Get MANUFACTURE OF AMMONIUM SULFATE FERTILIZER FROM GYPSUM-RICH BY- PRODUCT OF FLUE GAS DESULFURIZATION

Ammonium sulfate also is manufactured from gypsum (CaSO4·2H2O). Finely divided gypsum is added to an ammonium carbonate solution. Calcium carbonate precipitates as a solid, leaving ammonium sulfate in the solution.

Synthetic ammonium sulfate is produced by combining anhydrous ammonia and sulfuric acid in a reactor. Coke oven byproduct ammonium sulfate is produced by reacting the ammonia recovered from coke oven offgas with sulfuric acid.

AMMONIUM SULFATE IS MANUFACTURED FROM GYPSUM BY A CONTINUOUS PROCESS IN WHICH AN AQUEOUS FLOW OF MATERIAL IS CONTINOUSLY RECYCLED ALONG A PREDETERMINED CLOSED CIRCUIT DEFINED BY A CONDUIT AND A WIDER VALLEL CONNECTED IN SERIES.

Flue gas desulfurisation gypsum (FGD Gypsum) is a solid residue recovered from the gas treatment process for sulfur dioxide removal using lime or limestone.

Flue gas desulfurization gypsum (FGDG) is an industrial by-product generated during the flue gas desulfurization process in coal-fired power plants. Due to its abundance, chemical and physical properties, FGDG has been used in several beneficial applications.

The material is then dewatered and processed; the end product is a consistent, finely divided powder. This process is known as flue gas desulfurization (FGD), and the gypsum produced is known as FGD gypsum. The term FGD gypsum is the name most often used by generators of the material.

Flue gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO2) from flue gases produced from industrial combustion at petrol refineries, chemical manufacturing industries, mineral ore processing plants, and power stations to name a few.

Flue gas desulphurization (FGD) materials such as gypsum and hannebachite are the solid phases remaining after lime based materials have been used to scrub off-gases of a coal burning power plant.
