| titleOfInvention | A method for producing a TiO2 dye according to a sulphation process and an oven for carrying out this process |
| abstract | Process for producing dyes and TiO 2 by dissolving raw materialsncontaining titanium in sulfuric acid, making a solutionnof titanium sulfate containing metal sulfate, by hydrolysisnof this titanyl sulfate, by separating the titanium dioxide hydrate fromnsulfuric acid containing metallic sulphate by filtration, optionallynby bleaching titanium dioxide hydrate with a reducing agent innacidic solution, by mixing titanium dioxide hydrate withnadditional chemicals and calcination of the oxide hydratentitanium dye to TiO2, the essence of which is likenthe starting material for calcination uses an oxide hydratentitanium TiO2, which has less than 3 kg of sulfate ions pern1 ton of TiO2 after alkaline hydroxide treatment and after washingnalkali metal sulfate, the filter cake containing the alkali metal sulfatentitanium dioxide hydrate and additional chemicals are dried innsolids dryer at 100 to 300 ° C and dried solidnis subsequently calcined in a calcining furnace at temperatures above 1100n° C (solids temperature) to TiO2 dye and exhaust gases tonDust removal, calcining furnace for production of TiO2 dyesndried titanium dioxide hydrate which is in shapenrotary kilns, wherein the ratios of their diameter are innranging from 5 to 10. |
