Precipitation of barium sulfate: Experimental investigation about …
2006年10月1日 · The precipitation of barium sulfate from aqueous solutions of barium chloride and sodium sulfate was investigated experimentally in a continuous Y-Mixer to avoid any mixing influence. Initial supersaturation and the initial ratio R = c B a free 2+ / c S O 4, free 2 − of the free lattice ions after complete educt mixing were varied over a ...
Barium sulfate - Wikipedia
Barium sulfate (or sulphate) is the inorganic compound with the chemical formula Ba SO 4. It is a white crystalline solid that is odorless and insoluble in water. It occurs in nature as the mineral barite, which is the main commercial source of barium and materials prepared from it.
16.3: Precipitation and the Solubility Product
2023年5月13日 · Barium sulfate is used in medical imaging of the gastrointestinal tract. Its solubility product is \(1.08 \times 10^{−10}\) at 25°C, so it is ideally suited for this purpose because of its low solubility when a “barium milkshake” is consumed by a patient.
Characteristic Reactions of Barium (Ba²⁺) - Chemistry LibreTexts
2023年8月29日 · Sulfate Ion Addition of a sulfate source, such as sulfuric acid produces a white, finely divided precipitate of barium sulfate: \[\ce{Ba^{2+}(aq) + HSO4^{-}(aq) <=> BaSO4(s) + H^{+}(aq)} \nonumber \]
Mixing, Reaction and Precipitation: The Barium Sulphate Precipitation ...
2015年6月23日 · This paper reviews critically the important studies that have been reported in the literature on the barium sulphate precipitation system with an emphasis on the influence of mixing on the reactive precipitation processes.
The precipitation in 0D is modeled as a time-dependent system where barium chloride and sulphuric acid are assumed perfectly mixed at initial concentrations of 500 and 330 mol/m3. The 3D barium sulfate precipitation takes place in a tubular T-mixer consisting of a 10 mm long mixing pipe with a diameter of 1 mm. Two oppositely placed
Barium sulfate precipitation in jet reactors: Large eddy …
2020年6月1日 · The course of barium sulfate precipitation was investigated experimentally and through simulations in several jet reactors of different size and geometry. Key focus of the work presented in this study was better description and understanding of the precipitation process carried out in jet reactors and the choice of the best available ...
It has been demonstrated that precipitation of BaSO4 is affected by several factors including solution supersaturation, ionic strength, and temperature. Precipitation inhibitors play an important role in many industrial processes necessitating scale prevention.
Modeling of Mixing-Precipitation Processes: Agglomeration
2019年12月9日 · Precipitation of barium sulfate was carried out by mixing aqueous solutions of barium chloride and sodium sulfate under stoichiometric conditions and at a constant temperature of 25 °C. First, stock solutions were prepared by dissolving the salts in deionized water.
Inhibition of Barium Sulfate Precipitation During Water Injection …
2022年11月28日 · Results of static and dynamic tests indicated that DPAAI had the best performance for inhibiting barium sulfate precipitation. Moreover, DPAAI could prevent the heterogeneous nucleation of barium sulfate and was effective in blocking the formation of barite and inhibiting crystal growth.
