Hot-Recycled-Solid pilot plant 1991 status report
At Lawrence Livermore National Laboratory, we are studying above ground oil shale retorting and have developed the LLNL Hot-Recycled-Solid (HRS) process as a generic second-generation, rapid pyrolysis retorting system in which recycled shale is the solid heat carrier. In 1984--1987, we operated a 1 tonne-per-day HRS pilot plant to study retorting chemistry in an actual recirculation loop. In 1989 we upgraded our laboratory pilot plant to process 4 tonne-per-day of commercially sized shale, allowing us, for the first time, to study pyrolysis and combustion using the full particle size. With the new facility we are able to produce enough oil for detailed characterization studies, can evaluate environmental consequences, and begin answering the many bulk solid handling questions concerning scale-up of the HRS process. In this paper we report on operations of our laboratory (4TU) pilot plant and plans for a field test unit (FTU) at approximately 100 tonne-per-day scale to be sited in the western United States. 3 refs., 11 figs.
