Abstract

UNA LECHADA DE REFINERIA (1) QUE CONTIENE AGUA, ACEITE Y UNA FRACCION SOLIDA SE PONE EN CONTACTO CON GAS DIOXIDO DE CARBONO (2) CON EL OBJETO DE AJUSTAR EL VALOR PH DE DICHA LECHADA EN UN VALOR ACIDO Y, DE ESA FORMA MEJORAR LA SEPARACION, POR MEDIOS MECANICOS, DE UNA PRIMERA FASE DE AGUA (4) Y UNA PRIMERA FASE DE ACEITE (5), DE UN LODO. ESTE ULTIMO SE SOMETE A UNA EXTRACCION CON DIOXIDO DE CARBONO, BAJO CONDICIONES SUPERCRITICAS, CON EL OBJETO DE SEPARAR UNA SEGUNDA FASE DE AGUA (8) Y UNA SEGUNDA FASE DE ACEITE DE UN RESIDUO DE LODO (9) DEL QUE SE DESPRENDE. EL PROCESO HACE POSIBLE QUE LA MAYOR PARTE DEL AGUA Y, EN PARTICULAR, LA MAYOR PARTE DEL ACEITE DEL LODO MENCIONADO SEA EXTRAIDO Y EL LODO SEA ELIMINADO, QUE MUESTRA UNA PROPENSION REDUCIDA A LA ELUCION DEL ACEITE RESIDUAL.
