FREMGANGSMAADE OG APPARAT TIL SEPARERING AF EN GASBLANDING VED ADSORPTION |
摘要 |
<p>Process comprising: a) isobaric concurrent production (fp1 - fp2); b) equilibration between the said adsorber under partial vacuum and another countercurrent adsorber under recompression (fC1 - N4); c) a partial countercurrent evacuation towards a storage vessel (fR); d) a final countercurrent decompression (fa); e) countercurrent sweeping with gas of the storage vessel (fb); f) a partial countercurrent recompression by at least one equilibration (f'e); g) a final countercurrent recompression (f'd1 - f'd2); according to which process the sum of the durations of the operations according to c) and d) is smaller than the said dephasing and the sum of the durations of the operations according to c), d) and e) is smaller than twice the said dephasing; h) at least two adsorbers are simultaneously on isobaric production, characterised by: i) the number of adsorbers is at least equal to four and smaller than 3 + x + y, x and y being the number of adsorbers on production and y the number of equilibrations; j) the evacuation is introduced into the storage; k) each equilibration is "direct". …<IMAGE>… </p> |
