A coal slurry pump development program for coal liquefaction was conducted by Rocketdyne Division, Rockwell International for the Department of Energy, Division of Fossil Fuel Processing. The program was initiated in October 1979 and consisted of fabrication and testing of a high-capacity, high-pressure, prototype, centrifugal slurry pump module that meets the following requiremennts for a coal/oil slurry with 50% concentration and 200 mesh coal: flowrate of 2500 gpm; operating pressure of 3000 psi; temperature of 550 F; pressure rise of 500 psi; a rotative speed of 3600 rpm; and a horsepower of 960. A two-stage, centrifugal slurry test pump was fabricated from steel castings and high wear-resistant materials for components exposed to slurry such as: cast white iron, titanium carbide, and tungsten carbide. A unique hydraulic design was utilized to reduce the severe wear on impeller and volute cutwater. The slurry pump incorporates a unique high-pressure, hydrostatic fluid seal capable of 3000 psi operating pressure. A slurry test facility for testing the centrifugal slurry pump was constructed at the Colorado School of Mines Research Institute (CSMRI), Golden, Colorado. The facility contains an 8-inch-diameter test loop, 1.7 million Btu/hr gas-fired oil heater, slurry head tank, boost pump, purge oil storage tank, high-pressure seal purge oil system, and a centrifuge/polishing filter system for recovering purge oil from the closed-loop coal slurry system. The prototype slurry pump successfully completed a three-phase hydraulic and wear test program in hot oil and hot coal/oil slurry, and achieved nearly continuous operation in slurry in excess of 242 hours with minimum wear. The feasibility of utilizing high-pressure centrifugal slurry pumps for coal liquefaction has been successfully demonstrated and further development is highly warranted. 73 figures, 19 tables.
