Summary
This report compares the results of simulated material balances produced by using selected available thermophysical property correlations and the ASPEN (Advanced System for Process ENgineering) simulator with pilot plant data. In order to conduct such a study, a preprocessing program, COALIQ, was developed at the Oak Ridge National Laboratory. This program produces an ASPEN input file given the characterization data for the coal liquid and selected thermophysical property correlations. Essentially three sets of thermophysical property correlations have been examined. The first set of correlations is based on petroleum liquids and was developed by Cavett; the last two sets developed by Starling and Wilson, respectively, are primarily based on data bases of pure compounds representing coal liquids. The results of the comparison between data and simulations show that under moderate pressures and temperatures reasonable K-values are obtained for systems containing hydrogen, methane, and coal liquid; however, near critical conditions, the overall deviations are more pronounced. Variations caused by the use of different thermophysical property correlations were not large. However, such deviations indicate that better methods are needed to simulate water-hydrocarbon mixtures with ASPEN than those which were used. Also, equations of state which behave robustly near the critical region should be included. Finally, a preliminary section on transport properties has been included, along with a review of some transport properties that appear in the literature. Recommendations for future work on transport property correlations have been made. 45 references.
