CO2 Product for Power Capture in the Identify stage
- Undertake a high-level analysis of the impacts of the CO2 specification on both upstream and downstream processing options including indicative costs, risks and opportunities
- Identify a range of options that can be furthre evaluated in the next pahse.
- Identify the requirements and or opportunities for any further onsite or offsite treatment of the flue gas stream prior to capture or further processing of the CO2 product stream prior to transportation.
- The analysis should consider the opportunities for re-use of captured CO2 in local industries (such as enhanced oil / hydrocarbon recovery, fertiliser production, algae cultivation, chemical processing).
High-level analysis report which identifies a preferred range of CO2 compositions for various capture, dehydration, and compression technology options and the impact on the pre-treatment requirements on the inlet flue gas stream as well as subsequent transport and storage including:
- Typical flue gas composition from power station at ID fan outlet (inlet to stack)
- Expected resultant CO2 product specification from various capture, dehydration, and compression technology options
- Preferred flue gas stream inlet requirements for each capture technology option under consideration
- Preferred CO2 compositions for transport and storage options.
- Overview of limitations and impacts of the other pollutants such as dust, SOx and NOx,H2S, NH3
- Identification of any incremental treatment opportunities for either the flue gas or the CO2 product streams.
- High level assessment of re-use opportunities and how these would impact on the CO2 specification as well as upstream treatment or processing requirements.
Specific tasks include the following:
- Identify flue gas composition that could enter the capture process. The composition should highlight any substances which could adversely impact the performance of the capture plant
- Identify if any further treatment of the flue gas could be required prior to entering the capture plant, and identify pre-treatment options
- Identify the likely composition of the CO2 product stream from the various capture plant technology options
- Identify potential CO2 reuse options in the local area and likely CO2 specification requirements
- Identify any potential impacts or limitations of the resultant CO2 product stream on the downstream elements of transportation and storage or reuse
- Identify if any further treatment of the CO2 product stream could be required and identify treatment options
