MgO exhibits different properties depending on the source and calcination conditions used during its production. The main parameters used to assess the characteristics of MgO are its reactivity, SSA, crystallite size, crystal structure, density, agglomeration ratio (i.e., the ratio of the primary particle size to the crystallite size), pore structure, total porosity, and morphology (Li, 2013

If the calcination is done in closed retorts, a considerable quantity of ammonia is obtained. The cinder is lixiviated, and on evaporation, the solution yields, first, chlorides and sulphates of potassium and sodium, and finally a very pure potash, which averages a little less than
The cost for larger plants (224,000-235,OOOscfm) is estimated to be 82.6-2.9 million in battery limits. The desulfurization cost for a plant to treat 100,000-150,OOOscfm gas from an oil-fired boiler is estimated at $0.67-0.88/bl of oil containing 2.5-3.0$ sulfur, including depreciation and credit on gypsum at $6/t.

Abstract: An air pollution control system 10A according to the present invention includes: a boiler 11 that burns fuel; NOx removal equipment 12 that decomposes nitrogen oxides in flue gas 25 discharged from the boiler 11; a desulfurizer 15 that causes sulfur oxides in the flue gas 25 having passed through the NOx removal equipment 12 to be absorbed by an absorbent, thereby reducing sulfur
2021-1-29 · Advantages: gypsum calcination in kilns (drying drums) can be carried out by means of direct contact with hot gases formed after burning of fuel, the fuel can be solid, liquid or gas; after grinding in the mill the material composition of the product is conditioned by transfer of underburnt and overburnt material to semihydrate.
