Whakaahuatanga
He taputapu matua te reti whakamaroke i te tātari ngota irahiko i roto i te purenga hau māori, i te whakatikatika rānei i te hau māori. He tioata aluminosilicate whakarewa kawakore te tātari ngota, he hanganga anga, he hanganga moroiti rite tonu. Ina haere te hau whāngai kei roto he wai iti i roto i te moenga tātari ngota irahiko i te pāmahana rūma, ka mimitihia te wai iti me te mercaptan, ā, ka whakaitihia te nui o te wai me te mercaptan i roto i te hau whāngai, ka tutuki ai te kaupapa o te whakamaroke me te tango i te whanariki. Ko te tukanga mimiti o te tātari ngota ka mahia i te pāmahana iti me te pēhanga teitei, ko te whakaora tango i te pāmahana teitei me te pēhanga iti. I raro i te mahi a te hau whakaora pāmahana teitei, ma me te pēhanga iti, ka tukuna e te adsorbent tātari ngota te adsorbate i roto i te micropore ki roto i te rere o te hau whakaora kia tae ra ano te nui o te adsorbate i roto i te adsorbent ki te taumata tino iti, ā, ka taea te mimiti i te wai me te mercaptan mai i te hau whāngai, ka tutuki ai te tukanga whakaora me te hangarua o te tātari ngota.
Ko te tikanga tātari ngota he momo tikanga whakamaroke hohonu, e whakamahia ana i roto i te tukanga wehenga hauhautanga pāmahana-iti, pērā i te whakaora hauhautanga hau māori (NGL) me te tukanga whakamaroke i roto i te hanga hau māori wai (LNG). Hei tāpiri, ka whakamahia hoki te whakamaroke tātari ngota i roto i te hanga hau māori kōpeke mō te wahie motuka.
Ko te whakamaroke i te tātari ngota e tika ana mō ēnei wā:
a. Ko te wāhi e hiahiatia ana kia iti iho i te -40 ℃ te pāmahana tomairangi o te hau māori.
b. He pai mō te whakahaere i te ira tomairangi hauwai o te hau maori pēhanga teitei.
c. Ka whakamaroketia te hau māori, ā, ka purea i te wā kotahi.
d. Ina maroke te hau māori kei roto te H2S, ā, ka rewa ki roto i te glycol, ka puta te hau whakaora.
e. Ina matewai te LPG me te NGL, me tango te iti o te sulfide (H2S, CO,COS, CS2, mercaptan) i te wā kotahi.
tūtohi rere
E whakamahia ana ngā momo ngongo moenga pumau mō te whakamaroke i te tātari ngota, nō reira me rua ngā momo ngongo o te waeine, tētahi kei te wāhanga whakamaroke i te whakauru, tētahi kei te wāhanga whakaora me te whakamatao. Mēnā he nui rawa te kaha o te waeine, ka taea hoki te whakarite i te tukanga maha-pou.
