Kua oti pai i a mātou te whakaputa me te tuku i te 300Nm3/h o te tipu whakaputa hauwai hau methane whai rawa kua tohatohahia e Sinopec. Kei te hiahia ahau ki te tuku i tētahi kupu whakataki poto ki te tukanga whakaputa hauwai mai i te hau māori.
Nā te kaha haere o te whakamahinga pūngao, kua noho ko te kimi pūngao hou hei mahi nui. Hei pūngao tino kaha, he whānui ngā pūtake o te hauwai, tata kore he parahanga, he nui te whai huatanga o te hurihanga, ā, he whānui ngā tono. Ka taea e te whakaputa hauwai mai i te hau māori te whakaiti i te raruraru pūngao o Haina ki tētahi taumata, me te whakatairanga anō i te panonitanga o te hanganga whakamahinga pūngao o Haina.
Ka arotahi tēnei pepa ki te mātāpono o te hanga hauwai mai i te hau māori, te tukanga me te hangarau o te hanga hauwai mai i te hau māori, te whakarōpūtanga o te hangarau hanga hauwai mai i te hau māori me te tatau utu o te hanga hauwai mai i te hau māori.
1 Te kaupapa me te tukanga o te whakaputa hauwai mai i te hau māori
1.1Te mātāpono o te hanga hauwai mai i te hau māori
Ko te kaupapa matua o te tukanga whakaputa hauwai hau māori ko te tukatuka i te hau māori i te tuatahi, kātahi ka huri i te methane me te mamaoa hei waro hauota me te hauwai i roto i te reformer, ā, ka huri i te waro hauota hei waro hauota me te hauwai i roto i te nekehanga pourewa i muri i te whakaora i te wera para. Ko te kaupapa o tēnei hangarau tukanga e whakatinanahia ana i runga i te hangarau hurihanga mamaoa hau māori. I roto i te nekehanga pourewa, ka whakahaerehia te pāmahana tauhohenga i te aroaro o te whakakorikori, ā, ka tauhohe te waro hauota i roto i te hau hurihanga ki te wai hei whakaputa hauwai me te waro hauota.
I raro i te pēhanga me te pāmahana e tika ana, ka pāngia ngā alkane i roto i te hau māori e te raupapa o ngā tauhohenga matū hei whakaputa i te hau hurihanga. I muri i te haerenga o te hau hurihanga mā te taputapu PAS e mau ana i ngā momo adsorbent i raro i te mana aunoa, ka mimitihia te hauota waro, te hauhā me ētahi atu poke e te pourewa adsorbent, ā, ka tukuna te hauwai ki te wāhanga kai hau hei mimiti i te adsorbent o ngā poke. I muri i te mimiti, ka taea te tuku i te hau tātari ki te oumu neke hei wahie, ā, ka taea hoki te hanga anō i te adsorbent.
Ko te tauira matua o te tauhohenga koia tēnei:
Ka tauhohe te hau māori me te wai i te 800 ~ 900 ℃, ā, ka puta he hauota waro me te hauwai mā te whakamahi i te whakakorikori nikara waikura.
Ko te tātai tauhohenga ko: CH4 + H2O → CO + H2-Q
Ka tauhohe te haukini waro me te wai i te 300-400 ℃ me te whakakōkī waikura whanariki hei whakaputa i te haukini waro me te hauwai.
Ko te tātai tauhohenga ko: CO + H2O → CO2 + H2 + Q
Hei tāpiritanga, ko ngā whakaritenga hangarau e tika ana mō te tukanga whakarite koia ēnei:
Ko te pēhanga he 1.5 ~ 2.5 MPa te tikanga, ā, ko te whakamahinga hau māori he 0.4 ~ 0.5 m3 / m3 hauwai; Wā mahi: > 8000h; Tauine ahumahi: 1000 m3 / H ~ 100000 m3 / h.
1.2 Te tukanga whakaputa hauwai hau māori
Ko te tukanga whakaputa hauwai o te hau māori e whai wāhi ana ki ngā tukanga e whā: te maimoatanga mua o te hau whāngai, te hurihanga o te mamaoa hau māori, te hurihanga o te hauota waro me te purenga hauwai.
Ko te taahiraa tuatahi ko te taahiraa maimoatanga-mua o ngā rauemi mata. Ko te maimoatanga-mua i konei e pā ana ki te tango i te whanariki o te hau mata. I roto i te mahi tuturu, ko te hau maori, te hau konutea molybdenum, te raupapa hauwai konutea, e whakamahia ana hei tango i te whanariki hei huri i te whanariki waro i roto i te hau maori hei whanariki kore-waro, kātahi ka tangohia. He nui te rere o te hau maori mata e tukatukahia ana i konei, nō reira ka taea te whakamahi i te puna hau maori me te pēhanga teitei, ka taea rānei te whakaaro ki te tawhiti nui i te wā e whiriwhiri ana i te pūhiko hau maori.
Ko te taahiraa tuarua ko te hurihanga o te hau māori ki te mamaoa. Ka whakamahia te whakakorikori nikara i roto i te reformer hei huri i ngā alkane i roto i te hau māori hei hau whāngai me ngā wāhanga matua o te hauota waro me te hauwai.
Kātahi ka hurihia te hauota waro hei tauhohe ki te mamaoa wai i te aroaro o te whakakorikori hei whakaputa i te hauwai me te hauota waro hei whiwhi i te hau huringa ko ngā wāhanga matua ko te hauwai me te hauota waro. E ai ki te pāmahana huringa rerekē, ka taea te wehewehe i te tukanga huringa o te hauota waro kia rua ngā momo: te huringa pāmahana waenga me te huringa pāmahana teitei. Ko te pāmahana huringa pāmahana teitei e tata ana ki te 360 ℃, ā, ko te tukanga huringa pāmahana waenga e tata ana ki te 320 ℃. Nā te whanaketanga o ngā ārai hangarau, kua whakamahia te tukanga e rua-wāhanga o te huringa pāmahana teitei me te huringa pāmahana iti o te hauota waro i ngā tau tata nei, ka taea ai te penapena rauemi. Heoi, mō te take kāore i te teitei te ihirangi hauota waro i roto i te hau huringa, ko te huringa pāmahana waenga anake ka taea te whakamahi.
Ko te taahiraa whakamutunga ko te purenga hauwai. Ko te pūnaha purenga hauwai e whakamahia whānuitia ana ko te pūnaha PAS, e mōhiotia ana ko te pūnaha purenga me te wehenga PSA. He iti te whakamahinga pūngao o tēnei pūnaha, he māmā te tukanga, ā, he teitei te parakore o te hanga hauwai. I te taumata teitei rawa, ka eke te parakore o te hauwai ki te 99.99%.
