Carbon Dioxide (CO2)

Typical Applications:

• Akalinity adjustment in water and waste water treatment
• Various industrial, food and beverage applications

Special Considerations:

• Proper personal protective equipment, eye wash stations, and a safe chemical metering system should be used.

Metcon Product Recommendation
For safe, reliable, and accurate handling and metering of the chemical, Metcon recommends a complete, packaged pressure gas feed system. 

1. Storage & Handling

• To monitor inventory, electronic scales for cylinders are the preferred options.

2. Chemical Metering

• A factory engineered, assembled and tested gas metering system is provided with a two stage regulator, local terminal box, mass flow controller, local flow indicator, isolation valves and bypass arrangement.
• Systems are designed to meet plant requirements for redundancy.
• The manufacturer should provide all of the appurtenances required for safe and accurate metering (back pressure / pressure relief valves). All materials are compatible for ammonia.

3. Controls & Instrumentation 

• The carbon dioxide gas system has a local termination box that can remotely increase or decrease the metering rate based on plant requirements. The mass flow controller can also provide feedback to the plant PLC, indicating flow rate.
• For akalinity adjustment applications, Metcon can supply pH analyzers and controllers
• Metcon can also provide real time monitoring, process controllers for automatic addition rate adjustments, and a videographic recorder for traceability and data recording.
