摘要： The invention pertains to a method for supplying hydrogen fluoride as feed material to an electrolytic cell (electrolyzer) for (electrolytically) generating elemental fluorine from a molten salt electrolyte, which comprises transferring hydrogen fluoride (HF) from (a) a hydrogen fluoride supply unit via (b) a hydrogen fluoride supply line to (c) to the electrolytic cell, wherein the required amount of hydrogen fluoride feed for a defined fluorine production capacity is fed into the electrolytic cell, preferably as gaseous HF, with a substantially lower HF feeding quantity per hour (kg/h) over a prolonged feeding interval compared to a full (maximum) HF feeding capacity of 80 kg/h of the supply line and the related short full HF feeding interval, as in hitherto conventional methods. In another aspect the invention also concerns an electrolytic cell for the generation of elemental fluorine by the electrolysis of a molten HF adduct of KF, in which the HF supply line is adapted to the method for supplying hydrogen fluoride as feed material according to the invention.

摘要： The invention pertains to a method of measuring and/or controlling the electrolytic bath liquid level in an electrolysis cell for the generation of fluorine gas having an anode chamber and a cathode chamber separated from each other by a partition wall for generating fluorine gas by electrolyzing an electrolytic bath (electrolyte) comprising a hydrogen fluoride-containing mixed molten salt of an HF adduct of KF, wherein the method comprises the steps of (a) detecting the pressure in at least one of the anode chamber and the cathode chamber during generation of fluorine gas by pressure sensing means comprising a tube (liquid level sensing tube) reaching (submersing) into the electrolytic bath (electrolyte), and, preferably, (b) supplying through the tube of the pressure sensing means an effective amount of hydrogen fluoride to thereby remove and/or prevent plugging caused by potentially crystallized HF adduct of KF in the tube of the pressure sensing means at any time and/or during measuring and/or controlling the electrolytic bath (electrolyte) liquid level in the anode chamber and/or cathode chamber.

摘要： The present invention concerns an electrolytic process for the manufacture of fluorine comprising the electrolysis of an adduct of KF and HF wherein the electrolytic process is monitored by a thermographic camera, and an apparatus therefor. The method of monitoring the electrolytic process of fluorine production using conventional electrolytic cells, provides the possibility to automate the HF addition by reading the electrolyte level continuously. Additionally malfunctions like external fires (H 2 + O 2 recombination), internal H 2 + F 2 recombination due to broken partition walls, insufficient cooling, non optimal electrical connections can easily be detected, which leads to enhanced security of the process and less energy consumption.
