Abstract: A device for the electrodeionization of an aqueous electrolyte solution, comprises an electrodeionization module (1), an ultrafiltration module (21, 22, 1201, 1202, 1203) and a connection piece (3, 10) which connects the electrodeionization module (1) and the ultrafiltration module (21, 22, 1201, 1202, 1203) such as to be able to guide a diluate produced from the electrolyte solution during operation of the device in the electrodeionization module (1) from the electrodeionization module (1) to the ultrafiltration module (21, 22, 1201, 1202, 1203); wherein the connection piece (3, 10) is devoid of an adjustable pressure-maintaining valve. Via the pressure drop occurring in the ultrafiltration modules (21, 22, 1201, 1202, 1203), these devices build up a counter pressure behind the electrodeionization module (1) which is sufficient to ensure the packing density of the ion exchanger in the electrodeionization module (1).

Abstract: A device for the electrodeionisation of an aqueous electrolyte solution, comprising an electrodeionisation module (1), an ultrafiltration module (21, 22, 1201, 1202, 1203) and a connection piece (3, 10) which connects the electrodeionisation module (1) and the ultrafiltration module (21, 22, 1201, 1202, 1203) such as to be able to guide a diluate produced from said electrolyte solution during operation of said device in said electrodeionisation module (1) from said electrodeionisation module (1) to said ultrafiltration module (21, 22, 1201, 1202, 1203); wherein said connection piece (3, 10) comprises no adjustable pressure-maintaining valve. By means of the pressure drop occurring in the ultrafiltration modules (21, 22, 1201, 1202, 1203) these devices build up a counter pressure behind the electrodeionisation module (1) which is sufficient to ensure the packing density of the ion exchanger in the electrodeionisation module (1).

Abstract: A process for controlled conversion of at least two gases which form ignitable and/or explosive mixtures with one another, in which the gases are absorbed either separately or together in a carrier liquid which is inert in relation to the gases; the carrier liquid with the absorbed gases is fed to a degasser which comprises a closed degassing vessel (2) which comprises at least one feed line for the gas-laden carrier liquid (1) and at least one gas outlet (3) at its upper end, and also one or more drains for the carrier liquid below the feed line for the carrier liquid and in each case connected to a drain pipe (4), and in such a manner that the liquid flow rate in the degassing vessel (2) is less than 0.
