Chemical Technology

The Laboratory for Chemical Technology (LCT) integrates chemical science and engineering in its research on catalysis, polymerization, kinetics, reactor design and process design. LCT is part of the Department of Materials, Textiles and Chemical Engineering within the Faculty of Engineering and Architecture at Ghent University in Belgium and member of the Centre for Sustainable Chemistry (CSC) of Ghent University. LCT aims at research excellence and bottom-up innovation in the framework of technological, industrial, and societal challenges.

CO2 capture and solvent regeneration in gas-liquid vortex unit

Aim

The experimental study of the applicability of a gas-liquid vortex reactor (GLVR) for Carbon Dioxide (CO2) capture and in the consecutive solvent regeneration.

Context

In 2016 the Paris Agreement was ratified by the EU. It is a milestone in the EU response to the climate change. The absorption of CO2 is a challenge. Available CO2 separation technologies have high cost and technological limitations, restricting their general use in CO2 capture and Utilization (CCU). In the overall CAPTIN project (https://moonshotflanders.be/mot3-captin/) several types of new technologies for CO2 capture are studied.

Specifically, in the CAPTIN-1 project the use of a vortex reactor for gas-liquid flow was hydrodynamically confirmed. First data on gas-liquid mass transfer parameters of GLVR were gathered. In the CAPTIN-2 project, the GLVR technology will be further studied and optimized to demonstrate a cost-effective CO2 absorption/desorption process.

Program

The project aims at gathering a broad set of experimental data in a geometrically optimal GLVR.
- Study of the effect of GLVR geometry on hydrodynamics and CO2 absorption.
- Study of CO2 absorption results in the GLVR over a range of operating conditions.
- Study the effect of applied solvents.
- Study of the GLVR for solvent regeneration.
- Energetic study of solvent regeneration in a GLVR.
- Combining absorption and regeneration process in two GLVR.
