Ukusetshenziswa Kwezinzwa Zegesi Ezingavuthi Emkhakheni Wezimboni waseSaudi Arabia

Isakhiwo sezimboni saseSaudi Arabia sibuswa uwoyela, igesi yemvelo, amakhemikhali kaphethroli, amakhemikhali kanye nezimayini. Lezi zimboni ziletha izingozi ezinkulu zokuvuza kwegesi evuthayo, eqhumayo, neyingozi. Ngakho-ke, izinzwa zegesi ezingaqhumi ziphakathi kwezingxenye ezibaluleke kakhulu ezinhlotsheni zayo zokuphepha kwezimboni.

Isizinda Secala kanye Nezidingo Eziyinhloko

• Izici Zemboni: Lonke uchungechunge lokuhlinzekwa kukawoyela negesi eSaudi Arabia—kusukela ekubholeni nasekukhipheni umfula ongaphezulu kuya ekuthuthweni nasekuhlanzeni umfula ophakathi, kanye nokukhiqizwa kwe-petrochemical ongezansi—kubandakanya ama-hydrocarbon (i-methane, i-propane, ama-VOC, njll.) kanye namagesi anobuthi (i-Hydrogen Sulfide H₂S, i-Carbon Monoxide CO, njll.).
• Izidingo Zemvelo: Lezi zindawo zivame ukuhlukaniswa njengezindawo eziyingozi (eziqhumayo). Noma yimuphi umshini kagesi osetshenziswayo kumele ube nesitifiketi esingaqhumi ukuze uvimbele umshini ukuthi ungabi umthombo wokushisa.
• Abashayeli Abalawulayo: Izindinganiso zokuphepha eziqinile ezivela kwi-Saudi Arabian Standards Organisation kanye neziqhwaga zezwe ezifana ne-Saudi Aramco (isib., izindinganiso ze-SAES ze-Aramco) ziyala ukufakwa kwezinhlelo zokuthola igesi eziqinisekisiwe kuzo zonke izindawo eziyingozi.

Icala Elijwayelekile: Uhlelo Oluhlanganisiwe Lokuthola Igesi e-Saudi Aramco's Jazan Refinery

1. Ukubuka Konke Kwephrojekthi:

• Indawo: Idolobha Lezomnotho laseJazan, eSaudi Arabia.
• Isikhungo: I-Jazan Refinery iyindawo enkulu ehlanganisiwe yokucwenga, amakhemikhali kaphethroli, kanye nokukhiqizwa kukagesi.
• Inselele: Lesi sikhungo sicubungula inani elikhulu likawoyela ongahluziwe one-sulfur ephezulu, okusho ukuthi kunengozi enkulu kakhulu yokuvuza kwe-H₂S. Ngaphezu kwalokho, sonke isitshalo siqukethe umoya wegesi ovuthayo. Indawo eshisayo ephezulu, enomswakama ophezulu, enosawoti omningi osogwini ibeka izinselele ezinkulu ekuqineni kwemishini.

2. Izimo Zokusetshenziswa Kwezinzwa Zegesi Ezingaqhumi:
Esikhungweni esikhulu kangaka, izinzwa zegesi ezingaqhumi zifakwa ezindaweni eziningi ezibalulekile:

• Izivalo Zephampu Nezokucindezela: Lezi mishini ezijikelezayo ziyizindawo ezivame ukuvuza. Kufakwe izinzwa ezingavumeli ukuqhuma ze-Catalytic Bead noma i-Infrared ukuze ziqaphe amagesi avuthayo.
• Indawo Yethangi Lokugcina Izinto (eduze kwezindawo zokungenisa umoya kanye nezingalo zokulayisha): Umhwamuko ungakhishwa ngesikhathi sokudluliselwa komkhiqizo noma “ekuphefumuleni” ngenxa yokushintsha kwezinga lokushisa. Izinzwa zihlinzeka ngokuqapha okuqhubekayo lapha.
• Izindawo Zeyunithi Yenqubo (isb., ama-reactor, amakholomu okuhlukaniswa): Ama-gas detector agxilile afakwa kuma-flange kanye nokuxhumeka kwama-valve lapho i-H₂S namagesi avuthayo kungenzeka ukuthi akhona. Lawa ma-sensor avame ukuba nesitifiketi se-Intrinsic Safety (Ex i), okusho ukuthi awakwazi ukukhipha amandla anele okubangela ukusha, noma ngabe ahluleka ngenkathi esebenza.
• Izinhlelo Zokuthuthwa Kwendle Nokukhipha Amanzi: Lezi zindawo ezivalekile zingaqoqa amagesi avuthayo (isb., i-methane). Izinzwa zohlobo lokusabalalisa noma ezivikela ukuqhuma ezisizwa yiphampu zisetshenziselwa ukuqapha.
• Ukungenisa Umoya Kwamagumbi Okulawula Nezindawo Zokuhlala: Kufakwa izinzwa ezindaweni zokungenisa umoya kulezi zakhiwo ukuvimbela amagesi anobuthi noma avuthayo ukuthi angadonselwa ngaphakathi, okuqinisekisa ukuphepha kwabasebenzi.

3. Ubuchwepheshe Bezinzwa Nezinhlobo Ezingavimbeli Ukuqhuma:

• Izimiso Zobuchwepheshe:
  • Amagesi Avuthayo: Ngokuyinhloko kusetshenziswa ubuchwepheshe be-Catalytic Bead kanye ne-Non-Dispersive Infrared. I-NDIR ithandwa kakhulu ezindaweni ezinzima ngenxa yokungavikeleki kwayo ekusweleni umoya-mpilo kanye nokuphila isikhathi eside.
  • Amagesi Anobuthi (isb., H₂S): Ngokuyinhloko kusetshenziswa izinzwa ze-Electrochemical.
• Isitifiketi Esivikela Ukuqhuma: Imishini eSaudi Arabia ngokuvamile idinga ukuhlangabezana nezindinganiso zomhlaba wonke (njenge-ATEX, i-IECEx) kanye nesitifiketi sendawo. Izinhlobo zokuvikela ezivamile zifaka:
  • I-Ex d [Ayishisi]: I-enclosure ingamelana nokuqhuma kwangaphakathi ngaphandle komonakalo futhi ivimbele ukudluliselwa kwelangabi emoyeni wangaphandle.
  • I-Ex e [Ukuphepha Okukhulisiwe]: Kusetshenziswa izinyathelo ezengeziwe ukuvimbela ukuthi kungenzeka ukuthi kube khona ama-arcs, izinhlansi, noma amazinga okushisa aphezulu.
  • I-Ex i [Ukuphepha Kwangaphakathi]: Ukuphepha kuqinisekiswa ngokunciphisa amandla kagesi esiketheni. Lokhu kungenye yezinga eliphezulu lokuvikela, elivame ukusetshenziselwa izinzwa ezidinga ukulungiswa okubukhoma ensimini.

4. Ukuhlanganiswa Kwesistimu kanye Nokusetshenziswa Kwedatha:
Lezi zinzwa ezingaqhumi azisebenzi zodwa kodwa zixhunywe kuhlelo lokulawula ukutholwa kwegesi olusebenza emshinini wonke.

• I-Alarm Yesikhathi Sangempela: Uma inzwa ithola ukugcwala kwegesi kufinyelela ezingeni le-alamu esethiwe, ibangela ama-alamu azwakalayo nabonakalayo egumbini lokulawula eliphakathi, ikhomba indawo yokuvuza.
• Ukuvala/Ukulawula Okuzenzakalelayo: Uhlelo lungaqala ngokuzenzakalelayo izinqubo eziphuthumayo, njenge:
• Ukuvula izinhlelo zokungenisa umoya endaweni evuzayo.
• • Ukuvala ngokuzenzakalelayo ama-Emergency Valve afanele.
  • Ukumisa amaphampu noma ama-compressor aseduze.
• Ukufakwa Kwedatha Nokuhlaziya: Yonke idatha ifakwa futhi ihlaziywe ukuze kulungiswe kusengaphambili (isb., ukuhlonza imishini enokuvuza okuncane okuvamile), ukwenza ngcono imizila yokuqapha, kanye nokwenza ukuhlolwa kokuphepha.

Izinselele kanye Nezindlela Zesikhathi Esizayo

1. Ukuqina Kwemvelo: Isimo sezulu esibi kakhulu saseSaudi Arabia (izinga lokushisa eliphezulu, isihlabathi, ukugqwala kosawoti) sivivinya kakhulu izinto zokwakha, ukusebenza kokuvala, kanye nokuqina kwezingxenye ze-elekthronikhi. Imishini idinga izinga eliphezulu lokuvikelwa kokungena (IP).
2. Ukunciphisa Izindleko Zobunikazi: Lokhu kufaka phakathi izindleko zokulinganisa, ukulungisa, kanye nokushintsha izinzwa. Umkhuba wesikhathi esizayo ubheke ubuchwepheshe obuzinzile nobuhlala isikhathi eside (njenge-IR) kanye nezinzwa ezihlakaniphile ezinamakhono okuzihlola angabika amaphutha noma ukuwohloka.
3. Ukuhlakanipha Nokulungiswa Okubikezelayo: Kuhlanganiswe nobuchwepheshe be-IoT, izinzwa zegesi ezingaqhumi ziba yingxenye ye-Industry 4.0. Ngokuhlaziya izitayela zedatha, uhlelo lungaxwayisa ngokwehluleka kwemishini okungenzeka.ngaphambiUkugcwala kwegesi kufinyelela emazingeni ayingozi, kusuka ekusabeleni okusebenzayo kuya ekuvimbeleni okusebenzayo.
4. Izinzwa Ezingaqhumi Ezingenantambo: Ezinguqukweni zezitshalo noma ezindaweni lapho izintambo zinzima khona, ukusetshenziswa kwezinzwa zegesi ezingenantambo eziqinisekisiwe sekuba yisisombululo esengeziwe esiguquguqukayo nesisebenzayo.
