The expanded use of domestic coal supplies as a substitute for imported petroleum will require significant expansion and modernization of the coal preparation industry. The Oak Ridge National Laboratory has assembled a multidisciplined team to study the needs of this industry and to undertake a development program with the goal of improving the efficiency and practice of coal beneficiation. Automated on-line analytical instruments are key elements in accomplishing this goal. On-line ash monitors are commercially available and have been successfully used in coal preparation plants worldwide. On-line sulfur meters, based upon prompt neutron activation analysis, have been developed. These systems can be modified to determine ash and calorific value. A moisture monitor, based upon microwave attenuation can be added to the sulfur meter. Nuclear density gauges are the only on-line process control instruments used in coal preparation plants. Worldwide development activities related to on-line analytical instruments are summarized, and development needs for product quality and process control instruments are discussed. 9 figures.
