Abstrakt: In this study the enrichment of methane in ventilation air by pressure swing adsorption (PSA) and by membrane separation was investigated theoretically. In the case of the PSA process, which uses Takeda G2X7/12 activated carbon, the impact...

Abstract: The basic aim of this study was to analyze the possibility of using commercial membrane modules in the recovery of methane from ventilation air. Experimental investigations concerning the separation of gaseous mixture containing 0.3 vol.% of...

Abstract: The basic aim of this study was to analyze the possibility of using commercial membrane modules to the removal of CH4 from ventilation air methane (VAM). Experimental investigations concerning the per-meation of pure gases (CH4, N2) and mixture...

Abstract: The present study aims at demonstrating how important it is to include the substantial increase in CO2 heat capacity around the critical temperature in the modelling of relevant PSA separations. It is shown that this parameter may considerably...

Abstract: In the case of experimental investigations concerning methane enrichment in the air it is necessary to avoid a rise of CH4 concentration above 5 vol.% i.e. its lower explosive limit. In order to determine experimentally safe ranges of pressure...

Abstract: The preliminary studies of indirect aqueous carbonation process using fly ash from lignite fluidized bed combustion are presented. Leachate after the dissolution of waste of pH=13 contained 0.0535 mol•l-1 of Ca+2. The experimental research...

Abstract: Review of literature data concerning poly(ionic liquid) membranes for gas separation is presented. The influence of polymer structure (e.g. cross-linking) on diffusivity and solubility of CO2, N2, CH4 is dis-cussed. Performance of cross-linking...

Abstract: Experimental results are presented which concern the adsorption equilibria of gaseous mixtures containing carbon dioxide, nitrogen and oxygen over zeolite molecular sieves 13X Grace which may be used in the separation of CO2 from flue gases....

Abstract: The main aim of the study was to experimentally determine the impact of water vapor in the process of carbon dioxide separation from flue gases. The conducted research allowed us to determine the data required for the calculation of the process...

Abstract: Experimental results are presented of the adsorption equilibria of water vapour over zeolite molecular sieves 13X (Molsiv and Grace) which may be used in the separation of CO2 from flue gas streams. It is found that water vapour is the strongest...
