Abstract

PROCEDIMIENTO PARA LA PREPARACION EN CONTINUO DE SOLUCIONES ACUOSAS DE FORMALDEHIDO, EN EL QUE SE UTILIZA UNA COLUMNA DE ALIMENTACION Y UNOS INTERCAMBIADORES ADICIONALES DE CALOR RELACIONADOS CON UNAS COLUMNAS DE ABSORCION; EN LA COLUMNA DE ALIMENTACION ENTRA AIRE Y METANOL PROCEDENTES DEL EXTERIOR, ASI COMO UNA SUBCORRIENTE DE METANOL, ORIGINADA DE UNA CORRIENTE DE METANOL FRIO QUE SALE DE LA COLUMNA DE ALIMENTACION; ESTA CORRIENTE DE SALIDA RECIRCULA POR LOS INTERCAMBIADORES ADICIONALES DE CALOR Y SE DIVIDE EN LA SUBCORRIENTE QUE RETORNA A LA COLUMNA DE ALIMENTACION Y EN OTRA SUBCORRIENTE QUE ALCANZA UN EVAPORADOR; DE LA CABEZA DE LA COLUMNA DE ALIMENTACION, SALE UNA MEZCLA METANOL Y AIRE, QUE ALCANZA UN EVAPORADOR. EL METANOL FRIO SE ENFRIA EN EL INTERIOR DE LA COLUMNA DE ALIMENTACION, POR LA EVAPORACION DEL METANOL QUE FORMA PARTE DE LA MEZCLA DE METANOL Y AIRE.
