Abstract
Det er beskrevet anvendelse av plastiske materialer og støpematerlaler samt svelsetllsatsmaterlaler av austenittiske Jern-nikkei-krom-sillslum-legerlnger for bygningsdeler som kommer l kontakt med konsentrert svovelsyre/oleum ved temperaturer mellom > 200*C og kokepunktet for den tilsvarende anvendte svovelsyre/- oleum. Det er videre beskrevet en fremgangsmåte for fremstilling av svovelsyre under anvendelse av disse materialene samt en fremgangsmåte for konsentrering og rensing av svovelsyre likeledes ved anvendelse av de nevnte materialene.
