Barium sulfate - Wikipedia
Almost all of the barium consumed commercially is obtained from barite, which is often highly impure. Barite is processed by carbothermal reduction (heating with coke) to give barium sulfide: BaSO4 + 4 C → BaS + 4 COIn contrast to barium sulfate, barium sulfide is soluble in water and readily converted to the oxide, carbonate, and halides. To produce highly pure barium sulfate, the sulfide or chloride is treated with sulf…

Barium Sulfate Scale - stone Contaminant …
Why is Barium Sulfate Scale a problem? Although not as common as calcium carbonate and calcium sulfate scales, barium sulfate deposits have long plagued oil field and gas production operations. These scales interfere with fluid flow, enhance corrosion, causes production losses, result in equipment replacement, damage equipment and may host ...
Barium Sulphate & Barium Sulphate …
Barium sulfate is practically insoluble in water, acids (an exception being hot concentrated sulfuric acid), and bases. Due to its extremely low water solubility, barium sulfate, as compared to other barium compounds, is non-toxic. Today, barite (heavy spar) is the only technically used base material for all barium compounds and for barium ...

Common Uses of Barium | Owlcation
04.03.2012 · Barium Sulfate in Oil Production: Barium Sulfate is primarily used when drilling for new oil wells, which is by far the most common use for barium. It is combined with water and some other minerals to create drilling mud. This "mud" gets pumped into the drilling holes, and because of its weight, it helps to prevent the oil from exploding out into the environment; a method BP is apparently ...
Barium Sulfate - an overview | ScienceDirect Topics
Barium sulfate is one of the most difficult types of scale to inhibit in oil- and gas-production systems because of its physical hardness and its stone and thermal stability [74]. Barium sulfate is most commonly inhibited with either phosphonate or polymeric scale inhibitors deployed at substoichiometric concentrations. The effect resulting from the use of combinations of two or more scale ...
Physical Properties of Barium Sulfate | Sciencing
Barium is a soft, reactive, silvery-white, alkaline earth metal, somewhat resembling metallic calcium. Sir Humphry Davy first isolated it in 1808. The periodic table lists the alkaline earth metals from lightest to heaviest as beryllium, magnesium, calcium, strontium and barium. Barium sulfate, BaSO₄, is one of ...
