Ko te neke pai o te LNG ehara i te mea ko te kawe noa i te wai mai i te pūwāhi A ki te pūwāhi B. Ko te wero tūturu ko te whakahaere i te pikinga o te wera i te wā e whakawhiti ana. Ahakoa he iti noa te wera o te taiao ka taea te whakaputa hau kohua, te whakararuraru i te rere, me te whakaiti i te pai o te pūnaha katoa.

At HL Cryogenics, ka hangaia e mātou ngā pūnaha whakawhiti korehau e aro ana ki te pumau o te wera mō te wā roa, te iti o te turuturu wera, me te tuku wai kotahi-wāhanga pono. Ka whakakotahihia e ā mātou pūnahapaipa whakamahana korehau, ngongo ngāwaringā huihuinga, te hangarau korehau e mau tonu ana, me ngā taputapu whakahaere-wāhanga hei tautoko i te whakawhiti LNG pumau puta noa i ngā tono ahumahi me te moana.

He aha te Hiranga o te Whakamarumaru Korehau i roto i te Whakawhiti LNG

He tino pāngia ngā wai cryogenic pērā i te LNG e te wera e uru ana. I roto i ngā paipa whakamahana tikanga, ka piki haere ngā ngaronga wera i te wā e heke ana te mahi whakamahana. Ka taea e tēnei te arahi ki ngā tere kohua teitei ake, te kore pumau o te pehanga, me te koretake o te mahi.

Ngā paipa whakamahana korehauka whakatikahia tēnei mā te whakaiti i ngā momo whakawhiti wera matua e toru:

• Arataki totoka
• Te kawe hau
• Irahiko wera

Tō mātoupaipa whakamahana korehauā, ka whakamahia e ngā pūnaha ngongo ngāwari he hanganga pakitara-rua me te āputa porowhita teitei-korehau, e puritia ana i raro i te 1 × 10⁻⁵ mbar. I raro i ēnei āhuatanga, tata kore te kawe hau me te kawe hiko nā te mea ka tino onge ngā ngota hau e toe ana ki te whakawhiti wera.

Hei whakaiti i te whakawhiti wera hihi, ka tāutahia he whakamarumaru paparanga maha (MLI) huri noa i te paipa o roto. Ka whakaitihia e ēnei paparanga whakaata te mimiti wera hihi mai i te koti o waho.

Ko te hua he taumata mahi wera kei tua atu i te pahuka tikanga, i ngā paipa cryogenic rānei kua whakamahanatia ā-mīhini.

Ko te tikanga, ka hangaia e mātou te paipa tukatuka o roto me te koti o waho mai i te maitai kore waikura 304L, 316L rānei hei whakarite i te pakari o te kiripaka, te ātete ki te waikura, me te mahi whakarewa pono i raro i te huringa wera auau.

Pūnaha Papu Korehau Hihirimō te Mahi Roa

Ko tētahi raruraru noa o ngā pūnaha korehau pūmau tuku iho ko te memeha haere o te korehau i roto i te wā. Mā te puta o te hau mai i ngā mata o roto, ngā turuturu iti o te wai, me te huringa wera ka āta piki ake te pēhanga porowhita, ka whakaiti i te whai huatanga o te whakamarumaru.

Hei whakatika i tēnei,HL Cryogenicsi whakawhanake i tētahiPūnaha Papu Korehau Hihirii hangaia mō te pumau o te korehau mō te wā roa.

Ka whakawātea tonu, ka whakawātea rānei te pūnaha i te wāhi porowhita mā te whakamahi i ngā papu panuku maroke, i ngā papu turbomolecular rānei. Ka wehea te wāhi korehau e te takirere kore-hoki i ngā wā tūtatari, ā, ka whakaratohia e ngā ine korehau whakauru te aroturukitanga wā-tūturu o te pēhanga porowhita.

Kua whakauruhia hoki ngā waeine adsorber hei hopu i te makuku me ngā warowaihā toenga i roto i te wāhi korehau.

Nā te mea e mau tonu ana te taumata korehau, ka noho pumau tonu te mahi whakamahana puta noa i te roanga o te ora mahi o te pūnaha, kaua e heke haere. I raro i ngā āhuatanga mahi noa, ka taea e te porowhita te noho tonu i roto i te awhe 10⁻⁶ mbar ahakoa i roto i ngā taiao wera me te makuku.

Ka whai wāhi tika tēnei ki:

• Ngā tere kohua LNG iti iho
• Te tuku wai pumau ake
• Te whakaiti i te auau tiaki
• Te whakapai ake i te whai huatanga o te huringa ora

Te Pupuri i te Rere LNG Kotahi-Wāhanga Pūmau

Ko te pumau o te whakawhiti LNG ehara i te mea e whakawhirinaki ana ki te mahi whakamahana anake, engari ki te whakahaere wāhanga whai hua anō hoki.

Tō mātoungā takirere whakamātao korehaukua hangaia hei pupuri i ngā pāmahana cryogenic puta noa i te raina whakawhiti me te whakaiti i te turuturu wera i ngā pūwāhi whakahaere nui. Mā ngā whirihoranga potae whānui ka pupuri i te takai kakau kia matara atu i te rohe makariri, ka āwhina ki te aukati i te hanganga hukapapa me te whakapai ake i te pono o te mahi.

Hei whakahaere i te hau mura e puta ana i te wā whakawhiti,ngā wehewehe wāhanga kua whakamahanatia ki te korehaukua tāutahia ki mua i ngā papu, i ngā pūnaha tango rānei. Ka tangohia e ēnei wehewehe te mamaoa mai i te awa wai i mua i te taenga atu ki ngā taputapu tairongo o raro.

Ko te hoahoa wehewehe ko:

• Te rere o te urunga whakarara mō te wehenga porowhita
• Ngā hanganga whakapūmau taumata ā-roto
• Te whakamarumaru korehau e tiakina ana

Ka āwhina tēnei ki te aukati i te pupuhi o te kohu, ā, ka tino whakaiti i te mōrearea o te pakaru o te papu.

Ngā Tāke Itimō ngā Pūnaha LNG me ngā Pūnaha Waea Iti

Mō ngā teihana LNG pūkoro, ngā pūnaha reti, ngā tono whakawhiti iti ake rānei, ko ā mātouTāke ItiKa whakaratohia e te raupapa he rokiroki ārai korehau kiato mai i te 100 ki te 3,000 rita.

E tautokona ana te oko o roto mā te whakamahi i ngā tautoko hanganga iti te kawe wera, ā, kua whakauruhia ki te hangarau tiaki korehau hohe. Ka taea e ēnei tāke te mahi hei arai rokiroki waenga i ngā waka tuku LNG me ngā pūnaha tohatoha o raro.

I raro i ngā āhuatanga mahi pūmau, ka taea te whakawhāiti i ngā reiti pēhanga-ake ki raro iho i te 0.1 pae ia hāora.

Te Mahi Whakawhiti LNG Noa

Tērā pea ka whakahaerehia he pūnaha whakawhiti LNG paerewa i hangaia e HL Cryogenics i roto i:

• Ngā pēhanga mahi mai i te 6 ki te 20 pae
• Ngā tere rere tae atu ki te 8 m/s
• Ngā uara turuturu wera he iti iho i te 0.25 W/m

Mā te whakauru i te pūmaupaipa whakamahana korehauMā ngā wāhanga ngongo ngāwari i ngā pūwāhi whānui, i ngā ringa uta honohono rānei, ka taea te whakapai ake i te whai huatanga whānui o te pūnaha.

I roto i te maha o ngā tono LNG, ka heke te tere kohua ki raro i te 0.05% mō ia 100 mita o te raina whakawhiti ia hāora, ā, ka āwhina i te whakapai ake i te pumau whakahaere me te mahi ōhanga.

Tō mātoungongo ngāwari kua whakamahanahiangā whakamahinga o ngā huihuinga:

• Ngā matua o roto o te maitai kore waikura 316L kua kōpikopiko
• Ngā hanganga whiri o waho kua whakapakaritia
• Hanganga porowhita korehau kua takaihia ki te MLI

Mā tēnei ka taea e te ngongo te pupuri i te pumau o te korehau i raro i ngā huringa piko me te whakaheke wera.

Tauira Kaupapa: Teihana LNG i Vietnam

HL Cryogenicsi tuku tata nei i tētahi pūnaha whakawhiti waiokore 350-mita te roa mō tētahi kaupapa tauranga LNG i Vietnam.

I hangaia te pūnaha hei whakawhiti i te 200 m³/h o te LNG mai i ngā tāke rokiroki ki te tauranga uta i te 10 pae, me te tutuki anō hoki i ngā herenga tino pakari mō te kohua.

Ko te whirihoranga whakamutunga i whakaurua:

• Paipa mārō kua whakamahanatia ki te korehaumō ngā wāhanga roa, tika
• Ngongo korehau ngāwarii ngā hononga tauranga honohono
• TakiruaNgā Pūnaha Papu Korehau Hihirite pupuri i te pēhanga annulus 5 × 10⁻⁶ mbar

I te wā o te whakatūnga, i tau te turuturu wera i inehia ki te 0.28 W/m pea. Ki te whakatauritea ki te paipa polyurethane-whakamātao o mua, i heke te kohua mā te 80%.

Te tāutanga o tētahiwehewehe wāhanga kua whakamahanahia ki te korehaui whakakorea hoki ngā raruraru pupuhi o te papu i puta ai ngā aukati mahi i mua.

I tēnei rā, ka whakahaerehia te pūnaha me te aroturuki tonu i te korehau me te huringa mahi papu kua whakaritea hei pupuri i te mahi pumau i roto i te taiao takutai wera me te makuku o Vietnam.

I hangaia mō te Whakatutukitanga ā-Ao

Kua hangaia ā mātou pūnaha whakawhiti cryogenic kia rite ki ngā paerewa matua o te ao, tae atu ki:

• ASME B31.3
