Exhaust air purification for propellant gas filling
They can be found in many households and have become indispensable in the catering, confectionery, and patisserie industries: compressed gas cylinders for whipping cream or – especially in professional kitchens – for flavoring or for making espumas, desserts, sauces and much more. The small steel capsules are filled with pure N2O, nitrous oxide – also known colloquially as laughing gas.
Any gas that escapes during the production or filling of these pressurized gas cylinders is extracted directly from the filling machines. The ReiCat waste gas purification system is used before this waste gas is emitted in an uncontrolled manner. Using a blower, the N2O is fed into the catalytic exhaust air purification system. Here, the exhaust gas is purified and the nitrous oxide is decomposed, thus meeting the air pollution control requirements. The implemented heat recovery ensures the highest possible energy efficiency.
The system shown here has a capacity of up to 1,600 Nm³/h. The small space requirement (approx. 4 m²) allows easy implementation on site. This exhaust gas system is designed for outdoor installation and is fitted with a deflector hood for the exhaust air pipe.
