Abstract

PROCEDIMIENTO DE REGULACION DEL CALOR APORTADO A UNA COLUMNA DE DESTILACION POR EXTRACCION. CONSISTE EN SUBDIVIDIR EN DOS PARTES LA CANTIDAD DE CALOR A APORTAR EN PROPORCIONES QUE OSCILAN ENTRE EL 80-90 POR 100 Y EL 20-10 POR 100. COMO CRITERIOS DE ESTA REGULACION SE EMPLEAN O BIEN LA DIFERENCIA DE TEMPERATURA DEL LIQUIDO ENTRE DOS PLATOS SITUADOS EN LA PARTE SUPERIOR DE LA COLUMNA, O LA CONCENTRACION DE LA SUSTANCIA A EXTRAER DETERMINADA MEDIANTE UN CROMATOGRAFO DE GAS SITUADO EN UNO DE LOS PLATOS DE LA PARTE SUPERIOR DE LA COLUMNA. EL CALOR ES APORTADO A TRAVES DE UNO O VARIOS REEBULLIDORES. EN CASO DE EMPLEARSE VARIOS, PUEDEN EMPLEARSE DIFERENTES PORTADORES DE CALOR. N
