Why is it necessary to reduce Hg in crude and condensates?

  1. Hg and Hg salts are generally toxic
  2. Hg is corrosive to aluminum heat exchangers in natural gas and petrochemical facilities, as well as brass
  3. Hg°, elemental mercury, will coat metal surfaces requiring special handling upon equipment decommissioning
  4. Hg in refining rapidly and irreversibly deactivates hydrotreating catalyst
  5. Hg° will accumulate and pool in cooler, lower places such as bleeder piping on elevated vessels, knockout drums and overhead receivers
  6. Hg in metals poses risks for workers during maintenance

Mercury in Crude is Not Uncommon

One should consider licensing MERCAWAYSM technology to reduce mercury in crude or condensate.
