OREANDA-NEWS. November 22, 2010. Commissioning of the two-filter presses and 4 slurry clarifiers at the Black Filtration stage at JSC Crimea TITAN has started. It is the successful experience of the Moore filters in TITAN-2 workshop at the white filtration stage that set the impulse to further development and perfecting of TiO2 production process. In the year 2005 technicians and management of JSC Crimea TITAN made a decision to replace out-of-date drum vacuum-filters with the modern fully automated filter-presses.

Total cost of the equipment and installation works amounted to USD 18.5 mln. Start-up of two-filter presses at the post-treatment stage allowed workshop production capacity to be increased from 40 thsn.t/year to 60 thsn.t/year and improved the process of leaching of titanium dioxide suspension from water-soluble salts. Modernization of the black filtration site in the Titan-2 workshop will allow to decrease acid waste amount at this stage by 70-80%, wood flour consumption by 85-90%, and energy resources expenditure (gas, steam, power) by 40-50%. Switching over to fully automated black filtration process will eliminate human factor impact as much as possible which will improve consistency of quality of black liquor solutions, and increase site capacity with drastic reduction of the amount of vapors released in the working area.

By the end of this year titanium dioxide production capacity is expected to reach 105 thsn.t to become the highest in the history of the factory (the previous record was reached in 2008 – 90289 tons).
