Techno-Economic Study of Power generation from Coal/Biomass with Carbon Capture and Storage

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

Demand for energy supply in the present global environment is continuously increasing with the growth of population and economic development. This poses problems both in terms of sustainability and carbon emissions. These may be mitigated by the use of biomass feedstocks, either alone or mixed with coal, along with the implementation of carbon capture and storage. The aim of this project is to use the IECM and gPROMS process modelling package to construct techno-economic process models of the use of biomass and coal/biomass mixtures in power generation, specifically, but not exclusively in the context of feedstock gasification for use in Integrated Gasification Combined Cycle (IGCC) power plants.

Techno-economic investigation of a Syngas – Combined Cycle Gas Turbine – Amine Capture Plant

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

This project will comprise a process modelling study of syngas production in conjunction with a combined cycle gas turbine with CCS using an amine capture plant. Process modelling, using either ASPEN, gPROMS or the SimSci software packages will be used to investigate the technical performance and economics of this combined system, allowing its optimisation from a performance and/or economic viewpoint. This will draw on the experimental data available from a pilot scale operation of a Turbec T100 gas turbine connected to an Amine capture plant at the UKCCSRC PACT facilities.

Low cost, energy efficient biomethane production from landfill gas or biogas

Supervisor: Professor Mohamed Pourkashanian, Dr W Nimmo and Professor Lin Ma

Biomethane can be produced from biogas or landfill gas in a fairly simple water scrubbing system. This process has been used on large scale biogas plants but the optimal operation has not been fully investigated. Existing validated models will be used to design the process conditions to give optimal conversion to the required quality of biomethane depending on the application (vehicle use, CHP, grid injection) such as operating pressure, water and gas flow rates and packing media. This will lead onto a techno-economic assessment of the process and its integration into the larger AD energy system. The student will benefit from excellent laboratory and analytical facilities and links with industry through our collaborative work and have access to micro-AD development sites in the UK where pilot scale test facilities can be developed.

Next generation CCS technology for combined cycle gas turbine system

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

Carbon Capture and Storage (CCS) from CCGT (combine cycle gas turbine) systems is an emerging near-zero emission technology that can applied to new and retrofit CCGT power plants, leading to a substantial reduction in carbon emission to the atmosphere in power generation industry. This project will model the performance and/or techno‐economic assessment for full scale power plants that employ the next generation CCS technologies. Plant process simulation software packages, such as the gCCS and Aspen will be employed as a platform to develop plant simulation tools. CFD simulations will be used for oxyfuel combustion modelling with exhaust gas recirculation (EGR), and linked to the process modelling. The output from this project may be used for future CCS power plant design optimisation, demonstration and/or staff training.

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.

Dynamic simulation of load-following power plants integrated with CO2 capture technologies

Supervisor: Professor Mohamed Pourkashanian, Dr Kevin Hughes, Professor Lin Ma and Dr Maria Elena Diego de Paz

Flexible operation of fossil fuel power plants is becoming a hot topic in the energy generation sector due to the expected increase of intrinsically intermittent renewable technologies in the energy mix in the near future. This flexible operation mode of the energy systems is challenging, especially when these plants are coupled to CO2 capture technologies. This study aims at investigating the dynamic behavior of natural gas fired power plants integrated with a post-combustion amine CO2 capture system, using process simulation tools such as Aspen Hysys and/or gCCS (gPROMS). The performance of the whole system will be assessed under dynamic conditions. Different integration options between the power plant and the capture system will be studied and analysed from a techno-economic perspective.
