FGD gypsum has a number of decisive advantages compared to natural gypsum which is mined in quarries. It is true that natural material – limestone – is needed to produce FGD gypsum, i.e. in the flue gas desulphurisation systems. All in all, though, this process helps preserve both natural resources and landscapes.
In addition, a metal detector is installed as a back-up to protect the grinding process from malfunction. A double belt conveyor feeds the gypsum into the raw material silo. This technique was chosen because it allows for the inclusion of flue-gas desulphurisation (FGD) gypsum at a later date.

Flue gas desulfurization (FGD) is a very common method for gas claning adopted in a gas processing plant. In this process, the flue gas with acid vapors is scrubbed to remove it as a by-product. Most of the FGD processes use alkali to scrub the flue gas. Many designers of FGD adopt the limestone gypsum process.
