Abstract

See full text

The invention relates to a method for recovering energy and water from pressure oxidation flash steam where first flash steam directly obtained from a flash vessel is contacted with a first recirculating condensate having a first low condensate temperature to condense at least part of the water vapor in the first dirty flash steam and simultaneously to heat the first recirculating condensate to obtain a first recirculating condensate having a first high condensate temperature and a first vent steam. The invention further relates to a pressure oxidation arrangement adapted for use in the method.
