- Utilities: Cov kev siv hauv qab no yuav tsum muaj:
- Biogas
- Hluav taws xob
Purified feed gas yog cryogenically txias thiab condensed nyob rau hauv tshav kub exchanger los ua kua natural gas (LNG).
Liquefaction ntawm natural gas tshwm sim nyob rau hauv ib tug cryogenic mob. Txhawm rau kom tsis txhob muaj kev puas tsuaj thiab thaiv cov khoom siv hluav taws xob, cov kav dej thiab cov li qub, cov pa roj yuav tsum tau ntxuav ua ntej liquefaction kom tshem tawm cov dej noo, CO2, H2S, Hg, hnyav hydrocarbon, benzene, thiab lwm yam.
Cov Nature Gas rau CNG / LNG txheej txheem muaj ob peb kauj ruam
Kev kho ua ntej: Cov pa roj ntsha yog thawj zaug ua kom tshem tawm cov impurities xws li dej, carbon dioxide, thiab sulfur.
Lub hom phiaj tseem ceeb ntawm natural gas pretreatment yog:
(1) Tsis txhob tso cov dej khov thiab cov khoom siv hydrocarbon ntawm qhov kub thiab txias thiab cov khoom siv txhaws thiab cov kav dej, txo cov roj xa hluav taws xob ntawm cov kav dej.
(2) Txhim kho tus nqi calorific ntawm cov nkev thiab ua tau raws li cov qauv roj zoo.
(3) Ua kom muaj kev ua haujlwm ib txwm muaj ntawm cov roj liquefaction chav nyob hauv cov xwm txheej cryogenic.
(4) Tsis txhob corrosive impurities rau corrode pipelines thiab khoom siv.
Liquefaction: Cov roj uas tau kho ua ntej yog tom qab ntawd txias rau qhov kub thiab txias, feem ntau qis dua -162 ° C, thaum lub sijhawm nws condenses rau hauv cov kua.
Cia: Lub LNG khaws cia rau hauv cov tso tsheb hlau luam tshwj xeeb lossis cov thawv ntim khoom, qhov chaw uas nws khaws cia ntawm qhov kub thiab txias kom tswj tau nws cov kua hauv lub xeev.
Kev Thauj Mus Los: Lub LNG thauj mus rau hauv cov tsheb thauj khoom tshwj xeeb lossis cov thawv rau nws qhov chaw.
Ntawm nws qhov chaw, LNG tau rov ua dua, lossis hloov rov qab mus rau hauv lub xeev gaseous, siv rau hauv cua sov, tsim hluav taws xob, lossis lwm yam kev siv.
Kev siv LNG muaj ntau qhov zoo dua li cov pa roj ntsha hauv nws lub xeev gaseous. LNG siv qhov chaw tsawg dua li cov nkev, ua kom yooj yim rau khaws thiab thauj. Nws tseem muaj lub zog tseem ceeb dua, lub ntsiab lus uas muaj zog ntau tuaj yeem khaws cia hauv cov khoom lag luam me dua ntawm cov roj uas muaj ntuj. Qhov no ua rau nws muaj txiaj ntsig zoo rau kev muab cov pa roj rau cov chaw uas tsis txuas nrog cov kav dej, xws li cov chaw nyob deb lossis cov Islands tuaj. Tsis tas li ntawd, LNG tuaj yeem khaws cia rau lub sijhawm ntev, muab cov khoom siv hluav taws xob ruaj khov txawm tias lub sijhawm xav tau siab.
