The Pilot Plant Design and Operation Scheme Research on Treatment of Fluoride Flue Gas by Wet Absorption in Electrolytic Aluminium Industry

Abstract:

A survey on the tail gas contained HF of the electrolyzed aluminumindustry was analyzed at first,which included the applications of tail gas treating technology and gas purification devices both at home and abroad.Combining with their professional knowledge and engineering experience,a technical scheme was formed that purifying the tail gas with HF by a new progress,which designed a set of pilot plant about wet hydrogen fluoride absorption, and the optimization of this process scheme. At last,safe operation, equipment design and material selection, automatic control were discussed in this paper. It is worth mentioning that the detection method of by-products and the comprehensive utilization of subsequent product were established.
