MASS-TRANSFER IN JET LOOP REACTORS

A study has been carried out regarding the performance of a loop reactor with a liquid driven jet ejector. The mass transfer inside the two phase jet in the ejector as well as the mass transfer in the bulk fluid of the vessel were separately determined. The desorption of oxygen from water into nitrogen gas was used as a model system. The results prove that it is essential for the proper design of jet loop reactors to consider the ejector and the vessel as a system of two reactors in series, requiring individual modelling. Furthermore it is demonstrated that the mass transfer in the entire reactor system is considerably influenced by the flow regime in the ejector. © 1990.
