Project achievements
It was found that the supported amine adsorbent in a system with counter current flow of adsorbent and gas inside the adsorber and regenerator achieved the best performance. If heat integration is carried out between the adsorbent streams leaving the adsorber and regenerator, there is a potential for a significant saving in energy consumption compared to the amine absorption system. Practical issues that make the implementation of moving bed adsorption systems difficult were also explored and possible solutions to overcome these issues were proposed.
Student attractions of the EngD Centre
An EngD offers a huge amount of experience in carrying out a complex research project. It offers the student a great understanding of industrial needs, issues faced in industry and experience for work carried out by an engineering company. The link between the university and the industrial sponsor allows many opportunities as the student can take advantage of the expertise of both organisations. In addition there are many opportunities for personal development through training courses and for participation in conferences and summer-schools. The enhanced stipend and budget allocated to projects are also very attractive compared to other doctoral programs.
Research summary
In this project, moving bed adsorption processes for CO2 capture were studied primarily using mathematical models. This technology was compared to more developed technology such as fixed bed adsorption processes and amine absorption processes for CO2 capture. The performance of technologies was assessed based on CO2 recovery, CO2 purity and energy consumption for adsorbent regeneration. The research focused on three types of adsorbents that were used inside different configurations of moving bed adsorption systems.
