Abstract

PROCESO EN EL CUAL SE CANALIZA EN PRIMER LUGAR UNA MEZCLA DE VAPORES DE AGUA Y DE AIRE ENRARECIDO EN FLUJO ASCENDENTE (19) Y QUE A CONTINUACION LA MEZCLA FLUYE EN UN FLUJO DESCENDENTE (23) EN UN RECINTO (34) MANTENIDO EN DEPRESION. UNA SOLUCION ACUOSA ALCALINA ES PULVERIZADA EN UNA CIRCULACION PARALELA A DICHO FLUJO DESCENDENTE Y LOS GASES NO CONDENSADOS DESCONTAMINADOS SON EVACUADOS DEL RECINTO POR UNA CORRIENTE FORZADA Y REGULABLE QUE CREA Y MANTIENE UNA DEPRESION EN EL INTERIOR DE DICHO RECINTO. LA PRESENTE INVENCION DESCRIBE TAMBIEN UN DISPOSITIVO PARA LA PUESTA EN MARCHA DE DICHO PROCESO.
