This interim report presents the results of laboratory testing of selected packing designs and materials for coal liquefaction slurry feed pumps. The work was conducted as Task 3 of a high temperature packing test program (DOE Contract DE-AC22-81PC40090). The objective of the task is to test and to evaluate the packing candidates identified in Task 2 of the subject test program. Two types of packing tests were conducted in the laboratory; namely, static solvent compatibility tests and dynamic wear tests. In the static compatibility tests, the packings were immersed in different coal-derived solvents at 300/sup 0/F for 96 hours. Changes in physical properties which included weight, dimension, deformation (under axial loading), and resiliency (after the removal of the axial loading) were measured and analyzed. Details on the test system design, procedures, and data analysis are presented. In the dynamic wear tests, the packings were tested in a modified commercial reciprocating plunger pump with different coal-derived solvents as working fluids. The modification permitted the packings to be tested in a commercial stuffing box design configuration at high fluid temperatures and constant fluid pressure. Performance of the packings in terms of installation requirement, adjustment, and fluid leakage were monitored and analyzed. Details of the test system design, test conditions, and data anlaysis are presented. The Department of Energy directed this test program with the objective of initiating engineering efforts to overcome the packing problems experienced at coal liquefaction pilot plants. The results and conclusions of this program are not endorsement of any commercial packing design and/or material. Instead, the output of the program is intended to promote better understanding and communication of the existing technical information for future technology development.
