Specialist Application Areas

  • Internal surface of H2S/CO2 carbon steel absorbers exposed to hot amine solutions. Amines such as MEA, DEA, MDEA, DGA and ADIP are used in this process and these can become very corrosive to carbon steel under certain conditions. DuraPol UHT has proven long term resistance to all amines and so is the first choice for protecting absorbers.
  • Once fully saturated with H2S/CO2, amines are eventually recyled in regenerators operating at temperatures in the range of 120-130oC. DuraPol UHT has a long proven history of protecting regenerators and their associated reboilers.
  • Acid storage tanks, railcars and concrete secondary containment areas as well as acid neutralisation pits and tanks.
  • Tanks storing caustic at elevated temperatures.
  • Subsea duplex spools operating at high temperatures with cathodic protection.
  • Tanks and process vessels constructed from stainless steel or protected by alloy cladding are now being replaced with DuraPol coated carbon steel at a fraction of the cost.
  • Heat exchanger tube sheets, tubes and shell internals.
  • Evaporators and deaerators operating at close to 110oC are being routinely coated. Very first deaerators have now been in service for nearly 10 years without any coating damage.
  • Hydrocarbon/water separators operating at pressures up to 2000 psi and temperatures up to 150oC.

These are just a few of the many areas where DuraPol coatings have been key to successful plant operation.
