S&R named System Integrator for eRCM Express
eRCM Express
Real-Time Reciprocating Gas Compressor Modeling
S&R Controls LP is an approved ACI Services system integrator for the eRCM Express.
The eRCM Express™ is in an integrated, real-time, variable measurement, monitoring system for reciprocating compressor modeling (RCM) technology. Real-time live data is fed from the unit control panel PLC to the eRCM Express. The eRCM model returns real-time gas compressor performance and safety prediction outputs.
Advantages of the eRCM Express
- Allow reciprocating compressor to achieve full performance.
- Removes operation map constraints.
- Calculates full rod loads and pin reversals per throw.
- Predicts safe performance across unit’s full operation map.
- Optimizes capacity and reduces cost.
- Provides OEM approved compatible modeling.
- Helps prevent continued operations in high mechanical stress.
- Models single and multi-stage compressors.
- Regulate capacity according to nomination targets.
Features of the eRCM Express
- Industrial Computer running eRCM Modeling Software
- Rated for installation inside the compressor unit control panel in Class 1, Division 2 areas
- Modbus/TCP Ethernet communications integrated with the PLC
- Utilize single-stage and multi-stage compressor models interchangeability
The PLC sends the following real-time data to the eRCM Express:
- Suction Pressure
- Discharge Pressure
- Speed
- Suction Temperature (per stage)
- Current Load Step
The eRCM sends the following real-time results to the PLC:
- Load Step Errors (Safety limits exceeded, per load step)
- Predicted Load BHP (per load step)
- Predicted Compressor Flow (per load step)
- Performance data per stage
- Performance data, including Rod Loads, per throw
- Next recommended load step up
- Next recommended load step down
- Minimum safe speed at current load step and conditions
- Maximum safe speed at current load step and conditions
- Minimum safe suction pressure at current load step and conditions
- Maximum safe suction pressure at current load step and conditions
- Isentropic Efficiency at current operating point
