With this Steam Project our customer invests in an innovative technology to convert water-based waste into energy. This steam technology is an extension to their plant where chemicals are produced for the purpose of clothing, furniture, household products and construction materials. The new installation will transform the production’s waste into steam. This steam will be used as an energy source in the existing production plant. This process results in an annual reduction of ca. 140,000 metric tons CO2 emissions, 0.9 petajoule of energy and avoiding the release of 11 million kilograms of salt residue into the surface water. This CO2 reduction equals taking 31.000 cars of the road for a year. Gpi delivered four tanks for this innovative project: a 70 tons 1553 m³ Aerobic biofeed Surge Tank, a 55 tons 1108 m³ Anaerobic Biofeed Surge Tank, a 23 tons 500 m³ Arcru Storage Tank and a 4 tons 48 m³ Urea Storage tank. All build from duplex stainless steel (LDX 2101) and designed and produced according to NEN-EN 14015 and PGS29 standards. The specified pressure of + 500mbarg was a major challenge for both design and production. This resulted in substantial material thicknesses and extra heavy anchoring of the tanks. To give a glimpse into the transportation process of those giant tanks we created drone footage when they left the XL production site.
