Abstract
METODO DE REEMPLAZAR UN REFRIGERANTE QUE CONTIENE BIFENILO POLICLORADO (BFP) EN UN APARATO ELECTRICO DE INDUCCION. COMPRENDE: A) ESCURRIR EL REFRIGERANTE QUE CONTIENE BFP, DEL DEPOSITO, PARA ELIMINAR LA MAYOR PARTE; B) LLENAR DICHO DEPOSITO CON UN LIQUIDO DIELECTRICO REFRIGERANTE PROVISIONAL QUE SEA MISCIBLE CON DICHO BFP, QUE TENGA UNA VISCOSIDAD SUFICIENTEMENTE BAJA PARA CIRCULAR DENTRO DE DICHO DEPOSITO, Y QUE SEA SUSCEPTIBLE DE SER SEPARADO DE DICHO BFP; C) PONER EN FUNCIONAMIENTO ELECTRICO DURANTE UN PERIODO SUFICIENTE PARA ELUIR DE EL EL BFP, QUE IMPREGNA A DICHO AISLAMIENTO SOLIDO POROSO, DICHO LIQUIDO DIELECTRICO REFRIGERANTE PROVISIONAL; D) ESCURRIR EL LIQUIDO DIELECTRICO REFRIGERANTE DE DICHO DEPOSITO; E) REPETIR EL CICLO DE LAS ETAPAS B), C) Y D) CUANDO LA VELOCIDAD DE ELUACION DE BFP A DICHO LIQUIDO DIELECTRICO REFRIGERANTE EXCEDE DE 0,55 PPM DE BFP POR DIA; Y F) LLENAR EL DEPOSITO CON UN REFRIGERANTE PERMANENTE, SIN BFP, ELEGIDO DEL GRUPO QUE CONSTA DE ACEITES DE SILICONA, FLUIDOS DE ESTER SINTETICO, Y OTROS QUE HIERVEN ALTO Y TIENEN ALTA VISCOSIDAD, PARA RECLASIFICAR DICHO APARATO ELECTRICO.
