The principle of PSA separation of gas mixture is that the adsorption capacity of adsorbent for different gas components changes with the change of pressure. Ibigize umwanda muri gaze yinjira byakuweho na adsorpliption yo hejuru, kandi ibyo byanduye byashyizwemo kugabanuka k'umuvuduko n'ubushyuhe. The purpose of removing impurities and extracting pure components is achieved through pressure and temperature changes.
Umusaruro wa HSDA ukoresha JZ-512h MoleCure yaturimbuye adsorbent kugirango utandukanye hydrogène ikomeye kugirango itange hydrogen, yuzuye binyuze mumitutu yo guhindura uburiri bwa adsorption. Because hydrogen is very difficult to adsorb, other gases (which can be called impurities) are easy or easy to be adsorbed, so hydrogen rich gas will be produced when it is close to the inlet pressure of the treated gas. Umwanda urekurwa mugihe cyo gusuzumwa (kuvuka ubwa kabiri), kandi igitutu kigabanuka buhoro buhoro kumuvuduko wa pasitori
Umunara wa adsorption ubundi butwara inzira ya adsorption, igitutu. Kuringaniza no gusuzugura kugirango bigere ku musaruro uhoraho. Hydrogen ikomeye yinjira muri sisitemu munsi yigitutu runaka. Hydrogène ikomeye irenga umunara wa adsorption yuzuye adsorbent idasanzwe kuva hasi kugeza hejuru. Co / CH4 / N2 is retained on the surface of the adsorbent as a strong adsorption component, and H2 penetrates the bed as an adsorption component. Ibicuruzwa Hydrogène byakusanyijwe hejuru yumunara wa adsorption nuwasohotse hanze yumupaka. Iyo adsorbent muburiri bwuzuye hamwe na CO / CH4 / N2, hydrogène ikungahaye yahinduwe mubindi minara yubupfura. Muburyo bwa desorption, igitutu runaka cyibicuruzwa Hydrogène biracyasigaye mumunara wabitswe. This part of pure hydrogen is used to equalize and flush the other pressure equalizing towers just desorbed. This not only makes use of the remaining hydrogen in the adsorption tower, but also slows down the pressure rise speed in the adsorption tower, slows down the fatigue degree in the adsorption tower, and effectively achieves the purpose of hydrogen separation.
JZ-512h MoleCular yatunganijwe irashobora gukoreshwa kugirango ubone amazi yo hejuru hydrogène.
