    摘要： The following process steps are carried out in order to purify a liquid by membrane distillation, in particular to produce desalinated water from seawater or brackish water or process water:passing a relatively warn vaporising stream of liquid (retentate stream) over a porous membrane, vapour flowing via the pores of the membrane to the other side of said membrane, andcondensing said vapour on a relatively cool condenser surface to give a distillate stream, said condenser surface forming the non-porous separation between a feed stream to be purified and said distillate steam, which feed stream is in counter-current with the retentate stream so that an appreciable proportion of the latent heat will be transferred via vapour to the feed stream, and a gas gap with a width of less than 5 mm being present between the porous membrane and the condenser surface.In order to improve the distillate flow rate per unit driving force, a pressure which is lower than the atmospheric pressure and higher than the vapor pressure of the feed stream is maintained in the gas gap, the porosity epsilon of the porous membrane is higher than 0.7, porosity being understood to be the ratio of the open volume to the total volume of the porous membrane, the surface area of the condenser surface is 1.2 to 6 times, preferably 2 to 3 times, the surface area of the porous membrane, the effective local vapour pressure difference between the retentate seam and the condensing stream is less than 10 kPa (0.1 bar), preferably less than 5 kPa (0.05 bar) and the perceptible heat of the distillate stream is released by heat exchange to the feed stream and/or the retentate stream, with preference for the retentate stream.

    摘要： The present invention relates to a reactor for carrying out gas phase/liquid phase/solid phase reactions, comprising a housing (1) which encloses an essentially closed reaction chamber (2) for holding a first liquid phase, the solid phase and a gas phase (fed through said chamber); at least one feed (3), connected to the reaction chamber, for feeding a first liquid phase to the reaction chamber (2); at least one hollow fibre (4), the wall of which defines an internal flow channel for at least removing a second liquid phase, such that exchange of matter can take place between the reaction chamber (2) and the flow channel through the wall of hollow fibre (4); at least one discharge (6), connected to the flow channel, for removing the second liquid phase; at least one gas inlet (7) and at least one gas outlet (8), connected to reaction chamber (2) such that, in the use position, the at least one gas inlet (7) opens essentially into the bottom of the reaction chamber (2) and the at least one gas outlet (8) is located essentially at the top of the reaction chamber (2), for feeding the gas phase essentially in the upward direction through the reaction chamber (2). The invention further relates to a method for carrying out gas phase/liquid phase/solid phase reactions, using the above reactor. The hollow fibres are preferably of a ceramic material. The reactor is preferably a DAM module and/or suitable for use at elevated temperature and pressure.
