Casale - SCHMIDTSCHE SCHACK process boilers to be installed at Fertiberia ammonia plant

Published by , Editor
World Fertilizer,

Casale has been contracted by Fertiberia to provide three high-pressure process boilers (RG boilers) to replace the existing units placed downstream of the secondary reformer at the ammonia plant at Palos in Spain. The new boilers will feature the Casale - SCHMIDTSCHE SCHACK design.

The plant was built in the early 1970s under license by MW Kellogg licence. The old boilers are based on the traditional design featuring vertical layout and bayonet-type tubes with water flowing inside the tubes and the hot gas shell side for the first two boilers (101-C A/B) and process gas in the tubes for the second boiler (102-C).

Drawing upon SCHMIDTSCHE SCHACK | ARVOS' SCHMIDT’SCHE® Double Tube & Oval Header technology platform the new design allows the realisation of the following advantages:

  • No change in plant configuration.
  • Re-use of existing foundations.
  • Easy and fast installation, minimising the downtime required.
  • Water-cooled tube sheet, no use of any refractory.
  • No sludge/scale deposits.
  • Low tube skin temperature.
  • No crevice corrosion.
  • Thermal expansion compensation.
  • Trouble-free operation and easy maintenance.

The new boilers for Fertiberia will be designed to also meet the future conditions for when the plant will be operated with the addition of green hydrogen.

Three in one: Knight Material Technologies leverages the expertise from three companies for sulfuric acid protection

Sulfuric acid poses a persistent threat to the structural integrity of critical equipment used in the fertilizer industry. For corrosion protection, fertilizer producers can rely on a single source using fluoropolymers, dual laminates and acid-resistant mortars and bricks. Case studies can supply credible examples of the solution’s long-lasting success in challenging applications.
