01.01.2017 · The influence of temperature on the ammonium sulfate product efficiency using 10 g of the suspended phosphogypsum in 40 ml of 3% of ammonium sulfate solution (as initiator), 1/4 (S/L) ratio at pH7 is investigated in the range from 25 to 80 °C while the other reaction parameters are kept constant by the addition of ammonium carbonate with 10% excess amount more than the stoichiometric ratio in …
Ammonium Sulfate Production From Gypsum
Dry, powdered ammonium sulfate may be formed by spraying sulfuric acid into a reaction chamber filled with ammonia gas. The heat of reaction evaporates all water present in the system, forming a powdery salt. Approximately 6000M tons were produced in 1981. Ammonium sulfate also is manufactured from gypsum (CaSO 4 ·2H 2 O).
Process for converting FGD gypsum to …
For such a FGD gypsum, the ammonium sulfate product of the present process has less than 0.01 ppm in the ammonium sulfate solutions, which is consistent with commercially available typical granular ammonium sulfate which was also tested. Processes were developed to remove selenium and other possible metal contaminants from FGD gypsum. The processes ensure that the process of the …

Ammonium Sulfate - an overview | …
Ammonium sulfate also is manufactured from gypsum (CaSO 4 ·2H 2 O). In this process, finely divided gypsum is added to a solution of ammonium carbonate causing calcium carbonate precipitates as a solid, leaving ammonium sulfate in the solution: N H 4 2 C O 3 + CaSO 4 → N H 4 2 SO 4 + CaCO 3
8.4 Ammonium Sulfate - US EPA
Ammonium sulfate is produced as a byproduct from the caprolactam oxidation process stream and the rearrangement reaction stream. Synthetic ammonium sulfate is produced by combining anhydrous ammonia and sulfuric acid in a reactor.
ammonium sulphate gypsum process - …
Ammonium sulfate is made by treating ammonia, often as a by-product from coke ovens, with sulfuric acid: 2 NH 3 + H 2 SO 4 → (NH 4) 2 SO 4. A mixture of ammonia gas and water vapor is introduced into a reactor that contains a saturated solution of ammonium sulfate and about 2 … Gypsum, Micro Mix, Water Soluble Fertilizer, Di Ammonium...
Gypsum and its role in trapping ammonia gas
01.08.2014 · The more product blended in the soil, the more ammonia was trapped. The key is to predict the amount of nitrogen per ton of material that will volatilize and then apply enough gypsum to capture that ammonia into a stable ammonium sulfate form. Of course, the end product will contain calcium, ammonium sulfate and other nutrients and carbon.
Ammonium sulfate | (NH4)2SO4 - PubChem
Ammonium sulfate is coproduct in the production of synthetic fiber intermediates, such as caprolactam, acrylonitrile, and methyl methacrylate, and in the production of formic acid and acrylamide. The most important source is the production of caprolactam , which is required for nylon .
