OSTI ID:6438761
Prior to 1978, the Wilsonville Advanced Coal Liquefaction facility material balance surrounded only the thermal liquefaction unit and involved analyses of only the slurry stream and individual gas streams. The distillate solvent yield was determined by difference. Subsequently, several modifications and additional process units were introduced to this single unit system. With the inclusion of the deashing unit in 1978 and the catalytic hydrogenation unit in 1981, the process has evolved into a sophisticated two-stage coal liquefaction process and has the potential for various modes of integration. This report presents an elemental balancing procedure and a simplified presentation format that is sufficiently flexible to meet current and future needs. The development of the elemental balancing technique and the relevant computer programs to handle the calculations have been addressed. This will be useful in modelling individual unit performance as well as determining the impact of each unit on the overall liquefaction system, provided the units are on a steady-state basis. Five different material balance envelopes are defined. Three of these envelopes pertain to the individual units (the thermal liquefaction or TL unit, the Critical Solvent Deashing or CSD unit and the H-Oil Ebullated Bed Hydrotreating or HTR unit). The fourth or single stage material balance envelope combines the TL and CSD units. The fifth envelope is the two-stage configuration combining all three units. 3 references.
