Ngā Kaupapa Taketake o te Hanga Methane Waro me te Wai i Whakaputaina
He Tirohanga Whānui mō te Tangohanga Methane i roto i te Waro
Ko te tangohanga methane waro (CBM) e aro ana ki te hau methane e piri ana ki ngā mata o roto o ngā tauranga waro. Kāore i rite ki te hau kore utu i roto i ngā puna waro tuku iho, ka puritia te CBM i roto i te anga waro mā te mimiti ā-tinana me te mimiti matū. Ka tīmata te whakaputanga mā te whakaiti i te pēhanga wai-pūmau, e tutukihia ana mā te pupuhi i te wai hanganga—e mōhiotia ana ko te whakamaroke. Mā te whakaiti i te pēhanga ka taurite anō te taurite mimiti, ka akiaki i te mimiti methane mai i ngā mata waro.
Ka haere tonu te mimiti i roto i ngā wāhanga: ka heke ngā ngota methane mai i ngā mata waro o roto mā roto i ngā whatunga o ngā pūwero moroiti me ngā pūwero nui, ngā pakaru, me ngā kōhao tūturu. Ka rongoa e te anga waro te methane nā te nui o te horahanga o roto me te iti o te urunga. Ka haere tonu te tangohanga i te mea ka whakaitihia te pēhanga e te tangohanga wai, ka āta whakanuia te tukunga methane.
E whakaatu ana ngā taunakitanga o te mara, ko te hua o te methane e whakawhirinaki ana ki ētahi āhuatanga: te nui o te hau i roto i te whakatakotoranga tuatahi, te taumata o te waro (he maha ngā wā ka nui ake te hau e puta mai i ngā whakatakotoranga iti-bituminous me te bituminous), te whanaketanga o te uruhanga, me te hanganga o te waro. Ka taea e ngā rangahau whaihanga taiwhanga te wehewehe i ngā takoha mai i ngā puna methane kore utu me ngā puna methane kua mimitihia, hei āwhina i te whakahaere i ngā puna wai. E whakaatu ana te whakaahua nanopore matatau i te rerekētanga o ngā kaha here hau me te kaha mimiti puta noa i ngā taumata waro rerekē.
E hopukina ana e ngā tauira rua-porosity hou ngā ara hekenga hau: ka neke te methane mai i te waro moroiti ki roto i ngā pakaru e hono tahi ana, e mahi ana hei awa rere tuatahi ki ngā puna whakaputa. E whakaatu ana te whakatauira wai-mīhini ko te taumahatanga i puta mai i te mimiti—te pupuhi, te mimiti rānei i puta mai i te mimiti, te mimiti rānei—ka pā tika ki te uruhanga, ka pā ki ngā tere tango.
Ehara i te mea ka taea anake te mimiti hau mā te tango wai, engari ka puta hoki ngā huringa pēhanga capillary, ka whakarerekē i ngā tikanga rere hau. Ko te taiao maha-wāhanga uaua (wai, methane, i ētahi wā CO₂) e hiahia ana ki te whakahaere tika i te wai CBM kua whakaputaina pai, nā te mea ka taea e te matū wai tonu te whakatere, te whakaroa rānei i te tukunga methane i runga i te ihirangi ionic me te organic. Ko te horapa i roto i te matrix waro e whakahaere ana i ngā mahi whakawhāiti tere, e neke ana mai i te mimiti mata ki ngā tikanga horapa ngota i roto i ngā hononga uruhanga tino iti.
