Phase Equilibrium and Volumetric Properties of Coal-Derived Fluids. Quarterly Report, December 16, 1977--March 15, 1978

摘要

The thermodynamic properties of fluid mixtures are required for accurate design of equipment in which such fluids are stored, transported or separated. The basic goal of the present project is to obtain data for components and conditions where information is currently lacking. The mixtures studied will be chosen to approximate those which occur in the processing of coal-derived fluids. The research is divided into three major areas as follows: (1) design, construction and operation of a Burnett-type apparatus for measurement of volumetric properties (pressure-volume-temperature-composition relationship) of gases, and measurement of the properties of the pure substances and selected mixtures of H sub 2 , CO, CO sub 2 , CH sub 4 and H sub 2 O at conditions from ambient to 800 exp 0 F and 2,000 psia; (2) design, construction and operation of a variable-volume, windowed phase-equilibrium cell capable of operation to 800 exp 0 F and 2000 psia, and measurement of vapor-liquid equilibrium in mixtures composed of selected light hydrocarbons/heavy aromatic hydrocarbons/water; and (3) testing and/or devlopment of prediction methods for estimation of volumetric properties and phase equilibrium in mixtures of the type studied experimentally, and presentation of results in formats suitable for use in process design calculations.
