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:

The hydrogenation reaction usually involves a three-phase slurry- the liquid oil, the solid catalyst in slurry phase and the hydrogen bubbles as the gas phase. As there are a number of phase boundaries the mass transfer, and especially the hydrogen dispersion, is a very important factor. The mixing system that is employed in the reactor influences the mass transfer cofficient of the gas-liquid.
