anhydrous ammonia and sulfuric acid in a reactor. 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 sulfate manufacturing for each of the 3 primary commercial processes. After formation of the ammonium sulfate solution

Gypsum Processing - FEECO International Inc.

Gypsum can be a difficult material to process, from its variability, to its tendency to harden into a cement-like form, and its abrasive nature. For this reason, choosing processing solutions that are heavy-duty and designed around the unique characteristics of the gypsum sample to be processed will offer the best results.

Preparation of ammonium sulfate - STEM

Preparation of ammonium sulfate Student worksheet 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 by-product of

Ammonium sulphate - SlideShare

Now proper proportion of finely ground gypsum or anhydrite is fed into the aqueous solution of ammonium carbonate in large reactor, whereby calcium carbonate is precipitated gradually as a result of double decomposition. Reactions of ammonium carbonate and gypsum solutions are carried out in a series of wooden vessels or mild steel vessels having steam coils and agitators to give a total

Ammonium Sulfate – AMMONIA INDUSTRY

Ammonia production began at Hopewell in 1928, at which time it was the largest ammonia plant in the US. Today, using a plant built in 1965, ammonia is upgraded to caprolactam, for nylon; byproduct ammonium sulfate is sold as fertilizer. Unfortunately, the Hopewell site has a long history as an environmental disaster zone. In October 2016, Honeywell's resins and chemicals division was spun-off

11.16 Gypsum Manufacturing - US EPA

11.16 Gypsum Manufacturing 11.16.1 Process Description1-2 Gypsum is calcium sulfate dihydrate (CaSO4 2H2O), a white or gray naturally occurring mineral. Raw gypsum ore is processed into a variety of products such as a portland cement additive, soil conditioner, industrial and building plasters, and gypsum wallboard. To produce plasters or wallboard, gypsum must be partially dehydrated or

Making Gypsum Board – Gypsum Association

To produce gypsum board, crushed natural gypsum or synthetic gypsum is heated or calcined to dehydrate the feedstock. Next the calcined gypsum is mixed with water and additives to form a slurry which is fed between continuous layers of recycled paper on a long board machine.
