Belzona® Rectifies Leakage Problem In A Bioreactor Clarifier

 
 

Industry:

Petrochemical (PETR)

 
 

Application:

Tanks and Chemical Containment Areas (TCC)

 
 

Customer Location:

Petrol Refinery in Thailand

 
 

Application Date:

January and February, 1996

 
 

Application Situation:

Steel bioreactor clarifier tank 100' diameter (31m) with a concrete bottom, split into six segments

 
 

Problem:

Bottom of the tank had to be made waterproof and an expansion joint incorporated where the concrete floor meets the steel tank wall.

 
 

Products:

Belzona® 5811 (Immersion Grade)

Belzona® 4111 (Magma-Quartz)

Belzona® 2221 (MP Fluid Elastomer)

 

Substrate:

Concrete and Steel

 
 

Application Method:

Application carried out in accordance with Belzona® Know-How Leaflets TCC-9, TCC-11, TCC-12 and TCC-15

 
 

Belzona Facts:

Replacement of the tank was too expensive even to consider. Other options that were considered included using a glass flake system to coat the tank and welding a steel bottom onto the walls of the tank. The cost of this method would have been about £370,000. The Belzona® solution cost only £80,000, a saving of almost £300,000, and took a fraction of the time estimated for the welded repair.
