Abstract

LA PRESENTE INVENCION SE REFIERE A LA RECUPERACION DE GAS DE OXIGENO DE BAJA PUREZA, DE LA PARTE SUPERIOR DE UNA CAMARA ADSORBEDORA, AL INTERIOR DE UN TANQUE RECEPTOR QUE SE UTILIZA COMO GAS DE PURGA EN REFLUJO. LA RECUPERACION DEL GAS INSERVIBLE TIENE POR RESULTADO UNA EFICIENCIA MEJORADA DEL PROCEDIMIENTO. LA INVENCION PUEDE EMPLEAR TAMBIEN UNA EVACUACION SIMULTANEA DESDE LA PARTE SUPERIOR DEL ADSORBEDOR, PARA EXTRAER EL GAS INSERVIBLE DE BAJA PUREZA, MIENTRAS SE LLEVA A CABO LA ETAPA PRINCIPAL DE EVACUACION DE RESIDUOS. ESTA RECUPERACION SIMULTANEA DEL GAS INSERVIBLE A FAVOR DE CORRIENTE DE LA PARTE SUPERIOR, Y DE LA EVACUACION A CONTRACORRIENTE DE RESIDUOS, DESDE AMBOS EXTREMOS DEL ADSORBEDOR, PERMITE UN AUMENTO GENERAL EN LA RECUPERACION DEL PRODUCTO DEL 3-5%, RESPECTO A PROCEDIMIENTOS CONVENCIONALES.
