Abstract

Patente de Invenção para "APARELHO PARA DISTRIBUIçãO DE GAS E LIQUIDO DURANTE CORRENTE DE GAS/LIQUIDO CONCORRENTE EM CALHAS DE DRENAGEM DE FILTRO". Um aparelho de distribuição de corrente concorrente para um filtro, tendo um tanque de filtro e uma pluralidade de laterais de drenagem, inclui uma chicana posicionada em um conduto principal comum, para definir uma calha auxiliar entre a chicana e as laterais de drenagem. A calha está em comunicação de fluido com o conduto principal comum e as laterais de drenagem. A chicana apresenta pelo menos um orifício de medição de líquido de calha preferivelmente localizado perto do fundo da chicana, de modo que ele pode estar abaixo de uma interface de gás/líquido na calha auxiliar durante operações de corrente de gás/líquido concorrente. Uma placa de distribuição de fluxo pode estar posicionada entre a calha auxiliar e as laterais de drenagem, a placa de distribuição de fluxo tendo pelo menos um orifício de medição de líquido e pelo menos um orifício de medição de gás. A chicana pode tomar uma de muitas formas. A chicana cria uma poça líquida adequada no conduto principal comum para fluxo de velocidade baixa de líquido de corrente, enquanto, ao mesmo tempo, proporciona fluxo não-inibido de gás de corrente. A mal distribuição é, desse modo, controlada. Tubos de subida podem ser usados no lugar da chicana. Um processo para corrente de gás/líquido concorrente, de acordo com a invenção, é também revelado. A invenção pode ser aplicada em calhas de fundo plano, ou calhas insuficientemente recessadas.
