Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back The hydrogen fluoride concentration in electrolyte indirect calculation method for a medium-temperature fluorine cell N.V. LIVENTSOVA, O.V. HAGAYTSEVA, S.N. LIVENTSOV, A.A. DENISEVICH There is a method of indirect definition of hydrogen fluoride (HF) concentration in electrolyte for medium-temperature cell presented in the article. HF concentration is calculated as superposition of its average value determined by electrolyte conductivity and dynamic increment determined according to material balance equation. The possibility to use proposed method for the reason to solve a problem of automatic control of HF concentration in electrolyte of industrial cell (СТЭ-20) examined. Key words: fluorine, “medium-temperature” cell, hydrogen fluoride, concentration, indirect method. E-mail: liv_nv@mail.ru Стр. 53-55
