Horumar laga sameeyay Tiknoolajiyadda Shaandhada Molecular-ka ayaa kor u qaadaysa Nadiifinta iyo Waxtarka Fuuq-baxa ee Hagaajinta Gaaska
Warshadaha wax soo saarka gaaska dabiiciga ah ayaa ku sugan horumar la taaban karo oo ku saabsan teknoolajiyada nadiifinta shaandhada molecular iyo fuuq-baxa, taasoo ay keentay baahida sii kordheysa ee qeexitaannada shidaalka ee aadka u nadiifsan iyo hufnaanta hawlgalka. Hal-abuurrada dhowaan la sameeyay waxay diiradda saarayaan kor u qaadista xasilloonida kicinta iyo awoodaha dib-u-cusboonaysiinta ee qalabka fuuq-baxa gaaska dabiiciga ah, gaar ahaan warshadda LNG iyo soo kabashada NGL ee ka timaadda codsiyada gaaska dabiiciga ah.
Horumarka ugu horreeya waa horumarinta shaandhada mesoporous ee kobalt-doped oo lagu tallaalay N,N-dihydroxypyromellitimide (Co-SBA-15-NDHPI), taas oo muujinaysa xasillooni rikoodh ah inta lagu jiro desulfurization-ka catalytic oxidative. Isku-darkaan organic-inorganic-ka ah wuxuu xoojiyaa saameynta isku-dhafka ah ee u dhaxaysa qaybaha firfircoon iyo taageerooyinka daloolada leh, isagoo si weyn u hagaajinaya hufnaanta beddelka sulfide-to-sulfone isagoo iska caabinaya joojinta.
Isku dhafan Qaybaha Qallajinta-Ka-saarista Sulfurization Kor u qaadid
Naqshadaha cutubyada casriga ah ee fuuq-baxa waxay ku daraan horumarkan iyadoo la adeegsanayo qaab-dhismeedyo hawlgal oo la hagaajiyay:
Qaabeynta qaabaysan: Cutubyo simbiriirixan leh oo leh beddel otomaatig ah oo u dhexeeya nuugista, dib-u-cusboonaysiinta, iyo wareegyada qaboojinta (nidaamyada laba-ama saddex-tallaabo ah) waxay awood u siinayaan hawlgal joogto ah oo biyo-dhaamis ah -70°C oo muhiim u ah LNG/Hababka NGL
Waxtarka dib u soo noolaynta: Kuleyliyeyaasha tooska loo shido ama kuwa korontada ku shaqeeya ayaa hadda dib u soo nooleeya shaandhada molecular-ka heerkul ah 230-300°C iyagoo isticmaalaya qulqulka gaaska qalalan, iyagoo soo celinaya awoodda nuugista iyadoo la dhimayo isticmaalka tamarta ilaa 30%
Xakamaynta wasakhowga badan: Sifeeyayaasha molecular-ka ee jiilka xiga waxay si isku mid ah u bartilmaameedsadaan H₂S, SO₂, iyo uumiga biyaha iyada oo loo marayo qaab-dhismeedka daloolada ee loo habeeyay - daloolo yar yar (
Hirgelinta Goobta iyo Waxqabadka
Terminaalka Shandong LNG ee Shiinaha, cutubyada fuuq-baxa shaandhada molecular-ka ee la casriyeeyay ayaa hoos u dhigay soo noqnoqoshada dib-u-cusboonaysiinta 40% iyadoo la ilaalinayo qeexitaannada gaaska badeecadaha ee ka hooseeya 0.1 ppm isku-dhafka sulfur iyo dhibicda dharabka -70°C. Sidoo kale, Permian Basin Soo kabashada NGL Xarumihii ayaa soo sheegay in cimriga shaandhada uu ka badan yahay 15% ka dib markii loo beddelay shaandhada molecular-ka ZSM-5 ee vanadium-modified, taas oo kor u qaadaysa hufnaanta thiophene desulfurization 11% marka loo eego agabka caadiga ah.
"Isku-darka qaybaha desulfurization-ka ee xasilloonida sare leh ee ku jira munaaradaha fuuq-baxa waxay ka dhigan tahay isbeddel qaab-dhismeed. Dhirtu uma baahna cutubyo gaar ah oo loogu talagalay ka saarista sulfur iyo biyaha, taasoo CAPEX ku dhimaysa 25% iyadoo la gaarayo gaaska gaarka ah ee dhuumaha hal tallaabo." - Jiangsu Rudy Hogaamiyaha Injineerinka Kiimikada Batroolka
Iyada oo ganacsiga caalamiga ah ee LNG la saadaalinayo inuu kordho 70% marka la gaaro 2040, hal-abuurka shaandhada molecular-ka ayaa diyaar u ah inay taageeraan yoolalka laba-geesoodka ah ee warshadaha ee ah in la kordhiyo baaxadda iyo yaraynta qiiqa. Cilmi-baarista socota waxay bartilmaameedsanaysaa shaandhada ku salaysan MOF oo leh awoodo kala soocid molecular ah si ay si isku mid ah uga saaraan noocyada meerkuriga, biyaha, iyo sulfur ee qalabka fuuq-baxa gaaska dabiiciga ah ee jiilka xiga.
