In an interview with Editor Linda Becker, Matthew Konkle with Dürr Megtec explains the types of technologies used for emissions control in the process industries and offers advice for proactive and reactive maintenance of these systems.

  • As you note in the lead off of your article, industrial processes produce NOX as a byproduct of processing and combustion. Exhaust-gas and air-pollution-control technologies are used to prevent the formation of NOX and other hazardous air pollutants, and, if necessary, remove it from the exhaust stream. Briefly, what are some common exhaust-gas and air-pollution-control technologies used in the process industries? [0:20]
  • How would a process engineer go about selecting the right technology for controlling NOX and particulate at his or her facility? [6:43]
  • When should a processor reassess their pollution control technologies? What is a proactive approach that is manageable? [8:05]
  • Can you tell me a little bit about the testing that should be done on emissions control systems? If they have planned for regular testing as a part of their preventive maintenance, what are some good ways to get that testing accomplished? [9:50]
  • Are the requirements for testing this equipment widely known? [10:42]
