Renewables for industryProject Calix Zero Emissions Steel Technology (ZESTY) pre-FEED / FEED Study
This is a pre-FEED/Basis of Design study for using Calix’s Zero Emissions Steel Technology to process 30,000 tonne per annum hydrogen-direct reduced iron commercial demonstration plant.
The Pre-FEED study into a demonstration scale plant with a nominal output of 30,000 TPA DRI using the Calix ZESTY process technology has been undertaken. This study aims to propose an initial Basis of Design (BoD) for a ZESTY plant whilst also considering possible Australian locations for a plant.
Potential sites upon which a demonstration scale plant could be located where examined and compared on eleven different criteria with the results captured in Table 3 – Plant Site Selection Criteria for ZESTY Demo Plant H-DRI 30,000 TPA (page 15). The resultant analysis provided three leading candidates being: Port Hedland in Western Australia, Port Kembla in New South Wales and Port Augusta/Whyalla in South Australia. All three options will be further examined in the future FEED study. The pre-FEED study also considered potential process flowsheets for Haematite/Goethite and Magnetite fine ores with the
primary difference between the two flowsheets being a pre-oxidation step to activate the magnetite
prior to reduction. The requirement for a pre-oxidation step is being tested as part of the pilot test work
