AMMONIUM SULFATE FERTILIZER PRODUCTION LINE Ammonium sulfate [(NH4)2 SO4] was one of the first and most widely used nitrogen (N) fertilizers for crop production. It is also used for many applications in the chemical, wood pulp, textile, and pharmaceutical industries.

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).

from five to 10 million tons annually of new ammonium sulfate production for the fertilizer market is anticipated. Goals and Objectives The overall goal of this project is to assess the technical and economic feasibility for producing commercial-grade ammonium sulfate fertilizer from FGD-gypsum. The

Nov 01, 2015· Analysis of ammonium sulfate is also discussed in Chapter 5-2.2, by description of the Kjeldahl digestion method, by distillation or diffusion extraction and by conversion of ammonium salts (e.g. ammonium sulfate) into N 2 gas. Since ammonium sulfate was basically an inorganic compound, analysis of ammonium sulfate was included in this chapter.

V. Evaluate the impact of continued use of FGD-gypsum-derived ammonium sulfate on soil chemical properties. VI. Establish a process flow sheet for the production of ammonium sulfate from FGD gypsum and evaluate the production costs and the market potential for the product. This project is a cooperative effort among the ISGS, UIUC, AUiedSignal, SE-ME,

Production. 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. Ammonium sulfate also is manufactured from gypsum (CaSO 4 ·2H 2 O). Finely divided gypsum is added to an ammonium carbonate solution.
