Liquid–Gas Phase Equilibria of Hydrocarbons in Water + n-Pentane and Water + n-Hexane Mixtures

The pVT -properties of water +  n -pentane and water +  n -hexane mixtures in temperature intervals from 305  to 542 K and pressures up to 15 MPa were measured in a constant-volume piezometer. The line of phase equilibrium hydrocarbon–vapor with water and their critical parameters were determined. C...

Description
Summary:The pVT -properties of water +  n -pentane and water +  n -hexane mixtures in temperature intervals from 305  to 542 K and pressures up to 15 MPa were measured in a constant-volume piezometer. The line of phase equilibrium hydrocarbon–vapor with water and their critical parameters were determined. Critical temperatures and pressures are constant and close to 0.9 mol fraction of water, remaining the same as for the upper critical end-point, while the densities increase. All critical parameters decrease above 0.93 mol fraction of water. The common three-phase lines for measured systems are presented.
