thyssenkrupp Polysius Aids SMA Mineral in EAC Pilot Plant Design in Norway

Key highlights
  • The pilot plant will have a capacity of 120 tons per day.
  • The project is part of a modernization program to increase efficiency and reduce emissions.
  • Material tests are conducted to assess thermal behavior under electric conditions.
  • The initiative aims to create a fully electric and emission-free quicklime production.

Project Overview

Polysius has been tasked by SMA Mineral to develop the first industrial flash calcination plant using Electric Arc Calciner (EAC) technology. The focus is on designing preheating and cooling systems and integrating SaltX Technology’s EAC process.

Modernization Goals

This initiative is part of SMA Mineral’s modernization program aimed at enhancing efficiency, reducing emissions, and boosting the competitiveness of Nordic lime production. The project is crucial for domestic lime production and future fossil-free aviation fuel.

Technical Development

thyssenkrupp Polysius and SaltX are working on a multi-stage cyclone preheater solution with cyclone-flash cooling, tailored to the Mo i Rana site in Norway. This pre-engineering phase is foundational for a pilot plant with a 120 tons per day capacity, paving the way for a potential full-scale facility.

Material Testing

In collaboration with thyssenkrupp Polysius, SMA Mineral has initiated material tests to evaluate thermal behavior in the cyclone preheater under electric conditions. These tests, supported by SaltX Technology, are essential for refining key process parameters for the pilot facility.

Future Implications

The FEED study by thyssenkrupp Polysius strengthens its role as a key technology partner in the ZEQL project, supporting the transition to fully electric and emission-free quicklime production. This partnership accelerates the modernization of the lime industry, enhancing industrial competitiveness and regional resilience.
