Lee, S R; Brackett, D; Baldwin, K L

The root causes of the packing failures experienced at the coal liquefaction pilot plants are presented by five major hypotheses: insufficient packing lubrication, ineffective plunger flushing, unstable plunger alignment conditions of the pump, packing material incompatible to slurry and/or solvent, and undesirable packing installation, start-up, standby, and maintenance practices. These hypotheses will be used to guide the definition of test objectives for the laboratory and field tests of this program. Specifically, the planned test program is discussed briefly.
