CO2 Solutions rotating packed bed pilot results

Jan 06 2017

The test program has demonstrated the potential to significantly reduce carbon capture capital costs.

CO2 Solutions has completed a performance assessment of rotating packed bed (RPB) equipment in the context of the further reduction of carbon capture costs, utilizing the Corporation’s proprietary enzymatic technology.
The programme, funded in part by a grant from the Natural Resources Canada ecoENERGY Innovation Initiative, consisted of an extended testing session at relevant scale at the University of North Dakota Energy & Environmental Research Center (EERC), as well as an analysis of equipment construction materials. The programme allowed for testing of both the CO2 absorption and stripping performance of RPB units from two suppliers.  
The Corporation is pleased with the testing results and can confirm that a significant potential capital cost reduction for carbon capture plants is achievable. This reduction is possible due to a combination of factors that enable CO2 Solutions’ enzyme-accelerated carbonate solvent, including choice of equipment, use of less costly materials, design of the high intensity contacting units, and simpler process configurations.
“Innovation is part of CO2 Solutions’ DNA, and the results of this latest testing programme show how we continue to reduce the costs of our carbon capture technology,” stated Evan Price, President and Chief Executive Officer of CO2 Solutions. “Based on these results, and in the context of governments imposing increasing penalties associated with emitting CO2, we believe we have an economically viable offering that will allow industry to meet carbon reduction targets while remaining competitive.”
RPB equipment, while offering similar performance to a packed tower configuration, has the advantage of a significantly reduced size, which enables technological and strategic opportunities in situations where footprint and/or space are limited. The utilization of high-intensity RPB equipment by the Corporation is made viable because of the performance of its proprietary enzymatic technology.
“Both our packed tower and RPB equipment approaches have now demonstrated stable and efficient capture capabilities meeting industrial requirements” stated Louis Fradette, Chief Technology Officer of CO2 Solutions. “The power of our proprietary enzymatic technology is that it significantly accelerates carbon capture. Additionally, where conventional technologies require high value steam to operate, our process using our carbonate solvent accelerated by our proprietary enzyme allows for the use of nil value low-grade heat to achieve operating results similar to conventional technologies but at much lower cost. With the high intensity aspect of the RPB equipment, we can now deliver systems that are significantly smaller than any other technology on the market.” 
CO2 Solutions now intends to continue testing of the RPB at larger scale for use in an industrial environment, within the context of the Quebec government funded carbon cycle project (Valorisation Carbone Québec). As announced in the Quebec budget in March 2016, the objective of the VCQ project is to demonstrate a complete industrial CO2 cycle, from capture to reuse into value-added products.
