Soda Ash

DISCRIPTION

Soda Ash is also named Sodium Carbonate, Na2CO3. Molecular weight is 106.

APPLICATION

Soda Ash is used to remove soluble calcium salts from make-up water and mud.

CaSO4 + Na2CO3 -> CaCO3 + Na2SO4

Soda Ash is not recommended for treatment of cement contamination due to increase of pH.

Ca(OH)2 + Na2CO3 -> CaCO3 + 2 NaOH

RECOMMENDED TREATMENT

Soda Ash should be added in 0.72 kg/m3 (0.25 ppm) increments until desired results are obtained. The exact amount of Soda Ash required must be determined from the amount of calcium present in the mud. Approximately 0.265 kg/m3 (0.093 lb/bbl) of Soda Ash is required to precipitate 100 mg/l of calcium ion.
