Piloting of environmentally benign enzymatic solvent combined with an RPB absorber
ACCSESS will demonstrate at TRL7, on a 2tpd scale, post-combustion CO2 capture, using a non-amine, non-toxic enzyme enhanced solvent from Saipem (“CO2 solutions by Saipem”) combined with a novel and compact rotary packed bed (RPB) absorber from Prospin and Proceler.
Saipem’s aqueous potassium carbonate solvent, enhanced with the carbonic anhydrase enzyme (same enzyme as in human lungs) for rapid uptake and release of CO2, is regenerated at 70-80oC.
This opens opportunities for employing low-temperature industrial waste heat for CO2 capture purposes. This is expected to result in cost reductions, due to both to the low regeneration temperature and the compact RPB absorber.
This combined technology will be demonstrated in two different industrial environments: a pulp and paper mill in Sweden (Stora Enso), and a cement kiln in Poland (Heidelberg Materials). The cost-efficient approach for the piloting is to employ Hafslund Oslo Celsio’s transportable CO2 capture test rig, which will be slightly modified for the purpose, and to which the PSP RPB will be connected on a separate skid.
