摘要： The invention concerns a fluorine gas manufacturing plant wherein F 2 is manufactured by the electrolysis of KF/HF compositions. The plant comprises skid modules for: FIF storage, the electrolytic cells, storage and purification of the manufactured F 2 raw gas, for fluorine gas delivery including a single buffer tank or multiple storage units, scrubbers to provide purified waste gas, for providing cooling water circuits, analysis, electrical rectifiers, an electrical substation with transformers and emergency supply, and for utilities including a control room with laboratory and a rest room for the personnel. The advantage of the skids is that they can be separately manufactured in workshops, tested, transported to the facility and assembled there. A great advantage is the safety aspect, a reliable F 2 production for 24 h and 7 days a week of high purity F 2 .

摘要： Elemental fluorine is often manufactured electrochemically from a solution of KF in hydrogen fluoride and contains varying amounts of entrained electrolyte salt in solid form as impurity. The invention concerns a process for the purification of such impure elemental fluorine by contact with liquid hydrogen fluoride, e.g. in a jet gas scrubber or by bubbling the raw fluorine through liquid hydrogen fluoride. After this purification step, any entrained hydrogen fluoride is removed by adsorption, condensing it out or both. After passing through a filter with very small pores, the purified fluorine is especially suited for the semiconductor industry as etching gas or as chamber cleaning gas in the manufacture of semiconductors, TFTs and solar cells, or for the manufacture of micro-electromechanical systems ("MEMS").
摘要翻译：元素氟通常由KF在氟化氢中的溶液电化学制造，并含有不同量的作为杂质的固体形式的夹带电解质盐。本发明涉及通过与液体氟化氢接触来纯化这种不纯的元素氟的方法，例如，在喷气式气体洗涤器中或通过液态氟化氢鼓泡原料氟。在该纯化步骤之后，通过吸附除去夹带的氟化氢，将其冷凝出来或两者。在通过具有非常小的孔的过滤器之后，纯化的氟特别适用于半导体工业，作为半导体，TFT和太阳能电池的制造中的蚀刻气体或室清洁气体，或者用于制造微机电系统（“ MEMS“）。

摘要： Elemental fluorine is used as etching agent for the manufacture of electronic devices, i.a., semiconductor devices, micro-electromechanical devices, thin film transistors, flat panel displays and solar panels, and as chamber cleaning agent mainly for PECVD apparatus. For this purpose, fluorine often is produced on-site. The invention provides a process wherein the contamination of the elemental fluorine with gaseous impurities, such as air or moisture, is prevented by producing it on site and delivering it to the point of use under a pressure higher than ambient pressure.
