Kushandiswa kweMasensa eGasi Asingaputike muBazi reMaindasitiri reSaudi Arabia

Maumbirwo emaindasitiri eSaudi Arabia anotongwa neoiri, gasi rechisikigo, makemikari epetrochemicals, makemikari, uye migodhi. Maindasitiri aya ane njodzi huru dzekubuda kwegasi rinobvira moto, rinoputika, uye rine chepfu. Saka, masensa egasi asingaputike ndeezvimwe zvezvinhu zvakakosha zvikuru muhurongwa hwayo hwekuchengetedza maindasitiri.

Nhoroondo yeNyaya uye Zvinodiwa Zvikuru

• Hunhu hweIndasitiri: Kutengeswa kwemafuta negasi muSaudi Arabia—kubva pakuchera nekuburitsa mafuta kusvika pakutakura nekunatsa mafuta pakati pemvura, uye kugadzirwa kwemafuta emumvura—kunosanganisira mahydrocarbon (methane, propane, VOCs, nezvimwewo) uye magasi ane chepfu (Hydrogen Sulfide H₂S, Carbon Monoxide CO, nezvimwewo).
• Zvinodiwa Pakuchengetedzwa Kwenharaunda: Nzvimbo idzi dzinowanzo rongwa seNzvimbo Dzine Ngozi (Dzinoputika). Chero michina yemagetsi inoshandiswa inofanira kunge iine chitupa chisingaputike kuti michina isave chinhu chinobatidza moto.
• Zvinotungamira Mutemo: Mitemo yakasimba yekuchengetedza kubva kuSaudi Arabian Standards Organisation pamwe nemakambani makuru enyika akaita seSaudi Aramco (semuenzaniso, mitemo yeSAES yeAramco) inorayira kuiswa kwemasisitimu ekuona gasi ane certification munzvimbo dzese dzine njodzi.

Nyaya Yakajairika: Sisitimu Yakabatanidzwa Yekuona Gasi paJazan Refinery yeSaudi Aramco

1. Pfupiso yePurojekiti:

• Nzvimbo: Jazan Economic City, Saudi Arabia.
• Nzvimbo: Jazan Refinery inzvimbo yakakura yakabatana yekunatsa, kugadzira petrochemicals, uye kugadzira magetsi.
• Dambudziko: Nzvimbo iyi inogadzirisa huwandu hwakawanda hwemafuta asina kucheneswa ane sarufa yakawanda, zvichireva njodzi huru yekubuda kwemvura muH₂S. Pamusoro pezvo, nzvimbo yese ine mhepo yakawanda ine gasi rinobvira moto. Nzvimbo yegungwa ine tembiricha yakakwira, hunyoro hwakawandisa, uye munyu wakawanda inokonzera matambudziko makuru ekugara kwenguva refu kwemidziyo.

2. Maitiro ekushandisa Masensa eGasi Asingaputike:
Munzvimbo yakakura kudaro, masensa egasi asingaputike anoiswa munzvimbo dzakawanda dzinokosha:

• Zvisimbiso zvePombi neCompressor: Midziyo iyi inotenderera inzvimbo dzinowanikwa mvura yakawanda. Masensa eCatalytic Bead kana Infrared asingaputike akaiswa kuti aongorore magasi anobvira.
• Nzvimbo yeTangi Rekuchengetera Zvinhu (pedyo nemaziburi emhepo nemaoko ekurodha zvinhu): Utsi hunogona kuburitswa panguva yekutamiswa kwechigadzirwa kana kubva "mukufema" nekuda kwekuchinja kwetembiricha. Masensa anopa nguva dzose kutarisa pano.
• Nzvimbo dzeMagadzirirwo eMagetsi (semuenzaniso, ma reactor, fractionation columns): Zvishandiso zvegasi zvisina kugadziriswa zvinoiswa pamaflanges nekubatanidza mavharuvhu uko H₂S nemagasi anobvira zvinogona kunge zviripo. Ma sensor aya anowanzo kuve neIntrinsic Safety (Ex i) certification, zvichireva kuti haagone kuburitsa simba rakakwana kuti akonzere kupisa, kunyangwe akakundikana achishandiswa.
• Masisitimu etsvina nekubvisa mvura: Nzvimbo idzi dzakamanikana dzinogona kuungana magasi anobvira (semuenzaniso, methane). Masensa emhando yeDiffusion kana kuti Pomp-assisted explosion-proof sensors anoshandiswa pakuongorora.
• Mapindiro emhepo mudzimba dzekudzora nedzekuchengetedza: Masensa anoiswa panzvimbo dzinopinda mweya muzvivako izvi kudzivirira magasi ane chepfu kana anobvira kuti asapinzwe mukati, zvichiita kuti vashandi vagare vakachengeteka.

3. Tekinoroji yeSensor uye Mhando Dzinodzivirira Kuputika:

• Nheyo dzeTekinoroji:
  • Magasi Anobvira: Anonyanya kushandiswa matekinoroji eCatalytic Bead neNon-Dispersive Infrared. NDIR iri kuramba ichifarirwa munzvimbo dzakaoma nekuda kwekusadzivirirwa kwayo kumhepo inoshaya okisijeni uye kurarama kwenguva refu.
  • Magasi ane chepfu (semuenzaniso, H₂S): Kunyanya kushandisa masensa eElectrochemical.
• Chitupa Chisingaputike: Midziyo muSaudi Arabia inowanzo fanirwa kusangana nezvinodiwa pasi rose (seATEX, IECEx) uye chitupa chemuno. Mhando dzedziviriro dzakajairika dzinosanganisira:
  • Ex d [Inodzivirira Murazvo]: Chivharo ichi chinogona kutsungirira kuputika kwemukati pasina kukuvara uye kudzivirira kutapurirana kwemurazvo kuenda kumhepo yekunze.
  • Ex e [Kuchengetedzwa Kwakawedzerwa]: Mamwe matanho anoshandiswa kudzivirira mukana wekuti arcs, sparks, kana tembiricha yakawandisa zviitike.
  • Ex i [Kuchengetedzwa Kwemukati]: Kuchengetedzeka kunovimbiswa nekuderedza simba remagetsi mudunhu. Iyi ndeimwe yemazinga ekudzivirira akakwirira, anowanzo shandiswa kumasensa anoda kugadziriswa aripo mumunda.

4. Kubatanidzwa kweSisitimu uye Kushandiswa kweData:
Ma sensor aya asingaputike haashande ari ega asi akabatana neGas Detection Control System yemuchina wese.

• Alarm Yenguva Yechokwadi: Kana sensor ikaona huwandu hwegasi huchisvika padanho realarm rakagadzirirwa, inotanga maalarm anonzwika uye anoona mukamuri rekudzora riri pakati, zvichiratidza nzvimbo inodonhedza mvura.
• Kudzima/Kudzora otomatiki: Sisitimu iyi inogona kutanga otomatiki maitiro ekukurumidzira, akadai se:
• Kuvhura masisitimu ekufema munzvimbo inodonhedza mvura.
• • Kuvhara otomatiki mavharuvhu akakodzera eEmergency Shut-Down.
  • Kumisa mapombi kana macompressor ari pedyo.
• Kunyora nekuongorora Data: Data rese rinonyorwa uye rinoongororwa kuti rigadziriswe nekufanotaura (semuenzaniso, kuona michina ine maburi madiki anowanzobuda), kugadzirisa nzira dzekutarisa, uye kuita ongororo dzekuchengetedza.

Matambudziko uye Maitiro Eramangwana

1. Kugara Kwenguva Refu Kwezvakatipoteredza: Mamiriro ekunze akaipisisa muSaudi Arabia (kupisa kwakanyanya, jecha, ngura yemunyu) anoedza zvakanyanya zvinhu zvemumba, kushanda kwekuvhara, uye kugadzikana kwezvikamu zvemagetsi. Midziyo inoda Ingress Protection (IP) Rating yakakwira.
2. Kuderedza Mari Yese Yekuva Muridzi: Izvi zvinosanganisira mutengo wekugadzirisa, kugadzirisa, uye kutsiva masensa. Mufambiro weramangwana uri pakushandisa matekinoroji akasimba, anogara kwenguva refu (senge IR) uye masensa akangwara ane kugona kuzviongorora anogona kuzivisa zvikanganiso kana kuora.
3. Kugadzirisa Zvinhu Zvine Hungwaru uye Kufanotaura Kugadziriswa: Zvakabatana netekinoroji yeIoT, masensa egasi asingaputike ari kuva chikamu cheIndustry 4.0. Nekuongorora mafambiro edata, sisitimu inogona kunyevera nezvekutadza kwemidziyo.pamberikuwanda kwemagasi kunosvika padanho rine njodzi, kuchichinja kubva pakupindura kwegasi kuenda pakudzivirira kwegasi.
4. Masensa Asingaputike Newaya: Pakugadzirisa mafekitori kana nzvimbo dzine waya dzakaoma, kushandiswa kwemasensa egasi asina waya ane certification kuri kuva mhinduro yekuwedzera inochinjika uye inoshanda.
