Gas Turbine Operation Improvement with Multi-Function Catalyst
There have been recent catalyst technology advancements where NOx, CO and VOC emissions can be reduced with a single layer of catalyst. Not only has this allowed for plants to meet more aggressive emissions requirements in the same footprint, but it has also provided more options for addressing emissions induced plant operational limitations.
With US power generation capacity shifting towards renewables, the typical operation of gas turbines has also shifted. Previously base-loaded or peaking plants are being asked to operate on a Duck Curve, providing makeup capacity in the mornings and afternoons when solar generation is weak. The result is frequent shutdowns, steep ramp rates and long periods of operation at minimum load; all of which may have not been considered when designing the plant emissions equipment with respect to the site’s permit.
Multi-Pollutant Catalyst has been designed to eliminate emissions limited start-up and shutdowns; as well as reduce plant minimum load where emissions have previously been a factor. CORMETECH will present actual field data from before / after installations and explore case studies where Multi-Pollutant Catalyst has provided unique solutions for unique plant issues.
