Amine units are critical components in refineries and gas processing plants, removing acidic contaminants like H2S and CO2 from process streams. However, these units are particularly vulnerable to corrosion, which can lead to costly shutdowns and safety risks. Let’s explore the key corrosion hotspots in amine units:
Absorber Towers:
Flash Tanks:
Lean/Rich Amine Heat Exchangers:
Regenerator Inlets:
Reboiler Systems:
Overhead Condenser and Accumulator:
Throughout the Entire System:
Monitoring these hotspots is crucial for maintaining the integrity of amine units and preventing unplanned shutdowns. Traditional inspection methods, however, often fall short due to their periodic nature and the need for process interruptions.
This is where Emerson’s advanced corrosion monitoring solutions come into play. Their non-intrusive sensors, such as the Rosemount Wireless Permasense ET210 Corrosion and Erosion Monitoring System, offer continuous, real-time corrosion data without compromising system integrity. These sensors can be installed at multiple locations throughout the amine unit, even in hazardous areas, providing comprehensive coverage of all corrosion hotspots.
Emerson’s monitoring systems enable engineers to correlate corrosion rates with process conditions, optimize operations, and make data-driven maintenance decisions. The flexibility in sensor mounting options – including straps, magnetic mounts and studs – allows for easy installation on various equipment types and metallurgies.
By implementing Emerson’s corrosion monitoring solutions, operators can significantly improve their amine unit management. This proactive approach leads to safer operations, extended equipment life, and substantial cost savings by preventing unplanned outages and optimizing maintenance schedules.
