ccs for the magnesium industry (mineralization)
DESCRIPTION
A lecture given at the Conference Magmin 2012 @ Salzburg. This is the annual conference of the Magnesium industry. CO2 is gaining more attention in this industry. This was the first presentation of this topic for this industry. It gave rather new insights. The reaction between Olivine and CO2 was presented as a example. Partially because of the reaction, but also because this reaction produces Magnesium Carbonate. This is the input stream for this industry. The retrieval of this Magnesium Carbonate is quite cumbersome and expensive. So besides CO2 savings, this could result in economic savings.TRANSCRIPT

Carbon capture and storage
! What is CCS and how could it become a new market for MgO producers? - CCS: A way to lower the CO2 built up
and a way to produce MgCO3 from another source - Yes
! The use of materials in CCS and potential demand levels - Olivine, Serpentine, other materials Demand levels:
although the required scale is immense the current market is currently very small
! How could this provide a new opportunity for your business? Yes, small but growing Assist R&D, follow developments Replace comparable products

Conclusion
A new market is developing in a fast way,
but starts from zero.
