Project HeraCless focuses on the production of clean, green and circular steel - the new Direct Reduced Iron (DRI) plant will be a key part of this. The environmental installation at the pellet factory (PEFA) is one of the biggest steps in the other programme, Roadmap Plus, which aims to reduce emissions of particulate matter, lead and heavy metals, and thus realise a positive effect on the immediate environment. The sheer size of the environmental installation (approximately 170 metres long, 45 metres wide and 110 metres high at its highest point) makes it a literal main feature. The dedusting installation, part of the new environmental installation, arrived in sections at the Tata Steel site in mid-2023 and is expected to be operational in the same year. The environmental installation should reduce emissions of heavy metals, lead and dust from the pellet plant by approximately 80 percent.
Iv is playing a major role in these two improvement programmes and together with Tata Steel, has developed and finalised the designs for the environmental installation. From 2025, the dedusting installation will work in conjunction with the DeNOx installation. The deduster consists of no less than 6,000 10-metre bag filters, equivalent to 60 kilometres of filter cloth.
The PEFA (Pellet Factory) produces round balls (pellets) from iron ore. These pellets are a critical raw material for the production of pig iron. In addition to carbon dioxide (CO₂), significant amounts of nitrogen (N2) are released during the entire production process.
Nitrogen oxide (NOx) emissions must also be significantly reduced. The dedusting installation will be directly connected to the PEFA and will capture a large part of the heavy metals, flue gases and dust through 'filtering'. The DeNOx installation will primarily reduce nitrogen emissions through 'washing' and 'scrubbing'. The water from the dedusting installation will then be transported to a new (to be built) water treatment plant.
