摘要： The invention relates to an electrolysis device for halogen gas production from an aqueous alkali halide solution in several plate-type electrolysis cells stacked and arranged side by side, with electrical contacts, each of the cells with a housing consisting of two half-shells made of electrically conductive material, said housing being equipped with devices for feeding electrolytic current and the electrolysis plant reactants and devices for discharging electrolytic current and discharging the electrolysis products, with anodic electrode, cathodic electrode and a membrane arranged therebetween, built-in components being fitted in at least one of the two half-shells and permitting a defined increase in the liquid level and thus minimizing the remaining gas volume accordingly.The built-in components are arranged in such a manner that they form an internal trough parallel to the said membrane and arranged horizontally, an interspace thus being provided between the trough and the membrane and an interspace between the trough and the electrolysis chamber, a part of which is located above the membrane, said trough having at least one opening communicating with the interspace between said trough and the upper side of the electrolytic chamber, and at least one outlet.

摘要： With the help of a method for production of a gaseous diffusion electrode from a silver catalyst on PTFE-substrate, it is endeavored to achieve results which can be reproduced, by avoiding the disadvantages of the state-of-the-art technology, whereby this is achieved in that the porous system of the silver catalyst is filled with a wetted fluid; a dimension-stable solid body with a grain size above that of the silver catalyst is mixed below the silver catalyst; the thus compression-stable mass is shaped into a homogenous catalyst band in a calender; and in a second calender step, an electrically conductive conductor material is imprinted into the catalyst band.

摘要： A process for removing silicon compounds from aqueous NaCl brine includes, first, adjusting a weak brine to a pH value of less than 3 with hydrochloric acid. Iron(III) chloride or other trivalent iron ions are added to the acidified weak brine, the obtained weak brine is then continuously fed to a stirred dissolution vessel which contains undissolved salt in addition to brine. Fresh salt is charged batchwise and intermittently to the dissolution vessel to produce strong brine. The obtained strong brine is fed to a stirred buffer vessel, the pH value in this buffer vessel being maintained at a level ranging from 5 to 8. A strong-brine flow is continuously withdrawn from the buffer vessel and filtered, and the filtrate containing the added iron and silicon is discharged. Also a system for carrying out this process includes: a dissolution vessel for salt, a stirrer in the dissolution vessel, a feed device for batchwise feeding salt to the dissolution vessel, a point for feeding weak brine to the dissolution vessel, points for feeding hydrochloric acid and iron(III) chloride to the weak brine supply line, a buffer vessel for strong brine, a stirrer in the buffer vessel, a flow connection between the dissolution vessel and the buffer vessel, a filter having an outlet for strong brine and a withdrawing device for filter cake, a discharge port and a device for conveying strong brine from the buffer vessel to the filter.
