Uphahla Oluntanta Ngaphandle Lokugcina Uketshezi Oluvuthayo: Ukuphepha Kobunjiniyela Nokulawulwa Kokukhishwa Kwemfucuza
Ezimbonini zokucubungula uwoyela namakhemikhali, ukugcina uketshezi oluvuthayo olunamandla okushintsha kalula kuletha izinselele ezinzima zokuphepha nezemvelo. Lapho izinto eziphilayo eziguquguqukayo (VOCs) zihwamuka zibe ngumoya, zakha ingxube yomoya enokuvutha futhi zinomthelela ekulahlekelweni okukhulu kwemvelo.
Ithangi elinophahla oluntantayo olungaphandle (EFR) lakhelwe ngokukhethekile ukunciphisa lezi zingozi. Ngokungafani namathangi anophahla olungashintshi olushiya umgodi omkhulu womoya ngaphezu kobuso boketshezi, ithangi le-EFR linendawo yokugibela entanta ngqo phezu komkhiqizo ogciniwe, ikhuphuka yehle ngokwamanani empahla ukuze iqede indawo yomoya ngokuphelele.
Ukusebenza Kwamathangi Anophahla Oluntantayo Olungaphandle
Umgomo oyinhloko wobunjiniyela wethangi le-EFR ukuqedwa kwendawo yomoya (ullage). Ngokuntanta ngqo phezu kobuso boketshezi, uphahla luvimbela umhwamuko ukuba ungagcwali ngaphakathi komkhumbi.
Izingxenye eziyinhloko zesakhiwo zihlanganisa:
● I-Floating Deck: Ingaklanywa njengophahla lwe-pontoon, uphahla olunezitezi ezimbili, noma ingxube yangaphakathi/nangaphandle ngokuya ngomthwalo nezidingo zemvelo.
● I-Rim Seals: Izivalo eziguquguqukayo ezenziwe ngomshini noma ezigxiliswe oketshezini ezivala igebe phakathi kwedeski elintantayo nogobongo lwethangi, zivimba ukuvuza komhwamuko.
● Izitebhisi Ezigingqikayo Nezinhlelo Zokukhipha Amanzi: Zivumela abasebenzi ukuthi bafinyelele ngokuphepha ophahleni ngenkathi bephatha ngokuphepha ukuqoqwa kwamanzi emvula phezu kwedeski.
Izinzuzo Ezibalulekile Zobunjiniyela Zoketshezi Oluvuthayo
1. Ukuqedwa Kwezikhala Zomhwamuko Ovuthayo
Emathangini anophahla olungaguquki aqukethe uwoyela ongahluziwe noma uphethiloli, kuba nengxube eyingozi yomhwamuko nomoya endaweni engaphezulu. Ithangi le-EFR liyanciphisa lesi sikhala, kwehlise kakhulu ingozi yokuqhuma komhwamuko okuyinhlekelele.
2. Ukuncishiswa Okuqinile Kwezinto Ezikhishwayo Eziyingozi (VOC)
Imithetho yezemvelo iyalela ukulawulwa okuqinile kwezinto ezikhishwayo ezingabonakali. Amathangi e-EFR afakwe izivalo eziphumelelayo eziyinhloko nezesibili ezingemuva angakwazi ukunciphisa ukukhishwa kwe-hydrocarbon ngama-95% uma kuqhathaniswa nezinye izindlela ezinophahla olungaguquki, kuqinisekiswe ukuthobela ngokugcwele amazinga e-EPA.
3. Ukuthobela I-API 650 Nokuqina Kwesakhiwo
Yakhiwe ngokuqinile ngokulandela i-API 650 (Amathangi Ahlanganisiwe Okugcina Amafutha, Isithasiselo C), amathangi e-EFR enzelwe ukumelana nemimoya enkulu, ukuzamazama komhlaba okwenzeka endaweni ethile, kanye nengcindezi eguquguqukayo yamanzi ebangelwa izitokwe ezinkulu zika-petroleum.
Imininingwane Yezobuchwepheshe: Izinhlobo Zedekhi Nezinhlelo Zokuvula
Uhlobo Lwengxenye | Izinketho Ezihlukile | Umsebenzi Oyinhloko | Izinga Lobunjiniyela |
Isitayela Somphezulu Wophahla | I-Pontoon / I-Double-Deck | Ukuntanta nokusabalalisa umthwalo wesakhiwo | API 650 Appendix C |
Isivalo Somphetho Okuyisisekelo | Isivalo Se-Shoe / Esifakwe Uketshezi | Ivala igebe eliyindilinga eliyisisekelo, imisa ukuphuma komhwamuko omkhulu | Imihlahlandlela ye-API / EPA |
Isivalo Somphetho Sesibili | Isivalo Se-Wiper / I-Toe-Seal | Isithiyo esiyisipele sokumelana nokukhishwa okungagunyaziwe | Ukuthobela imithetho yezemvelo |
Uhlelo Lokukhipha Amanzi | Ipayipi Eliguquguqukayo / I-Siphon | Ilawula ukuqoqwa kwamanzi emvula endaweni entantayo | Amazinga e-ASME / API |
Inothi Lobunjiniyela: Ama-wind girder afakwa eduze nesiqongo segobolondo elivulekile ukuze kugcinwe ukuzungeza kwesakhiwo ngokumelana nemimoya enesivinini esikhulu eshaya indawo evulekile yomphetho.
Imibuzo Evame Ukubuzwa (FAQ)
Yini inzuzo eyinhloko yethangi elintanta ngaphandle phezu kwethangi elinophahla olungaguquki?
Inzuzo eyinhloko ukuqedwa kwesikhala somhwamuko ngaphezu koketshezi. Ngokuntanta ngqo emkhiqizweni, amathangi e-EFR avimbela ukunqwabelana kwemihwamuko eqhumayo, anciphisa kakhulu ukukhishwa kwe-VOC, futhi anciphisa ukulahleka komkhiqizo ngenxa yokuhwamuka.
Amanzi emvula alawulwa kanjani ophahleni oluntantayo lwangaphandle?
Ngenxa yokuthi uphahla luchayeke ezintweni zemvelo, uhlelo lokukhipha amanzi olwakhiwe—ngokuvamile oluhlanganisa ipayipi elihlangene noma eliguquguqukayo elixhunywe esitsheni esisemkhunjini—likhipha amanzi emvula ngaphansi kwethangi ngokuphephile ngaphandle kokungcolisa umkhiqizo ogciniwe.
Yimiphi imigomo elawula ukwakhiwa kophahla oluntantayo lwangaphandle?
Amathangi e-EFR aklanywa, akhiqizwa, futhi ahlolwa ngokuvumelana namazinga omhlaba, ikakhulukazi i-API 650 Appendix C yamathangi ensimbi ahanjisiwe okugcina uwoyela, kanye nezidingo zokuvikela umlilo ezichazwe ku-NFPA 30.
Ingabe amathangi angaphandle anophahla oluntantayo afanele zonke izinhlobo zamakhemikhali?
Afanele kakhulu uketshezi oluvuthayo nolungavuthi kahle olunamandla aphakathi nendawo kuya phezulu njengowoyela ongahluziwe, uphethiloli, udizili, ne-naphtha. Kumakhemikhali abolayo kakhulu noma imikhiqizo ezwa ukungcola kwamanzi emvula, amathangi anophahla oluntantayo ngaphakathi (IFR) noma amathangi anophahla oluntantayo angaphandle anedome avame ukukhethwa.
