Sulfuric acid cooling System

Two-Step Acid Cooling System for WSA and SNOX™ Plants

The acid cooling system of WSA and SNOX™

The acid cooling system of WSA and SNOX™ plants performs a two-step cooling of the hot product sulfuric acid from the WSA condenser. First, the hot acid is quenched with cold acid, before going to a pump reservoir. Then the acid is pumped through the acid cooler, and from there the acid stream is split between quench acid and product acid going to the storage facilities.

All acid piping is internally protected with PTFE lining. The acid pumps are of the centrifugal type. The impellers are made of fluoropolymer and the casing of fluoropolymer-lined carbon steel. The acid cooler is a high-alloy plate heat exchanger.

Sulfuric acid cooling systems 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.
