Carbonation and Captation of CO2: optimisation of a feasibilitry demonstration

In this work, we are interested in the sources of raw materials for mineral carbonation as well as the valorization of the products resulting from this carbonation. To achieve carbonation of waste and to obtain a valuable product we need carbonatable materials such as Fe, Mg, Mn, Ca: it is necessary to seek these compounds in the waste considered. We will focus on particular sources of waste, the residues of cement industries, bottom ash (steel mills, incineration of household waste) or building deconstruction residues. The objective of this paper is to describe the functional specifications of a carbonation unit that is both flexible enough to treat a wide variety of these materials, and compact enough to allow it to be moved from one source to another. These specifications will concern two different uses of this mobile unit: that of initial feasibility demonstration, and those corresponding to its current operation.
