United States
Department of Energy
Oil Shale Processing
Engineering Study
Roberts & Schaefer Company was awarded an engineering study
under a subcontract agreement between the University of Alabama
and the U.S. Department of Energy. This engineering study provided
the preliminary design of a commercial processing facility to
beneficiate 39,956 tons per day of run-of-mine eastern oil shale
to produce 4.38 million tons per year of concentrate. The process
plants design recovery of kerogen was 92%, which with hydroretorting
would produce approximately 20,000 barrels of oil per day.
Engineering design drawings provided in the study, included Process
Flow sheets, Piping and Instrumentation Diagrams, Electrical One-line
Drawings, and the Facility General Arrangement drawings. The engineering
design drawings were the basis for preparing the economic evaluation
of the facility. In preparing the capital and operating costs,
quotations were solicited for the major components of equipment
and materials. Estimating guidelines were applied to labor and
construction costs components, and historical data was used from
Roberts & Schaefer Company engineering and construction cost
database.
