Abstract: 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.

Abstract: The invention relates to a method of recovering energy and water from pressure oxidation flash steam comprising a step wherein a first flash steam directly obtained from a flash vessel is contacted with a first recirculating condensate having a first low condensate temperature to con-dense at least part of the water vapour comprised in the said first dirty flash steam on the first recirculating condensate and simultaneously to heat the said 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 recovering energy from pressure oxidation flash steam and to a use of high temperature condensate and to a use of a direct contact condenser for recovery of energy and water from a pressure oxidation flash steam.
