The objective of this project was to investigate the impact on performance and cost of coal based gasification plant of the installation
and operation of CO2 capture equipment at high pressure. This involved:
Establishing three design cases. A medium pressure CO2-in Base Case, a medium pressure CO2-removed case and a high pressure CO2-removed case
Outline the advantages and risks of high pressure IGCC operation compared to medium pressure
Carry out an assessment to identify areas in which improvements to equipment are desirable and, if possible, propose solutions. Address expected problem areas namely the operation of lockhoppers at high pressure
Develop a device giving improved accuracy in the measurement of dense phase coal flow
This profile contains information on the project's:
Confirm the concept for a coal Gasification Enabling Module (GEM) that will produce syngas for existing natural gas fired combined cycle (NGCC) power plants at a price competitive with natural gas and that can reduce carbon emissions by 85% or more.
Advance the existing technical documentation for the concept to a more developed stage.
Develop more accurate costs and economics for the concept.
Further evaluate the economic potential of new adsorbents for the capture of CO2 and mercury.
Increase the understanding of the implications of firing coal derived gases as a retrofit fuel option for an existing NGCC plant.
The primary aim and objective of the work is to develop the technical and economic information that will assist existing or future owners and investors in the power industry to evaluate the advantages of utilising coal based syngas generated in a Gasification Enabling Module (GEM) to refuel existing NGCC plants which have the capability to remove 85% or more of the CO2 prior to
combustion. To achieve this objective, the study will evaluate GEMs located both adjacent and remote from existing NGCC plants and will evaluate the performance of the GEMs both before and after carbon capture. The results to date on these flow schemes are based on preliminary conceptual technical evaluations and preliminary cost estimates.
