They are the former dip tank, seven underground storage tanks, the sulfuric acid spills/overfills, and a stained area. The former dip tank has no evidence of a spill or release during the October 2009 Resource Conservation and Recovery Act (RCRA) site visit or during a WVDEP or EPA file review.
Word Equation. Barium Chloride + Sulfuric Acid = Barium Sulfate + Hydrogen Chloride. BaCl2 + H2SO4 = BaSO4 + HCl is a Double Displacement (Metathesis) reaction where one mole of aqueous Barium Chloride [BaCl 2] and one mole of aqueous Sulfuric Acid [H 2 SO 4] react to form one mole of solid Barium Sulfate [BaSO 4] and two moles of aqueous Hydrogen Chloride [HCl]

Barium (Ba) is obtained chiefly from the mineral barite. Barium is a soft, silvery, reactive metal. Because barium is so dense it is commonly used in some alloys, for example in spark plugs and ball bearings.
tion and scanning electron microscopy. Glucose and xylose yields by wet disk milling, ball milling, and hot-compressed water treatment were 78.5% and 41.5%, 89.4% and 54.3%, and 70.3% and 88.6%, respec-tively. Wet disk milling and hot-compressed water treatment increased sugar yields without decreasing their crystallinity.

The key is to remove as much sulfate as possible while barium is still sequestered as barium carbonate. The first step is always to eliminate the use of spent acid for pH control because this adds four times the amount of sulfate anion to the D0 . stage as does sulfuric acid. The good news about barium scale is that once barium sulfate forms,

Sulfuric acid is the most widely used of the strong inorganic acids. Average exposures to sulfuric acid mists in pickling, electroplating and other acid treatment of metals are frequently above 0.5 mg/m 3, while lower levels are usually found in the manufacture of lead–acid batteries and in phosphate fertilizer production. Exposure to ...

sodium hydroxide use since this invariably needs to be neutralized somewhere else with sulfuric acid. Even with this issue - barium concentrations are typically 1/100 of the calcium concentration15,16 and it may benefit the mill to tolerate a barium scale problem to avoid oxalate scale which can build up at a significantly faster rate.
