Abstract

"CéLULA DE FLOTAçãO INDUZIDA POR GáS VERTICAL". A presente invenção refere-se a um sistema para separar óleo e/ou sólidos revestidos de óleo de uma mistura de água oleosa. O sistema inclui um vaso vertical tendo uma entrada para introduzir água oleosa em um padrão horizontal. O vaso também tem uma saída de água em uma parte inferior do vaso e uma saída de óleo. Um duto de descarga é posicionado dentro de uma parte inferior do vaso e é disposto para disseminar pequenas bolhas de gás em um padrão radial substancialmente horizontal e de maneira substancialmente uniforme em toda a área da seção transversal do vaso. As bolhas migram ascendentemente contra fluxo descendente de água oleosa dentro do vaso e se prendem às gotículas de óleo e/ou sólidos revestidos de óleo aumentando flutuação dos mesmos e, deste modo, melhorando a separação do óleo contaminante da água. Um depósito de escuma de óleo de dois estágios está localizado em uma parte de topo do vaso por meio do qual o óleo separado é coletado e descarregado através da saída de óleo.
