producer was operating three 2-stage Ajax DPC-600 compressors. Suction pressure swings lead to the units
shutting down to prevent overloading, thus reducing each unit's run time and requiring personnel to travel out to
the remote units to restart them. The operator
therefore had been running the units conservatively
in order to accommodate the pressure swings
without shutting down, however that resulted in less
overall production.
An engineering study was commissioned to
evaluate the compressor configuration to identify the
best means for operating each unit via automatic
control and unloading to cover the entire operating
range. Goals were to keep the engines running
safely as field condition changed, and also to
increase capacity during normal operation to
minimize the number of units that had to be
operated at any time. Various alternatives were
evaluated including a single 685 in3 (11.2 L) fixed
volume pocket; parallel 192 and 383 in3 (3.1 and 6.3
L) fixed volume pockets; parallel 114, 228, and 342

in3 (1.9, 3.7 and 5.6 L) fixed volume pockets, and an automatic variable volume pocket. In order to evaluate the
alternative solutions, performance was compared at more than 1000 operating points within the operating range
noted in Figure 37. The highest flow possible at each point was plotted for each case at each condition and the
curves were overlayed for comparison. Over the range of 160 to 240 psig (11.0 to 15.5 bar) suction and 900 to
1000 psig (62.1 to 69.0 bar) discharge, the highest average flow was possible with the automatic variable volume
pocket, however, the 3-volume pocket (the 2nd from the top surface in Figure 37) provided average flow that was
