Ammonium sulfate | (NH4)2SO4 - PubChem

Ammonium sulfate, is an inorganic sulfate salt obtained by reaction of sulfuric acid with two equivalents of ammonia.A high-melting (decomposes above 280℃) white solid which is very soluble in water (70.6 g/100 g water at 0℃; 103.8 g/100 g water at 100℃), it is widely used as a fertilizer for alkaline soils. It has a role as a fertilizer.

Generation of Fluid. After the pumping for hydraulic fracturing but before the production of hydrocarbons, the pressure in the well is allowed to dissipate; fluid returns to the surface through the wellhead and is collected and stored. This initial fluid, which is produced to the surface for about 14 days before product recovery, is called flowback.
