Morton Gas Plant

Problems

• New production was causing sales gas quality to decrease because of higher CO2 content.

Solutions

• A new Amine Plant was constructed (by others) to strip the CO2 out of the sales gas stream.
• Installed a PLC to control the new Amine Plant.
• Installed a new HMI to allow the operators to interact with the PLC and control process conditions.
• Installed new SCADA system to allow operators to remotely access the local PLC / HMI and respond to alarm conditions without having to drive to the plant.
• Added a phone dialer to the SCADA system to alert operators to any alarms or abnormal process conditions.
• Provided detailed electrical drawings including:
  • PLC drawings

Results

• Increased product quality.
• More productive employees.
