INTRODUCTION

In the chemical process industries, several reactions involve the use of pure gas to accomplish desired chemical reactions.

The unused gas is collected in the head space of the reactor above the liquid level. This gas is recirculated through the hollow shaft and re-induced through the gas inductors mounted below the liquid level.

Instead of churning the liquid reaction mass, a hollow agitator pumps gases from the head space to the lowest part of the reactor vessel. Hollow shaft with high mass transfer gas induction impeller, pitch blade turbine, axial propeller, paddle etc.

The special gas induction impeller vigorously disperses these gases into the bottom of the reactor; Gas bubbles react with liquid/slurry as they rise. Unreacted gases are re-induced into the liquid. The pitch blade turbine breaking Bubbles and the propeller lift and recycle catalyst at the bottom, so as to achieve a a full reaction.  

Applications: 

Applications : Alkylation | Amination | Chlorination | Carboxylation | Ethoxylation | Hydrogenation | Oxidation | Gas slurry reaction 

Features: 

A high induced gas flow rate

A fine dispersion of the gas and therefore a large Gas-Liquid interfacial area

Through suspension of solid components (e.g., Catalyst)

Stable mechanical operation at moderate (sub-critical) stirrer speed

Recirculation of the unused gas

Reduced batch times
