8.4 Ammonium Sulfate 8.4.1 General1-2 Ammonium sulfate ([NH4]2SO4) is commonly used as a fertilizer. In 1991, U. S. facilities produced about 2.7 million megagrams (Mg) (3 million tons) of ammonium sulfate in about 35 plants. Production rates at these plants range from 1.8 to 360 Mg (2 to 400 tons) per year. 8.4.2 Process Description1
Aug 26, 2017 Liquid ammonia and CO2 is absorbed in absorbing tower and form ammonium carbonate at the pressure of about 2.1kg/cm2. The prepared liquor strength corresponds to approximately 170gms of ammonia and 225gms of CO2 per liter.

how to make ammonium sulfate from gypsum. 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 season-long availability of degradable sulfur (Hoeft et al, 1985, Dudal, 2002)
Phosphogypsum (CaSO4 2H2O, PG) waste is produced in large amounts during phosphoric acid (H3PO4) production. Minor quantities are utilized in construction or agriculture, while most of the material is stockpiled, creating an environmental challenge to prevent pollution of natural waters. In principle, the gypsum waste could be used to capture several hundred megatonnes of carbon dioxide …

Jan 01, 2017 1. Introduction. Ammonium sulfate is found in the most everyday applications because of their unique chemical and physical properties. Ammonium sulfate is used in the agricultural fertilizer as a source of nitrogen and sulfur for plant nutrients (Schwenke & McMullen, 2009).Ammonium sulfate is a mixed fertilizer which contains nitrogen and sulfur nutrients (FAO, 2003, Tisdale, 2002).
Ammonium sulphate is produced from many sources. This paper concentrates on ifs production as a so-called co-product or by-product as a result of other industrial endeavours. In order to define the scope for this review, it is important first of all to give some brief background and attempt some definition of the terms co-product and by-product.
Gypsum block Wikipedia. Manufacture. A gypsum block is made of gypsum plaster and water. The manufacturing process is automated at production plants where raw gypsum CaSO 4 1832H 2 O is ground and dried, then heated to remove threequarters of the bound water and thus transformed into calcium sulfate hemihydrate CaSO 4 183189H 2 O, also known as gypsum plaster, stucco, calcined gypsum …
