Abstract

"APARELHO E MéTODO DE SEPARAçãO". A presente invenção refere-se a um aparelho e método de separação são utilizados usando um canal de separação (210) para rotação ao redor de um eixo. Tal canal inclui porções de parede lateral interna (206) e externa (208) radialmente separadas e uma porção de parede de extremidade (224). Uma entrada (226) transporta o fluido para dentro do canal. Uma barreira (232) fica localizada no canal intermediária às porções de parede lateral interna e externa. Uma primeira trajetória de fluxo se comunica entre os lados a montante e a jusante da barreira. Uma região de coleta pode ser localizada a jusante da barreira para comunicação com a primeira trajetória de fluxo. Uma seção de parede lateral externa do canal pode ser posicionada radialmente para fora de uma seção a montante da mesma. A barreira (232) pode unir a porção da parede lateral externa (208) ao longo de uma porção substancial de um comprimento axial do canal. Primeira e segunda trajetórias do fluxo de saída podem permitir a comunicação com o canal a montante ou a jusante da barreira ou ambos.
