Abstract

UN SECADOR (2) SEPARADO CON RESPECTO A LA INSTALACION (2) DE DESDOBLAMIENTO POR MEDIO DE UNA ESCLUSA (3) DE MATERIAL SOLIDO SE CALIENTA POR ENCIMA DE 200 DE CIRCULACION DE VAPORES DE EXHAUSTACION, CALENTADOS POR MEDIO DE UN INTERCAMBIADOR TERMICO CON EL GAS DE ESCAPE A PARTIR DE LA PLANTA (1) DE DESDOBLAMIENTO DE TAL FORMA QUE SE ELIMINA TAMBIEN EL AGUA DE CRISTALIZACION, JUNTO A LA HUMEDAD RESIDUAL. EL ANHIDRIDO (SO2) ACIDO LIBRE DE VAPOR SE PREPARA EN LA INSTALACION (1) DE DESDOBLAMIENTO SUBSECUENTE A PARTIR DE LA SAL DESHIDRATADA, MIENTRAS QUE EL OXIDO METALICO SE RECUBRE O SE UTILIZA DE OTRA FORMA. EL ANHIDRIDO ACIDO PUEDE SER LICUADO Y POR ESO SU PUREZA PERMITE QUE SEA VENDIDO EN EL MERCADO.
