Abstract

<B><MU>PROCESSO PARA DETERMINAR A QUANTIDADE DE GáS, NA FORMA DE BORBULHAS E NO ESTADO DISSOLVIDO<MV><D>. A presente invenção refere-se a um processo para determinar a quantidade de gás em um líquido. O processo é particularmente adequado para determinar a quantidade tanto de gás na forma de borbulhas, quanto do gás dissolvido na polpa, isto é, nas várias suspensões de fibras na indústria de papel e de polpa. A invenção é aplicada vantajosamente e aplicações de controle e regulagem de remoção de ar, na circulação curta de uma máquina de fabricação de papel.
