Sodium Bromide
Sodium Bromide brine is used as a completion and workover fluid either by itself or with sodium chloride, potassium chloride or bromide, or with zinc bromide. Its main advantage is in formations containing carbonate and/or sulfate ions which give rise to precipitation in the presence of other multivalent completion...
1. General Description
Molecular formula: NaBr
Molecular weight: 102.89
CAS No.: 7647-15-6
EC No.: 231-599-9
2. Applications:
Sodium Bromide brine is used as a completion and workover fluid either by itself or with sodium chloride, potassium chloride or bromide, or with zinc bromide. Its main advantage is in formations containing carbonate and/or sulfate ions which give rise to precipitation in the presence of other multivalent completion or workover fluids. Depending on the fluid composition and the required crystallization temperature, solutions of up to 12.3 ppg (1.47 gr/ml) NaBr/NaCl or 19.2 ppg (2.3 gr/ml) NaBr/ZnBr2 can be prepared.. It can also be used to oxidize the mercury present in the coal or industrial waste water, thereby enhancing the overall removal of mercury in downstream pollution
