Uses. The primary use of ammonium sulfate is as a fertilizer for alkaline soils.In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth. The main disadvantage to the use of ammonium sulfate is its low nitrogen content relative to ammonium nitrate, which elevates transportation costs.

Ammonium sulfate preparation from phosphogypsum waste . Ammonium sulfate is a mixed fertilizer which contains nitrogen and sulfur nutrients (FAO 2003 Tisdale 2002) The ammonium sulfate provides the ideal solution that has a quick sulfate release tied in with the season-long availability of degradable sulfur (Hoeft et al 1985 Dudal 2002)
Ammonium sulfate is an inorganic sulfate salt obtained by reaction of sulfuric acid with two equivalents of ammonia.A high-melting (decomposes above 280℃) white solid which is very soluble in water (70.6 g/100 g water at 0℃; 103.8 g/100 g water at 100℃), it is widely used as a fertilizer for alkaline soils. It has a role as a fertilizer.
Jun 15, 2018· Phosphogypsum (PG) as a low-cost calcium resource was used to prepare nano-CaCO 3 in a three-phase system by reactions. Based on the population balance equation, nano-CaCO 3 crystal nucleation and growth model in the gas (CO 2)-liquid (NH 3 ·H 2 O)-solid (CaSO 4) three-phase system was established.The crystallization kinetic model of nano-CaCO 3 in CO 2-NH 3 ·H 2 O-CaSO 4 .

Nov 10, 2009· In extending these studies to ammonium sulfate solutions, we report the value of γ e as defined by Eq. 2.Here, 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.
The invention discloses a process for preparing ammonia by utilizing calcium oxide. The process is simple, has low investment, is energy-saving and is very suitable for enterprises which need to be supplied with a small amount of ammonia. The ammonia can be prepared by respectively adopting a feeding and cutting process and a continuous process.
