Abstract

METODO EL CUAL INCLUYE EL PASO DE UN CHORRO DE GAS CONTENIENDO DIOXIDO DE CARBONO, HIDROGENO SULFURADO, DIOXIDO DE SULFURO, COMPUESTOS DE SULFURO Y OTROS GASES ACIDOS A TRAVES DE UNA SOLUCION DE ALCANOTIOL ACUOSO, PARA ELIMINAR EL DIOXIDO DE CARBONO, HIDROGENO SULFURADO, DIOXID DE SULFURO COMPUESTOS DE SULFURO, ETC., DEL CHORRO DE GAS. SALES DE ALCANOTIOL TERMOESTABLES EXISTENTES EN LA SOLUCION DEBIDO A LOS CONTAMINANTES ACIDOS (TALES COMO HIDROGENO SULFURADO O DIOXIDO DE CARBONO) SON ELIMINADOS DE LA CORRIENTE GASEOSA. UNA BASE ES AÑADIDA A LA SOLUCION DE ALCANOTIOL ACUOSO PARA CONVERTIR TODO O PARTE DE LAS SALES DE ALCANOTIOL TERMOESTABLE EN ALCANOTIOL Y SALES SIMPLES. LA BASE EMPLEADA ES ELECTRODIALIZADA EN UNA CELULA DE ELECTRODIALISIS CONTENIENDO MEBRANAS DE INTERCAMBIO DE IONES. LA SOLUCION DE ALCANOTIOL ACUOSO PURIFICADA PUEDE SER USADA DE NUEVO PARA ELIMINAR DIOXIDO DE CARBONO, ETC., DE LA CORRIENTE DE GAS.
