SRC-II process
Extensive laboratory and pilot plant experimental work on the Solvent Refined Coal Process has led to the development of an improved version of the process known as SRC-II. This work has shown considerable promise and plans are being made to demonstrate the SRC-II process using commercial size equipment in a 6000 T/D plant to be located near Morgantown, West Virginia. On the basis of recent economic studies, the products (both liquid and gas) from a future large-scale commercial plant are expected to have an overall selling price of $4.00 to 5.00 per million Btu (first quarter 1980 basis). The major product of the primary process is distillate fuel oil of less than 0.3% sulfur for use largely as a non-polluting fuel for generating electrical power and steam, especially in the east where utilities and industry are presently using petroleum products. For the longer term, the major growth opportunity for SRC-II fuel oil in the generation of electric power will probably be through advanced combustion turbine units with heat recovery boilers (combined cycle units). The light liquid fractions (naphtha and middle distillate) produced by the SRC-II process can be upgraded to a high octane unleaded gasoline to supplement petroleum-derived supplies. Significant quantities of pipeline gas are also produced at a cost which should be competitive with SNG from direct coal gasification. Light hydrocarbons (ethane, propane) from the process may be effectively converted to ethylene in conventional cracking plants to offset ethylene demand from petroleum-derived naphtha and gas oil, both of which could otherwise be used for other refinery products. In addition, certain fraction of the fuel oil might also be used in medium speed diesel engines and automotive gas turbines.
