OPTIMA aims to construct a vortex pilot line as a carbon capture breakthrough technology to overcome the challenges of the current processes and to support the Flemish industry innovation. The particularity of this technology is the use of a multi-stage vortex unit (MS-VU), which, thanks to its static geometry, does not require mechanical rotation and is, therefore, safely and easily scaled up. In addition, this pilot line, in a modular and skid-mounted manner, integrates CO2 absorption with solvent regeneration based on a patent-pending combination of two integrated vortex units: absorption and desorption. The compactness of the vortex unit (factor 10 to 100 compared to others) results in a significant CAPEX reduction of 70% and makes it easier to be transported and tested in industrial environments and for different applications.
