I te mea ka rerekē te rahinga hoko o ngā hua LNG me te āhua o te mākete, me urutau te putanga LNG ki ngā huringa o te mākete. Nō reira, he nui ngā whakaritenga e whakatakotoria ana mō te ngāwari o te kawenga whakaputa me te rokiroki LNG o ngā tipu LNG.
Te whakahaere i te kawenga whakaputa LNG
Te whakahaere i te compressor Mr
He pūwero tohanga te pūwero MR. Ka taea te whakarite tonu i tōna kawenga i waenga i te 50 ~ 100% mā te whakarite i te taputapu whakau i te takirere whakauru hau me te takirere whakahoki o te pūwero.
Te whakahaere kawenga o te pūnaha maimoatanga mua
Kaua te kawenga hoahoa o te waeine hau whakakore waikawa e iti iho i te 100%. I runga i te kaupapa o te whakahaere i te pēhanga, ka taea te whakarite tonu i te taputapu pūnaha maimoatanga-mua i roto i te awhe kawenga o te 50 ~ 110% me te tutuki i te paerewa o te maimoatanga-mua me te purenga.
Te whānuitanga whakahaere kawenga o te pouaka matao waikura
Kaua te kawenga hoahoa o te pouaka matao wai e iti iho i te 100%. Ina huri te kawenga o te taputapu mai i te 50% ki te 100%, ka taea e te whakawhiti wera pereti me ngā takirere i roto i te pouaka matao te mahi noa me te whakatutuki katoa i ngā tikanga mahi o te kawenga rerekē.
Hei whakarāpopototanga, ko te ngāwari o te whakahaere o te taputapu katoa he 50% ~ 100%. Ka taea e ngā kaiwhakamahi te whakarerekē i te kawenga o te taputapu i roto i tēnei awhe kia rite ki te āhua hoko o te hua hei whakapai ake i te ōhanga o te whakahaere.
Te whakarerekētanga o te kaha rokiroki o te tāke rokiroki LNG
E ai ki te putanga LNG, ko te rahinga o te tāke rokiroki e tukuna ana e mātou ko te putanga LNG o ngā rā tekau, ā, ka taea te whakamahi i te rahinga rokiroki o te tāke rokiroki hei ārai i ngā huringa hoko.
Te huringa o te hanganga hau whāngai
Ka pā mai ngā wero ki te whakarerekētanga o te hanganga o te hau whāngai i roto i te maimoatanga o mua me te whakawaiwai.
Te urupare a te pūnaha maimoatanga hau whāngai ki ngā huringa wāhanga
Te urupare tango waro
E ai ki te nui o te hauhā waro e wātea ana, ka whakamahia e mātou te tikanga amine MDEA hei tango i te waro me te whakanui ake i te hoahoa o te hauhā waro ki te 3%. He maha ngā wheako hangarau kua whakaatu ka taea e tēnei hoahoa te urutau ki te huringa o te nui o te hauhā waro me te tango i te hauhā waro ki te taumata 50ppm.
Te tango i te warowaihā taumaha
Ko ngā warowaihā taumaha i roto i te hau māori ko te nuinga o te neopentane, te benzene, ngā warowaihā kakara me ngā wāhanga i runga ake i te hexane e kino ana ki te tukanga cryogenic o te pouaka makariri. Ko te kaupapa tango e whakamahia ana e mātou ko te tikanga adsorption waro whakahohe + te tikanga condensation pāmahana-iti, he kaupapa inihua rua-taahiraa me te takirua. Tuatahi, ka mimitihia ngā warowaihā taumaha pēnei i te benzene me ngā warowaihā kakara mā te waro whakahohe i te pāmahana rūma, kātahi ka whakakōpikopikohia ngā wāhanga taumaha i runga ake i te propane i te – 65 ℃, e kore e taea anake te tango i ngā wāhanga taumaha i roto i te hau whāngai, engari ka wehea hoki ngā wāhanga taumaha kia whiwhi ai i ngā warowaihā whakaranu hei hua taha.
Te urupare matewai
Ko te nui o te wai i roto i te hau māori e whakawhirinaki ana ki te pāmahana me te pēhanga. Kāore e nui te pānga o te panonitanga o ētahi atu wāhanga o te hau whāngai ki te nui o te wai. He nui te whakaaetanga hoahoa whakamaroke wai hei whakatutuki i tēnei.
Te urupare a te pūnaha waimeha ki ngā huringa wāhanga
Mā te panonitanga o te hanganga o te hau whāngai ka huri te pihi pāmahana wai o te hau māori. Mā te whakarerekē tika i te ōwehenga o te hau whakamatao whakauru (MR), ka taea te whakarerekē i te hanganga o te hau whāngai ki tētahi whānuitanga nui.
