The U.S. Department of Energy's Industrial Technologies Program makes it easier for end-users check on their plant's NOX emissions.

The government's free software, called NOX and Energy Assessment Tool (NxEAT), helps plants in the petroleum refining and chemical industries assess and analyze NOX emissions and application of energy-efficiency improvements.

Users can inventory emissions from equipment that generates NOX and compare how various technologies and efficiency measures affect their costs and NOX reduction. By performing “what-if” analyses, users can look at their emissions from equipment such as fired heaters, boilers, gas turbines and reciprocating engines.
