Whakaahuatanga
Ko te tango waro hau māori (decarbonization) skid, he taputapu matua i roto i te purenga, te maimoatanga rānei o te hau māori. Ko te PSA he hangarau tango waro iti-pūngao e tutuki ai te mimiti me te tango CO2 mā te whakarerekē i te pēhanga whakahaere. Ko tēnei hangarau ka mimiti me te wehe i te CO2 mai i te hau māori i te pēhanga whakahaere o te 0.5~1MPa, kātahi ka uru ki te mimiti korehau hei whakaoti i te whakahoutanga o te adsorbent. No te adsorption tinana te tikanga PSA, ahakoa ki te whakataurite ki te adsorption matū, he iti tōna kaha adsorption me te iti o tōna whiriwhiringa; Heoi, he māmā te rere o te tukanga PSA, he roa te ora ratonga o te adsorbent, he ngāwari ki te whakahou, ā, he iti te whakapaunga pūngao. I te wa ano, he painga ano hoki penei i te aunoatanga teitei, ngā painga taiao pai, me te ngāwari whakahaere teitei. Ina koa ka mahi ki te hau whāngai pehanga teitei, kaore he take ki te pēhanga ano. Ka taea te whakahaere i te tikanga PSA i te pāmahana rūma me te kore e hiahiatia te whakamahana me te whakamatao, ka penapena 1-2 ngā wā e pau ana te pūngao ki te whakataurite ki te tikanga TSA; Heoi anō, ki te whakaritea ki te tikanga TSA ōrite, he iti ake te horopeta mimiti e hiahiatia ana mō te tikanga PSA.
Kaua te nui o te hauhā waro i roto i te paerewa kounga hau māori e neke atu i te 3%. Ā, he tino kaha te waikura o te hauhā waro i roto i te wai i muri i te whakarewatanga o te maitai. Mena he rite te uara PH, ka teitei ake te ōwehenga waikawa o te hauhā waro, nō reira ka teitei ake te nui o te waikura o te hauhā waro i runga i te maitai.
Ko te pēhanga pupuhi pēhanga (PSA) he hangarau hou e whakamahia ana hei wehewehe i te ranunga hau i roto i te hangarau wehenga pēhanga. Ki te whakatauritea ki te tikanga mimiti matū tuku iho, he mea ātaahua te hangarau PSA mō te tango me te whakaora i te H2S me te CO2 mai i te hau māori, ā, kei te kaha te whakawhanake.
He ngāwari te whakahaere i ngā painga o te hangarau wehenga hau PSA, he iti te ngaronga pēhanga, he maroke te hau i te wā e tangohia ana te CO2, he iti te ira tomairangi o te hau me te wai parakore, ā, ka taea e ngā hua te whakatutuki i ngā whakaritenga o te kaweake hau. Ka taea te whakamahi i te PSA mō te kukū CO2 me te tango whanariki whiriwhiri i roto i te hau māori.
tūtohi rere
I raro i te pēhanga te mahi mimiti, ā, i raro i te pēhanga iti te mahi mimiti. Nā te poto o te huringa mimiti, ā, kāore e taea te memeha haere te wera mimiti i te wā tika, ka taea te whakamahi mō te mimiti. Nō reira, he iti noa te rerekētanga o te pāmahana o te moenga mimiti i puta mai i te wera mimiti me te wera mimiti, ka taea te kī he tukanga isothermal. Ko te mahi moenga mimiti kotahi te pumau, ahakoa he mimiti hurihuri pāmahana, he mimiti hurihuri pēhanga rānei, nā te mea me whakahou te mimiti, ka wāwāhi te mimiti. I roto i te ahumahi, e rua, neke atu rānei ngā moenga mimiti e whakamahia ana, kia mahi tauutuutu ai te mimiti me te whakahou o te moenga mimiti (i te huringa takitahi rānei), kia mau tonu ai te tukanga mimiti katoa.
Ngā āhuatanga mahi
Ko te whai huatanga o te paheketanga tango waro o te pēhanga pēhanga he 90%. Ka taea te wehe i te CO2 mā te whakarerekētanga pēhanga me te mimiti ā-tinana, me te kore he tauhohenga matū. Haunga te tango CO2, e whakamahia whānuitia ana te hangarau PSA i roto i te whakaora me te purenga o te H2, CH4, CO, CO2 me ētahi atu hau.
