Abstract

LA INVENCION TRATA DE UN PROCEDIMIENTO PARA LA ALIMENTACION DE GAS PROTECTOR EN UN HORNO DE UN TRATAMIENTO TERMICO (D) CON OPCIONALMENTE VARIAS CAMARAS O ZONAS, P. E. UNA ZONA DE ENTRADA Y SALIDA ASI COMO UNA ZONA DE TRATAMIENTO, EN LA CUAL EL CALOR SE PRODUCE POR COMBUSTION DE UN HIDROCARBURO GASEOSO EN DISPOSITIVOS DE CALENTAMIENTO (H), EN PARTICULAR TUBOS EYECTORES, Y SE PRODUCE EL GAS PROTECTOR PARA EL TRATAMIENTO TERMICO Y SE RECUPERA UTILIZANDO LA PARTE DE DIOXIDO DE CARBONO DEL GAS QUE SALE DE LA COMBUSTION, SEPARANDOSE EL DIOXIDO DE CARBONO DEL GAS QUE SALE, SE JUNTA CON GAS QUE CONTIENE HIDROCARBURO, Y SE HACEN REACCIONAR OBTENIENDOSE UNA MEZCLA GASEOSA UTIL DE GAS PROTECTOR, Y SE VUELVE ESTE GAS AL HORNO. DE ACUERDO CON LA INVENCION SE PROPONE PARA TAL PRINCIPIO DE PROCEDIMIENTO, QUE LA SEPARACION DEL CO{SUB,2} DE GAS QUE SALE SE LLEVE A CABO CON UNA INSTALACION DE SEPARACION DE GAS CON MEMBRANA, ESTANDO CONECTADAS A ESTA SEPARACION UNA REFRIGERACION Y COMPRESION DE GAS DE TAL MANERA, QUE SE RETIRE LA PARTE DE VAPOR DE AGUA EN EL GAS QUE SALE, Y QUE LA FRACCION DE GAS QUE CONTIENE MAYORMENTE NITROGENO QUE SE FORMA EN LA SEPARACION SE OBTIENE CON MAS DEL 95 % DE PUREZA, Y SE UTILIZA EN EL MISMO HORNO DE TRATAMIENTO TERMICO TAMBIEN COMO GAS PROTECTOR, INTRODUCIENDOSE ESTE GAS PROTECTOR DE NITROGENO A DISTANCIA DEL GAS QUE SE GENERA EN EL HORNO, EN PARTICULAR CUANDO HAY VARIAS ZONAS EN EL HORNO, INTRODUCIENDOSE COMO GAS PROTECTOR EN LA ZONA DE ENTRADA Y OPCIONALMENTE EN LA DE SALIDA.
