Ama-Floating Roofs Amathangi Okugcina: Umhlahlandlela Wezobunjiniyela Nokuklama
Uphahla oluntantayo luyingxenye yesakhiwo ekhethekile esetshenziswa emathangini okugcina aphezulu (ama-AST) ukugcina izinto eziyimpophoma, njengamafutha aluhlaza, uphethiloli, kanye ne-jet fuel. Ngokungafani namathangi anophahla oluqinile, uphahla oluntantayo luhlala ngqo phezu koketshezi, lukhwele futhi lwehla nezinga loketshezi. Lo mklamo "wokubopha okucacile" ususa ngokuphelele isikhala sezimpondo (i-ullage) lapho izinto ezivutha amalangabi zingaqoqana khona, kunciphisa kakhulu ukukhishwa kwe-VOC, kuvimbele ukubola komkhiqizo, futhi kunciphise ubungozi bomlilo nokuqhuma.
1. Izimiso zobunjiniyela: Kungani ama-Floating Roofs?
Inhloso eyinhloko ye-floating roof ukuphatha umusi. Ethangini elingaphezulu liqinisekile, isikhala phakathi koketshezi nophahla sigcwaliswe umoya kanye nomusi kaphethiloli. Lokhu kudala izingozi ezintathu ezibalulekile:
● Ukulahleka komkhiqizo: Izilinganiso eziphakeme zokushintsha kwamanzi ezinto eziphilayo (VOCs).
● Ingozi yomlilo/ukuqhuma: Isikhala somusi sivame ukuqukethe ingxube evutha kalula.
● Ukugqwala: Ukujiya emkhathini womusi kungasheshisa ukwehla kophahla lwethangi kanye nodonga oluphezulu.
Ngokubeka uphahla oluncibilikayo ngqo phezu koketshezi, amathangi ane-floating roof anciphisa isikhala somusi sibe zero, kuqinisekiswe ukuzinza komkhiqizo kanye nokuthobela imvelo.
2. Ukuhlaziywa Okulinganisiwe: Izindlu Zophahla Zangaphakathi vs. Zangaphandle Ezintantayo
Kunezinhlobo ezimbili eziyinhloko zezindlu zophahla ezintantayo, ezichazwa ngokuthi ngabe zivaliwe yindlu yethangi emile noma zivezwe ezintweni zemvelo.
Isici | Uphahla Lwangaphandle Oluntantayo (EFR) | Uphahla Lwangaphakathi Oluntantayo (IFR) |
Ukucushwa | Ithangi elingaphezulu livulekile | Ithangi elingaphezulu liqinisekile eline-floater yangaphakathi |
Ukuthobela i-API | I-API 650, iSihlomelo C | I-API 650, iSihlomelo H |
Ukuvikelwa kwesimo sezulu | Akukho (Kubhekene nemvula/iqhwa) | Phezulu (Kuvikelwe yindlu emile) |
Ukulungisa | Phezulu (Izinhlelo zokudonsa amanzi/izimpawu) | Phansi (Indawo evikelwe) |
Ukulawulwa kokukhishwa | Kuhle kakhulu (Ngezimpawu zesibili) | Okungcono kakhulu (Isithiyo sesibili) |
Izindleko | Ukutshalwa kwezimali kokuqala okuphansi | Ukutshalwa kwezimali kokuqala okuphezulu |
● Izindlu Zophahla Zangaphandle Ezintantayo (EFRs): Zenzelwe amathangi anobubanzi obukhulu kakhulu. Zidinga izinhlelo eziyinkimbinkimbi zokudonsa amanzi ukuze kukhishwe amanzi emvula aqoqekile kuphahla ukuze kuvinjelwe uphahla ukuthi lungacwazi.
● Izindlu Zophahla Zangaphakathi Ezintantayo (IFRs): Zilungele amathangi amancane kuya aphakathi noma izindawo ezinemvula enkulu. Indlu yangaphandle emile isusa isidingo sokudonsa amanzi uphahla futhi ivikela intantayo ezimweni zezulu ezinzima.
3. Izingxenye Ezibalulekile Zokuphepha kanye Nomklamo
Ukugcina ubuqotho bokwakhiwa kanye nokuthobela imithetho, izimpahla eziwumgqomo eziwumgqomo zihlanganisa izingxenye eziningana ezinokusebenza okuphezulu:
● Izinhlelo Zesigcawu Somkhawulo: Indawo eyinhloko phakathi kwedeski lophahla kanye ne-shell yethangi. Izimpawu zezicathulo zemishini kanye nezimpawu ezifakwe uketshezi zivame ukusetshenziswa ukuvimbela ukuvuza kukagesi emkhawulweni wethangi.
● Izinhlelo Zokuhlala (Ama-pontoon): Uphahla kumele luhlale luhlala ngisho nasezimweni "ezimbi kakhulu", njengokugcwala kwama-pontoon amabili aseduze. Izindinganiso zomklamo (njenge-API 650) zidinga izibalo eziqondile zokuhlala ukuze kuqinisekiswe ukuthi uphahla alusoze lwacwilisa, okungaholela ekukhululweni komkhiqizo okubhubhisayo.
● Izimpondo Zokuhlala: Zivame ukusetshenziswa ngokuhlangana neziphahlahla eziwumgqomo, lezi zinhlelo zidonsa uketshezi kusuka ngaphansi nje kwendawo, ziqinisekisa ukuthi umkhiqizo ohlanzekile, ongabikho sedimenti kuphela ondliwayo.
4. Izindinganiso Zomthetho (API 650 & API 653)
Ubunyezi nokugcinwa kwezimpahla ezingezansi kuyalelwa yimikhomba eqinile yomkhakha. Ochwepheshe kufanele baqinisekise ukuthi konke ukwakhiwa okusha nokugcinwa kuhlangabezana nalezi zilinganiso:
● API 650 (Ukwakhiwa Okusha):
○ Isihlomelo C: Sichaza izidingo zezimpahla zangaphandle ezingezansi.
○ Isihlomelo H: Sichaza izidingo zezimpahla zangaphakathi ezingezansi.
● API 653 (Ukuhlola Nokugcinwa): Lokhu kuyisilinganiso esiqondile sokuphathwa kwempilo yamathangi okugcina. Kubeka imvamisa yokuhlola "kusebenza" nokuthi "akusebenzi", okuhlanganisa ubuqotho bezimpawu, ukugqwala kwedekhi, nokuhlola ukuzingela kwamaphonti.
5. Imibuzo Evame Ukubuzwa (FAQ)
Umbuzo: Ingabe uphahla oluncwebezelayo lungabambeka ezintweni zangaphakathi ethangini?
Impendulo: Yebo, lokhu kuyingozi eyaziwayo yokusebenza. Uma uphahla lubambeka (isibonelo, kusigxobo esisekelayo noma ku-coil yokushisa) ngenkathi izinga loketshezi lehla, kungaholela ekwehlulekeni komklamo. Imiklamo yesimanje inciphisa izithiyo zangaphakathi, futhi abasebenzisi abaningi basebenzisa imilenze "ezizilinganisayo" ukuvimbela ukuguduka.
Umbuzo: Kungani izimpawu zesibili zinconywa noma ngabe isimpawu sokuqala sifakiwe?
Impendulo: Ngenkathi isimpawu sokuqala sihlinzeka ngomgoqo omkhulu, izimpawu zesibili zibalulekile ekulawuleni umusi "wesikhala somngcele". Imithetho yezemvelo (njengezindinganiso ze-EPA) ivame ukufuna izimpawu ezimbili ukuze kuncishiswe kakhulu ukukhishwa kwe-VOC futhi kunikezwe ukubuyekezwa uma isimpawu sokuqala siba sibi.
Umbuzo: Ungalusingatha kanjani uhlobo lwemvula ephahla langaphandle oluncwebezelayo?
A: Izindlu zangaphandle zisebenzisa izinhlelo ezikhethekile zokudonsa amanzi ophahleni. Lezi ngokuvamile izimpondo eziguquguqukayo noma amapayipi ensimbi axhunyiwe ahamba kusuka endaweni yokuqoqa amanzi ophahleni aye phansi ethangini, avumela amanzi ukuba adalele ngaphandle noma ngabe uphahla luhamba phezulu naphansi.
Izindlu ezintantayo ziyindlela engcono kakhulu yokugcina ama-hydrocarbon anomoya ngokuphepha nangempumelelo. Ngokukhipha indawo yomoya nokuhlinzeka ngomgoqo oqinile phakathi koketshezi nomoya, lezi zinhlelo azivikeli nje umkhiqizo kodwa futhi ziqinisekisa ukuthobela imvelo ngokuqinile. Noma ngabe ukuklama indawo entsha noma ukuthuthukisa impahla endala, ukuthobela izindinganiso ze-API 650 kanye ne-653 kuhlala kuyisisekelo sempumelelo yokusebenza.
Ngabe njengamanje uhlola iphrojekthi yethangi yokugcina umkhiqizo onomoya ophezulu, noma ngabe ufuna ukwenza kahle uhlelo olukhona lophahla oluntantayo ukuze uhlangane nezindinganiso ezintsha zokukhishwa kwemvelo?
