Triple superphosphate is a component of many proprietary fertilisers. It primarily consists of monocalcium phosphate, Ca(H 2 PO 4) 2. It is obtained by treating phosphate rock with phosphoric acid. Many proprietary fertilisers are derived from triple superphosphate, for example by blending with ammonium sulfate and potassium chloride.
A mixture of single superphosphate and triple superphosphate is called double superphosphate. More than 90% of a typical superphosphate fertilizer is water-soluble. The main potassium-based straight fertilizer is muriate of potash (MOP, 95–99% KCl). It is typically available as 0-0-60 or 0-0-62 fertilizer.
[1] [2] The factory complex consists of 2 units of TSP fertilizer producing facility with installed capacity of 1,52,000 MT (Unit-1; 32,000 MT and Unit-2; 1,20,000 MT). [ 3 ] It was founded by East Pakistan Industrial Development Corporation (EPIDC) before the independence of Bangladesh and went into commercial production in 1974. [ 4 ]
Monocalcium phosphate is an inorganic compound with the chemical formula Ca(H 2 PO 4) 2 ("AMCP" or "CMP-A" for anhydrous monocalcium phosphate). It is commonly found as the monohydrate ("MCP" or "MCP-M"), Ca(H 2 PO 4) 2 ·H 2 O.
Phosphate rich organic manure is a type of fertilizer used as an alternative to diammonium phosphate and single super phosphate.. Phosphorus is required by all plants but is limited in soil, creating a problem in agriculture In many areas phosphorus must be added to soil for the extensive plant growth that is desired for crop production.
CSBP commissioned superphosphate and sulphuric acid plants in Kwinana in 1967. The Kwinana Nitrogen Company was established the following year, as a joint venture between CSBP (20 percent) and BP (80 percent). In 1970, CSBP also took over its main rival, Cresco Fertilisers.
The OCP Group (OCP S.A.) (formerly Office Chérifien des Phosphates) is a Moroccan state-owned phosphate rock miner, phosphoric acid manufacturer and fertilizer producer. [2] [3] Founded in 1920, the company has grown to become the world's largest producer of phosphate and phosphate-based products and it is one of the largest phosphate, fertilizer, chemicals, and mineral industrial companies ...
Phosphoric acid is then neutralized to give various phosphate salts, which comprise fertilizers. In the wet process, phosphorus does not undergo redox. [67] About five tons of phosphogypsum waste are generated per ton of phosphoric acid production. Annually, the estimated generation of phosphogypsum worldwide is 100 to 280 Mt. [68]
