Informative articles from the experts in catalytic emission control technology.
One of the tradeoffs for the higher efficiency of new advanced class gas turbines (namely the G-, H-, and J-class machines) is increased thermal NOx make, which is caused by higher firing temperatures in the gas turbine combustors. The result is GT exit NOx concentrationsRead More
Incorporating real world operating data analysis into your SCR management plan is a topic that is gaining some well-deserved traction within the power industry. Combined Cycle Journal posted an article on November 8th, 2017 highlighting Environex Senior Engineer AndrewRead More
Selective catalytic reduction is a catalytic reaction which uses ammonia to reduce oxides of nitrogen (NOx) into harmless nitrogen (N2) and water. Because of this function, the SCR catalyst is sometimes referred to as a NOx catalyst in the industry. It has been used in manyRead More
In the real operating environment of an SCR catalyst, exhaust gas temperatures, flows, and other factors vary across the catalyst cross-section. These differences cause non-uniform wear and tear on the catalyst. Uncontrolled thermal events and poisons entrained in theRead More
