CO2 Product for Power Capture in the Evaluate stage
Undertake a pre-feasibility analysis of the impact of the CO2 composition in relation to the selection of capture plant's dehydration and compression equipment and downstream transport and storage elements with respect to design, cost and project implementation. This activity also evaluates reuse opportunities for captured CO2.
Pre-feasibility analysis report outlining the CO2 composition from the selected capture plant and the impact on the transport and storage, including options considered and clear reasons why preferred design configuration was selected. The report should include:
- Complete flue gas analysis and stream conditions upstream and downstream of the capture plant
- HSE impacts of potential release and/ or venting
- Product and waste generation quantities and characteristics
- Waste handling philosophy
- Additional treatment of waste and waste handling
- Description of options assessed including cost, schedule and risk impacts to both upstream and downstream systems including various dehydration levels, compression configurations, transportation system operating conditions (supercritical or sub-critical pipelines) materials of consruction and degrees of residual contaminants.
- Sufficient engineering development of selected CO2 composition to support a prefeasibility level cost, schedule and risk surety
- CO2 reuse evaluation study to consider off-take conditions, quantities, and CO2 specification requirements for any CO2 re-use opportunities. The study should evaluate likely additional CAPEX requirements for additional processing and transportation to reuse location, and revenue from on-sale of CO2; this information should be included in the financial discounted cash-flow model
Specific tasks include the following for each option:
- Sufficient heat and mass balances to assess the flue gas composition including the minimum, average, maximum quantities during start-up normal and upset condiitons and likely durations that will enter and leave the capture process. The assessment should include any substances which could adversely impact the performance of the capture plant and subsequent transport and storage.
- Evaluate the impacts of the CO2 product specification on the upstream and downstream dehydration and compression plant, transportation and storage systems design, cost,schedule and project implementation and operational risks
- Carry out a cost benefit review of further treatment of the CO2 product stream and the associated impact on the downstream equipment
- Evaluate the potential operational and maintenance issues associated with the CO2 composition from the selected capture plant
- Evaluate the potential risks and safety hazards associated with the CO2 composition from the selected capture plant
- Evaluate the quantity of products (waste and other) that are likely to be generated and provide estimate of quantities
- Select preferred CO2 composition and dehydration and compression configuration
- Develop preferred option including sufficient engineering to provide a +/-25% cost estimate and risk mitigation to support a decision to move the study into Definition
