    摘要: A gas separation device having a simple structure and reducing the cost incurred in gas separation. The gas separation device (100) includes an adsorption tower (110) having at least one part thereof exposed to an atmosphere at a higher or lower temperature than normal temperature, a mixed gas feed unit (120), an adsorbent (130) provided inside the adsorption tower to adsorb a matter contained in a mixed gas upon contact with the mixed gas in a prescribed pressure and temperature environment, and separate the matter from the mixed gas, a separated gas discharge unit (140) that discharges a separated gas from the adsorption tower, and an adsorbed gas discharge unit (150) that reduces the pressure inside the adsorption tower and discharges from the adsorption tower the adsorption gas which is adsorbed by the adsorption agent. Heat reserving elements (160) are arranged in the adsorption tower at positions upstream and downstream of the adsorption agent in the mixed gas supply direction respectively such that the mixed gas, separated gas, and adsorbed gas flow through the heat reserving elements.

    摘要: A multicapillary bundle for use in a gas chromatograph. Each of the capillaries in the bundle is formed using a coating solution containing a stationary phase and a solvent. The capillaries are coated with stationary phase by reducing pressure at a vacuum end of the capillary and creating a moving interface between the coating solution and a film of stationary phase deposited on each of the capillaries. The reducing pressure at the vacuum end of the capillary and the temperature of the capillary are controlled to maintain motion of the moving interface away from the vacuum end of the capillary. Maintained movement of the interface prevents recoating of the stationary phase. A heating wire and capillaries are embedded in a thermally conductive polymer to create a highly responsive method of heating the multicapillary column. An electronic control device controls the feedback temperature of the multicapillary column using the heating wire.

    摘要: This invention concerns a method for recovering carbon monoxide and carbon dioxide from Fischer-Tropsch off-gas by feeding Fischer-Tropsch off-gas through a column comprising an adsorbent bed, and discharging effluent, optionally rinsing the column and the adsorbent bed by feeding NG and discharging effluent until at least 60% of the carbon monoxide that was present in the bed is discharged, pressurizing the column and adsorbent bed with NG, rinsing the column and the adsorbent bed by feeding NG until at least 50% of the carbon dioxide present at the commencement of this rinsing step is discharged, rinsing the column and adsorbent bed by feeding a mixture of hydrogen and nitrogen, pressurizing the column and adsorbent bed by feeding a mixture of hydrogen and nitrogen. With this method a feed comprising at least 50 vol % carbon monoxide can be produced. Furthermore, methane and carbon dioxide at a high pressure can be recovered from the Fischer-Tropsch gas. This can be fed to a gasifier or a reformer. In a preferred embodiment a gas comprising at least 80 vol % hydrogen is produced as well.
