OVERVIEW: The customer required repairs to be carried to their Chlorine plant whilst still operating.
Our range of solvent free and low odour RF 500 and RD 900 systems were the perfect solution with excellent moisture tolerant properties (ideal for water blasting) and extreme chemical resistance. An additional benefit is that the coating colour changes from orange to red when in contact with 98% sulphuric acid for easy identification and immediate clean up.
INDUSTRY
ENVIRONMENT
Highly corrosive range of chemicals including sulphuric acid, hot caustic, brine and chlorine
SUBSTRATE
Concrete Bunds and Floors in Chlorine Plant
CHALLENGE
The Chlorine Plant had been in operation for over 20 years with little maintenance to concrete floors or bunds. Large areas of contaminated and spalling concrete created slip, trip and chemical pools which were safety hazards. The task was to create a safer work environment, stop ground contamination, and to reinstating all floors and bunds to new during a shut down.
SOLUTION
Plant was divided into 4 key areas:
Brine Filter Press– The elevated concrete floor, bund walls and plinths were cracked and the concrete was corroded by the hot salty water and caustic.
BIX column area – This area was largely corroded requiring massive repairs to floors and plinths.
Acid Bunds – Previous coatings were failing requiring immediate repairs.
General Floors – Walkways and pump plinths were treated last to allow access to the plant. Since the repairs were carried out concurrently with an operating plant as well as during a major shutdown, we recommended our range of solvent free and low odour RF 500 and RD 900 systems with excellent moisture tolerant properties (ideal for water blasting) and extreme chemical resistance.
OUTCOME
Repairs to Coating of Bund Area provided:
A clean and safe work environment with improved light reflection and reduced slip hazards
All paths with potential leaks had been sealed to improve worker safety
Expected life is 10+ years
An additional benefit to client is the coating colour, which changes from orange to red when in contact with 98% sulphuric acid for easy identification and immediate clean up
