Ulwakhiwo lwemizi-mveliso yaseSaudi Arabia lulawulwa yioyile, igesi yendalo, iikhemikhali zepetroli, iikhemikhali kunye nemigodi. Ezi mizi-mveliso zibeka umngcipheko omkhulu wokuvuza kwegesi enokutsha, eqhumayo, neyityhefu. Ke ngoko, izinzwa zegesi ezithintela ukuqhuma ziphakathi kwezona zinto zibalulekileyo kumgca ongaphambili kwiinkqubo zayo zokhuseleko lwemizi-mveliso.
Imvelaphi yeTyala kunye neemfuno eziphambili
- Iimpawu zoshishino: Lonke uthotho lweoyile negesi eSaudi Arabia—ukusuka ekubholeni nasekukhupheni imveliso ukuya ekuthuthweni nasekucocweni kwemveliso ephakathi, kunye nemveliso yepetrochemical esezantsi—lubandakanya iihydrocarbons (i-methane, ipropane, ii-VOCs, njl.njl.) kunye neegesi ezinobuthi (iHydrogen Sulfide H₂S, iCarbon Monoxide CO, njl.njl.).
- Iimfuneko zeNdalo: Ezi ndawo zihlala zihlelwa njengeendawo eziyingozi (eziqhumayo). Nasiphi na isixhobo sombane esisetyenziswayo kufuneka sibe nesatifikethi esingenakuqhuma ukuthintela isixhobo ekubeni ngumthombo womlilo.
- Abaqhubi Bolawulo: Imigangatho yokhuseleko engqongqo evela kwi-Saudi Arabian Standards Organisation kunye neenkampani ezinkulu zelizwe ezifana neSaudi Aramco (umz., imigangatho ye-SAES ye-Aramco) iyalela ukufakwa kweenkqubo zokufumanisa igesi eziqinisekisiweyo kuzo zonke iindawo ezinobungozi.
Imeko Eqhelekileyo: Inkqubo Yokufumanisa Igesi Edibeneyo kwiJazan Refinery yaseSaudi Aramco
1. Isishwankathelo seProjekthi:
- Indawo: Isixeko sezoQoqosho saseJazan, eSaudi Arabia.
- Indawo: IJazan Refinery yindawo enkulu edibeneyo yokucocwa, iikhemikhali zepetrochemicals, kunye nokuveliswa kombane.
- Umngeni: Esi sakhiwo sicubungula inani elikhulu leoyile ekrwada enesulfure eninzi, nto leyo ethetha umngcipheko omkhulu wokuvuza kwe-H₂S. Ukongeza, sonke isityalo sineegesi ezininzi ezinokutsha. Indawo engqonge unxweme enobushushu obuphezulu, ukufuma okuphezulu, kunye netyuwa ephezulu ibangela imingeni enzima ekuqineni kwezixhobo.
2. Imizekelo yokusetyenziswa kweeSensors zeGesi ezingaQhubiyo:
Kwindawo enkulu kangaka, izixhobo zokuvavanya igesi ezithintela ukuqhuma zifakwa kwiindawo ezibalulekileyo ezingamakhulu:
- Iimpompo kunye neeCompressor Seals: Ezi zixhobo ezijikelezayo ziindawo eziqhelekileyo zokuvuza. Iisensa zeCatalytic Bead okanye zeInfrared ezithintela ukuqhuma zifakelwe ukujonga iigesi ezitshayo.
- Indawo yokugcina iTanki (kufutshane neengxobo zokungenisa umoya kunye neengalo zokulayisha): Umphunga unokukhululwa ngexesha lokudluliselwa kwemveliso okanye "ukuphefumla" ngenxa yotshintsho lobushushu. Iisensors zibonelela ngovavanyo oluqhubekayo apha.
- Iindawo zeCandelo leNkqubo (umz., ii-reactors, iikholamu zokuqhekezwa): Izixhobo zokubona igesi ezizinzileyo zifakelwe kwiiflanges kunye noqhagamshelo lweevalvu apho i-H₂S kunye neegesi ezinokutsha zinokubakho khona. Ezi sensors zihlala zinesatifikethi se-Intrinsic Safety (Ex i), oko kuthetha ukuba azinakukhupha amandla aneleyo okubangela ukutsha, nokuba ziyasilela ngelixa zisebenza.
- Iinkqubo zoGutyulo kunye nokuHanjiswa kwamanzi: Ezi ndawo zixineneyo zinokuqokelela iigesi ezinokutsha (umz., i-methane). Iisensa zohlobo lokusasazwa okanye ezixhaswa yiPump-assist explosion-proof sensors zisetyenziselwa ukujonga.
- Umoya Ongena Kwigumbi Lolawulo Neendawo Zokuhlala: Kufakelwa ii-sensors kwiindawo zokungenisa umoya kwezi zakhiwo ukuthintela ukuba iigesi ezinobuthi okanye ezivuthayo zingatsalwa ngaphakathi, ukuqinisekisa ukhuseleko lwabasebenzi.
3. Ubuchwepheshe beSensor kunye neendidi ezichasene nokuqhuma:
- Imigaqo yeTekhnoloji:
- Iigesi Ezivuthayo: Ngokuyintloko kusetyenziswa ubuchwepheshe beCatalytic Bead kunye neNon-Dispersive Infrared. I-NDIR ithandwa kakhulu kwiindawo ezinzima ngenxa yokungakhuseleki kwayo kwi-oxygen engaphantsi kwayo kwaye ihlala ixesha elide.
- Iigesi Ezinobuthi (umz., H₂S): Ngokuyintloko kusetyenziswa ii-Electrochemical sensors.
- Isiqinisekiso Esingaqhumiyo: Izixhobo eSaudi Arabia zihlala zifuna ukuhlangabezana nemigangatho yamazwe ngamazwe (njenge-ATEX, i-IECEx) kunye nesiqinisekiso sendawo. Iindidi zokhuseleko eziqhelekileyo ziquka:
- I-Ex d [Ayitshisi]: Isiciko sinokumelana nokuqhuma kwangaphakathi ngaphandle komonakalo kwaye sithintele ukudluliselwa komlilo emoyeni wangaphandle.
- I-Ex e [Ukhuseleko Olunyusiweyo]: Kusetyenziswa amanyathelo ongezelelweyo ukuthintela ukuba kungenzeka ukuba kubekho ii-arcs, iintlantsi, okanye amaqondo obushushu agqithisileyo.
- I-Ex i [Ukhuseleko lwangaphakathi]: Ukhuseleko luqinisekiswa ngokunciphisa amandla ombane kwisekethe. Eli lelinye lamanqanaba aphezulu okhuseleko, adla ngokusetyenziswa kwiisensa ezifuna ukulungiswa bukhoma ebaleni.
4. Ukuhlanganiswa kweNkqubo kunye nokusetyenziswa kweDatha:
Ezi sensors zithintela ukuqhuma azisebenzi zodwa kodwa ziqhagamshelwe kwiNkqubo yoLawulo lokuFumanisa iGesi kwisikhululo sonke.
- Isilumkiso seXesha langempela: Xa inzwa ibona uxinano lwegesi ifikelela kwinqanaba lesilumkiso elimiselweyo, ibangela ii-alamu ezivakalayo nezibonakalayo kwigumbi lolawulo eliphakathi, ikhomba indawo yokuvuza.
- Ukucima/ukulawula ngokuzenzekelayo: Inkqubo inokuqalisa ngokuzenzekelayo iinkqubo ezingxamisekileyo, ezifana nezi:
- Ukuvuselela iinkqubo zokungenisa umoya kwindawo evuzayo.
-
- Ukuvala ngokuzenzekelayo iiValve zokuvala ezingxamisekileyo ezifanelekileyo.
- Ukumisa iimpompo okanye iicompressor ezikufutshane.
- Ukugcinwa kwedatha kunye noHlalutyo: Yonke idatha igcinwa kwaye ihlalutywe ukuze kugcinwe kwangaphambili (umz., ukuchonga izixhobo ezinokuvuza okuncinci rhoqo), ukuphucula iindlela zokulinda, kunye nokwenza uhlolo lokhuseleko.
Imingeni kunye neendlela zexesha elizayo
- Ukuqina Kwendalo: Imozulu egqithisileyo yaseSaudi Arabia (ubushushu obuphezulu, isanti, ukugqwala kwetyuwa) ivavanya kakhulu izixhobo zokuhlala, ukusebenza kokutywina, kunye nozinzo lwezixhobo ze-elektroniki. Izixhobo zifuna uVavanyo oluphezulu loKhuseleko lokuNgena (IP).
- Ukunciphisa Iindleko Ezipheleleyo Zobunini: Oku kuquka iindleko zokulinganisa, ukugcinwa, kunye nokutshintshwa kwesensa. Ikamva lijonge kubuchwepheshe obuzinzileyo nobuhlala ixesha elide (njenge-IR) kunye neesensa ezikrelekrele ezinezakhono zokuzixilonga ezinokuxela iimpazamo okanye ukonakala.
- Ubuchule kunye noLondolozo oluQikelelweyo: Idityaniswe netekhnoloji ye-IoT, izinzwa zegesi ezingakwaziyo ukuqhuma ziba yinxalenye yeShishini 4.0. Ngokuhlalutya iindlela zedatha, inkqubo inokulumkisa ngokusilela kwezixhobo.ngaphambiUbuninzi begesi bufikelela kumanqanaba ayingozi, butshintsha ukusuka ekuphenduleni okukhawulezayo ukuya ekuthinteleni okusebenzayo.
- Izinzwa Ezingaqhumiyo Ezingenazingcingo: Kwiinguqulelo zezityalo okanye kwiindawo apho iingcingo zinzima khona, ukusetyenziswa kwezinzwa zegesi ezingenazingcingo eziqinisekisiweyo kuba sisisombululo esongezelelweyo nesiguquguqukayo nesisebenzayo.
- Iseti epheleleyo yeeseva kunye nemodyuli engenazingcingo yesoftware, ixhasa i-RS485 GPRS /4g/WIFI/LORA/LORAWAN
