Weight of crystalline CaCl2 and CaBr2 salt addition to brine (two-salt systems)
Input(s)
\(C_{95}\) : Concentration of \(95 \% \mathrm{CaBr}_{2}\) in the Initial undiluted Brine \((\mathrm{lbm} / \mathrm{bbl})\)
\(m_{94}\): Mass of \(94 \% \mathrm{CaCl}_{2}\) needed to weight up diluents water ( \(\mathrm{lbm}\) )
\(C_{94}\) : Concentration of \(94 \% \mathrm{CaCl}_{2}\) in the Initial undiluted Brine \((\mathrm{lbm} / \mathrm{bbl})\)
\(W_{i}\) : Water Fraction in the initial undiluted Brine \((\mathrm{bbl} / \mathrm{bbl})\)
Output(s)
\(m_{95}\) : Mass of \(95 \% \mathrm{CaBr}_{2}\) needed to weight up diluents water (lbm)
Formula(s)
\[
\begin{aligned}
& m_{95}=\left(V_{8.33}\right) \frac{\left(C_{95}\right)}{\left(W_{i}\right)} \\
& m_{94}=\left(V_{8.33}\right) \frac{\left(C_{94}\right)}{\left(W_{i}\right)}
\end{aligned}
\]
