Abstract
PROCEDIMIENTO PARA LA OBTENCION DE ACIDO SULFURICO A PARTIR DE GASES QUE CONTIENEN SO2, DESPUES DE UN LAVADO EN HUMEDO.CONSISTE EN LA OXIDACION CATALITICA EN VARIAS ETAPAS DE SO2 A SO3, DESPUES DE LA EXTRACCION DE UNA PARTE DEL AGUA CON ACIDO SULFURICO DE 40-80 Y POSTERIOR SECADO CON ACIDO SULFURICO CONCENTRADO; Y ABSORCION DEL SO3 FORMADO EN DOS ETAPAS. EL ACIDO DE SECADO CON EL AGUA RETENIDA SE UTILIZA COMO ACIDO DE ABSORCION DE SO3.
