Ammonium sulfate is an inorganic salt with a number of commercial uses. The most common use is as a soil fertilizer. It contains 21% nitrogen and 24% sulfur by weight. Ammonium sulfate also is manufactured from gypsum (CaSO 4 ·2H 2 O). Finely divided gypsum is added to an ammonium carbonate solution. ammonium sulphate gypsum process diagram
Mar 23, 2016· We evaluated the chemical sequestration of carbon dioxide into the phosphogypsum from the Lowveld region of South Africa. The phosphogypsum was converted to saleable ammonium sulphate and precipitated calcium carbonate in a modified Merseburg process. The heat from the ammonium carbonate formation exothermicity increased the temperature in the gypsum conversion .
A schematic of the process is shown in Fig. 2 capture by liquid absorbents from a gas stream consists of an absorption tower (absorber or column) and a desorption tower (desorber, regenerator or stripper). For the ammoniabased CO 2 capture process, partly carbonated aqueous ammonia is used as the absorbing liquid. Pure aqueous ammonia cannot be used due to its extremely high ammonia ...
ammonium sulfate preparation is done in 23C o and the ratio of phosphogypsum to ammonium carbonate (400ml /192 gm phosphogypsum ) at reaction time( 4 ) hours The aim of this work focus on making a process flow diagram which is used in dealing with waste of phosphogypsum and production a useful product Keywords: ammonium sulfate; phosphogypsum ...
Ammonium carbonate is a salt with the chemical formula (NH 4) 2 CO it readily degrades to gaseous ammonia and carbon dioxide upon heating, it is used as a leavening agent and also as smelling is also known as baker''s ammonia and was a predecessor to the more modern leavening agents baking soda and baking is a component of what was formerly known as sal volatile .
The Merseburg method or the ammonocarbonation of gypsum (or anhydride) is a very old technology, developed for the first time by I. G. Farben before 1914. 13,14 Any type of gypsum, including phosphogypsum, can be reacted with ammonium carbonate to form ammonium sulfate and calcium carbonate through the Merseburg process.
The phosphogypsum was converted to saleable ammonium sulphate and precipitated calcium carbonate in a modified Merseburg process. The heat from the ammonium carbonate .
When ammonium carbonate is used instead of ammonia and carbon dioxide, it is necessary to be aware of its decomposition when the temperature is increased. As a result the temperature of the conversion reaction should ... why it is often called the Merseburg process. The economy of this process is crucial, and it is derived
Jul 09, 2012· Merseburg Process In light of all of the copper sulfate and sulfuric acid synthesis question threads, I was thinking that a discussion of a kitchenfriendly version of the Merseburg Process (or rather, the Ammonium CarbonateGypsum Process) would be in order.
Most simple ammonium salts are very soluble in water. One exception is ammonium hexachloroplatinate, the formation of which is used as a test for ammonium. The salts of ammonium nitrate and especially perchlorate are highly explosive, in these cases the ammonium is the reducing agent. In an unusual process, ammonium ions form an amalgam.

Properties of Ammonium Carbonate. Ammonium Carbonate decomposes at 58 °C. Therefore, this temperature is its melting point. Being a watersoluble compound, it is highly soluble in water; When we expose it to air, this salt converts into white porous lumps or powder of ammonium bicarbonate due to loss of ammonia and carbon dioxide and becomes ...
restricted use in building materials but a final decision for its use should be taken with the consideration of scenarios of use. The phosphogypsum was converted to ammonium sulphate and precipitated calcium carbonate in a Merseburg process that has been modified by omitting the CO 2 scrubbing towers. This modification reduced
MANUFACTURE OF AMMONIUM SULFATE FERTILIZER FROM FGD, commercially feasible The Merseburg Process for manufacturing ammonium sulfate from gypsum is based on the chemical reaction between gypsum and ammonium carbonate. Get Price Online Chat; Ammonium Sulfate As a Lawn Fertilizer Home Guides
6. Ammonium carbonate and ammonium bicarbonate can be used (9,10) as blowing agents in the production of various types of rubber. Gases can be released by heating or adding acid. Ammonium carbonate was one of the earliest blowing agents used with polymers. It was first used on rubber 19th century England (11). It is added to the rubber ...
Mar 23, 2016· We evaluated the chemical sequestration of carbon dioxide into the phosphogypsum from the Lowveld region of South Africa. The phosphogypsum was converted to saleable ammonium sulphate and precipitated calcium carbonate in a modified Merseburg process. The heat from the ammonium carbonate formation exothermicity increased the temperature in the gypsum conversion reactor .
The Merseburg Process for manufacturing ammonium sulfate from gypsum is based on the chemical reaction between gypsum and ammonium carbonate. Ammonium carbonate is formed by the reaction of ammonia and carbon dioxide in aqueous solution. The reaction produces insoluble calcium carbonate and an ammonium sulfate solution.
