    One of the leading climate mitigation technologies is carbon capture. Separation of carbon from power plant flue gases using advanced technology is a promising method to pave the way towards a sustainable world. Solvent based carbon capture is one of the most researched and close to commercialisation technologies which has the capability to be designed for new power plants or retrofitted to existing power plant fleet. The technology is based on temperature swing process and therefore involves use of energy and thus reduction power plant output. The reduction in the use of energy in the capture process is one of the main aims of the research.

    The project involves using world class equipment at the PACT facilities (http://www.pact.ac.uk/) at the University of Sheffield to perform state of the art research. Energy and environmental performance assessment of the capture process under varying operational conditions will be assessed by using online and offline measurement techniques. The impact of different species in the flue gas such as CO, NOx, particulates, etc. on the solvent degradation and emissions from the capture process will be studied.

    Molecular modelling and simulation for solid adsorbents for industrial Carbon Capture

    Supervisor: Prof Meihong Wang, Prof Mohamed Pourkashanian

    Carbon capture and storage (CCS) is viewed as a key technology to reduce anthropogenic CO2 emissions worldwide.   In addition to solvent based carbon capture, solid adsorbents for carbon capture have attracted researchers’ interest.   This project aims to predict the technical performance of solid adsorbents using advanced molecular modelling and simulation.   In this way, we can give feedback to chemists carrying out synthesis of solid adsorbents directly, rather than waiting for pilot plant tests.  Molecular modelling and simulation can also predict physical and chemical properties for these solid adsorbents, therefore provide accurate information for process simulation.

    Carbon capture and storage (CCS) is viewed as a key technology to reduce anthropogenic CO2 emissions worldwide.   In addition to solvent based carbon capture, solid adsorbents for carbon capture have attracted researchers’ interest.   This project aims to evaluate the technical and economic performance of carbon capture process using solid adsorbents based on process simulation (such as Aspen Adsorption).  We hope to compare this technology with solvent based carbon capture systematically so that we can provide evidence for policy makers

  • Experimental optimization of post combustion carbon capture process for climate change mitigation

    Process simulation, system identification, model reduction and process control of Solvent based Carbon Capture for power plants

    Supervisor: Prof Meihong Wang, Prof Mohamed Pourkashanian, Dr Kevin Hughes

    Carbon capture and storage (CCS) is viewed as a key technology to reduce anthropogenic CO2 emissions worldwide.   We have pilot plants or even large scale commercial deployment of solvent based carbon capture plants.  However it is still a technical challenge to operate and control such plants (esp. when it is integrated with various power plants).  This project aims to develop (transfer function or state space) models using system identification (with experimental data from our pilot plant or our developed models for solvent based carbon capture).   An alternative is to build reduced model from detail first principle models for solvent based carbon capture. The models will be further used for process control.

    Performance assessment and flexibility study of natural gas-fired Power Plants integrated with intensified solvent based Carbon Capture

    Supervisor: Supervisors: Prof Meihong Wang, Prof Mohamed Pourkashanian, Prof Lin Ma

    Natural gas-fired (mainly combined cycle gas turbine) power plants are becoming increasingly popular due to its cleaner nature.   Solvent based carbon capture is the most matured technology for commercial deployment in natural gas-fired power plants. The challenges are: high capital cost and energy consumption for solvent regeneration. The new solution is to apply process intensification technology for solvent based carbon capture. This project aims to evaluate solvent based intensified carbon capture for gas-fired power plants based on process modelling and simulation.  The questions to be answered are: size of the equipment such as Absorber and Stripper, capital costs, operating costs, energy consumption to capture per tonne of CO2 and operational flexibility.
