Carbon capture membrane module

Figure 2.2 Schematic representation and list of variables for a single stage membrane module for post-combustion carbon capture.

In particular, the project is associated with a 25 tonnes per day COj capture plant, in which the flue gas is at atmospheric pressure and, apart from CO2 (about 11-12%), contains also other gases such as N2, O2, H2O, SO and NOj as well as particulate matter. For post-combustion CO2 capture, the project considers both the existing commercial separation techniques (solvent absorption with amino acid and potassium carbonate solvents) and also novel capture options, such as membrane and adsorption. With respect to the membranes, the programme includes the evaluation of the performance of module configurations under real flue gas conditions, and with respect to the membrane plant, two process options are available ...
