uhlobo phakathi kwe-psa kunye ne-vpsa

PSA (Pressure Swing Adsorption) kunye neVPSA (Vacuum Pressure Swing Adsorption) zinezinto ezimbili zokuseparakha umoya okufana nokuthi zihlabelela izindlela eziningi zokusebenza kwiindawo ezidingekileyo. PSA isebenza ngokushintsha amandla esikhatsiwe noma futhi phakathi kumoya wendawo okanye lokuphuma ukuseparakha imifanekiso yomoya, uzokusebenza phakathi kwe-4-8 bar amandla. Umsebenzi uvumelela ngokuthi imifanekiso yomoya zingabuyiselwa ngamaxesha akhothani kumathathu. Ngaphandle, i-VPSA isebenza ngokushintsha amandla phakathi komoya wesikhephe phakathi kwe-0.3-1.0 bar phakathi komoya wendawo olukhethekileyo. Leli luhlangothi lesisekelo lokubuyisela umthombo wokuhlala kwesigaba, ukuze uhlobo lwemisebenzi lihlale kuhluke. Ukungazange kakhulu kulandelule kumthetho wezinga lemandla kunye nezinye izinto zokusetyenziswa zeenergy. Izinhlelo zesistimu sezPSA zizamele amandla engapheleleyo yokushintsha kodwa zisebenza ngeemehani ezisimpilisini, ngakho ke ezi VPSA zizamele amandla amahhula kodwa zithatha iipampe zesi-vacuum. Abanye abantu bazosebenzela kakhulu kwiinkomboni zokugcina, uphucelo lweoxyjeni kunye nepurifikhesi le-hydrogen, ngakho ke ezi VPSA zihlabelela kakhulu kwiindlela ezidingekayo ezinethunywa yabo yezinye izinto ngokusetyenziswa kweentsimbi.

Ukuphila kwezinto zombini ngePSA kunye neVPSA izimbongi ezinethuthukiseni ezidinga ukugcina izindlela ezidinga lokusebenza ngokulandelayo. Izinhlelo zakusebenza kwePSA zikhona ngaphambili ngokwesibonelo sokunquma okufanele, ukuze bazingeni kumthetho wokusetyenziswa kwesiqephu esizigciniswe ngamashumi. Bazo babe ngokubheke ukusebenza olungakho lomkhuhlane kwehlathi eliphakathi kunye nokuhlola kwezilondolozi ezikushaya. Ukusetshenziswa olunqanawe kwezinhlelo zakusebenza kwePSA uzoba ngaphansi komtheleli womsebenzi wokuqala kunye nokusebenza okuningi. Ngaphezulu, iVPSA zikhona ngokubhekeliseyo kweenergy lokuhlola umoya, zingabona ukuthi bazofuna amashumi angasihlanu-amasibhenzisi emfunyeneyo kunePSA ezintathu. Ukusebenza kwevacuum uzoba ungakhihla ukubuyiselwa kwesilondolozi sokubuyiselwa, ubheka ukuthi usizo lwesiphi sifunda ngokukhulu kunye nokusebenza olungakho lokuncedisiwe. I-VPSA zikhona ngokubhekeliseyo kuhlanganiswa lokuhlola izidingo eziveliwe kanye nokuba zingakho zingacost-effective ngokukhululeka lokusebenza olungakho. Amaphuzu amanani akusebenza kweVPSA azoba apha ahlola ukubuyiselwa kokunquma komphahla, ungenxa lokuba amakhompondo angazange abuyisele. Ngokushesha lokusebenza lokuhlola lokuhlola, i-VPSA inakwazi ukubuyela ngokungayiphi ingxenye yokusebenza, ukuba asibuyeleyo imali yokuthuthukisa. Ukukhetha phakathi kwePSA kunye neVPSA kuzoba kudinga ukuthi zingaba yini izidingo eziphawuliwe, amaxesha edluleyo kunye nokubalulekiswa kwezinsimbi, nangokuba i-VPSA ingakho ingavunyelwe ngokukhulu lokuhlola umoya wehlanu kunye nokuba i-PSA ingaqondiwe ngokukhulu lokuhlola hlathi elincinci kunye nokubuyiselwa kwehlathi.

Ukuphumelela kwezinhlobo zokusebenza nokusetyenziswa kweenergy

Ubungakanani obuchazene ngephakathi lokuphumelela kwezinhlobo zokusebenza phakathi kwe-PSA kunye ne-VPSA kulandelwa ngokwesibonelo sokuthi siyasebenza ngokubhekeleyo lwezimpawu. Izindlela ze-PSA zisebenza ngemiphawu okuhle, ngokugcineneyo amaphawathi aokunqumeni okanye nokuthi azifuna umnotho womncedisi wokuqaphepha ukuthi ukuqaphela imigasini yokusetyenziswa. Okokuba bafanele babe ngokulandelana nezinhlobo ezinethathe ngokuphambili. Izindlela ze-VPSA, ezisebenza ngokusebenzisa umthombo wokubhala, bazibuyekeza isenziyo sokuqaphepha kweenergy, ngokushesha kakhulu kuzenzukisweni lokuhlola amagasi atholakalayo, uzokubona ngokuthi akukho usetyenziswa kweenergy ngokwesikhatsi esikhoyo. Losenziyo sokuphumelela sithathelwa ngokushesha kakhulu kwiindawo ezilimi elihluhleneyo apho iicosts zokuqaphepha zingakumbi loluveshi olufanelekile lwezinhlobo zokusebenza.

Uhlobo lomgomo nokudibana kwezinhlobo

Ukuphahla kwezinto ezikhona ngokwesiphumo sokuthi okunye kunye neVPSA uhlobo lwezinhlelo zokuhlola izimpawu zezinhlangano zihlala kuhlu. Izinhlobo ze-VPSA zingabhedwayo amanani amakhulu ngenxa yalokho labe ngaphandle kokubuyiselwa kwesibhedlayo esidingayo phakathi komoya ongcinezeka ngokusebenzela umoya omnyama. Lokhu kuzifanelela ukuthi VPSA ifanele yindlela yokusebenza lokuthi amanani akhulu angenziwe, futhi ikhangelwe ukungavalelwe amanani ngalokho olukho lundekile ku-93%. Izinhlobo ze-PSA, ngokushesha besezingabhedwayo amanani amakhulu, zimabe kufanele zisethwe amaxesha angaphambili okanye uzimelo wemvelo ukuze zibuyele kumandla lokulula amanani a-VPSA. Umoya omnyama owaveliwe phakathi kwe-VPSA ubhekeka nokuthi ubhekeliswa kakhulu, ukuba kufanele ukusetha amaparamitha engenziwe ukuthi amandla amaphindwe ngendlela enjalo.

Ukulondoloza nokuthi Ukugcina

Izicwangciso nokuthuthukiswa kwezindlela zokusetyenziswa kwePSA ngeVPSA izihlelwa amaphatho angahlukene ngemibuzo yezilimi. Izisitayizi zePSA zinayo ingxenye elincinci nokusetshenziswa esingasiza, ukuba kube nenkqubo yokugcina okunamandla lokusebenza kwezindlela ezimbili nezindawo eziyinkulu zikhona imigomo. Zizoba kuqhubeka ngendlela yokubhala kumakhisho ongakho olungaphezu kweqhakamshane. Izisitayizi zeVPSA, ngokushesha zisetshenziswa ngokupheleleyo ngenkinga yakuvakansi, zihleliwe ngendlela yokubhala kunye nomphathisi wokuqala lokusebenza, ngokuhlukileyo kuhlelwa ngendlela yokubhala kunye nokusetshenziswa okungavulileyo kwezindlela ezinkulu, ngokwesiphiwo sokuthiwa i-okhijini. Ukusetshenziswa wesivakansi isetshenziswa ngokupheleleyo imiphumela yesethelo, ukuze kuhloyo kusetshenziswa kwezindawo ezinkulu. Ngakho ke, izisitayizi zeVPSA zinakuyintengiselo ukusetshenziswa kumthombo wefaciliti ezikhethekileyo ngevakuansi, ukuba akufanele ukutshintsha imali nokusetshenziswa.
