Blasing through a wall of solid coke. Crude furnace A crude heater at Atofna’s Port Arthur, Texas facility had unexpectedly coked solid. With zero fow, traditional seam-air de-coking procedures would be impossible. Fortunately, we had extensive experience in coke removal. Since the tubes were totally blocked, the engineering department concluded that Hydrokinetics ofered the only viable solution. If we couldn’t do it, it couldn’t be done. We dispatched our crew and commenced the Hydrokinetics process. After 15 minutes, we noticed signifcant pressure spikes at 1,100 PSI, followed by a return to normal dischar ge pressure. This happened fve times in rapid succession. We then noticed fow coming through the vacuum line at the outlet end with a considerable amount of coke solids and crude resid
