Title: Recovery and purification of light gases by pressure swing adsorption

Abstract

A cell model is presented for the description of the separation of two-component gas mixtures by pressure swing adsorption processes. Local equilibrium is assumed with linear, independent isotherms. The model is used to determine the light gas enrichment and recovery performance of a single-column recovery process and a two-column recovery and purification process. The results are discussed in general terms and with reference to the separation of helium and methane. 5 figures, 2 tables.

  • Pressure Swing Adsorption (PSA) tests were perform
  • This project demonstrated the feasibility of producing high purity hydrogen from a coal gasification product gas mixture by Pressure Swing Adsorption (PSA) using a commercial 5A zeolite as the adsorbent. The major advantage of PSA over conventional hydrogen upgrading processes is associated with lower overall production costs. This is mainly due to the integration of PSA into H/sub 2/ production plants as a single unit operation by replacing the low temperature carbon monoxide shift, carbon dioxide wash and methanation steps. In this way, hydrogen production costs are typically reduced from 7 to 40%. A single bed PSA process was designedmore » to simulate the various steps of commercial multibed PSA plants. A new and very important step, ''Vacuum Purge'', was also investigated. 45 refs., 38 figs., 50 tabs.« less
  • The U.S. Army Edgewood Research, Development and Engineering Center is investigating the pressure-wing adsorption (PSA) as a potential advanced technology approach for regenerable collective protection in military vehicles required to operate in chemical/biological warfare theaters. Experiments to test the filtration performance of a laboratory-scale PSA system have been performed by adding 1,1,2-trifluoro-1,2,2-trichloroethane (R113) to feed air-stream and monitoring the purge-and product-stream, R113 concentrations, as the challenge proceeds. In addition, in-bed probes have been utilized to monitor the R113 concentration at 5 cm intervals along the length of the PSA bed during each experiment. The data resulting from these experiments havemore » been used to derive PSA performance-prediction models that will assist in the design and validation of PSA-based collective protection systems for various military applications.« less
  • The work accomplished during the first six-month period of Phase II consisted of process laboratory experimentation and computer modeling of the process. Work on demonstration unit design and fabrication has awaited the results of these two tasks. Now that data are available from the laboratory phase, some of the design work can be initiated. The laboratory work has included equipment development, shakedown operations and actual process runs with the laboratory scale units. The computer modeling has been delayed by some logistical issues. Prof. Ruthven, project modeling consultant, moved from the University of New Brunswick to the University of Maine duringmore » the early stages of Phase II. He was still able to take delivery of Prof. Alpay`s gProm computer simulation package (from Imperial College in the UK) during that period, but was not able to make any runs with the system. The University of Maine`s Sun Workstations were not totally compatible with the gProm program. It has now been installed at the University of New Brunswick and Prof. Ruthven will be able to make simulation runs at that University. Results will-be available in the immediate future.« less
