Gas scrubbing
About
Integrated scrubbing process embedded in the plant to maximise the gas cleaning efficiency
Gases from phosphoric acid production must be scrubbed to prevent the release of fluorine, dust and other chemicals in the atmosphere.
The equipment fitting perfectly Prayon scrubbing process is the gas scrubber provided by Profile.
Sustainability & responsible water management
Gas Scrubbing
As part of a fully integrated phosphoric acid production plant, the Prayon gas scrubbing process uses several cross-flow water sprayers to remove these chemicals from the gas. The water bleed from the gas scrubber can therefore be entirely used in the plant, usually ending up as cake washing water at the filtration section.
As a result, the Prayon gas scrubbing system ensures a sustainable use of water as the full quantity of water is recycled in the process.
