An existing vapor recovery compressor in a remote location would periodically shut down, causing a tank to over-pressure and vent hydrocarbon gases to the atmosphere.
Operators would then be dispatched to correct the problem, but they needed to drive 40 miles to get to the compressor station.
Solutions
A backup compressor was installed (by others).
Installed a PLC to automate both the primary and backup compressors with lead/lag control based on operator-defined setpoints.
Installed a SCADA system to collect critical compressor data from a remote location to the operator control room so operators could monitor compressor status and schedule maintenance before breakdowns occurred.
Provided detailed electrical drawings including:
PLC drawings
Conduit Layout drawings
Motor control drawings
Results
More productive employees.
More reliable equipment.
Able to achieve environmental compliance.
