Kafushane yethula isimiso sokusebenza kanye nezinzuzo zokukhiqizwa kwe-nitrogen ye-PSA
Indlela ye-PSA (Pressure Swing Adsorption) iwubuchwepheshe obusha bokukhiqiza i-nitrogen noma umoya-mpilo ngezinjongo zezimboni. Ingakwazi ukuhlinzeka ngokuphumelelayo nangokuqhubekayo igesi edingekayo futhi ikwazi ukulungisa ukuhlanzeka kwegesi ngezidingo ezithile. Kulesi sihloko, sizohlola ukuthi indlela ye-PSA isebenza kanjani kanye nezinzuzo zayo.
Isebenza kanjani i-PSA?
I-Compressor: Inqubo iqala nge-compressor efaka umoya kujeneretha ye-nitrogen ye-PSA. Lo moya uqukethe cishe u-78% we-nitrogen kanye no-21% we-oxygen.
I-Adsorption & Regeneration: Umoya ocindezelwe udlula ku-CMS, futhi ama-molecule amancane omoya-mpilo ayakhangiswa. Amangqamuzana e-nitrogen ayaqhubeka akhangisa nge-CMS ngenxa yobukhulu obuhlukahlukene (abakhudlwana) bamangqamuzana aze afinyelele endaweni yokugcwala. Ukuvala i-oksijini yomoya ecindezelekile engenayo izokhishwa futhi amathangi amabili axhunyiwe asebenze ndawonye ukuze akhiqize ukugeleza okuqhubekayo kwe-nitrogen.
Ukucushwa kwethangi elikabili: Isisefo se-Carbon molecular CMS sibekwe emathangeni amabili. Ithangi elilodwa liyakhanga ngenkathi elinye livuselela. Lokhu kulungiselelwa kunika amandla ukukhiqizwa kwegesi okuqhubekayo ngaphandle kwesikhathi sokuphumula.
Izinzuzo ze-PSA Method
1. Indlela ye-PSA yokukhiqiza amagesi inikeza izinzuzo eziningana, okwenza kube yisixazululo esithandwayo embonini. Nazi ezinye zezinzuzo:
2. Ukunikezwa kwegesi okuqhubekayo: Ngokucushwa kwamathangi amabili, ukukhiqizwa kwegesi okuqhubekayo kungafinyelelwa ukuze kuqinisekiswe umthombo wokuhlinzeka oqhubekayo nothembekile.
3. Ukuhlanzeka kwegesi okulungisekayo: Indlela ye-PSA ingalungisa ngokunembile ukuhlanzeka kwegesi ekhiqizwayo ukuze ihlangabezane nezidingo ezithile. Kwezinye izinhlelo zokusebenza, ukuhlanzeka okuphezulu kungafinyelelwa ngamanani okugeleza aphansi, okubalulekile kwezinye izinhlelo zokusebenza.
4. Ukuthuthukiswa kwezindleko zamandla: Ngamazinga aphezulu okugeleza, igesi ekhiqizwayo ingaba msulwa kodwa yanele ukuhlangabezana nezidingo eziningi zohlelo ngenkathi yonga izindleko zamandla. Lokhu kuvumela ukonga kanye nokwenza kahle kwenqubo yokukhiqiza.
5. Ukuphepha nokuthembeka: Indlela ye-PSA iphephile futhi ithembekile uma isetshenziswa. Inqubo ilawulwa futhi iqashwe ukuze kuncishiswe ubungozi bokungasebenzi kahle nezehlakalo ezingalindelekile.
6. Indlela ye-PSA iwubuchwepheshe bokukhiqiza igesi obusebenzayo nobuthembekile obaziwa ngokuthi i-pressure swing adsorption. Ihlinzeka ngokuqhubekayo i-nitrogen ehlangabezana nezidingo ezithile zokuhlanzeka. Indlela ye-PSA iphinde inikeze ukonga amandla kanye nezinzuzo zokuthuthukisa izindleko. Ngenxa yalezi zinzuzo, kuyisixazululo esivamile ezindaweni eziningi zezimboni.
