The Corrosion Fouling Cycle in Amine Systems

Recommendations to Reduce the Impact of the Mechanisms of Corrosion in Amine Systems

Corrosion is a costly prob­lem in the oil and gas production industry, with significant safety and exposure risk. It contin­ues to be an industry challenge due to its complexity and diffi­culty to fully resolve. Revenue loss from an amine plant shut­down due to corrosion can be signif­icant. 


In a refin­ery, inability of the acid gas removal unit (AGRU) to treat acidic refinery fuel gas (RFG) coming from unit operations may reduce the ability of the refinery to run at capacity, cut­ting back on refinery output of final products such as gaso­line and diesel. If a 100000 b/d refinery is forced to run 10% (10000 b/d) below capacity due to AGRU issues, and assuming refinery products are averaging a selling price of $2/gal, reve­nue loss is in the range of $840 000/day. 


To minimize amine unit cor­rosion, many factors need to be considered, from original design to operation, mainte­nance and troubleshooting. Effective corrosion manage­ment is an important aspect of amine system management. In this article, we will review a range of amine system corro­sion management issues and focus on the ability of effective solids management to reduce corrosion issues.
