Evaluation of the Synthoil Process. Volume I. Process Design and Economic Evaluation of a 100,000-Barrel/Stream Day Facility.

摘要

A conceptual process design and a cost estimate for a 100,000-bbl/day Synthoil facility are presented. The design was based on experimental data obtained at Pittsburgh Energy Research Center and uses an operating pressure of 4000 psig in the reaction section. Total coal feed rate to the facility is 50,133 tons/day, based on a Western Kentucky coal with a moisure content of 9.2%. Capital investment was estimted to be $1897 million in first-quarter 1976 dollars, including $229 million working capital. The price of the fuel oil produced by the facility was calculated as a function of the debt-equity ratio, the annual earning rates on debt and equity, and the cost of coal. Using a debt-equity ratio of 70/30, an interest rate on debt of 9%, an after-tax earning rate on equity of 12%, and a coal feed cost of $20/ton, the price of the product oil was $22.60 per barrel. The calculated overall thermal efficiency of the facility was 59.6%. (ERA citation 02:055615)
