DTU Chemical Engineering seeks qualified candidates for the vacant PhD position listed below. The project will be conducted in the CHEC Research Centre at DTU Chemical Engineering. CHEC is internationally recognized with respect to research in combustion, industrial high temperature processes, gasification, and catalysis.

CFD modeling of NOx formation and control in mineral processing
The ability to predict and control emissions of nitrogen oxides (NOx) is important for optimizing processes for production of stone wool and cement. Both processes involve high temperatures (>1500°C), which promote NO formation. Nitric oxide can subsequently be reduced by in-situ control methods, such as reburning and/or SNCR, at lower temperatures (800-1200°C). The companies FLSmidth and ROCKWOOL both have a need for the capability to simulate NOx formation and reduction in high-temperature processes for mineral processing using CFD. The aim of this project is to develop and implement NOx models into CFD and validate the resulting model by comparison with experimental data from both small scale and full scale. This will allow ROCKWOOL and FLSmidth to utilize the model to support design and operational initiatives to control NOx effectively.

Responsibilities and tasks
The candidate will develop and validate simplified reactions schemes for formation and consumption of NOx, implement these schemes in CFD, and conduct CFD simulations of industrial scale facilities for cement and stonewool production. The candidate is expected to collaborate with the industrial partners. The position may involve co-supervision of MSc students.
