• Indicators showed position tags of valve at 90%.
  • Reformer tube temperature dropped slowly to 750° from 785° (Low alarm threshold  was set at 650°).
  • Reformer draft opening dropped from 98% to 42%.

How SAM GUARD Helped

  • SAM GUARD began to send alerts 100° prior to the set threshold.
  • Thanks to the early alerts, which combined all indicators along with other aspects of the plant, measures were taken to avoid equipment failure and major emergency shutdown.


  • SAM GUARD provided an accurate alert that prevented a major failure of the pump.
  • By fixing a small problem ahead of time, a greater problem was eliminated that would have caused shutdown and lost production.
