Jun 15, 2018· Phosphogypsum (PG) as a lowcost calcium resource was used to prepare nanoCaCO 3 in a threephase system by reactions. Based on the population balance equation, nanoCaCO 3 crystal nucleation and growth model in the gas (CO 2)liquid (NH 3 ·H 2 O)solid (CaSO 4) threephase system was crystallization kinetic model of nanoCaCO 3 in CO 2NH 3 ·H 2 OCaSO 4 .

Ammonium sulfate is well known for the first order phase transition which occurs upon cooling to a Ferroelectric crystal. Ammonium sulfate is made by treating ammonia, often as a byproduct from cokeovens, with sulfuric acid2 . Ammonium sulfate also is manufactured from gypsum (CaSO4·2H2O).
Feb 01, 2018· This study aimed to investigate the performance of phosphogypsum and calcium magnesium phosphate fertilizer for nitrogen conservation during composting. Pig manure was used as the raw composting material with cornstalk as the bulking agent. Emissions of nitrogen gases (·NH 3 and N 2 O) were evaluated during composting. Key physicochemical ...

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.

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.
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 seasonlong availability of degradable sulfur (Hoeft et al 1985 Dudal 2002)
