MATTRAN - Work Package 1

WORK PACKAGE 1: CO₂ STREAM SPECIFICATION

LEADER: DR J. GIBBINS

The CO₂ currently transported in pipelines is predominantly from natural sources and is transported for EOR purposes. There are no operational pipelines transporting CO₂ captured from power plant and the types of impurities that could be present are dependent on the capture technology, the capture process used and the composition of the fuel. The actual levels of impurities from any process will depend on the incentives for increasing the purity of the CO₂, which could be environmental, health and safety legislation, economics or operational constraints.

This work package will determine the likely CO₂ compositions delivered to pipelines for a range of plants in different operating regimes, including identifying characteristic levels of impurities where increasing CO₂ purity may only be achievable at excessive cost. This work will underpin other project activities including informing the requirements for the phase and dew point determination in WP2 of this proposal, the hydraulic modelling of WP3 and also the environments required for the materials testing in WPs4 and 5.

It is also likely to be of ongoing interest to regulators, industry and policy makers involved with CCS and particularly with CO₂ transport. Core activities will be undertaken jointly by Imperial College and Cranfield and will include a comprehensive literature survey and stakeholder/researcher dialogue. Extensive interaction with colleagues within the rest of the project is also expected, particularly where effective absolute limits in CO₂ composition requirements and capture/transport cost trade-offs are being identified.

In addition to the requirements of the project, the data generated in this task will also be used for techno-economic analysis of interactions between gas processing systems and transport pipelines (Imperial), an assessment of health and safety issues in relation to impurities (Imperial) and an assessment of engineering and operational issues related to impurities in streams of captured CO₂ (Cranfield).
