- A scoping study was performed on two conceptual flash hydropyrolysis processes. The two processes selected were the Cities Service and the Schroeder-Spencer Chemical Company (SCC) processes because they represent two aspects of the flash hydropyrolysis technology. The Cities Service process was designed primarily to produce substitute natural gas from North Dakota lignite, while the Schroeder-SCC process was designed primarily to produce a crude aromatic distillate-type oil from Pittsburgh No. 8 bituminous coal. Preliminary mass and energy balances were developed for conceptual plants designed to produce 250 MMscfd of substitute natural gas by the Cities Service process and 50,000 bbl/day of distillate oil by the Schroeder-SCC process. Preliminary economic evaluations were also made on the two processes based on cost data reported by the two process developers. The usable fuel energy efficiency of the Cities Service process was calculated to be 62 percent, while that for the Schroeder-SCC process was calculated to be 76 percent. The preliminary evaluations indicate that a more detailed engineering evaluation of the flash hydropyolysis process is justified after a firm data base for the process is established.
