Rincon Amine Plant


  • Corrosion problems at an Amine Plant eventually caused a Contactor (at about 1000 psi) to break free from its foundation and crash into a compressor building, narrowly missing several gas compressors. This caused gas production to drop until a replacement plant could be constructed.


  • Installed new PLC to control the new Amine Plant.
  • Installed new HMI to interface with the Amine Plant PLC. Integrated this HMI with the existing plant-wide HMI, adding a new interface, new screens, and a streamlined network architecture.
  • Upgraded the existing SCADA system with new computers, network switches and protocols, and PLC communication cards.
  • Modified PLC and HMI programming to allow safety devices to be placed in bypass (with an administrator password) to allow for monthly testing without shutting down the plant.
  • Installed real-time corrosion monitoring system.
  • Provided detailed electrical drawings including:
    • PLC drawings
    • Conduit Layout drawings
    • Interconnection drawings
    • Motor control drawings
    • Networking drawing


  • Increased product quality.
  • More productive employees.
  • More reliable equipment.
  • Able to achieve environmental and safety compliance.
