Abstract
USO DE SISTEMAS POLIMERICOS DE DOS FASES PARA ELIMINAR CONTAMINANTES MICROBICOS DE AGENTES LUBRICANTES INDUSTRIALES, UN METODO DE PURIFICAR AGENTES LUBRICANTES CONTAMINADOS POR MICROBIOS MEZCLANDO EL AGENTE LUBRICANTE CON UN SISTEMA POLIMERICO DE DOS FASES, PERMITIENDO QUE LA MEZCLA SE SEPARE PARA FORMAR UNA FASE SUPERIOR QUE CONTENGA EL AGENTE LUBRICANTE Y UNA FASE INFERIOR QUE CONTENGA POR LO MENOS PARTE DE LOS CONTAMINANTES MICROBICOS, Y SEPARANDO POR LO MENOS UNA GRAN PARTE DE LA FASE INFERIOR ENRIQUECIDA MICROBIALMENTE DE LA FASE SUPERIOR, UNA INSTALACION PARA LA PURIFICACION MICROBICA DE AGENTES LUBRICANTES QUE COMPRENDE UN TANQUE MEZCLADOR (4) CON ELEMENTOS (7, 8) PARA SUMINISTRAR AGENTE LUBRICANTE CONTAMINADO POR MICROBIOS (S) AL TANQUE MEZCLADOR, ELEMENTO (3) PARA SUMINISTRAR UN SISTEMA POLIMERICO DE DOS FASES AL TANQUE MEZCLADOR, UN AGITADOR (5) EN EL TANQUE MEZCLADOR, ELEMENTOS (9, 10) PARA SUMINISTRAR LA MEZCLA AL DISPOSITIVO DE SEPARACION (6) PARA SEPARAR LA MEZCLA EN UNA FASESUPERIOR (T) QUE CONTIENE AGENTES LUBRICANTES, Y UNA FASE INFERIOR (B) QUE CONTIENE CONTAMINANTES MICROBICOS, Y ELEMENTOS (18) PARA RECUPERAR LA FASE SUPERIOR DEL SISTEMA DE DOS FASES, Y UN AGENTE LUBRICANTE CONCENTRADO, EN EL QUE POR LO MENOS UNA PARTE DE AGENTE LUBRICANTE FORMA PARTE AL MISMO TIEMPO DEL COMPONENTE DE FASE SUPERIOR DEL SISTEMA POLIMERICO DE DOS FASES.
