Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA DETERMINAR LA TENSION SUPERFICIAL EN UN LIQUIDO GENERANDO BURBUJAS DE GAS EN EL LIQUIDO. LAS BURBUJAS DE GAS SE FORMAN PREFERIBLEMENTE A PARTIR DE UN GAS QUE SE GENERA IN SITU Y LAS BURBUJAS DEL GAS SON MONITORIZADAS PREFERIBLEMENTE IN SITU, POR EJEMPLO, MEDIANTE UN ELECTRODO. LA TENSION SUPERFICIAL PUEDE MEDIRSE DURANTE UN PROCESO DE LAVADO. LOS ELECTRODOS PREFERIDOS QUE PUEDEN UTILIZARSE EN EL PROCESO SON ELECTRODOS QUE CONTIENEN SOLAMENTE UNA ZONA DE NUCLEACION. EL PROCESO SE REALIZA PREFERIBLEMENTE UTILIZANDO UN APARATO QUE CONTIENE UNA UNIDAD DE GENERACION DE BURBUJAS DE GAS Y UNA UNIDAD DE DETECCION PARA MONITORIZAR LAS BURBUJAS DE GAS, EN DONDE LA UNIDAD DE DETECCION GENERA PREFERIBLEMENTE UNA SEÑAL QUE SE UTILIZA PARA EL CONTROL DE REALIMENTACION DE LA UNIDAD DE GENERACION DE BURBUJAS DE GAS.
