Vol 1 Chapter 37: Chemical Looping Combustion of Refinery Fuel Gas with CO₂ Capture

Jean-Xavier Morin and Corinne Be´al

Abstract: Chemical looping combustion (CLC) is a new combustion technology with inherent separation of CO₂. Metal oxides are circulating between two fluid bed reactors: a fuel reactor for fuel oxidation and an air reactor for metal oxides oxidation by contact with air. The combustion products CO₂ and H₂O are obtained in a stream separate from oxygen depleted air stream. Alstom Power Boilers has developed a design concept for a large-scale Chemical Looping Combustion boiler (200 MWth refinery gas in Grangemouth) using modified circulating fluidized bed (CFB) technology with fluid bed heat exchangers. No hard point appears in terms of technology except metal oxide durability needs to be confirmed. Preliminary economics suggest that for a 200 MWth CLC gas fired CFB boiler CO₂ mitigation costs could be among the lowest for the technologies so far screened by the CCP. Detailed economics are currently being developed for alignment with other technology option costs reported by the CCP common economic modeling team (CEM) during the course of the 2003/2004 development project. CLC technology for refinery and natural gas combustion using CFB boilers might appear as a leading technology in term of competitiveness for CO₂ removal and quick access to the market after a long-term prototype operation and a demonstration unit operation.

Vol 1 Chapter 38: Capture and Separation Technology Gaps and Priority Research Needs

Helen R. Kerr

Abstract: This final chapter summarizes the major conclusions and results of the CCP’s capture and separation technology development projects. It provides a look forward to Phase II of the CCP and future research needs. Separation technology challenges include:

• A fundamentally different approach to post-combustion capture. The CCP saw some potential for novel integrated approaches for separation with advanced solvents.
• Pre-combustion decarbonization to make hydrogen at very large scale as a precursor to a hydrogen-based combustion system. A systems analysis and comprehensive approach to the major components of a hydrogen fuel system are needed.
• Oxygen-fired combustion. Combustion in either oxygen-enriched air or pure oxygen offers the advantage of reduced NOx and SOx emissions while producing a highly concentrated CO₂ stream for sequestration. Oxygen production is a major need and challenge – at the needed scale and costs. Chemical looping combustion that combines oxygen production with combustion may have great promise. It needs comprehensive study to determine its future potential. Public policy, incentives and regulatory activities by the various governments will be a substantial challenge for those attempting to sequester CO₂. Worldwide governmental actions must be monitored and accounted for in future technical developments.
