摘要： In this electrolysis apparatus for the preparation of chlorine from aqueous alkali halide solutions, which comprises at least one electrolytic cell, the anode and gas diffusion cathode are disposed horizontally and separated from each other by a partition in a housing consisting of two half shells and are connected mechanically and in an electrically conducting manner by means of their edges to the respective half shells. In addition, the cathode is connected in a liquid-tight manner to its half shell and is supported by a current supply and distribution device. The partition is clamped between a circumferential seal between the edges of the half shell and a frame and is supported on a spacer which rests on the cathode and is held by the frame. The frame contains an inlet and outlet for the catholyte.

摘要： In this electrolysis apparatus, the anode and the gas diffusion cathode are arranged to be separated from one another by means of a partition. At least one element (6) which has the form of a twin trough is located between two half-shells (1, 2) which are located at the ends and of which one carries an anode (4) and the second carries a cathode (5). This twin trough is formed by a common plate (7) and a lateral wall (8), the height of which is divided by the plate and the edges of which are provided with flanges (9, 10). The anode (4) and the cathode (5) are electrically conductively connected to the wall (8) and to struts (13) which protrude vertically from the plate on both sides. In order to form a cavity (16) between the partition (14) and the cathode (5), a sealing element is arranged between these two.

摘要： In the electrolysis of an aqueous alkali metal chloride solution, a mixture of anolyte and steam-saturated gaseous chlorine is formed in the anode space of the electrolytic cell. According to the invention, the process is carried out under a pressure of at least 8 bars. For workup, the anolyte is at first separated from the steam-saturated gaseous chlorine which is then liquefied under a pressure of at least 8 bars by cooling. In the course of cooling there is obtained a condensate which consists of a liquid water-saturated chlorine phase and a liquid chlorine-saturated water phase. The temperature of said condensate is not to fall below 28.degree. C. during cooling. Finally, the light-weight water phase is separated from the chlorine phase having a heavier specific weight.

摘要： An electrolyzer for the production of chlorine from an aqueous alkaline halide solution includes a plurality of electrolysis cells each having a housing of two half-shells. The bottom side of each of the half-shells is in a plane parallel to a plane of an adjacent anode or cathode, the space between the bottom side and the anode or the cathode being provided with framework-pattern metallic reinforcements. Each bottom side has one or more contact strips attached to its outer surface which are arranged in a congruent position to the contact strips on the bottom side of the adjacent electrolysis cell, and extend over the length or width of the cell. The contact strips are aligned with and connected by electrically conducting means to part of the framework-pattern reinforcements and the unperforated sections of the adjacent anode or cathode. The two half-shells and a membrane partition wall are assembled to form an electrolysis cell sealed by two gaskets.

摘要： The electrolysis of aqueous alkali metal chloride solutions under pressure has already been carried out. In accordance with the invention there is applied a pressure of at least 8 bars in the anode space for such an electrolysis, as well as a special process for the work-up of the products of the anode space. The mixture of gas and anolyte leaving the anode space is at first mechanically separated, and the anolyte is then depressurized into a stripping column. In the course of this process a dechlorination and cooling of the anolyte are taking place. The anolyte is to enter the pressure release vessel (stripping column) with a temperature being above the boiling point of the anolyte at atmospheric pressure. The reduced pressure is to be between 2 bars and atmospheric pressure. By means of these measures it may be ensured that the anolyte in the stripping column reaches boiling point. Finally the chlorine set free in the pressure release operation is separated from the anolyte.
