Pipeline gas from coal-hydrogenation (IGT hydrogasification process). Project 9000 monthly status report, April 1--April 30, 1977
Test 60 in the HYGAS pilot plant was conducted and 186 hours of self-sustained operation were achieved. The pretreater operation was satisfactory at an average temperature of 775/sup 0/F. Slurry feed to the reactor was terminated when we were unable to fix a leak in a Grayloc flange on the reactor steam-spent char carrier line. The test was interrupted twice, once when solids flow out of the second-stage gasifier stopped and once when mechanical problems occurred in several pumps. The reactor was in excellent condition after the run. Preliminary results for several, short, steady-state periods, selected for analysis, are presented. The light-oil recovery unit operated satisfactorily. The liquid-phase methanation unit was operated for 2 hours until a process upset caused flooding in the quench system. This, in turn, caused a carry-over of diglycolamine solution into the liquid-phase methanation unit, reducing the activity of the catalyst by two-thirds. The spent catalyst has been replaced.
