- thyssenkrupp Polysius is developing a flash calcination plant using Electric Arc Calciner technology.
- The pilot plant in Mo i Rana, Norway, will have a capacity of 120 tons per day.
- Material tests are conducted to assess thermal behavior under electric conditions.
- The project aims to modernize lime production, enhancing efficiency and reducing emissions.
Project Overview
thyssenkrupp Polysius has been tasked by SMA Mineral to develop the first industrial flash calcination plant using Electric Arc Calciner (EAC) technology. The project is in the pre-engineering phase, focusing on the conceptual design and preliminary layout of preheating and cooling systems, integrating SaltX Technology’s EAC process.
Objectives
This initiative is part of SMA Mineral’s modernization program aimed at increasing efficiency, reducing emissions, and enhancing the competitiveness of Nordic lime production. The project also supports the domestic production of lime and fossil-free aviation fuel, crucial for industrial development and national preparedness.
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 essential for the planned pilot plant, which will have a capacity of 120 tons per day, marking a significant step toward a potential full-scale facility.
Material Testing
In collaboration with thyssenkrupp Polysius, SMA Mineral has initiated and financed material tests to evaluate thermal behavior inside the cyclone preheater under electric process conditions. These tests, supported by SaltX Technology, provide critical data to validate and refine 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, enabling a future-ready production chain that enhances industrial competitiveness and regional resilience.
