Addition of a CO₂ capture system to an existing power station has some impact on water consumption. CO₂ capture systems require additional water for cooling and process make-up, which can be of concern, particularly in areas of water scarcity. During the past decade, a number of relevant studies have been published that estimate the increase in water use when a capture system is added to Pulverised Coal (PC), Natural Gas Combined Cycle (NGCC) and Integrated Gasifier Combined Cycle (IGCC) power production facility.

The report, authored by the Institute’s capture experts Guido Magneschi, Ron Munson and Tony Zhang, provides insights about how adding a CO₂ capture system to a power plant impacts the volume of water withdrawn and consumed. The results of this analysis serve to dispel myths about the use of water in CCS systems. Specifically, they challenge the misleading assertion that CCS systems will double water consumption, which is often reported in papers and articles.

On the contrary, analyses of available data indicate that for power plants using wet-recirculating cooling systems, the increase in actual water consumed varies from approximately 20 per cent to 60 per cent, depending on the capture technology. For once-through cooling systems the increase can be negligible, or even negative when water recovery options are implemented. Water use estimates cannot be generalised, and are very dependent on the power plant type, the CO₂ capture technology and the cooling system used.

The Global CCS Institute presents a feasibility study report on applying carbon capture and storage (CCS) to a steel plant in China. Toshiba was commissioned to conduct the study through its business partner Tongfang Environment in collaboration with Shougang Jingtang United Iron & Steel of China. The study examined the application of CCS onto the Caofeidian steel plant.

The report covers the concept of capturing CO₂ from a Chinese steel plant, transportation and potential storage in an oilfield for enhanced oil recovery (EOR).

The study suggests that carbon capture in Chinese steel plants is a cost effective means of reducing carbon emissions compared with similar plants around the world.

This report is authored by Toshiba for the Global CCS Institute. Tony Zhang, Institute Senior Adviser for Carbon Capture, Asia-Pacific also provides an overview of the report in a new Insight available on the Global CCS Institute website.

The following report presents an overview of the Callide Oxyfuel Project (Stage 1 - Oxyfuel Combustion and CO₂ Capture) and describes in detail key technical aspects of the plant, project milestones, and lessons learned.

The Callide A facility located near Biloela in central Queensland comprises of 2 x 330 t/day air separation units, a 30 MWe oxy-fuel boiler and a 75 t/day CO₂ capture plant. The plant was commissioned in 2012 and as of March 2013 had achieved nominally 5500 hours of industrial operation in oxy-combustion mode and 2500 hours of industrial of the CO₂ capture plant.

The project has been able to demonstrate CO₂ capture rates from the Oxyfuel flue gas stream to the CO₂ capture plant in excess of 85%, and producing a high quality CO₂ product suitable for geological storage. In addition, other benefits observed from the oxy-firing and CO₂ capture demonstration have included: (i) increased boiler combustion efficiency; (ii) greater than 50% reduction in stack NO_x mass emission rates; and (iii) almost complete removal of all toxic gaseous emissions including SO_x, NO_x, particulates and trace elements from the flue gas stream in the CO₂ capture plant.

openCCS is the handbook for deliverying CCS projects brought to you by the Global CCS Institute. It has been built to guide you through the key processes and steps needed to deliver each component of an integrated CCS project. It’s a platform for sharing methodologies, best practices and lessons learnt from experience.

The Power Capture Section of the openCCS handbook contains:

Concept Studies

• Identify potential of the new or expanded business
• Consider new-build or retrofit for capture
• Consider saline reservoir or EOR or other for storage/beneficial reuse
• Document general features of the project
• Estimate order of magnitude costs of the project (both capital (+/-30-35% accuracy) and operating (+/-15-20% accuracy))

Prefeasibility Studies

• Consider different capture technologies
• Consider different EPC contractors
• Consider different process, location and project configuration options
• Consider different capacities for the project
• Assess the likely technical and economic viability of the project
• Recommend the preferred option and size for final study
• Estimate costs of the project (both capital (+/-20-25% accuracy) and operating (+/-10-15% accuracy))

Feasibility Studies

• Undertake front end engineering design (FEED) studies, clearly recommending one processing, location and project configuration, and prevent the need to be materially varied after project commitment
• Estimate costs of the project (both capital (+/-10-15% accuracy) and operating (+/-5-10%; closer to 5% accuracy))
• Select construction contractor and delivery approach (i.e. EPC)
• Obtain all required regulatory approvals
• Provide the basis for making an investment decision, and make final investment decision for construction of capture facility

Project Execution

• Complete the design detail for building the carbon capture asset
• Build the organisation and systems to manage the carbon capture asset
• Build the carbon capture asset
  • On time
  • On budget
  • To scope and quality
• Commission the carbon capture asset to operating state

Asset Operation

• Ramp-up operation of the carbon capture asset to ascertain true performance
• Modify the carbon capture asset (as necessary) to achieve required performance
• Operate the carbon capture asset to achieve required performance over asset life
• Maintain the carbon capture asset to achieve required asset life
• Modify the carbon capture asset to comply with legislated regulatory changes
• Modify the carbon capture asset to realise identified opportunities

Asset Decommissioning

• Operation of asset (i.e. power plant with capture) ceased
• Modify the asset (as necessary) to achieve required decommissioned state
  • On time
  • On budget
  • To scope and quality
• Asset sites decommissioned and rehabilitated to required condition
• Establish organisation for post-closure stage (as necessary)
