Title: AIG Tuning, Catalyst for Life Forecasting

Many gas-turbine “bubble” units installed between 2000 and 2004 are operating with their original charge of SCR catalyst. These units have outlived the original catalyst warranty (typically three years) and have benefitted from a combination of conservative design and good luck. However, as these systems reach the decade mark, the design margins have diminished because of gradual (and inevitable) deactivation of the catalyst with age. As the catalyst nears its end of life, ammonia slip begins to increase exponentially. There are practical steps operators can take to avoid this scenario.
