Abstract

Patente de Invenção de ''DISPOSITIVO MISTURADOR POR CISALHAMENTO, MéTODO PARA GERAR BOLHAS DE GáS EM UM LìQUIDO E MéTODO PARA PRODUZIR UMA CLORIDRINA DE OLEFINA", para produzir, de um modo controlável e económico, pequenas bolhas de gás tendo, por exemplo, um diâmetro médio de cerca de 0,5 milímetro em um líquido, com o que a transferência de massa do gás para dentro do líquido é melhorada (se comparada com a transferência de massa obtida com os geradores de bolhas grandes convencionais, sob as mesmas circunstâncias) em aplicações que se beneficiam da referida transferência de massa melhorada, envolvendo a injeção de um gás sob pressão, através de um ou mais orifícios dentro de um líquido que está fluindo a uma velocidade suficiente para fazer com que as bolhas formadas no (s) orifício (s) sejam subdivididas para o desejado pequeno tamanho de bolha.Invention Patent for '' MIXING DEVICE BY SHEARING, METHOD FOR GENERATING GAS BUBBLES IN A LIQUID AND METHOD FOR PRODUCING AN OLEPHINE CHLORHYDRINE ', to produce, in a controllable and economical way, small gas bubbles having, for example, a average diameter of about 0.5 millimeters in a liquid, with which the mass transfer of the gas into the liquid is improved (compared to the mass transfer obtained with conventional large bubble generators, under the same circumstances) in applications that benefit from said improved mass transfer, involving the injection of a gas under pressure, through one or more orifices within a liquid that is flowing at a speed sufficient to cause the bubbles formed in the orifice (s) (s) are subdivided into the desired small bubble size.
