Abstract

UN PROCEDIMIENTO DE DESPARAFINADO DE PETROLEO BRUTO MEDIANTE SOLVENTE, QUE PERMITE SEPARAR LA CERA CRISTALINA, DEL ACEITE LUBRICANTE MEDIANTE FILTRACION DE UNA MEZCLA CERA/ACEITE/SOLVENTE. SE SUMINISTRA UN ACEITE PARAFINADO A TRAVES DEL CONDUCTO (1), Y SE MEZCLA CON EL SOLVENTE SUMINISTRADO POR EL CONDUCTO (2) DESDE UNA SECCION DE RECUPERACION DE SOLVENTE. LA MEZCLA CERA/ACEITE/SOLVENTE, SE ALIMENTA A UN INTERCAMBIADOR DE CALOR (3), Y SE CALIENTA PARA ASEGURAR QUE TODOS LOS CRISTALES DE CERA SE DISUELVEN EN UNA VERDADERA DISOLUCION. ESTA MEZCLA CALIENTE SE DIRIGE A CONTINUACION, A TRAVES DEL CONDUCTO (4) A UN INTERCAMBIADOR DE CALOR (5), EN EL CUAL SE ENFRIA.
