Kusankha njira yochotsera madzi m'thupi pogwiritsa ntchito mpweya wachilengedwe
Chiyambi cha Njira
Kupezeka kwa madzi mu mpweya wachilengedwe nthawi zambiri kumabweretsa mavuto aakulu: madzi ndi mpweya wachilengedwe zimapanga madzi pansi pa mikhalidwe ina, zomwe zimatseka mapaipi; kuphatikiza apo, kuti zikwaniritse zizindikiro za kuchuluka kwa madzi (kapena mame point) a zinthu za mpweya wachilengedwe, kusowa madzi m'thupi ndikofunikira.
The kusowa madzi m'thupi chifukwa cha mpweya wachilengedwe Njirayi nthawi zambiri imaphatikizapo:
- Kusowa madzi m'thupi chifukwa cha kutentha kochepa
- Kusakaniza kolimba kwa desiccant
- Kuyamwa kwa zosungunulira
- Kulekanitsa kwa nembanemba
Kusowa madzi m'thupi chifukwa cha kuzizira pang'ono nthawi zambiri kumaphatikizidwa ndi kubwezeretsa kwa hydrocarbon pang'ono Mapulojekiti. Mpweya wachilengedwe ukauma chifukwa cha kuzizira, mpweya wachilengedwe umafunika kukhala ndi mphamvu yokwera kapena gwero lakunja lozizira. Popeza umafunika kupanikizika kapena gwero lakunja lozizira likaperekedwa, sikotsika mtengo pa chipangizochi.
Njira zodziwika bwino zogwiritsira ntchito njira yothira madzi yolimba ya desiccant ndi njira ya silica gel, njira ya molecular sieve kapena kuphatikiza njira ziwirizi. Ndalama zomwe zimagwiritsidwa ntchito komanso zomwe zimagwiritsidwa ntchito pogwiritsa ntchito njira yothira madzi ndi zokwera kuposa zomwe zimagwiritsidwa ntchito pogwiritsa ntchito chipangizo chothira madzi chotchedwa glycol.
Kuyamwa zosungunulira ndiyo njira yomwe imagwiritsidwa ntchito kwambiri. Ngakhale kuti pali zosungunulira zambiri zomwe mungasankhe, zipangizo zambiri zimagwiritsa ntchito zosungunulira za glycol. Kuyerekeza kwa zosungunulira zosiyanasiyana za madzi m'thupi kukuwonetsedwa patebulo poyerekeza zosungunulira za madzi m'thupi.
Kuyerekeza kwa zosungunulira madzi m'thupi
| Chosungunulira madzi m'thupi | ubwino | kusowa | Ndemanga |
| Madzi a Calcium chloride | Mtengo wotsika wogwirira ntchito komanso zida zosavuta | Zipangizozo zachita dzimbiri kwambiri, dontho la mame ndi laling'ono (pafupifupi 11°C), ndipo H2S mu mpweya wachilengedwe imapanga mvula. | Sizigwiritsidwa ntchito kawirikawiri masiku ano, makamaka m'zitsime za gasi zakutali komanso m'malo ozizira kwambiri. |
| Yankho lamadzi la lithiamu chloride | Mame amatha kutsika kufika pa 22 ~ 36℃, zomwe siziwononga kwambiri zida kuposa madzi a calcium chloride. | Zokwera mtengo | Amagwiritsidwa ntchito makamaka pochotsa madzi m'thupi |
| Diethylene glycol yankho | Yankho lokhazikika silidzalimba, zosungunulira zimakhala zokhazikika kutentha kogwira ntchito, komanso zimakhala ndi hygroscopicity yambiri | Mame amachepa ndi 28℃, zomwe ndi zochepa kuposa za triethylene glycol solution. Kutayika kwa zinthu zomwe zasungidwa ndi kwakukulu kuposa kwa triethylene glycol, ndipo ndalama zomwe zagwiritsidwa ntchito pa chipangizochi ndi zambiri. | Sizigwiritsidwa ntchito kwambiri mumakampani opanga gasi wachilengedwe |
| yankho la triethylene glycol | Yankho lokhazikika silidzalimba, chosungunuliracho chimakhala chokhazikika pa kutentha kogwira ntchito, ndipo hygroscopicity ndi yayikulu kwambiri. Kuthamanga kwa nthunzi kumakhala kochepa, kutayika kwa kunyamula kumakhala kochepa, ndipo mame amatha kutsika kufika pa 40℃ | Ndalama zomwe chipangizochi chili nazo ndi zambiri, ndipo yankho lake limakhala ndi chizolowezi chotulutsa thovu | Ndi njira yogwiritsidwa ntchito kwambiri pochotsa madzi m'thupi mumakampani opanga gasi wachilengedwe |
Popeza triethylene glycol ili ndi madontho ambiri a dew point, mtengo wotsika komanso ntchito yodalirika, ndiyo yotsika mtengo kwambiri pakati pa mankhwala a glycol. Chifukwa chake, chipangizochi chimagwiritsa ntchito triethylene glycol yothandiza kusowa madzi m'thupi.
Kapangidwe ka zida zogwirira ntchito
1) Chigawo cha Triethylene glycol chochepetsa madzi m'thupi:
(1) Nsanja yoyamwitsa (kuphatikizapo chodzaza)
(2) Chosinthira kutentha cha TEG chosagwiritsa ntchito mpweya
2) Gawo lokonzanso la triethylene glycol:
(1) Fyuluta yamakina yolemera ndi Glycol
(2) Fyuluta ya kaboni yodzaza ndi glycol yokhala ndi madzi ambiri
(3) Thanki yosungira mafuta
(4) Chosinthira kutentha chamadzimadzi cha triethylene glycol chopanda mafuta ambiri
(5) Pampu yoyendera magazi ya Triethylene glycol
(6) Chipangizo chophatikizana chokonzanso triethylene glycol chimaphatikizapo:
(a) Nsanja yokonzanso ya triethylene glycol
(b) Chotenthetsera cha TEG.
(c) Thanki ya Triethylene glycol
(d) Choyatsira moto
