Abstract
SE GENERA UNA PUREZA OPTIMA, P. EJ., NITROGENO QUE TIENE MENOS DE 0,1 PPM DE IMPUREZAS LIGERAS, CON NITROGENO MEJORADO EN UN PROCESO CRIOGENICO POR LA SEPARACION DE AIRE UTILIZANDO UN SISTEMA DE DESTILADO DE VARIAS COLUMNAS INTEGRADO QUE COMPRENDE UNA PRIMERA COLUMNA (102) Y UNA COLUMNA DE NITROGENO DE PUREZA OPTIMA (104) MEDIANTE LA SEPARACION DEL NITROGENO LIQUIDO DE LA PRIMERA COLUMNA, CARGA DE ESA PARTE (20) MIENTRAS ALIMENTA A LA COLUMNA DE NITROGENO DE PUREZA OPTIMA, SEPARACION DE UN CHORRO DE NITROGENO (14) QUE ES RICO EN CONTAMINANTES VOLATILES DESDE LA PARTE SUPERIOR DE LA PRIMERA COLUMNA, CONDENSACION PARCIAL (EN 108) DE ESE CHORRO DE NITROGENO, ELIMINACION DE LA PARTE NO CONDENSADA (18) QUE HA SIDO CONCENTRADA EN CONTAMINANTES VOLATILES COMO UN CHORRO DE DEPURACION, Y DEVOLUCION DE LA PARTE CONDENSADA (16) AL SISTEMA DE DESTILADO COMO REFLUJO.
