Ammonium nitrate is made by the reaction of ammonia with nitric acid in water followed by careful evaporation of the water to yield a solid element: NH 3 + HNO 3 → NH 4 NO 3 Ammonia is usually derived from atmospheric nitrogen and nitric acid is prepared from the combustion of ammonia.
Making ammonium sulfate . Ammonium sulfate is a complex fertiliser.This simple salt is a source of two nutrients nitrogen – and sulfur. About 90 percent of ammonium sulfate is produced by 3 different processes: • as a by-product from the production of caprolactam ; • synthetically by reacting anhydrous ammonia and sulfuric acid;

As a result, caprolactam producers have long sought to develop technology that reduces or otherwise removes co-production of ammonium sulfate. There has been some success in achieving this goal. At the turn of the 21st century three major technologies arose for improving the process. EniChem commercialized a process that avoided the …

which contains sulfur: ammonium sulfate. Ammonium sulfate feeds sulfur and nitrogen to the soil. With its colloidal components, the fertilizer binds to clay particles in the soil, ensuring a long-term supply of nutrients. Ammonium sulfate is thus perfect for plants with a long growth period and in areas with high rainfall.
Coke oven byproduct ammonium sulfate is produced by reacting the ammonia recovered from coke oven offgas with sulfuric acid. Figure 8.4-1 is a diagram of typical ammonium …
Ammonia is processed into downstream fertilizer products before being applied to the soil. These products include urea, ammonium nitrates, ammonium sulfate, ammonium phosphates, and nitrogen solutions. Consumption of ammonia in industrial applications is projected to grow slightly faster than fertilizer use during the forecast period.
After formation of the ammonium sulfate solution, manufacturing operations of each process are similar. Ammonium sulfate crystals are formed by circulating the ammonium sulfate liquor through an evaporator. Evaporation of the water thickens the solution. Ammonium sulfate crystals are separated from the liquor in a centrifuge.
Ammonium sulfate has been produced for more than 150 years. Initially, it was made from ammonia released during manufacturing coal gas (used to illuminate cities) or from coal coke used to produce steel. Today, manufacturers make it by reacting sulfuric acid with heated ammonia (see process schemes below).
tom processing equipment, process design and feasibility testing, and improved approaches to fertilizer granulation, including the production of ammonium sulfate …
Costs for constructing and operating a conceptual plant based on a proposed process that converts flue gas desulfurization (FGD)-gypsum to ammonium sulfate fertilizer has been calculated and used to estimate a market price for the product. The average market price of granular ammonium sulfate ($138/ton) exceeds the rough estimated cost of …
The primary production methods of ammonium sulfate fertilizer are: By-product recovery from production of caprolactam, a feedstock for production of Nylon 6 polymer Reaction of coke oven off-gasses with sulfuric acid and Intentional synthesis by reacting anhydrous ammonia and sulfuric acid.
Ammonium Sulfate Fertilizer. Ammonium Sulfate, (NH 4) 2 SO 4, is an inorganic salt which is an important source of nitrogen (N) and sulfur (S) for crop nutrition. It can be used as a directly applied fertilizer as well as a component of NPK blends and compound fertilizers. Its nutrient analysis designation for N, P, K and S is 0-0-21-24S.
