Uphahla Oluntantayo Olungaphandle Lwamathangi Kawoyela Angaphezulu Komhlaba: Umklamo, Amazinga, Nokulawulwa Kokukhishwa Kwezinto
Engqalasizindeni enkulu yamafutha negesi emaphakathi naphansi, ukuphatha inani elikhulu lama-volatile hydrocarbons kudinga ubunjiniyela obuthuthukile. I-API 650 External Floating Roof Tank (EFRT) iyindinganiso yomhlaba wonke yokugcina ngokuphepha uketshezi olunomfutho ophakeme womhwamuko, njengowoyela ongahluziwe, uphethiloli, nezinto ezingavuthiwe ezinzima.
Ilawulwa yi-API 650 Appendix C, lezi zitsha zokugcina eziyisiyingi ezivulekile zisebenzisa uphahla oluntanta ngqo ebusweni buketshezi. Ngokukhuphuka nokwehla ngamazinga empahla, idekhi iqeda isikhala somhwamuko lapho amagesi ayingozi evame ukuhlanganiswa khona, inciphisa kakhulu ukulahleka okubangelwa ukuhwamuka futhi inciphise izingozi zomlilo.
Ukuhlelwa Okumqoka Kwezakhiwo Zophahla Oluntantayo Olungaphandle
I-API 650 Isithasiselo C ichaza imingcele eqinile yokuhlelwa kwesakhiwo samadekhi antantayo angaphandle. Ngenxa yokuthi lezi zophahla zivezwa ngqo ezintweni zemvelo, kumele zikwazi ukumelana nemithwalo enzima yemishini neyesimo sezulu. Izinga lichaza izinhlobo ezimbili eziyinhloko:
Uhlobo Lophahla Oluntantayo | Incazelo Yesakhiwo | Okufaneleka Kakhulu |
Uphahla Lohlobo Lwe-Pontoon Olunedeski Eliyedwa | Lunedeski eliqhubekayo eliphakathi lensimbi elizungezwe umugqa wamaphontoni angaphandle ahlukanisiwe, angangeni moya. Amaphontoni ahlinzeka ukuntanta okugxilile, kuyilapho ideski eliphakathi ligoba ngokuguquguqukayo. | Amathangi okugcina angaphezulu omhlaba aphakathi nendawo kuya kwancane ububanzi. |
Uphahla Oluntantayo Olunezitezi Ezimbili | Luhlanganisa amakhava ensimbi aphezulu naphansi ahlukaniswe yigridi yangaphakathi yezindonga zesakhiwo, okudala amakamelo omoya avaleke ngokuphelele kuyo yonke indawo. | Amathangi okugcina amakhulu kakhulu ububanzi (ngokuvamile adlula amafidi angu-300 / amamitha angu-91.5). |
Izinga Lokulawula kanye Nezinhlaka Zokuthobela
Okokuqukethwe okungozi kwe-hydrocarbon, ubuqotho bezinto kanye nokuthobela umklamo akuxoxiswana ngakho. Umklamo wethangi kanye nokunakekelwa kulawulwa izinhlaka ezimbili ezihlukene ze-American Petroleum Institute:
● API 650 (Umklamo & Ukwakhiwa): Ibeka izidingo zesakhiwo zokwenziwa kwethangi elisha. I-Appendix C ikakhulukazi imisa izindinganiso zokusebenza zophahla oluntantayo olungaphandle, okuhlanganisa izidingo zokuntanta (ukuqinisekisa ukuthi uphahla luhlala luntanta ngisho noma izigcawu ezimbili ezincikene zomkhumbi zephukile) kanye nezibalo eziphelele zomthwalo wemvelo.
● API 653 (Ukuhlola, Ukulungisa, & Ukwakha Kabusha): Ilawula umjikelezo wokusebenza wezimpahla ezisemsebenzini, ichaza kabanzi izindlela zokuhlola okuvamile okubonakalayo, ukuhlolwa kwangaphandle kweminyaka emi-5 ngabasebenzi abaqinisekisiwe, kanye nokuhlolwa okuphelele kwesakhiwo kwangaphakathi.
Izinzuzo Ezibalulekile Zobunjiniyela Zamathangi Ophahla Oluntantayo Olungaphandle
1. Ukulahleka Komhwamuko Nokuncishiswa Kokukhishwa Kwe-VOC: Ngokuhlala kuthintana ngqo nomkhiqizo owuketshezi, ama-EFRT aqeda izikhala zomhwamuko, evimbela ngempumelelo ukuphuma kwama-volatile organic compounds emoyeni.
2. Ukuphepha Okuthuthukisiwe Komlilo: Ukususa ingxube ye-vapor nomoya evuthayo ngaphezu koketshezi kunciphisa kakhulu ingozi yokuqhuma okubangelwa umbani noma izinhlansi ezingashisi.
3. Ukuzivumelanisa Nokushintsha Okuguquguqukayo: Uhlelo lwamadeski antantayo oluyizingxenye ezihlukene luvumelana kalula nokwanda ngenxa yokushisa kwansuku zonke, imijikelezo yokugcwalisa, kanye nemisebenzi yokukhipha ngaphandle kokubopha kwesakhiwo.
4. Izinhlelo Zokugwinya Ezinembile: Ukuhlelwa kwesigxivizo esiyinhloko nesesibili kwamanje kuvala isikhala esiyindilinga phakathi konqenqema lophahla oluntantayo nogobongo lwethangi, kuqinisekisa ukugcinwa okucishe kuphelele.
Imibuzo Evame Ukubuzwa (FAQ)
Umbuzo: Uyini Uphahla Lwangaphandle Oluntantayo Lwethangi (EFRT)?
Impendulo: I-EFRT iyithangi elingaphezulu komhlaba, elivulekile eliyisilinda elihlonyiswe ngedekhi entanta ngqo phezu kwetshe eliwuketshezi eliguquguqukayo eligcinwayo (njengowoyela ongahluziwe noma uphethiloli), lisusa isikhala somhwamuko futhi linciphisa ukukhishwa kwesisindo.
Umbuzo: Yiliphi izinga elilawula ukwakheka kophahla oluntantayo lwangaphandle?
Impendulo: Ukuklanywa nokwakhiwa kophahla oluntantayo lwangaphandle lwamathangi okugcina angaphezulu komhlaba kulawulwa ngokuqinile yi-API 650 Isijobelelo C.
Umbuzo: Yini umehluko omkhulu phakathi kophahla oluntantayo lohlobo lwe-pontoon nolwe-deck ephindwe kabili?
A: Uphahla lohlobo lwe-Pontoon lusebenzisa indandatho yangaphandle yamakamelo angangeni umoya anesitezi esisodwa sensimbi phakathi nendawo, okulungele amathangi aphakathi nendawo. Uphahla olunezitezi ezimbili lunamakhava ensimbi aphezulu naphansi avaleke kuyo yonke indawo, okunikeza ukuntanta okuphezulu nokuvikela ukushisa emathangini amakhulu kakhulu.
Q: Uphahla oluntantayo lwangaphandle lunciphisa kanjani izingozi zemvelo nezomlilo?
A: Ngokuntanta ngqo phezu koketshezi, uphahla lususa izikhala ezinkulu eziqhumayo zomhwamuko ezivame ukutholakala emathangini anophahla olungashintshi, ngaleyo ndlela lunciphisa ukulahleka kwe-hydrocarbon emhwamukweni futhi lunciphise izingozi zokuthungela umlilo.
