Phase Behavior of Coal Fluids: Data for Correlation Development. Report for the Period May 1, 1986-July 31, 1986

摘要

The effective design and operation of processes for conversion of coal to fluid fuels require accurate knowledge of the phase behavior of the fluid mixtures encountered in the conversion processes. Multiple phases are present in essentially all stages of feed preparation, conversion reactions and product separation; thus, knowledge of the behavior of these multiple phases is important in each step. The overall objective of the author's work is to develop accurate predictive methods for representation of vapor-liquid equilibria in systems encountered in coal-conversion processes. During the present report period, simple representations were developed for the solubilities of CO sub 2 and ethane in heavy n-paraffin solvents. These complement the more complex representations developed previously by Gasem and Robinson for the CO sub 2 + n-paraffin systems. The simplified representations express the interaction parameter C/sub ij/ (or k/sub ij/) in the Soave-Redlich-Kwong equation of state as a function of the carbon number of the solvent. 10 refs., 8 figs., 1 tab.
