3V TECH technology for Ferric Chloride production is based on 3V TECH glass-lined reactors, high performance equipment for process requirements. Ferric Chloride can be obtained from different raw materials: Ferrous Oxide, Ferric Oxide and Iron Scraps.Ferric Chloride 40% from Ferrous Oxide, scales from rolling-mil process, is obtained through attack with 32% HCl followed by chlorination that assure complete conversion to Ferric Chloride.Ferric Chloride 40% from Ferric Oxide, by-product of steel mills, is obtained by simple reaction with 32% HCl.Ferric Chloride 40% from Iron Scraps is obtained by attack of ferric chloride with iron into a dissolution vessel. The resulting ferrous chloride solution is filtered and oxidized to ferric chloride in the chlorination section by chlorine gas.
Ferric Chloride 40% solution is used as a flocculant in sewage treatment and drinking water production. When small quantities of ferric chloride are added to the raw water, iron(III) hydroxide precipitates and adsorbs finely divided solids and colloids.
The plant can be design to operate with all kind of raw materials previously mentioned.Depending on raw materials, different sections and reactors are adopted.
Target is to obtain a solution with Fe2Cl3 : 40 ± 0,5% Fe 3+ content : 13,78 ± 0,01%Fe 2+ content : 0,30 ± 0,1%
Ferric Chloride plant normally consist of following sections:
Utilities such as steam, cooling water, instrumentation air, storage tanks, civil works, local environmental permission, sewage system and sludge handling
Downstream plant of hydrochloric and chlorine production plants
