Abstract: Part I -Preliminary process analyses of three different technically feasible processing schemes proposed by SUN TECH, INC for converting 100,000 BPCD of. ra, Paraho shale oil into military turbine fuels was investigated. Each processlng scheme is based on very limited, but pertinent, data generated by SUN TECH plus literature sources. The base processing scheme consists of severe hydrotreatin followed by sulfuric acid extraction the two alternate cases utilize moderate hydrotreating plus extractton for nitrogen removal and hydrocracking. Screening-type process designs and costs estimates were prepared for each case using the economic basis specified. Results indicate that shale oil fuels refineries are more capital intensive than a comparable size petroleum refinery. No attempt was made at optimization. Summary: This report covers work perfonned by Sun Tech, Inc. in Phase I of a contract with the United States Air Force. The Phase I objectives were to define and evaluate on paper the technology and potential economics (without the benefit of adequate laboratory and pilot plant data) for three different processing schemes for converting 100.000 barrels per calendar day of raw Paraho shale oil into aviation turbine fuels. Each processing scheme was developed using limited data generated by Sun Tech plus literature sources. Screening-type process design bases and cost estimates were prepared to compare various costs for maximum yields of JP-4 versus JP-8 jet fuel and to compare maximum yields of selected jet fuels versus a full slate of military fuels. Basic assumptions and conditions for developing Phase I economics were specified by the U. S. Air Force. No attempt was made in Phase I to optimize the processing configuration or product slate for maximum efficiency or minimum costs. The Base Case consists of hydrotreating the whole crude shale oil, washing with 80% sulfuric acid to remove the basic nitrogen compounds, followed by conventional fractionation to prepare either JP-4 jet fuel or JP-8 jet fuel. Alternate Case IA-l, JP-4 preparation and alternate Case A-2, JP-8 preparation processing schemes consist of hydrotreating the whole crude shale oil, Hel treating the hydrotreated product to extract the basic nitrogen compounds, followed by conventional fractionation, hydrocracking and distillation. Alternate Case IIA-l, JP-4 preparation and Alternate Case IIA-2, JP-8 preparation processing schemes consist of hydrotreating the whole crude shale oil, n,n-dimethylformamide (DMF) extraction of the heavy distillate fraction from the hydrotreated product to remove nitrogen and aromatic compounds, followed by conventional fractionation, hydrocracking and distillation. Overall thermal efficiencies vary from 82% in the Base Case to 74-76% in the alternate cases. Yields of JP-4 and JP-8 in the Base Case are about 29 and 36 volume percent of the crude, respectively. In alternate Cases IA-l and IIA-l, J P-4 is produced in yields of about 111 and 101 volume percent, respectively. In alternate Cases IA-2 and IIA-2, JP-8 is produced in yields of about 69 and 64 volume percent, respectively.
