The model is capable of predicting the initial water condensation point in the pipeline and the concentration of different substances in the aqueous mixture. Calculated pressures are within 2% of experimental values, while liquid holdup (approx 4%) is in agreement with the value predicted by Eaton's correlation ( Eaton et al. Model calculations predicted the observed flow pattern, pressure and liquid holdup profiles reported in the case study. The case study compares model calculations with an experimental data set obtained from Eaton et al. In this paper, model performance is illustrated using a case study.

The model was benchmarked using several published works, details of which can be found in the work of Zaghloul (2006). Compositional changes in the aqueous phase may create the conditions for forming hydrates or acids. (4.10) is obtained by means of the Gauss-Legendre quadrature, a tech.

This is important in the light of compositional dependence of hydrate or acid formation. 5.2 Thermodynamic methodologies for the calculation of the solubility of APIs. PCalc for your Mac A fully featured scientific calculator with support for hexadecimal, octal and binary calculations, as well as an RPN mode, parentheses, programmable functions, and an extensive set of unit conversions. Results show the model is capable of predicting the hydrodynamic behavior as well as the compositional profiles of gas and water flowing in a pipe. The model described herein focuses on gas transmission with low-liquid loading conditions (h l/ d < 0.3). The tool couples complex hydrodynamic and thermodynamic models to describe the behavior of fluids flowing in a pipe. The current work presents a fully compositional tool for modeling systems exhibiting two-phase (gas/water) flow.
