A Sensitive Method Approach for Chromatographic Analysis of Gas Streams in Separation Processes Based on Columns Packed with an Adsorbent Material

Figure 7

Experimental (symbols) and simulated (lines) temporal profiles of total molar flow rate (), inlet composition (), and outlet composition () of the gas flowing through a column for the 3 cycles of a classical 4-column SMB (synchronous) operation: CH4/CO2 in N2, 309 K, and 4 bar. Every cycle, fresh feed, and eluent are added during and , respectively; extract is obtained at and raffinate is withdrawn at . The optimized feed flow rate is  mmol/min for a specific eluent consumption of and a switching interval of the cycle of [5].
