Gas Treating Units are an integral part of gas processing plant's operation. An amine used as a solvent to absorb hydrogen sulfide (H2S) and carbon dioxide (CO2) from sour gas. More than two decades of our operational experience demonstrated that the metallurgy selected at the initial design performed satisfactorily under normal operating conditions. However, these units experienced accelerated corrosion with complex damage mechanisms to varying extent due to various factors.
The affected component can often become the source of major incident risk and therefore, timely integrity management is crucial to ensure Plant’s safety and reliability. While these corrosion concerns in new plants can be efficiently addressed by appropriate design and material selection, cost effective control of accelerated corrosion in existing plants remains a challenging task.
