Assessment of Slurry Pump Technology for Direct Coal Liquefaction Demonstration and Pioneer Commercial Plants

摘要

This report examines the technical status of slurry pumps in coal liquefaction service. Three specific pump applications (1) coal slurry feed recirculation and pressure boosting, (2) high pressure coal slurry feedings, and (3) vacuum columns bottoms pumping are considered in this study. For each applications, pilot plant experience and specifications for demonstration and commercial plants are summarized. The uncertainties in the scale-up of these pumps to commercial sizes and the development and testing needs for eliminating these uncertainties are identified. 69 references, 7 figures, 13 tables.
