Barium sulfate (BaSO 4), often just called barium in radiology parlance, is a salt of barium (Ba), a metallic chemical element with atomic number 56.Barium is considered one of the heavy metals. Unlike barium and many of its other salts, barium sulfate is insoluble in water and therefore very little of the toxic barium metal is absorbed into the body.
Barium Sulfate deposits have long plagued oil field and gas production operations. The deposition of barium sulfate scale on tubes and vessels can result in plant shutdown, production losses, equipment replacement, and cleaning costs. Barium sulfate scales once formed on the equipment surfaces are extremely difficult to remove.
The levels of soluble barium in the treated water from processes using barium sulfate or barium-sulfate-impregnated media are not a concern in the water supply. The barium MCL is 2 mg/L whereas about 0.2 mg/L barium was observed in process effluent where barium sulfate impregnated alumina was used to remove radium (Garg and Clifford, 1992) 6.
Mar 10, 2009· EP-B 0 445 785 describes a process for producing barium sulfate having a lamellar crystal morphology, in which the diameter-height ratio is 5 to 100 μm and the ratio of the square of the circumference of the lamella to the surface area of the orthogonal production plane is 20:1 to 150:1.
In this work, the use of a spinning disk reactor as a unit for a reaction−precipitation process is investigated. An experimental study is reported concerning the precipitation of barium sulfate from aqueous solutions at 25 °C on a spinning disk of 0.5 m in diameter. At a rotational speed higher than 900 rpm, spontaneous precipitation took place and crystals ∼0.7 μm in size were produced.
Why Barium Sulfate can Replace Titanium Dioxide / Superfine Barium Sulfate Process Technology. Barium sulfate can be pulverized to 1-8μm particle size without scarifying the whiteness and hiding power. Hence, it is applied to latex paint to replace part of titanium dioxide.
Scale-inhibitor squeeze treatments can sometimes bring undesirable side effects. These side effects include: process upsets, poor process and discharged water quality on initial flowback, extended cleanup period, deferred oil, and the potential for a permanent decrease in oil production combined with an increase in water production.
Barium sulfate was first applied as a radiocontrast agent in X-ray imaging of the digestive system in 1908. Occurrence and production. The abundance of barium is 0.0425% in the Earth's crust and 13 µg/L in sea water. The primary commercial source of barium is baryte (also called barytes or heavy spar), a barium sulfate mineral.
Jan 21, 2014· Shanghai Chang Lei specializes in the production of large mining crushing equipment, and provides major brands crusher parts, featured by precision machining, expertise, quality service and strict ...
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 bacteria.
barium sulfate manufacturing process. Barium sulfate - Brief Profile - ECHA - Europa. It may, for example, originate from the starting materials or be the result of secondary or incomplete reactions during the production process.
Barium sulfate is an inorganic salt that is mainly used in the production of concrete and as X-ray contrast medium. Occurrence: Barium sulfate can be found in some minerals; particularly the mineral barite is a large source of barium sulfate. The purification and extraction of barium sulfate from ...
Production and Properties of Barium Sulfate. Mirabilite-black ash: mix the raw material of barium sulfide (refer to preparation of barium sulfide) with mirabilite which has calcium, magnesium being removed and carry out the reaction at 90 °C to generate the barium sulfate precipitate.
Barium carbonate standard powder is used in the production of special glass, glazes, brick and tile industry, ceramic and ferrite industry. Barium carbonate standard powder is also used for removing of sulfates in phosphoric acid production and chlorine alkali electrolysis.

BARIUM AND BARIUM COMPOUNDS 97 5. PRODUCTION, IMPORT/EXPORT, USE, AND DISPOSAL 5.1 PRODUCTION Barium is a dense alkaline earth metal that occurs naturally in ore deposits and makes up 0.05% of the Earth's crust (Genter 2001). Barium and its compounds may be found in nature or produced industrially for various uses.
10.1 Precipitation of Barium Sulfate – Pre-Lab Questions ... In this experiment, the mixture of two solutions, sodium sulfate ( Na2SO4) and barium chloride (BaCl2), forms a precipitate. A precipitate is a solid formed during a reaction between two ... The final step in the process is to evaluate the overall efficiency of the reaction by ...
The barium sulfate sold by Solvay Fluorides, LLC is used in industrial applications and processes. Barium sulfate is used primarily as a whitening agent or as a support for other chemicals in industrial applications. Barium sulfate is sold as an odorless white solid. Barium sulfate is a relatively non-hazardous chemical.
barium-carbonate) Process is a most cost-effective process as the sludge produced is processed back to the process raw materials ... production of elemental sulfur. The solution pH, conductivity and ferrous iron concentration were monitored as the reaction proceeded.
Innovative Precipitated barium sulfate production technology: low cost and safety. The new production method of precipitated barium sulfate, is by salt melting process. It is a new technology, both safe and simple and applicable. In order to simplify the precipitation process of barium sulphate production, this invention can be mixed with ...
Barium sulfate Chemical Properties,Uses,Production Chemical Properties Barium sulfate has its chemical formula BaSO4. It is colorless or white orthorhombic crystals with relative molecular mass of 233.4, the relative density of 4.5 (15 ℃), the melting point of 1580 ℃, and the Refractive index of 1.637.
Its low specific surface area and diameter of Division and fast-flowing nature makes barium sulfate in polishing processes with low wear. Barium sulfate supports for automatic primer surface layer.
