Abstract
UN METODO Y COMPUESTO PARA PRODUCIR UN CRISTAL DE TRIHIDRATO DE ALUMINA MAS BASTO EN UN LICOR PORTADOR DE PROCESO BAYER COMPRENDIENDO LA ADICION DE APROXIMADAMENTE 5-400 MG/L E TENSIOACTIVO-ACEITE, DISOLVIENDO EL ACEITE EN TENSIOACTIVO QUE PUEDE SER SELECCIONADO DE UNA SUSTANCIA CONTENEDOR DE TENSIOACTIVOS QUE SON SOLUBLES EN SOLUCIONES CAUSTICAS (CALIENTES) Y SON CAPACES DE DISPERSAR LOS LIQUIDOS HIDROFOBOS EN EL LICOS BAYER. LA INCORPORACION PREFERENTE IMPLICA EL USO DE ACIDOS GRASOS DE TALLOIL, SE ESTABLECE UN NUMERO DE TENSIOACTIVOS EQUIVALENTES. EL ACEITE O HIDROCRBURO (HIDROFOBO) LIQUIDO PUEDE SELECCINARSE DE ACEITES PARAFINICOS, ACEITES NAFTENICOS, ACEITES MINERALES SELLANTES, ACEITES OMBUSTIBLES, Y HECES O RESIDUOS DE LA DESTILACION DE UN ALCOHOL C10.
