Through our designs, we ensure that during rotation of the impeller, a vacuum is created at the tip due to Venturi action. This vacuum overcomes the liquid head. Fresh or unreacted gases from the vessel upper crest re-circulate into the liquidslurry through the hollow shaft. Higher gas flow rates and finer bubbles sizes impart a very high gas-liquid interfacial area. A unique flow pattern provides desired movement of the catalyst and excellent contact of the gases with the catalyst or solids.
