    摘要: Processes, methods, system and uses in relation to chemical sequestration of carbon dioxide from a carbon dioxide containing gas by carbonation of an alkaline earth metal containing material. The carbon dioxide containing gas is contacted with an aqueous slurry in a carbonation unit for carbonation of at least a portion of the alkaline earth metal to produce a carbon dioxide depleted gas and a carbonate loaded slurry which is substantially exempt of precipitated alkaline earth. metal carbonates. The carbonate loaded slurry is then separated into an aqueous phase and a solid phase; and the aqueous phase is supplied to a precipitation unit for precipitating alkaline earth metal carbonates. The carbonation stage may be performed at a carbonation temperature between about 10° C. and about 40° C. and a carbonation pressure between about 1 bar and about 20 bars. The solid phase may be recycled to the carbonation stage.

    摘要: There is described a passive variable emittance device comprising: a substrate having a receiving surface adapted to reflect radiations having a given wavelength; an intermediary layer deposited on the receiving surface of the substrate and being substantially transparent to the radiations having the given wavelength; and a thermochromic layer deposited on top of the intermediary layer, the thermochromic layer being substantially transparent to the radiations having the given wavelength for a first temperature below a given transition temperature, and presenting both reflection and absorption for the radiations for a second temperature above the given transition temperature, a total optical thickness for the intermediary and thermochromic layers being substantially equal to one quarter of the given wavelength so that radiations reflected by the thermochromic layer at the second temperature destructively interfere with radiations transmitted by the thermochromic and intermediary layers and reflected by the substrate in order to obtain a first emittance for the passive variable emittance device at the second temperature being greater than a second emittance for the passive variable emittance device at the first temperature.
