Claim 1:
2. A method according to claim 1, wherein the existing plant comprises at least two evaporators in series, each said evaporator having a corresponding condenser and said evaporators each having a gas outlet to said corresponding condenser, each said condenser having a liquid outlet for sending condensed vapours to a liquid inlet of the water purification section, wherein the method comprises dividing the evaporation section in to a first stage upstream evaporation section and a second stage downstream evaporation section, thereby retaining in the first stage evaporation section the connection of the liquid outlet of the corresponding condenser to a liquid inlet of the water purification section, the method comprising providing the second stage evaporator with a connection to an outlet for utilized scrubbing liquid from the scrubbing system of the finishing section, and changing the liquid outlet of the corresponding second stage condenser from a connection to the water purification section into a connection for sending condensed vapours to a scrubbing system in the finishing section.
