Abstract

Det er beskrevet en fremgangsmåte til regenerering av van- dige klorid-lutevaesker. Fremgangsmåten innbefatter røsting av vandig klorid-lutevaeske for å frembringe metalloksyd og en gass inneholdende HC1. Gassen som inneholder HC1 føres gjen- nom en forkonsentrator (3) hvor den bringes i kontakt med vandig klorid-avlut. Gassens varmeinnhold fordamper vann fra avluten, slik at den konsentreres. På samme tid absorberer avluten HC1. HC1 som ikke er absorbert i forkonsentratoren ('3) bringes i kontakt med vann til dannelse av saltsyre. Saltsyren kan blandes med den konsentrerte avlut og benyttes om igjen. Det er likeledes beskrevet apparatur for utførelse av fremgangsmåten. syre fra roganererlngA process for regenerating aqueous chloride lute liquors is disclosed. The process includes roasting aqueous chloride lute fluid to produce metal oxide and a gas containing HCl. The gas containing HCl is passed through a preconcentrator (3) where it is contacted with aqueous chloride effluent. The heat content of the gas evaporates water from the liquor so that it is concentrated. At the same time, the liquor absorbs HCl. HCl not absorbed in the preconcentrator ('3) is contacted with water to form hydrochloric acid. The hydrochloric acid can be mixed with the concentrated effluent and reused. Apparatus is also described for carrying out the method. acid from roganation
