Testing of high temperature coal slurry pump packings
This report presents the results of a test program of packing designs and materials for high temperature coal slurry plunger pump services. The work was conducted to support the investigations and development of reliable and cost-effective reciprocating coal slurry pumps for future coal liquefaction process application. The short-term objectives were to screen, test and evaluate the state-of-the-art, commercially available packing designs and materials for the coal slurry feed pumps at the coal liquefaction pilot plants. Four major tasks were completed: failure analysis of slurry feed pumps packing components; selection of commercial packing designs and materials for testing; laboratory testing of high temperature coal slurry pump packings; and field testing of selected coalslurry pump packings. The results are presented. The primary root causes of the packing failures experienced at the pilot plants were identified as: insufficient packing lubrication, ineffective plunger flushing, unstable plunger alignment conditions of the pump, packing material incompatible to slurry and solvent, and undesirable packing installation, start-up, standby, and maintenance.
