| Abstract Scope |
In the future, bio-carbon use and carbon capture is expected to be more common in the ferroalloys industry. This creates possibilities for utilisation of waste heat through industrial symbiosis with industries that require lower quality energy.
This paper presents an overview of some of the concepts that present potential energy savings in the ferroalloys industry, and the potential for heat and material integration between ferroalloys production and biorefinery applications.
A conceptual flowsheet model has been developed and used to evaluate the combined effects of different unit operations on the overall energy consumption of the integrated plant.
Evaluation of these concepts: considering bio-char production and carbon capture as integral parts of metal production, potential energy savings of 38-40% seems plausible in the silicon industry, and 36% in manganese. |
