Abstract

An apparatus for distillation of a purifyable liquid near or above its critical point, wherein the purifyable liquid contains a dissolved solid. The apparatus comprises a separation vessel (2) for separating the liquid into a vapour phase in a super residue separated by a liquid surface within said separation vessel (2), heat exchange means (4) for transmitting heat from the vapour phase and liquid residue and from the vapour phase and the liquid residue to the purifyable liquid, means (6) for pumping the purifyable liquid into said heat exchange means (4) and for feeding the purifyable liquid into the separation vessel (2) for separating the purifyable liquid into the vapour phase and the liquid residue separated by the liquid surface, the separation vessel (2) has a liquid inlet (2a), a vapour outlet (2b) and a residue outlet (2c). The vapour outlet (2b) is positioned at the top of the separation vessel (2). The liquid inlet (2a) is positioned at the bottom of the separation vessel (2), and the liquid residue outlet (2c) is positioned in the separation vessel (2) between the Hq- uid inlet (2a) and the vapour outlet (2b) and immediately below the surface of the liquid. The apparatus also comprises means for establishing a pressure and a temperature in the separation vessel (2) sufficient to bring the liquid to a state near or above the critical point. The means for pumping the purifyable liquid comprises at least three reciprocating pumps (6a, 6b, 6c) with vertical displacement means for supplying liquid into the heat exchanger and withdrawal of liquid residue from the heat exchanger 4 and withdrawal of the distillate from the heat exchange means (4). As a result of the vertical positioning of the displacement means the volume over the displacement means could be used for sensing of different operational parameters and problems in connection with upstart of the apparatus may be omitted.
