GAS INDUCING MIXERS FOR THE FOOD & CHEMICAL INDUSTRY PROCESS: Gas/liquid reactions with pure gases Hydrogenated fatty acids – pharmaceuticals – hydrometallurgical products Hydrogenation – Chlorination – Oxidation – Alkoxylation – Amination – Carboxylation We offer maximum reliability, high durability and stirring efficiency Process description The aim of the gas-liquid contact is a chemical or bio-chemical reaction between the gas and the liquid phase. The dissolution rate (the mass transfer) between the phases must be sufficient for the demand by the reaction rate in the liquid phase. The mass transfer depends not only on the gas flow but is also enhanced by the stirring power. Traditionally a so-called “surface aerator” which created a large vortex to accomplish the reaction was used. The JONGIA gas inducing mixer is a stirrer system for gasliquid reactors, providing gas recirculation from the headspace of the reactor through the hollow stirrer shaft without an additional gas compressor. It provides an excellent mass transfer rate and rules have been established for the prediction of the transfer coefficients depending on the physical properties of the gas-liquid system, the dimensions and operating conditions. 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. Major players in the industries such as Cargill, Croda, Bunge Loders Croklaan use JONGIA mixing equipment in their production facilities. Installations are up and running world-wide from as far back as

GAS INDUCING MIXERS FOR THE FOOD & CHEMICAL INDUSTRY Product information Jongia meets the challenge of modern-day high productivity requirements with its novel gas-inducing system. In a simple reactor a gas-inducing coil the so-called sparger is installed for the primary gas supply. The gas from the head space of the reactor is recirculated through the hollow shaft and re-induced through the gas inductors mounted below. The main mixing element creates an under-pressure at the gas inductors to disperse the gas into the reaction media. Depending on the batch sizes required one or more...
