Optimizing Cost and Performance for NOx Reduction
Refineries, chemical plants and industrial facilities that use fossil fuel fired heat sources in their process must consider the creation and destruction of oxides of nitrogen (NOx). Facilities may drive decision making on many factors, but two of the key criteria would be cost and performance. The knowledgeable manager needs to factor in the operating cost in addition to capital cost for the expected performance to consistently meet the regulated limit.
NOx reduction is driven by regulations that vary by region. The limits set in your specific region can be achieved in most facilities by either of two methods. In this presentation, we will review operating factors that affect any given facility by comparing burner selection with or without flue gas recirculation and selective catalytic reduction methods. Specifically, natural gas fired boilers that create process steam. Other fossil fuels would need additional equipment and considerations that will be touched on but not a focus in comparing these two methods.
Throughout the presentation we will discuss the factors and the sensitivity of the variables that would drive a decision maker toward the best possible solution.
