Abstract
UN METODO PARA SEPARAR HFA 134A DE UNA MEZCLA RICA EN HFA 134A, CON HF Y/O CFC 1122 QUE COMPRENDEN LA ALIMENTACION DE LA MEZCLA A UNA COLUMNA DE DESTILACION PARA SEPARAR UN AZEOTROPO O CERCANO A UN AZEOTROPO DE HFA 134A Y HF Y/O CFC 1122, DE UN RESIDUO QUE COMPRENDE SUSTANCIALMENTE HFA 134A PURO. PARTIENDO DE UNA MEZCLA RICA EN HF DE HFA 234A TAL COMO UNA CORRIENTE DE PRODUCTOS TIPICA EN LA PRODUCCION DE HFA 134A, EL METODO INCLUYE UN PRIMER PASO DE DESTILACION PARA SEPARAR EL HF DE LA MEZCLA INICIAL Y PRODUCIR UN AZEOTROPO O CERCANO A UN AZEOTROPO DE HFA 134A Y HF QUE ES UNA MEZCLA RICA EN HFA 134A.
