Abstract

"PROCESSO PARA INTRODUZIR GáS DENTRO DE UMA POçA DE LìQUIDO". Processo para a introdução de gás dentro de um líquido no qual uma corrente de gás é ejetada de uma lança espaçada acima da superfície do líquido e direcionada da lança para cima da superfície de líquido. O gás retém substancialmente toda a sua velocidade do eixo do jato original quando contacta a superfície do líquido, e substancialmente todo o gás penetra na superfície do líquido e é introduzido no líquido. De preferência, a corrente de gás está rodeada por um envelope de chama correndo da lança para a superfície do líquido, que protege o gás contra a entrada de gás ambiental. A corrente de gás forma preferivelmente uma cavidade gasosa dentro do líquido possuindo um diâmetro substancialmente igual ao diâmetro da corrente de gás assim que ela é ejetada da lança.
