The origin of syngenite in black crusts on the limestone

Apr 01, 2012 Black crusts formed on limestone built into the Kings Gate represent the most important process in stone deterioration that is occurring in this part of the monumental complex of the Belgrade Fortress Serbia. Of special importance is the association of salts namely gypsum and syngenite.

INVESTIGATION OF ORGANIC DESULFURIZATION

INVESTIGATION OF ORGANIC DESULFURIZATION

The limestone-gypsum wet flue gas desulfur-ization WFGD process is the most widely used desulfurization technology in Chinese coal-power plants, for removing acidic compounds SO2, HCl and HF from flue gases 1-3. In WFGD system, SO2 gases are absorbed by the limestone slurry, and SO2 com-bines with H2O to produce HSO3-ions. In the slurry

Limestonegypsum flue gas desulfurization process

The whole process of the limestone lime-gypsum flue gas desulfurization of the present invention will be illustrated by way of FIG. 1. Referring to FIG. 1, a flue gas 1 containing sulfur oxides is passed through a gas heater 3 and led into a cooling tower 5 where dust contained in the flue gas is removed and at the same time the gas is cooled.

Flow and density measurement of lime slurry in flue gas

The FGD units use the limestonegypsum wet scrubbing process. This involves lime slurry prepared in an agitated reactor that is pumped to the top of the absorption tower, where it is sprayed into the rising flue gas by nozzles. As a result, SO x in the flue gas stream is washed out absorbed. Subsequently, a suspension of gypsum as a reacting ...

Gypsum is a non-metallic mineral, found in rock form. It is composed of 79.1 calcium sulphate and 20.9 water, by weight. Chemists call it Hydrous Calcium Sulphate, and as there is one molecule of calcium sulphate combined with two molecules of water. It has the chemical formula CaSO 4 2H 2 0. By volume this works out to nearly 50 water in ...

5 gypsum. The ternary blended cement took less time to reach the same fineness level as OPC due to soft pozzolana and high grade lime stone, indi-cating that intergrinding may reduce overall power consumption. Blended cem-ent production using natural pozzolana and limestone may reduce the energy consumption and greenhouse gas emissions.
