This report presents the results of 73 tests on the vacuum flash system of Process Development Unit P-99 performed during processing of three different coals; the second batch, fourth shipment (low ash batch) of Powhatan No. 5 Mine (LR-27383), Powhatan No. 6 Mine (LR-27596) and Ireland Mine (LR-27987). The objective of this work was to obtain experimental data for use in confirming and improving the design of the vacuum distillation column for the 6000 ton/day SRC-II Demonstration Plant. The 900/sup 0/F distillate content of the bottoms and the percent of feed flashed overhead were correlated with flash zone operating conditions for each coal, and the observed differences in performance were attributed to differences in the feed compositions. Retrogressive reactions appeared to be occurring in the 900/sup 0/F+ pyridine soluble material leading to an increase in the quantity of pyridine insoluble organic matter. Stream physical properties determined include specific gravity, viscosity and melting point. Elemental, distillation and solvent analyses were used to calculate component material balances. The Technology and Materials Department has used these results in a separate study comparing experimental K-values and vapor/liquid split with CHAMP computer program design predictions.
