| Abstract |
This paper describes a prototype program modelling the state-space of the two-component system over a wide range of temperatures and pressures [ 0 T 1075 0 p 1600 bars abs Using experimental data from a number of sources, a description is given of the surfaces which divide the three-dimensional T-p-X state-space into its eight regions, each corresponding to one of the various possible equilibrium regimes of fluid-solid states. Approximate correlations, which are based on the primary variables temperature T, pressure p and the mass fraction of chloride X in the solution, and which delineate these regional boundaries, are given here; the correlations are being implemented in a subroutine suitable for use within a numerical reservoir simulator. |
