Cleaning and Rejuvenation Processes

CoaLogix applies Cleaning & Rejuvenation processes to lightly or severely
plugged or blinded catalyst that may have limited deactivation from catalyst
poisons, or as part of the full ReGen™ process for severely poisoned and
deactivated catalyst. The Cleaning & Rejuvenation processes eliminate
materials physically plugging the catalyst in order to improve NO_x reduction
efficiency and remove poisons, thereby extending the useful life of the catalyst.

Ultrasonic Cleaning:
Our patented ultrasonic cleaning technique deep cleans the catalyst pores
to remove physical and microscopic pluggage.   

Rejuvenation:
Catalyst modules are soaked, washed and rinsed in a series of temperature
and pH-controlled baths that eliminate physical restrictions (e.g., blinding layers,
large particle and fly ash) and remove catalyst poisons contributing to catalyst
deactivation such as arsenic, phosphorus, thallium, sodium, potassium and
calcium. The catalyst is then prepared for regeneration, if required.

Benefits of CoaLogix Cleaning & Rejuvenation

• Extends useful catalyst life
• Optimizes NO_X reduction capability
• Guarantees:
  > No physical damage to the catalyst
  > No loss of structural integrity
  > No loss in remaining activity

Limitations

CoaLogix's Cleaning & Rejuvenation processes cannot cure reutilization,
erosion, abrasion or other physical and/or structural damage to the catalyst,
or restore catalyst activity levels. For full restoration of catalyst activity,
our regeneration process may be applied.
