Kusankha njira yoyeretsera gasi wachilengedwe

Kuyerekeza ndi kusankha kwaukadaulo

Njira yothira mpweya wachilengedwe imaphatikizapo kuyeretsa mpweya wa chakudya (kuyeretsa), kuthira madzi, kupondereza mpweya wozizira, kusungira zinthu, kukweza katundu ndi njira zothandizira. Njira yaikulu yogwiritsira ntchito mafuta imaphatikizapo kuyeretsa mpweya wa chakudya ndi kuthira madzi wa mpweya woyeretsedwa.

Kusankha njira yoyeretsera gasi wachilengedwe

Mpweya wachilengedwe monga mpweya wodyetsa uyenera kuyeretsedwa bwino musanamwe madzi. Izi zikutanthauza kuti, chotsani mpweya wa asidi, madzi ndi zinyalala mu mpweya wodyetsa, monga H₂S, CO₂, H₂O, Hg ndi ma hydrocarbon onunkhira, kuti asazizire pa kutentha kochepa komanso kutsekereza ndi kuwononga zida ndi mapaipi.

A) Gome 1-1 limalemba miyezo yokonzekera mpweya wothira mafuta mu fakitale ya LNG komanso kuchuluka kwa zinthu zosafunika zomwe zilimo.

Gome 1-1 kuchuluka kwa mpweya woipa wa LNG womwe ungalowe m'malo mwake

Kuchokera ku deta ya mpweya wodyetsa, kuchuluka kwa kaboni dayokisaidi mu mpweya wodyetsa kumaposa muyezo ndipo kuyenera kuyeretsedwa.

Njira yamadzimadzi ya MDEA amine ndiyo njira yoyenera kwambiri pankhani ya kugwiritsa ntchito mphamvu, kuchuluka kwa chithandizo, ndalama zomwe zimagwiritsidwa ntchito komanso ndalama zogwirira ntchito. Chifukwa chake, njira yamadzimadzi ya MDEA amine imasankhidwa kuti ichotse asidi mu ndondomekoyi.

B) Kusankha njira yochepetsera madzi m'thupi

Kupezeka kwa madzi mu mpweya wachilengedwe nthawi zambiri kumabweretsa zotsatirapo zoopsa: m'mikhalidwe ina, madzi ndi mpweya wachilengedwe zimapanga madzi oundana kuti atseke payipi ndikukhudza njira yozizira yothira madzi; Kuphatikiza apo, kupezeka kwa madzi kungayambitsenso kugwiritsa ntchito mphamvu zosafunikira; Chifukwa cha kutentha kochepa kwa madzi achilengedwe komanso kupezeka kwa madzi, zidazo zidzazizidwa ndi kutsekedwa, kotero ziyenera kuuma.

Njira yochotsera madzi m'thupi pogwiritsa ntchito mpweya wachilengedwe Kawirikawiri imakhala ndi magulu atatu: kusowa madzi m'thupi kutentha kochepa, kulowetsedwa kwa desiccant yolimba ndi kuyamwa kwa zosungunulira. Kulekanitsa kuzizira kumagwiritsidwa ntchito makamaka popewa hydrate pamene kutentha kwa mpweya wachilengedwe kuli kotsika. Komabe, kutentha kochepa komwe kumalola kumakhala kochepa ndipo sikungakwaniritse zofunikira za liquefaction ya mpweya wachilengedwe; Kuyamwa kwa zosungunulira nthawi zambiri kumaphatikizapo asidi wokhuthala (nthawi zambiri organic acid monga phosphoric acid wokhuthala), glycol (triethylene glycol yomwe imagwiritsidwa ntchito nthawi zambiri), ndi zina zotero, koma njira izi zimakhala ndi kuya kochepa kwa madzi m'thupi ndipo sizingagwiritsidwe ntchito m'mayunitsi a cryogenic; Njira zodziwika bwino za desiccant yolimba ndi njira ya silica gel, njira yosefera ya molekyulu kapena kuphatikiza njira ziwirizi.

Njira yothira madzi yolimba iyenera kutsatiridwa kusungunuka kwa mpweya wachilengedwePopeza sieve ya molekyulu ili ndi ubwino wosankha bwino madzi, mphamvu zambiri zothira madzi pansi pa nthunzi ya madzi yochepa komanso kuchotsa mpweya wotsalira wa asidi, sieve ya molekyulu ya 4A imagwiritsidwa ntchito ngati adsorbent yothira madzi m'malingaliro awa.

C) Kusankha njira yochotsera mercury

Pakadali pano, pali njira ziwiri zazikulu zochotsera mercury: njira ya hgsiv molecular sieve adsorption ya kampani ya UOP ku United States ndi sulfure yomwe imayikidwa mu activated carbon kuti mercury igwirizane ndi sulfure kuti ipange mercury sulfide ndikuyiyika pa activated carbon. Yoyamba ili ndi mtengo wokwera ndipo ndi yoyenera pazochitika zomwe zili ndi mercury yambiri; Yomalizayi ili ndi mtengo wotsika wogwirira ntchito ndipo ndi yoyenera pazochitika zomwe zili ndi mercury yochepa.

Kumbali imodzi, mtengo wogwiritsira ntchito sieve ya hgsiv molecular ndi wokwera kwambiri; Kumbali ina, kuchuluka kwa mercury mu mpweya wodyetsa wa chipangizocho ndi kochepa. Chifukwa chake, kampaniyo ili ndi luso lopambana pakugwiritsa ntchito sulfure yomwe imayikidwa mu activated carbon pochotsa mercury.
