Membrane technologies for hydrogen and carbon monoxide recovery

Sustainable industrial growth is based on the development of new industrial processes able to solve global important problems like greenhouse gas emissions, energy efficiency and toxic waste. The separation and valorization of industrial flue gases with complex composition allows approaching sustainability. In this thesis, a case of study is defined as the tail gas generated in the manufacturing of carbon black. Hydrogen and carbon monoxide are identified as major valuable components. It is envisaged that membrane technology will allow to obtain H2 enriched permeate stream when polymeric membranes are used and CO can be obtained as permeate gas stream when facilitated transport - supported liquid membranes are used.
