Description

The Government of Canada aims to reach net-zero greenhouse gas emissions nationwide by 2050. To achieve this goal, a suite of different technologies is required to help different industrial sectors reduce their emissions. Pressurized chemical looping (PCL) combustion is being developed to facilitate decarbonization for small and medium-sized industrial emitters (<~115,000 t CO2/year). The PCLC process produces a pressurized CO2 product, allows for recovery of latent heat from the flue gas and has a compact footprint. These factors make it an attractive option for smaller emitters in the North American market looking for CO2 capture solutions to replace aging gas-fired boilers and process heaters. The pressurized chemical looping research program at CanmetENERGY-Ottawa includes development and testing of a 600 kWth fluidized bed pilot plant, techno-economic evaluation for industrial applications, and investigation of process improvements to reduce operating costs and remove trace impurities from the CO2 product. The pressurized natural gas-fired pilot plant, developed in collaboration with Hatch Ltd, is currently under construction with testing planned to start in 2025. Initial test work will evaluate the US Department of Energy developed tri-metallic oxygen carrier and a copper-alumina oxygen carrier. Key performance metrics being analyzed include fuel conversion, oxygen utilization, heat exchange effectiveness, CO2 purity and capture efficiency, and oxygen carrier performance. This presentation includes an overview of the design, capabilities, and analysis approach for the pilot plant testing. Plans for future work, including pilot testing of turbochargers and development of intensified heat exchange reactors for impurity removal will also be discussed.
