Gypsum is a
mineral found in sedimentary rock formations in a crystalline form known as calcium
sulphate dehydrate CuSo4.2H2O.
Gypsum Storage at large scale is needed since it is one of the prime raw
material in the cement industry and in power plants for FGD plants. In purpose to improve cement’s inherit qualities,
performance and efficiency, a composite gypsum storage solution need to be
followed systematically:
Gypsum handling includes bunkering of gypsum, along with its stacking and reclaiming in a very cautious way. A gypsum handling system adds flexibility and automation to a processing facility helping to ensure that gypsum moves efficiently from one stop to the next and even to a storage and transport. As an aggregate, gypsum can be a difficult material to handle, requiring a system that is robust and able to with stand a rigorous workload. Gypsum is usually stored under well constructed sheds ensuring its storage without deterioration and without exposure to moisture and heat, and away from the direct sun.
For environmentally friendly gypsum storage and production of a best outcome in cement industry, today almost all out-performing cement plants use to store gypsum stockpiles under a strong, durable, eco-friendly and solution-rich gypsum storage sheds and gypsum storage.

Role of gypsum storage system in FGD/ Flue gas desulphurization Unit:
The
resources like coal, petcoke contain a significant amount of sulphur into them.
In many large scale power plants and cement plant (where the raw material is
Coal, petcoke etc), the problems arises from boiler or furnace where large
volumes of So2 accumulation not only deteriorates air quality
of environment but also highly corrosive for handling equipments like stackers,
fans etc.
In
order to extract So2 from flue gas, the mechanism of extraction
employed is known as FGD or Flue Gas Desulphurization. In Flue Gas
Desulphurization, the chemical Techniques are used to exclude sulphur di-oxide
(So2) in exhausted flue gasses from the Furnace/boiler. Some of the
Chemical techniques used for FGD are ‘Wet Scrubing’, ‘Dry Scrubing’, ‘SNOX FGD’
etc.
The output from flue gas desulphurization is synthetic
gypsum, which is carried out under FGDSHEDS. For cement manufacturing, this FGD
storage product or synthetic gypsum is supplied in crushed form for
further fine grinding with cement clinker and has many other commercial
applications in cement industry, bricks manufacturing etc.
