Liquefied natural gas (LNG) o le kesi fa'alenatura, e tele lava le methane, lea ua fa'alili i lalo i le vai mo le fa'afaigofie ma le saogalemu o le teuina ma felauaiga. E mana'omia pe tusa ma le 1/600th le voluma o le kasa fa'alenatura i le tulaga kasa.
Matou te tu'uina atu La'au Liquefaction Gas Faanatura i micro (mini) ma la'ititi la'ititi. Ole malosi ole laau e aofia ai le 13 ile sili atu ile 200 Tone/aso ole gaosiga ole LNG (20,000 i le 300,000 Nm).3/d).
Fafaga kesi:
- ● Ua pa'ulia le kesi
- ● Kesi fa'atasi / mumu
- ● Biogas
- ● Paipa kesi
O le LNG liquefaction plant e aofia ai faiga e tolu: faiga fa'agaioiga, faiga fa'atonutonu meafaigaluega ma faiga fa'aoga. E tusa ai ma punaoa eseese o le ea, e mafai ona suia.
E tusa ai ma le tulaga moni o le kesi puna, matoufaʻaaogaina le faiga sili ona lelei ma le faiga sili ona taugofie e faʻafetaui ai manaʻoga eseese o tagata faʻatau.O meafaigaluega fa'apipi'i fa'ase'e e fa'afaigofie ai felauaiga ma fa'apipi'i.
1. Fa'agasologa faiga
O le kesi fafaga fa'alenatura e fa'aosoina pe a uma ona fa'amama, tu'u'ese'ese, fa'atonuga o le mamafa ma le mita, ona ulufale atu lea i le faiga fa'ameamea muamua. Ina ua uma ona aveese CO2, H2S ,Hg, H2 O ma hydrocarbons mamafa, e ulu atu i le pusa malulu liquefaction. Ona E cooled i totonu o le ipu vevela exchanger, denitrified ina ua uma liquefaction, ma le isi subcooled, throttled ma emo i le tane moli, ma mulimuli, o le vaega vai vavae e ulu atu i le tane teuina LNG oloa LNG.
Ole siata fa'asolo ole LNG Plant fa'apipi'i fa'ase'e e fa'apea:
Ole faiga ole cryogenic LNG Plant e aofia ai:
- ● Fafaga kasa filtration, tuueseeseina, tulafono faatonutonu mamafa ma le iunite mita;
- ● Fafaga kasa pressureurization iunite
- ● Vaega mo togafitiga (e aofia ai le deacidification, faʻamama ma le mamafa o le hydrocarbon aveese, mercury ma le pefu);
- ● MR fua fa'atatau ma le MR fa'apipi'i ta'amilosaga iunite;
- ● LNG liquefaction unit (e aofia ai le denitrification unit);
1.1 Vaega o faiga faiga
1.1.1 Fafaga kesi vaega muamua togafitiga
Ole auala ole fa'agasologa ole kesi fa'ameamea muamua e iai uiga nei:
- ● Deacidification ma MDEA fofo o loʻo i ai le aoga o le faʻafefeteina laʻititi, maualalo le corrosiveness ma itiiti amine gau.
- ● Molecular sieve adsorption e faʻaaogaina mo le loloto o le dehydration, ma o loʻo i ai pea le maualuga o le adsorption e oʻo lava i lalo ifo o le vai maualalo o le mamafa o le ausa.
- ● O le faʻaaogaina o le kaponi faʻamalosi i le sulfur-impregnated e aveese ai le mercury e taugofie i le tau. O le Mercury e tali atu i le sulfur i luga o le sulfur impregnated activated carbon e maua ai le mercury sulfide, lea e adsorbed i luga o le carbon activated e ausia ai le faʻamoemoe o le aveeseina o le mercury.
- ● elemene faamama sa'o e mafai ona faamama le sieve mole ma faagaoioia le pefu carbon i lalo 5μm.
1.1.2 Liquefaction ma le pusaaisa
O le auala filifilia o le liquefaction ma le pusaaisa iunite o le MRC (faafefiloi refrigerant) refrigeration taamilosaga, lea e maualalo le taumafaina malosi. O lenei metotia e sili ona maualalo le faʻaaogaina o le malosi i totonu o auala masani e faʻaogaina ai le pusaaisa, ma faʻatauva ai le tau o oloa i le maketi. Ole vaega ole fa'a'aisa e fa'atatau e tuto'atasi mai le vaega fa'apipi'i ta'amilo. I le taimi o le faʻagaioiga, o le vaega faʻatusatusa e toe faʻatumu ai le pusaaisa i le vaega faʻapipiʻi faʻasalalau, faʻamautu le tulaga galue mautu o le vaega faʻamalosi faʻasalalau; A maeʻa ona tapunia le iunite, e mafai e le vaega faʻatusatusa ona teuina le pusaaisa mai le vaega maualuga o le faʻapipiʻiina e aunoa ma le faʻaaogaina o le pusaaisa. O lenei mea e le gata e mafai ona faʻasaoina ai le pusaaisa, ae faʻapuupuu foi le isi taimi amata.
O valve uma i totonu o le pusa malulu o loʻo faʻapipiʻiina, ma e leai se fesoʻotaʻiga flange i totonu o le pusa malulu e faʻaitiitia ai le leakage points i totonu o le pusa malulu.
