Ammonium sulfate is an inorganic sulfate salt obtained by reaction of sulfuric acid with two equivalents of highmelting (decomposes above 280℃) white solid which is very soluble in water ( g/100 g water at 0℃; g/100 g water at 100℃), it is widely used as a fertilizer for alkaline soils. It has a role as a fertilizer.

The mereseberg process is used a waste of phosphogypsum withammonium carbonate to produce ammonium sulfate as a main product andcalcium carbonate as a byproduct. It is a process could be used as a successfulmethod in phosphate industry (ALQauim).The flow diagram is drawn to illustratethe mersberg process then material balance is done.
Nov 10, 2009· In extending these studies to ammonium sulfate solutions, we report the value of γ e as defined by Eq., however, p sat is the equilibrium vapor pressure of the solution, rather than that of pure water. Because this vapor pressure is ≈13% lower than that of pure water, the maximum theoretical evaporation rate for the solution is lower than that of pure water.
