CONTUFILT-MH
Hot Gas Filtration
Separating solids in hot corrosive environments
Gas reactions are carried out in the presence of precious metal catalysts. Processes generate particles and the gases which are vented carry solids with them. These solids have to be recovered. CONTUFILT-MH metallic filters avoid poisoning of catalysts or recovery of products from the off-gas.
Hot gas filtration in chemical processes is of prime importance to keep the contaminants away. One such example out of many is Nitric Acid. The production of Nitric Acid requires an NH3/ Air mixture to be filtered to protect the expensive catalyst beds which are the oxidation zones in the reactor. The filtration is very critical as it helps reduce downtimes and safeguards the expensive noble metal catalysts. Other industries also use hot gas filtration down to micron levels. We will work closely with you to find a cost-effective and reliable solution.
Process Operation
The system comprises filter candles made up of our Vacuum fused Metallic open channel proprietary media, suitable for fine particle retention
Candles are placed on a tube bundle in a housing. We perform specific filtration functions, back pulsing and gas-assisted discharge of collected particles.
