9. Batrec’s Catalyst Recycling business
 decontamination of the Hg guards to enable a subsequent Cu recycling
waste reception (drums or CHEP bins)
sampling
storage
thermal decontamination
sampling & Hg reporting
forwarding of the material to Nickelhütte for Cu recovery

10. Batrec’s part in Puracare – sampling

11. Batrec’s part in Puracare – storage
storage for 18 containers
IR detection in front of the boxes

12. Batrec’s part in Puracare – thermal decontamination

13. Batrec’s Catalyst Recycling business – chemical reactions
thermal desorption in furnace (850 °C) HgS  Hg + S
post-combustion chamber (1100 °C) S + O2  SO2
lime milk washer SO2 + CaO + ½ O2  CaSO4

14. Batrec’s Catalyst Recycling business – thermal decontamination – charging of catalysts

15. Batrec’s Catalyst Recycling business – thermal decontamination – the furnace

16. Batrec’s Catalyst Recycling business – thermal decontamination – the furnace

17. Batrec’s Catalyst Recycling business – thermal decontamination – the furnace

18. Batrec’s part in Puracare – thermal decontamination – post-combustion chamber

19. Batrec’s part in Puracare – thermal decontamination – scrubbers

20. Batrec’s Catalyst Recycling business – thermal decontamination – waste water treatment

21. recent developments – Hg stabilization
motivation for Batrec  offer one hand solution to JM and other customers that require Hg stabilization (no subcontractors needed for stabilization of Hg)
technical approach Hg + S = HgS (red or black) - liquid S + liquid Hg react to HgS - very toxic Hg is transformed into non toxic HgS - produced stone (50 % S, 50 % Hg) can be safely stored in German salt mines

22. recent developments – Hg stabilization
what is the idea behind stabilization to HgS?
the most stable mercury compound
the most insoluble metallic-sulphide compound
the natural mineral form known as cinnabar
alternatives
amalgamation

23. BATREC’s business areas
Battery Recycling
Hg recycling
Decontamination of Hg-guards
Reactivation of activated carbon 23

24. Hg Recycling Capacity: ca. 300 t/year of waste containing Hg
3 distillation units (2 retorts, 1 rotary kiln)
Treatment of all types of Hg waste
Production of Hg with a purity of %

25. examples for Hg containing wastes treated at Batrec
lamps (Hg vapour pressure )
button cells, Hg cells
relays, switches
dental waste (amalgams, centrifuges,…)
thermometers, blood pressure meters
Hg containing chemicals (Hg2Cl2, HgO, HgS, Hg,...)
calomel (solutions) from Cu + Zn metallurgy
concrete & soils & slurries contaminated with Hg
Hg containing solutions
activated carbon, coke and graphite containing Hg

27. Hg removal from Hg centre off gas
distillation at 600 – 700 °C (Hg vaporises at °C)
distillation under negative pressure to avoid Hg emissions
Hg is removed by a 3 scrubber system
the washers are actively cooled to <5°C in order to condense the Hg
remaining traces of Hg are removed by a final activated carbon filter, filled with S impregnated carbon 27 27

Battery Recycling
Hg recycling
Decontamination of Hg-guards
Reactivation of activated carbon 31

32. Adsorbent Recycling Decontamination of Hg guards coming from natural gas production Reactivation of activated carbon
Installation running since November 2011
1.000T capacity for the treatment of catalysts coming from the gas extraction industry („mercury guards“)
3.000T capacity for the reactivation of activated carbon
others wastes containing Hg:
powder carbon.
contaminated soil with Hg and/or Dioxins.
Hg containing waste with organic compounds.

33. Treatment of spent active carbon
Regeneration Treatment at low temperature at 180°C
Reactivation Treatment at high temperature (up to 850°C) that gives back to the carbon its original adsorption capacity
Thermal recycling
Carbon’s combustion

34. Reactivation of activated carbon by BATREC
Reactivation of granular active carbon coming from water treatment
Reactivation of extruded active carbon coming from gas treatment plants.
First trials have been made to treat powder active carbon coming the adsorption of suspended pollutants.
During reactivation
Thermal desorption of the pollutants at a temperature of 700 – 750°C
Thermal destruction of the pollutants in the post-combustion chamber.
The original adsorption of the carbon is renewed (iodine index)
Added value for customers
Lower purchasing costs for «fresh» carbon (1 – 5 Euros/kg)
Lower disposal treatment costs
Reduction CO2 emissions
