Gas hydrate dissociation pressure
Input(s)
\(\gamma_{h}\): Specific Gravity of Hydrate-forming Components (dimensionless)
\(F_{m}\): Molar Ratio between the Non-hydrate-forming and Hydrate-forming Components (dimensionless)
\(\mathrm{T}\): Temperature \(\left({ }^{\circ} \mathrm{R}\right)\)
Output(s)
\(\mathrm{p}_{\mathrm{h}}\): Disassociation Pressure \((\mathrm{psi})\)
Formula(s)
\[
\begin{aligned}
\mathrm{p}_{\mathrm{h}}= & 0.1450377 * \exp \left\{\left[\frac{2.50744 * 10^{-3}}{\left(\gamma_{\mathrm{h}}+0.46852\right)^{3}}+F_{m} *\left(1.214644 * 10^{-2}\right)+\left(-4.676111 * 10^{-4}\right) * \mathrm{~F}_{\mathrm{m}}^{2}+0.0720122\right]\right. \\
& \left.* \mathrm{~T}+\frac{3.6625 * 10^{-4}}{\left(\gamma_{h}+(-0.485054)\right)^{3}}+\mathrm{F}_{\mathrm{m}} *(-5.44376)+F_{m}{ }^{2} *\left(3.89 * 10^{-3}\right)+(-29.9351)\right\}
\end{aligned}
