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 chemical and thermal stability [74 ]. Barium sulfate is most commonly inhibited with either phosphonate or polymeric scale inhibitors deployed at …
Jan 01, 2009· At a concentration of 80 g L −1, barium precipitation achieved a sulfate removal up to 61.4% while calcium precipitation provided over 99% sulfate removal in raw and oxidized wastewaters and for both samples. Calcium precipitation was chosen to be performed after Fenton's oxidation; hence this process configuration favors the production of ...

Barium is a naturally occurring element found in the earth's crust (1) that enters the environment through the weathering of rocks and minerals (SRC). The principal barium minerals are barite ( barium sulfate) and witherite (barium carbonate) (1). (1) Boffito C; Kirk-Othmer Encyclopedia of …
The invention relates to a cyclic process for producing barium sulfate and lithium iron phosphate. In said cyclic process, (i) an aqueous solution containing lithium ions and sulfate ions is provided, and (ii) solid barium hydroxide is added at a temperature exceeding 50 DEG C, (iii) the barium hydroxide being added for a period of less than 15 minutes.
The sample containing sulfate is then reacted with an alcohol solution of barium chloride and methylthymol blue (MTB) at a pH of 2.5-3.0 to form barium sulfate. The combined solution is raised to a pH of 12.5-13.0 so that excess barium reacts with MTB. The uncomplexed MTB color is gray; if it is all chelated with barium, the color is blue.

Sodium sulfate ( Na2SO4) is the sodium salt of sulfuric acid. Anhydrous sulfate is a white crystalline solid also known as the mineral thenardite, while the decahydrate Na 2 SO 4 .10H 2 O has been known as Glauber's salt or mirabilis. Na 2 SO 4 .7H 2 O is transformed to mirabilite when it is cooled.

Jan 06, 2015· If sulfate must be further reduced ("polished"), an add-on process such as barium, CESR, or SAVMIN is recommended. As a polishing step for sulfate removal, barium salts can be added to precipitate barium sulfate, which has a very low solubility in water, with the final sulfate concentration limited only by the amount of barium added and ...
Mar 11, 2005· This invention relates to a process for the continuous production of barium sulfate consisting of microcrystalline particles produced by precipitation, wherein a barium salt solution and a sulfate solution are simultaneously and continuously brought together in equimolar quantities at a temperature of 30 to 90° C., with constant stirring, the precipitating suspension is withdrawn …
The present invention relates to a process for the production of barium sulfate and lithium metal phosphates. Both barium and lithium metal phosphates have a great industrial importance: Barium sulfate is used in particular for the manufacture of photographic papers, paints and plastics as well as in medical diagnosis and medical …
Jan 15, 2018· Seawater has a high-sulfate content; formation waters often have high-barium contents. Mixing these waters results in barite deposition. If this mixing/precipitation occurs within the reservoir far removed from a vertical wellbore, there will generally be little impact on the production of hydrocarbons.
Barium is a chemical element with the symbol Ba and atomic number 56. It is the fifth element in group 2 and is a soft, silvery alkaline earth metal.Because of its high chemical reactivity, barium is never found in nature as a free element.. The most common minerals of barium are baryte (barium sulfate, BaSO 4) and witherite (barium carbonate, BaCO 3), both insoluble in water.

Dec 05, 2019· When these processes are ineffective, production operators are often forced to shut down production, move in workover rigs, to pull damaged tubing out of the well, and replace the tubing. Nevertheless, barium sulfate is extremely resistance to both chemical and mechanical removal.
of carbonate and sulfate minerals. One of these sulfate minerals is barite (barium sulfate), which is known to readily incorporate radium (Ra) in its structure. Many studies of radioactive scale from oil-field equipment have documented that barite is the primary host of oil-field NORM and that the
Oct 01, 2006· It is suggested that the specific adsorption of barium and sulfate ions on barium sulfate is involved in the growth and nucleation mechanism. Judat and Kind [8] studied the particle formation process of barium sulfate under stochiometric conditions and at different supersaturations in a fast mixing device, to avoid any mixing influence.
