PhD M/F : Hollow fiber membrane contactors for CO2 capture at low pressure in physical solvents, theoretical and experimental study

-The Laboratoire Réactions et Génie des Procédés (LRGP) is a joint research unit of the CNRS and the Université de Lorraine. It is located in Nancy, France's second-largest student city. It is mainly located in the city center, on the premises of the Ecole Nationale Supérieure des Industries Chimiques de Nancy (ENSIC). The research laboratory is a leading chemical and process engineering laboratory in France and worldwide (18 CNRS researchers, 82 teacher-researchers, 43 technical and administrative staff and 180 non-permanent staff: contract researchers, PhD students, post-docs and master's students).

Capturing the CO2 emitted by human activity is one of the solutions needed to limit climate change. The aim of this thesis is to develop new CO2 capture processes using Hollow Fiber Membrane Contactors (HFMC). We are particularly interested in capture processes using physical solvents to treat low-pressure effluent gases, post-combustion fumes and effluents from methanation process plants. Modeling flows and transfers within HFMCs will enable us to identify optimal geometry and operating conditions for the absorption and regeneration steps and for different solvents. To validate the theoretical study, an exhaustive experimental study will be carried out in a pilot plant currently being set up. The technological change aims to achieve capture with a significant reduction in energy cost, compared with conventional technology using reactive absorption in a packed column.
