AB  - In recent years, the need to reduce energy consumption worldwide to move towards 
      sustainable development has led many of the conventional technologies used in the 
      industry to evolve or to be replaced by new alternatives. Oxygen is a compound 
      with diverse industrial and medical applications. For this reason, obtaining it 
      from air is one of the most interesting separations, traditionally performed by 
      cryogenic distillation and pressure swing adsorption, two techniques which are 
      very energetically expensive. In this sense, the implementation of membranes in a 
      hollow fiber configuration is presented as a much more efficient alternative to 
      carry out this separation. The aim of this work is to develop cost-effective 
      multilayer hollow fiber composite membranes made of Matrimid and 
      polydimethylsiloxane (PDMS) for the separation of oxygen and nitrogen from air. 
      PDMS is used as a cover layer but can also enhance the performance of the 
      membrane. In order to compare these two materials, three different configurations 
      are studied. First, integral asymmetric Matrimid hollow fiber membranes were 
      produced using the spinning method. Secondly, by using dip-coating method, a PDMS 
      dense selective layer was deposited on a self-made polyvinylidene fluoride (PVDF) 
      hollow fiber support. Finally, the performance of a dual-layer hollow fiber 
      membrane of Matrimid and PDMS was studied. Membrane morphology was characterized 
      by SEM and separation performance of the membranes was evaluated by mixed-gas 
      permeation experiments. The novelty presented in this work is the manufacture of 
      hollow fiber membranes and the way Matrimid is treated. This makes it possible to 
      develop much thinner dense layers than in the case of flat-sheet membranes, which 
      leads to higher permeance values. This is a key factor when implementing this 
      technology on an industrial scale. Membranes prepared in this work were compared 
      to the current state of the art, reporting quite good performance for the 
      dual-layer membrane, reaching O(2) permeance of 30.8 GPU and O(2)/N(2) 
      selectivity of 4.7, with a thickness of about 5-10 mum (counting both selective 
      layers). In addition, the effect of operating temperature on the membrane 
      permeances has been studied experimentally; we analyze its influence on the 
      selectivity of the separation process.
