4.7.5 Large Reciprocating Primary and Booster Compressor System
Figure 4-26 shows a semi-trailer mounted primary compressor system unit with
an Ingersoll Rand Model HHE, three-stage, reciprocating piston compressor. The
compressor is operated at 1,000 rpm. At this speed the compressor has a volumetric
flow rate of 1,500 scfm and a maximum pressure capability of 310 psig (at API
Mechanical Equipment Standards standard conditions). The aftercooling and
innercooling subsystems are at the left end (hitch end) of the trailer in Figure 4-26.
The prime mover is in the middle of the trailer and the compressor is mounted at the
right end (or aft end) of the trailer. The prime mover is a Caterpillar Model 3508.
The prime mover is a diesel fueled, turbocharged Caterpillar Model 3508 with a V-8
cylinder configuration. This prime mover produces a peak of 644 horsepower at a
speed of 1,000 rpm (at API Mechanical Equipment Standards standard conditions).
