Evaluation and analysis of the performance of dehydration units for CO₂ capture

  • 1 April 2014
  • Capture
  • Transport

The purpose of the study is to examine the characteristics of the various dehydration processes and the way they can be best integrated into the CCS system. Moisture in CO2 can lead to corrosion and hydrate formation. It is necessary to dehydrate CO2 streams prior to transporting the product in carbon steel pipelines. Several different types of CO2 capture processes exist. The type selected for use is dependent upon the basic type of combustion process in operation, e.g. coal or natural gas. The CO2 produced by the various combustion and associated capture processes is of different quality, containing different inerts and impurities, with varying compositions and conditions. The dehydration process can be significantly affected by these differences; it was therefore necessary to consider the different types of capture process separately within this study.

CO₂ Pipeline Infrastructure

  • 1 December 2013
  • Transport

The deliverables for this study consist of a reference manual, database, interactive web tool and webinar. The reference manual highlights key design, construction, operational and regulatory learnings. A database, containing more than 100 data elements, complements the reference manual

Technical Review

Development of a Global CO₂ Pipeline Infrastructure

  • 1 August 2010
  • Transport

Projections of the scale on which CCS needs to be deployed to meet targets for CO₂ emissions reductions indicate that a massive CO₂ pipeline infrastructure will be required. To date CCS systems have tended to be based on dedicated pipelines connecting source to sink although some studies of regional CO₂ pipeline infrastructure requirements have been carried out. The purpose of this study is to examine the wider issues including design, financing, economics and regional differences.

Upgraded calculator for CO₂ pipeline systems

  • 1 March 2009
  • Costs of CCUS
  • Transport

A contract to develop and upgrade the original Woodhill program and the network program was awarded to Gastec UK/AMEC who had already produced the new network design program. After obtaining the original code from Woodhill-Frontier options were examined and it was felt that as both programs were Excel-based it would be simplest to amalgamate them into one program using the original Woodhill interface where possible.The possibility of adding a graphical map-based interface for the distributed collection network was investigated as an additional option but although possible the necessary licence for commercial use was found to be too costly. It was on this basis that GastecUK/AMEC proceeded with the development of the upgraded calculator.

Distributed Collection of CO₂

  • 1 September 2007
  • Capture
  • Transport

This study examines the design issues and costs of collecting CO₂ captured from multiple distributed sources down to quantities of 5000 tpa. It includes a spreadsheet model for sizing pipelines in a branched collection network with multiple pressure levels. This model also estimates overall collection costs including those for compression using unit costs for construction in the UK.
