HYBRID gas process separating unit

Cryogenic Air SeparationPressure Swing AdsorptionMembrane Separation TechnologiesIn 1895, Carl von Linde successfully liquefied air, attempting to obtain liquid carbon dioxide to be used in the brewing industry (Flavell-While, 2010). It was only later that separation methods were developed. This liquefaction process took three days. Separation methods have come a long way since then. Below is an early diagram of the liquefaction process.

  • Gas Separation by a Novel Hybrid Membrane/Pressure Swing

    Jul 17, 2007In the current work, the hybrid process is applied to H 2 /CH 4 separation over activated carbon by coupling the membrane to a five-step PSA cycle using scheme A. The membrane permeances are those commonly expected for a polysulfone membrane, with a typical selectivity of 35 for H 2 /CH 4 separation.Cited by: 26

  • A Hybrid Separation Process for the Recovery of Carbon

    Jan 01, 2013The hybrid process is a natural extension of the two-stage system. An important question is, however, what the sequence of the individual components of the whole arrangement should be. If we model the removal of CO2 as the separation of CO2/N2 mixtures [6], then both membrane and adsorptive systems will generate two gaseous streams.Cited by: 7

  • Membrane gas separation - Wikipedia

    Along the separation unit, the feed concentration decays with the diffusion across the membrane causing the concentration at the membrane to drop accordingly. As a result, the total permeant flow (q out) results from the integration of the diffusion flow across the membrane from the feed inlet (q in) to feed outlet (q out). A mass balance across a differential length of the separation unit is therefore:
