Kuyerekeza ndi kusankha njira zamakono
The ndondomeko ya liquefaction gasi monga pretreatment (kuyeretsa) yaiwisi gasi, liquefaction (kapena LNG liquefaction chomera), refrigerant kufalitsidwa psinjika, kusungira katundu, Kutsegula ndi dongosolo wothandiza, etc. ndondomeko yaikulu zikuphatikizapo kuyeretsa yaiwisi mpweya ndi liquefaction wa oyeretsedwa mpweya. .
Kusankha njira yoyeretsera gasi
Monga gasi yaiwisi, gasi lachilengedwe liyenera kuyeretsedwa bwino liquefaction.Ndiko kuchotsa mpweya wa asidi, madzi ndi zonyansa mu gasi wa chakudya, monga H2S, CO2, H2O, Hg ndi ma hydrocarbons onunkhira, kuti apewe kutsekereza ndi dzimbiri. zida ndi mapaipi chifukwa kuzizira pa kutentha otsika.Table 5.1-1 amatchula mfundo pretreatment ndi pazipita zili zosafunika mpweya chakudya LNG chomera.
Kuchuluka kovomerezeka kwamafuta amafuta a LNG
| Chidetso | Malire okhutira | Maziko |
| H2O | ＜1ppmV | A (amaloledwa kupitirira malire a solubility popanda kuchepetsa zokolola) |
| CO2 | 50 ~ 100ppmV | B (kusungunuka kwa malire) |
| H2S | ＜4ppmV | C (zofunikira zaukadaulo wazinthu) |
| Zonse za sulfure | 10-50mg/Nm3 | C |
| Hg | ＜0.01μg/Nm3 | A |
| Ma hydrocarbon onunkhira | ≤10ppmV | A kapena B |
| Total naphthenic hydrocarbon | ≤10ppmV | A kapena B |
Malingana ndi deta ya gasi wa chakudya, madzi omwe ali mu gasi wodyetsa amaposa muyezo ndipo ayenera kuyeretsedwa.
A) Kusankha njira ya deacidification
H2S ndi CO2 zomwe zili mu gasi wachilengedwe zimatchedwa gasi wa asidi. Kukhalapo kwawo kudzachititsa kuti chitsulo chiwonongeke komanso kuwononga chilengedwe.Kuonjezera apo, ngati CO2 ili yochuluka kwambiri, mtengo wa calorific wa gasi wachilengedwe udzachepetsedwa. za ndondomeko ndi khalidwe la mankhwala.
Pali njira yoyamwitsa zosungunulira, mayamwidwe amthupi, njira yochepetsera oxidation ndi njira ya molecular sieve adsorption pochotsa mpweya wa asidi ku gasi wachilengedwe. ndi kugwiritsa ntchito zosungunulira zamchere ngati zosungunulira. Zosungunulirazo zimakhudzidwa ndi zigawo za asidi (makamaka CO2) mu mpweya wa chakudya kupanga mankhwala. Madzi ochuluka omwe amamwa mpweya wa asidi amatha kuwola ndikutulutsa mpweya wa asidi pansi pa kutentha ndi kuchepetsa kupanikizika, kuti azindikire kusinthika ndi kugwiritsa ntchito zosungunulira.
Pankhani ya kugwiritsa ntchito mphamvu, kuchuluka kwa mankhwala, ndalama zogulira ndi ntchito, njira yamadzimadzi ya MDEA amine ndiyo njira yoyenera kwambiri, motero njira yamadzimadzi ya MDEA amine imasankhidwa kuti iwonongeke mu chiwembuchi.
B) Kusankha njira yochepetsera madzi m'thupi
Njira yowonongeka kwa gasi nthawi zambiri imaphatikizapo kuchepa kwa kutentha kwa thupi, kutsekemera kwa desiccant ndi kuyamwa kwa zosungunulira. Kuzizira kolekanitsa kumagwiritsidwa ntchito makamaka kupewa hydrate ya gasi wachilengedwe pamene kutentha kuli kochepa, koma kutentha kwake kovomerezeka kumakhala kochepa, komwe sikungathe kukwaniritsa zofunikira za liquefaction ya gasi; zosungunulira mayamwidwe zambiri zikuphatikizapo anaikira asidi (zambiri anaikira phosphoric asidi ndi zina zidulo organic), glycol (amakonda ntchito triethylene glycol), etc., koma njira zimenezi ndi otsika kuchepa madzi m`thupi kuya, amene sangagwiritsidwe ntchito cryogenic unit; njira zolimba za desiccant zowonongeka ndi njira ya silica gel, njira ya molecular sieve kapena kuphatikiza njira ziwirizi.
Kusungunuka kwa gasi wachilengedwe ndi kuchepa kwa madzi m'thupi kuyenera kutengera njira yolimba ya adsorption. Chifukwa sieve ya molekyulu imakhala ndi kusankhidwa kwamphamvu kwa adsorption, mawonekedwe apamwamba adsorption pansi pa nthunzi wochepa wamadzi kupanikizika pang'ono, ndipo amatha kuchotsa mpweya wotsalira wa asidi nthawi yomweyo, 4A molecular sieve imagwiritsidwa ntchito ngati dehydration adsorbent mu chiwembu ichi.
C) Kusankha njira yochotsera mercury
Pakali pano, pali makamaka mitundu iwiri ya njira zochotsera mercury: njira ya HGSIV molecular sieve adsorption ya kampani ya UOP ku United States ndi momwe zimachitikira pakati pa mercury ndi sulfure pogwiritsa ntchito mpweya wopangidwa ndi sulfure wopangidwa ndi sulfure kuti apange mercury sulfide. activated carbon. Zakale ndizokwera mtengo komanso zoyenera pamwambowu wokhala ndi mercury wambiri; yotsirizirayi ndi yotsika mtengo komanso yoyenera pamwambowu wokhala ndi mercury yotsika.
Kumbali imodzi, mtengo wa ntchito ya HGSIV molekyulu sieve ndi wokwera kwambiri; kumbali ina, mercury zomwe zili mu gasi wodyetsa wa unityi ndizochepa. Choncho, ntchito sulfure impregnated mpweya Mercury kuchotsa ndondomeko, kampani ali zinachitikira bwino.
