Kupita Patsogolo kwa Ukadaulo wa Maselo Osiyanasiyana Kumawonjezera Kuchotsa Sulphur ndi Kuthetsa Madzi M'thupi Mwachangu mu Kukonza Gasi

Makampani opanga gasi lachilengedwe akuwona kupita patsogolo kwakukulu muukadaulo wochotsa sulphur mu sieve ya molecular ndi ukadaulo wochotsa madzi m'thupi, chifukwa cha kufunikira kwakukulu kwa mafuta oyera kwambiri komanso magwiridwe antchito abwino. Zatsopano zaposachedwa zikuyang'ana kwambiri pakukweza kukhazikika kwa catalyst ndi kuthekera kobwezeretsanso mphamvu mu zida zamadzi m'thupi, makamaka pamakina a LNG ndi NGL omwe achotsedwa mu gasi lachilengedwe.

Patsogolo pali kupanga ma sieve a masoporous molecular okhala ndi cobalt-doped omwe amalumikizidwa ndi N,N-dihydroxypyromellitimide (Co-SBA-15-NDHPI), omwe amasonyeza kukhazikika kwakukulu panthawi ya catalytic oxidative desulfurization. Chophatikiza cha organic-inorganic ichi chimalimbitsa mphamvu yogwirizana pakati pa zigawo zogwira ntchito ndi zothandizira zokhala ndi mabowo, zomwe zimapangitsa kuti sulfide-to-sulfone ikhale yogwira ntchito bwino komanso yolimbana ndi kuzimitsa.

Yogwirizana Mayunitsi Ochotsa Madzi M'thupi Kugwira Ntchito Kwambiri
Mapangidwe amakono a zida zochotsera madzi m'thupi amaphatikiza kupita patsogolo kumeneku ndi njira zabwino zogwirira ntchito:

Ma modular configurations: Magawo okhazikika pa skid okhala ndi automated switching pakati pa adsorption, regeneration, ndi cooling cycles (ma system awiri kapena atatu) amalola ntchito yopitilira ya -70°C ya dewpoint yofunikira kwambiri pa LNG/Njira za NGL

Kubwezeretsa mphamvu: Zotenthetsera zamagetsi kapena zamagetsi tsopano zimasinthanso ma sefa a molekyulu pa 230-300°C pogwiritsa ntchito mpweya wouma, kubwezeretsa mphamvu ya ma adsorption pamene kuchepetsa kugwiritsa ntchito mphamvu ndi 30%.

Kuwongolera zinthu zambiri zoipitsa: Ma sieve a mamolekyu a m'badwo wotsatira nthawi imodzi amalunjika ku H₂S, SO₂, ndi nthunzi ya madzi kudzera m'mapangidwe a ma pore opangidwa mwaluso—ma pore ochepa (

Kukhazikitsa ndi Kuchita Bwino M'munda
Mu gawo la Shandong LNG ku China, mayunitsi okonzedwanso a molecular sieve adachepetsa kuchuluka kwa kubwezeretsedwanso kwa zinthu ndi 40% pomwe adasungabe mawonekedwe a mpweya wazinthuzo pansi pa 0.1 ppm sulfure compounds ndi -70°C dew point. Mofananamo, Permian Basin Kubwezeretsa kwa NGL Zipangizozi zimanena kuti nthawi yogwiritsira ntchito sieve yakhala yayitali ndi 15% mutasintha kugwiritsa ntchito ma sieve a molecular a ZSM-5 a vanadium, zomwe zimapangitsa kuti thiophene desulfurization igwire bwino ntchito ndi 11% poyerekeza ndi zipangizo wamba.

"Kuphatikizana kwa zinthu zosungunula sulfur zomwe zimakhala zolimba kwambiri m'malo osungira madzi m'thupi kumayimira kusintha kwa njira. Zomera sizikufunanso mayunitsi osiyana kuti zichotse sulfure ndi madzi, zomwe zimachepetsa CAPEX ndi 25% pomwe zimapeza mpweya wopangidwa ndi mapaipi pang'onopang'ono." — Jiangsu Rudy Mtsogoleri wa Uinjiniya wa Petrochemical

Popeza malonda apadziko lonse a LNG akuyembekezeka kukula ndi 70% pofika chaka cha 2040, zatsopano za sieve ya molecular zikukonzekera kuthandizira zolinga ziwiri zamakampaniwa za kukula ndi kuchepetsa utsi. Kafukufuku wopitilira akuyang'ana ma sieve ochokera ku MOF omwe ali ndi mphamvu zosiyanitsa ma molecular kuti nthawi imodzi achotse mitundu ya mercury, madzi, ndi sulfure m'zida zotsukira mpweya wachilengedwe za m'badwo watsopano.
