Ammonia and Methanol are produced from natural gas utilizing very similar processing techniques. These processes involve the Natural Gas Feed, Primary Reformer, Shift Converters and Recycle Streams. Since the effluent from the first stage becomes the feed to the second stage, variations of the sample compositions that occur in all of the processes need to be closely monitored, quickly analyzed and controlled.
Extrel MAX300-RTG Process Mass Spectrometers analyze all Ammonia production process streams (or Methanol process streams) allowing control over the critical process parameters.
Documented reports from Extrels customers indicate savings of energy, reduction of process variance and a substantial increase in production when an Extrel Mass Spectrometer is used in a closed loop control scheme. Recognized as the leader for Ammonia Production Control, Extrel is an approved mass spectrometer supplier for ammonia process licensors worldwide.
