Capture and purification of CO₂ in exhaust gases

Technology selection, exhaust line integration and environmental metrics

Introduction

We model the capture and purification of CO in exhaust gases, adjusting the routes (distillation, absorption, membranes) to the composition, temperature, pressure and humidity of the flow. We implement and validate pilot prototypes and integrate separation with post-treatment systems. We evaluate performance and operational commitments, and apply LCA to prioritize technologies by environmental impact.

Research Areas

Capture prototypes: We design, implement and pilot-validate distillation separation systems with network of exchangers, compression/cooling and monitoring of composition and liquid fraction in tank. We test with synthetic gas and real exhaust to check performance and scalability.
Thermo-fluid dynamic modelling and alternative techniques: We developed digital twins based on mass/energy balances and state equations (Helmholtz) to predict properties, purity and liquid fraction. We sieve and compare routes for conventional exhaust (e.g. absorption and membranes), adjusted to current composition, T, p and humidity.
Integration with ATS and environmental assessment (LCA): We couple capture with the ATS to maximize overall efficiency and operational compatibility. We evaluate performance, consumption and trade-offs, and complement with LCA to prioritize technologies based on environmental impact.
