Abstract
In processes for flue gas cleanup, several magnesian and calcareous compounds occur either as parent sorbent materials or as a reaction products. very simple predictive expressions are proposed for estimating the decomposition heats and dissociation pressures of hydroxide, carbonate, sulfite and sulfate of magnesium and calcium at different temperatures. The developed relationships are based on the thermochemical data and experimental results taken from the literature.
