$($c$)$ In a green extraction process of chitin, solid calcium carbonate is the major mincral that need to be removed from shrimp shell waste using a saturated carbon dioxide $(20$ bar$).$ During the process, the calcium carbonate which is in solid form will be converted into calcium bicarbonate, which is soluble in water as shown in the stoichiometry below. However, the reaction is bighly reversible, especially when the concentration of carbon dioxide in the solution decreases. Suggest the type of reactor or reactor design with schematic diagram that can be used to perform this demineralization reaction. Explain why you suggest that reactor design?

$CaC{O}_3(s)+C{O}_2(g)+H_{2}O(l)Ca(HC{O}_3{)}_2(aq)$
