Hydrogen is being purified from a high pressure 5.00x103 lb-mols of syngas (H2+CO) via a membrane. The retentate is 80% CO, and the membrane has a separation power of 45. The entropy of the streams is known ssyngas=1.42 BTU/lb-mol- R, spermeate=2.40 BTU/lb-mol- R S Retent.4.44 BTU/lb-mol- R. The temperature of the surroundings is 70.0 F. Assume that heat exchange may be neglected. a) Find the change in entropy for the separation. b) Find the minimum work for the separation. c) Calculate efficiency.
