With a large projected increase in U.S. use of coal under the National Energy Plan, improved sulfur dioxide controls are quickly needed. Physical coal cleaning may prove to be the most cost-effective method for reducing sulfur dioxide emissions from small boilers, since many small industrial users will find flue gas desulfurization too costly. The report gives results to date of a continuing assessment of coal cleaning technology. It discusses: (1) washability characteristics of coal, with emphasis on the correlations of various washability parameters; (2) current technology on coal comminution and gravity separation processes; (3) eleven major chemical coal cleaning processes, including evaluations and comparisons; (4) current technology on mechanical and thermal drying and oil agglomeration; (5) slurry sampling techniques, including a summary of a Bias Test Plan for two slurry samplers; and (6) coal preparation requirements for synthetic fuel conversion processes, in terms of particle size, moisture, ash, sulfur, and heating value. In addition, coal preparation requirements for 6 high-Btu gasification processes, 13 low-Btu gasification processes, and 5 liquefaction processes are summarized.
