Carbon capture and storage:

Carbon capture and storage

  • Molecular modelling and simulation for solid adsorbents for industrial Carbon Capture

    Combined Cycle Gas Turbine – CCS; experiment and modelling

    Supervisor: Professor Mohamed Pourkashanian, Professor Lin Ma and Dr Kevin Hughes

    This project will combine an experimental and modelling study of a combined cycle gas turbine with CCS. A Turbec T100 gas turbine will be modified to allow the investigation of the effect of exhaust gas recycle and or steam injection on its performance, with measurement of power output and exhaust gas emissions. The exhaust is connected to a post combustion amine capture plant to remove CO2 from the exhaust gas stream, and the efficiency of this as a function of turbine operating conditions will also be investigated. This will be complemented by process simulation with the gPROMS or ASPEN software package to investigate the overall system performance and economics.

  • Molecular modelling and simulation for solid adsorbents for industrial Carbon Capture

    Pilot plant experimental work – 250 kW PACT facility – zero emission strategies – coal- biomass and bio-CCS

    Supervisor: Professor Mohamed Pourkashanian, Dr W Nimmo

    Fossil fuel will remain a significant contributor to power generation around the world as countries develop and realise their economic and social potentials through industrial growth and increase in people’s standard of living. For example, coal remains a principal fuel for electricity generation (~40% of the world market) and contributes ~43% of CO2 emissions from the combustion of all fossil fuels. Therefore, in order to meet CO2 reduction targets, the urgency of developing, demonstrating, and deploying Carbon Capture and Storage (CCS) technologies is clear, supported by the recently released Intergovernmental Panel on Climate Change report.

    Oxyfuel combustion is one of the front running technologies for CO2 capture in power generation and energy intensive industries, as recognised by the UK government’s recent announcement to fund the FEED study for the White Rose Partnership project as part of the £1bn DECC competition for CCS commercialisation. Displacement of coal by biomass with CCS is a method of gaining benefits from negative CO2 emissions.

    The project will involve detailed experimental work performed on the 250kW combustion test facility associated with funded projects in the area of oxyfuel combustion. Coal and biomass fuels will be used and flame analysis methods will be employed; heat flux, temperature, chemical species and emissions. The effect of flue gas recycle conditions on flame characteristics and emissions will also be investigated.

    Oxy-fuel Power plant design

    Supervisor: Professor Mohamed Pourkashanian, Dr W Nimmo

    Conceptual designs for coal-fired power plants seek improved methods of heat and process integration to improve overall plant efficiency using conventional technologies for power generation and oxygen production. At the same time, it is necessary to ensure operating flexibility (to provide dispatchable power to meet the challenge of the intermittency of renewables3), fuel flexibility to use the cheapest fuels (including biomass to further reduce CO2 emissions), plant/component reliability and the production of consistent transport-ready CO2 are not compromised.

    Areas for investigation include; System integration, Air separation unit integration, CO2 processing unit integration, Energy integration, Efficiency, low grade heat integration, fuel drying potential.

    CFD modelling and advanced burner designs

    Supervisor: Professor Mohamed Pourkashanian, Professor Lin Ma, Professor Derek Ingham

    A substantial amount of current activity on oxyfuel combustion capture is still at the conceptual design stage, encompassing a broad range of fuels and power systems, including the development of alternative system configurations that maximize overall efficiency and minimize estimated capital and operating costs. Many of the designs include advanced component technologies, next generation burners and heat integration schemes that do not currently exist, but which illustrate the potential for process improvements. Next-generation combustors for oxyfuel are moving towards extreme conditions and novel combustion concepts are being developed that hold promise for even lower-cost capture systems.

    The project will involve the design of novel hybrid burners for coal-biomass-air-oxy combustion flexibility in real plant operation. Prototype scaled burners at 250kW may be tested and validated alongside funded projects on experimental combustion test facilities.
