A pilot plant facility has been designed and built to trial potassium carbonate solvent technology for carbon capture under a range of conditions. The rig is capable of capturing 4 - 10 kg/hr of CO2 from 30 - 55 kg/hr of an air-CO2 mixture, with different packings. A series of trials have been completed with a range of solvent concentrations from 20 wt% to 30 wt% potassium carbonate. The experimental holdup, solvent loading and absorber temperatures have been matched with rate-based simulations in Aspen Plus® software. © 2013 The Author.
