A Study for Determination of Equilibrium Ratios of C7+ Fractions
Abstract/Contents
- Abstract
- The C7+ fraction of hydrocarbon analysis of some well stream mixtures has been selected for further study. Specific gravity and molecular weight of the C7+ fractions are calculation for each well stream, and a correlation between them is obtained. The mole percent of the cuts constituting the C7+ fractions are evaluated, and two expressions relating the mole percent of the cuts to their molecular weights are found by curve fitting techniques. One of the expressions is the function of specific gravity of C7+ and the other is the specific gravity independent. Each well stream mixture is then flashed at different pressures and temperatures to obtain the composition of equilibrium vapor and liquid phases. K values of the C7+ fractions at the flash pressure and temperature are computed by dividing the mole fraction of C7+ in the vapor phase by that in the liquid phase. The flash calculations are performed on both specific gravity dependent and specific gravity independent analysis. K values of the C7+ fractions obtained from these two analyses are curve fitted utilizing a multi-variable linear regression analysis. Two simple specific gravity dependent and specific gravity independent equations are found from the regression analyses, which give the K values of C7+ fractions at specified temperatures and pressures. An error analysis for the method developed in this study is given. Comparison of the Ks developed by this method with those of other methods is also provided.
