OCI NITROGEN (CHEMELOT SITE, THE NETHERLANDS)
  • Project: OCI Nitrogen
  • Industry: Various
  • Location: Keppel shipyard, Singapore

After thorough field testing by Sitech Technical Services BV, Humidur was selected as the only product withstanding the conditions on the steel infrastructure of the OCI Nitrogen old plant, located on the Chemelot chemical park in Geleen, The Netherlands.

After surface preparation by means of wire brush (minimum surface preparation to St 2 – ISO 8501), Humidur was applied in one or two coats by brush. The structures that require corrosion treatment are supporting piperacks, stairwells and handrails in open air and inside the old plant. The applications in open air were done without the need for climatization in often cold and humid conditions. A challenge during the project was the continuous impact of both steam exhaust and nitrate rich air on the structure, which cause accelerated corrosion and affect most traditional coatings.
