Problem • 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 to 42% from 98%. 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. Value • 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.
