Heat exchangers: operating in Ammonia oxidation plants

  • Perform an important role for heat recovery and steam production
  • Operating fairly close to engineering design temperature limits (eg. Creep)
  • Longevity & sustainable performance desired
  • Time consuming to maintain / repair / replace
  • Precious metals deposit on heat exchangers
  • Other process materials can also deposit (eg. Debris)
  • During operation thermal efficiency is progressively reduced with the following effects:
  • Increased component & equipment temperatures locally and downstream
  • Reduced steam production

Industrial Cleaning – Non-Destructive / Non-Acidic 

  • Safe, Effective & Environmentally Friendly cleaning methods
  • The use of patent pending Non-Acidic cleaning technologies and high pressure washing solutions to remove robust surface deposits and maximise plant efficiencies.
  • Non-acidic cleaning mitigates risk of damage to operational plant and equipment and is a much safer option than alternatives.

Industrial Cleaning – Destructive / Acidic

  • Using a concentrated acidic solution to aggressively break surface deposits away from steel tubes / shells to maximise PGM recovery.

Industrial Cleaning – Recovery from other Vessels

  • PGM’s can also collect in downstream vessels including storage tanks
  • Safe working methodologies & risk assessments to assist plants
  • Experienced team & ability to efficiently recover, filter, neutralise and prepare PGM bearing materials ready for shipment.

Precious Metal Recovery

  • Collection, filtration & packaging of surface contamination resulting from the industrial clean.
  • Packaged material may be shipped to a facility for refining & recovery of platinum group metals (PGMs).
  • BDB (URSG) have refining facilities in the USA & Norway, offering clients a “one stop” option.
