component, distillate products are predicted in the bottoms. This treatment of the resid fraction corresponds to that of McKeegan and Klunder [El, who also assigned a single normal boiling point to the nondistillate material in their simulation of the separator system in the SRC-I1 coal liquefaction process (although they used a much higher temperature). The plot in Figure 4 for P 0.94 psia, as well as for P = 6.0 psia, reflects the presence of heavy resid treated as the 10910F pseudocomponent. These plots are in line with the experimental obser- vation of the presence of significant amounts of liquid distillate product in the vacuum bottoms stream. All simulation results for the vacuum fractionator pre- sented in Tables 5-7 and Figures 3-6 have treated the -heavy resid as a 1091OF pseudocomponent. CONCLUSIONS The very preliminary results reported here indicate that the use of petroleum- liquids correlations may result in an improvement over coal-liquids correlations in the simulation of the coprocessing of Lloydminster with Illinois No. 6 coal. Agreement between simulation and experiment is improved by using a higher assumed pressure than the experimental pressure for the vacuum fractionator, by treating the presence of water as a free water phase, and by treating the heavy resid as 109l0F distillate rather than an inert solid material. It is necessary to obtain better definition of the separation equipment used and the operating conditions employed, and to acquire a larger data set in order to evaluate the present capability for simulating the separation steps in coprocessing.
