Sulfuric acid condenser

Efficient Cooling and Acid Condensation in WSA and SNOX™ Plants

The WSA condenser in WSA and SNOX™ plants cools the process gas with atmospheric air, typically from 280°C to 100°C. This first makes the SO3 in the process gas react with water vapor to form the sulfuric acid vapor, and secondly, the sulfuric acid vapor condenses to form the sulfuric acid liquid.

The WSA condenser consists of a steel casing containing a large number of vertical glass tubes. The acid is condensed on the inside of the glass tubes. The WSA condenser has acid proof brick-lining in the bottom section and a top section lined with a fluoropolymer.

WSA condensers are supplied only in connection with WSA or SNOX™ plant technology.

Sustainable Aviation Fuel

As a direct replacement for conventional fuel, SAF is an easy decarbonization measure that will help the aviation industry decarbonize immediately.

Power-to-X

To lower emissions in energy-intensive industries and long-distance transportation, we need technologies such as electrolysis in Power-to-X processes technology.

Renewable fuels

Renewable fuels will help us decarbonize heavy-duty transportation, and we’ll need proven technologies for their production. Luckily, these already exist.

Hydrogen

The abundance of hydrogen coupled with its potential for sustainable methods of production, positions it as a promising solution in the global energy transition. 

Ammonia

Ammonia is considered a gamechanger in decarbonizing the maritime industry and other energy-intensive industries where direct electrification is not an option.
