The process design and economic evaluation of a conceptual 100,000 bbl/day synthoil plant charging 50,000 tons/day of western Kentucky coal and also producing 2130 tons/day of sulfur and 180 tons/day of ammonia was prepared, based on experimental data obtained on a 0.5 ton/day unit at the Pittsburgh Energy Research Center. The planned facility consisted of about 15 process units, including a 12,000 ton/day oxygen plant and an entrained-bed gasification plant. The reactor was designed to operate at an 810/sup 0/F inlet temperature, an 860/sup 0/F outlet temperature, at 4000 psig, and with a total hydrogen consumption of 556 million cu ft/day. Over-all plant thermal efficiency was estimated at 59.6%. The estimated over-all capital investment for the facility was, on a 1976 basis, $1900 million, of which $1670 million was depreciable; the cost of the coal mine was excluded. When the product oil cost was calculated and plotted as a function of the coal cost and the annual after-tax rate of return on equity for capital structures from 100% equity to 95% debt, with the assumptions of a 9% annual interest rate on debt and 5 yr of construction followed by 20 yr of operation. As an example, the product oil cost $22.60/bbl based on a debt-equity ratio of 70:30, a 12%/y after-tax rate of return on equity, and a $20/ton coal cost. Diagram, flowcharts, graphs and tables.
