and can rise to a maximum of +200 °C. During the winter months, moreover, the ambient conditions are specified as very cold under some circumstances. Lewa[more]
