Agitateur à induction de gaz
2020-02-25
The HXCHEM gas inducing agitator is a stirrer system for gas-liquid reactors, providing gas recirculation from the headspace of the reactor through the hollow stirrer shaft without an additional gas compressor. There will only be low concentrations of catalysts required in the reactor due to high rates of mass transfer which also contributes to short mixing times.
Features:
High induced gas flow rate.
A fine dispersion of the gas and therefore a large interfacial area.
Accurately predicted excellent mass transfer also on large scale.
Stable magnetic coupling operation at.
Moderate (sub-critical) stirrer speed.
Recirculation of the unused gas.
Applications:
1. Catalytic hydrogenation
2. Gas-liquid reaction with suspended Solids
3. Gas-slurry reactions、
4. Carboxylation
5. Ozonisation/Oxidation
6. Amination/Aminolysis
Hydrogenation reactors:
La réaction d'hydrogénation implique généralement une suspension en trois phases - l'huile liquide, le catalyseur solide en phase de suspension et les bulles d'hydrogène en tant que phase gazeuse. Comme il existe un certain nombre de limites de phase, le transfert de masse, et en particulier la dispersion d'hydrogène, est un facteur très important. Le système de mélange utilisé dans le réacteur influence le transfert de masse du gaz-liquide.
