Abstract: A zero solvent emission process is proposed using a membrane device and an ionic liquid as a solvent; integrating a non-dispersive absorption-desorption process, gas compression, and transport to sequestration area analysis. The study is based on a model of a hollow fibre module formulated with a system of partial differential equations in axial and radial directions, depending of the Graetz (Gz), solvent selection (H) and Sherwood (Sh) numbers. Numerical absorption results showing carbon dioxide (CO2) recovery costs are presented, comparing them with those obtained in an integrated conventional process where Monoethanolamine (MEA) is applied as absorbent liquid.
