Ethylene Oxide Plant Explosion Lesson Learned

March 31, 2017 by  
Filed under Articles

An exterior fire is 1 of the most hazardous situations that can manifest in an ethylene oxide (EO) plant for the reason that of the probable for EO decomposition. Even with very good water spray methods and very well-insulated tools, flame impingement from an exterior fire can enhance piping and vessel wall temperatures to EO decomposition temperature in a limited time period of time. If this occurs, an interior explosion can manifest.

Pump Seal Leak Hearth

An ethylene oxide pump seal leak is constantly a substantial incident for the reason that of staff publicity worries. Nonetheless, if a pump seal leak ignites, the success can be catastrophic.

A European ethylene oxide generation plant had an EO pump seal leak that was ignited by get in touch with with warm pump elements.The flame from the pump seal fire impinged on an uninsulated minimum amount movement return line, producing evaporation of the EO in that line. Ongoing warmth input from the flame impingement resulted in a decomposition in the minimum amount movement line. The decomposition reaction propagated into the EO purification column reflux drum, in which an explosion transpired. The reflux drum and its affiliated distillation column had been ruined. This incident resulted in 4 fatalities. The plant was intensely damaged and out of operation for 4 months.

Hearth Around Distillation Column

An ethylene oxide producer in the US had a rupture of an EO compressor cylinder. This resulted in a massive fire, which engulfed the EO distillation column. The resulting temperature enhance on the area of the column and in the contained EO resulted in an interior explosion and substantial injury.

Flange Hearth whilst Plant was Down

A European ethylene oxide producer expert a flange leak in the EO distillation portion. The plant had been shut down, but nonetheless contained an inventory of EO. The flange leak resulted in a fire and the flame impinged on a procedure line containing EO. The warmth brought about an EO decomposition reaction to be initiated in the line. The decomposition propagated down the line and into a distillation column. The column head was torn off and thrown about a hundred ft. Substantial and modest elements of the column jacket had been scattered in excess of a 2000-foot radius. Only seven minutes elapsed between the begin of the unit fire and the column explosion.

Critical worries with regards to pumps and compressors in EO services are

  • the probable for superior temperatures if mechanical energy is not dissipated and
  • the probable for a fire thanks to seal leaks.

A very good case in point of failure to take out mechanical energy is a blocked pump discharge. The two incidents described here are very good illustrations of the success of functioning an ethylene oxide pump lifeless headed. The pump seal leak fire is a very good case in point of the probable consequences of a seal leak fire.

Decomposition in Reflux Pump Propagates to Reflux Drum and Tower

A European ethylene oxide producer had been getting challenges with the EO purification column reflux pump in excess of-rushing. There had been also instrumentation challenges with the level controller on the reflux drum, and the incident was activated by the reflux control valve failing closed. The reflux pump operated lifeless headed from the level control valve, producing temperature in the pump to rise, vaporizing EO and producing a decomposition reaction. The decomposition propagated via the pump suction line into the reflux vessel in which an explosion transpired. Shortly afterward the EO purification column exploded. This explosion resulted in 4 fatalities. The plant was intensely damaged and out of operation for 4 months

Ethylene Oxide Decomposition in Blocked-in Pump

A US ethylene oxide producer used superior-velocity centrifugal pumps to feed EO to two ethylene glycol models. The plant had a frequent spare feed pump for the two glycol models.The spare pump was ordinarily held cleared of EO, pressured up with 200 psig nitrogen and left with the suction and double discharge valves blocked in.

A modest sum of EO leaked via two blocked discharge valves into the pump. An electrical method malfunction brought about the superior-velocity centrifugal pump’s electrical motor to begin. The pump ran blocked in for approximately 10 minutes until eventually the seal spot of the pump arrived at EO decomposition temperature and the pump exploded.

The decomposition of the .6 lb. of EO created in excess of 450,000 lbs of pressure and brought about the failure of twelve,3⁄4″ stainless steel nuts and bolts. The upper portion of the vertical centrifugal pump and the motor (approximately one thousand lb.) had been released sixty ft in the air. The pump and motor landed on the discharge piping of an additional EO feed pump that was functioning at 750 psig, pumping 80 gpm of EO Fortuitously the piping did not are unsuccessful.

Heartburn hurts! Not only that, but when someone has their first attack, it’s scary. After all, in most people’s minds, all of that pain in the chest can only mean a heart attack. More seasoned veterans of heartburn attacks, however, know that heartburn has nothing to do with the heart and everything to do with the stomach and the esophagus. They realize that when stomach acid splashes back up into their esophagus, it causes the pain of the condition known as heartburn or acid reflux. Knowing the cause is only part of the battle, though. What sufferers want to know most is how to get rid of heartburn.

Most heartburn pain is easy to conquer. Antacids will take care of the majority of episodes in short order. In fact, they break down in the body so easily that they bring almost instant relief. But what if an attack hits you and you don’t have any antacids in the house? There are home remedies that you can make out of the ingredients in your kitchen that will do in a pinch. Some of these fixes include mixing apple cider vinegar with honey and baking soda, eating a handful of raw almonds, or two tablespoons of straight cider vinegar. People swear these remedies work, but in some cases the cure may be worse than the affliction.

Some of the best ways to eliminate heartburn altogether are as follows:

1. Sit up straight – no more flopping down on the couch after a huge meal. Sitting up will allow the stomach acid to stay where it belongs causing you no problems.

2. Avoid tight clothing – anything that compresses your stomach may push acid back into your esophagus.

3. Lose weight – having excess pounds can put pressure on the stomach causing it to release acid back into the esophagus.

4. Stop smoking – smoking causes the production of excess stomach acid and also weakens the muscle at the end of the esophagus allowing acid to escape back up it.

Knowing how to cure heartburn will usually do the trick. However, if you continue to have problems or the episodes become more frequent and more severe, contact your doctor.
