Uses and applications
What the substance is used for, by industry and function
Dehydrating agent, food preservative, road treatment, freezing mixtures, sizing compounds, wood preservative, fire retardant.
In photography for making dry plates and light-sensitive papers, manufacturing mineral waters, NH4Br, fire-extinguishing compositions.
The major use for calcium bromide is as a component of high-density clear drilling, completion, workover, and packing fluids to control wellbore pressures. ... Calcium bromide finds other applications in photography, in medicine, in sizing compounds, as a wood preservative, and in flame retardant blends. An important new use for calcium bromide is in the control of mercury emissions at power generation units and incinerators.
(1) Applications in oil and gas well completion, workover, and packer brines (52-54%), specific gravity >1.7, (2) water treatment, (3) gravity separation fluid, (5) electrical conductivity fluid, and (5) dense non-aqueous phase liquid remediation of contaminated soils.
Industrial uses: Density modifier, Processing aids, specific to petroleum production, Other.
Consumer uses: Other.
How it is made
Common manufacturing techniques include reaction of calcium hydroxide, oxide, or carbonate with bromine and formic acid, or with formaldehyde. Another method involves the reaction of hydrogen bromide with calcium hydroxide in the presence of water and carbonates. The reaction mixture is acidified to pH 1-3 in order to convert at least a portion of the carbonates to carbon dioxide. Vacuum concentration, filtration, and drying result in a crystalline calcium bromide product, whereas spray-drying produces a powder.
By the action of hydrobromic acid on calcium oxide, carbonate, or hydroxide and subsequent crystallization.
