Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA LA ELIMINACION DE GAS DE OXIDO METILENO EN ALTAS CONCENTRACIONES, POR EJEMPLO 1,000 A 1,000,000 PPM, TAL Y COMO SUCEDE EN LAS CAMARAS DE ESTERILIZACION CON GAS. EL PROCESO DE ELIMINACION PROPONE QUE EL GAS DE OXIDO ETILENO SEA ABSORBIDO POR MEDIO DE UN ABSORBENTE EN ESTADO SECO Y/O SEA ABSORBIDO EN FORMA DE REACCION CATALITICA POR UN ABSORBENTE Y/O PORTADOR CATALITICO EN ESTADO HUMEDO EN PRESENCIA DE UN CATALIZADOR Y/O AGENTE OXIDANTE O REDUCTOR O PORTADOR DE AGENTE DE REDUCCION QUE PUEDE ACTUAR COMO UN CATALIZADOR Y/O CUERPO DE RELLENO, DEPENDIENDO DEL AGENTE USADO COMO REDUCTOR U OXIDANTE, EN ESTADO HUMEDO, CON LA ADICION DE UN AGENTE DE REDUCCION U OXIDACION.
