Abstract

2.1 PROCEDIMIENTOS Y DISPOSITIVOS CONOCIDOS PARA LA PURIFICACION DE SUSTANCIAS QUIMICAS FUNCIONAN DISCONTINUAMENTE CON PAREDES ENFRIADAS EN LAS QUE SE FORMA UNA CAPA DE CRISTALIZACION. ESTA CAPA SE SOMETE A UN PROCESO DE VAPORIZACION TRAS LA FORMACION DE CRISTAL, POR EL QUE SE PURGA LA SUPERFICIE ENSUCIADA. 2.2 SE PROPONE REALIZAR EL PROCESO DE VAPORIZACION EN UN DEPOSITO EN EL QUE SE RECOGEN LAS SUSTANCIAS QUIMICAS EN FORMA DE PASTILLAS SOLIDAS QUE LUEGO SE SOMETEN A UNA CORRIENTE DE AIRE CALIENTE EN LA QUE SE FUNDE SU SUPERFICIE. 2.3 USO PARA PURIFICACION DE SUSTANCIAS QUIMICAS
