Mashandisirwo Emasensa Egasi Emaindasitiri muSaudi Arabia

Saudi Arabia, iyo ine simba guru pasi rose uye hupfumi huri kuchinja zviri pamutemo pasi pechirongwa chayo che "Vision 2030", inonyanya kusimbisa kuchengetedzeka, kushanda zvakanaka, uye kuchengetedzwa kwezvakatipoteredza mukati mezvikamu zvayo zvemaindasitiri. Mumamiriro ezvinhu aya, masensa egasi anoshanda setekinoroji yakakosha yekutarisa nharaunda, kuvimbisa kuchengetedzeka, uye kudzora maitiro. Gwaro iri rinopa ongororo yakadzama yezviitiko zvekushandiswa uye mamiriro chaiwo emasensa egasi mumaindasitiri akakosha muSaudi Arabia.

I. Zvinhu Zvikuru Zvinoita Kuti Ushandise

1. Kuchengetedzwa Kutanga: Maindasitiri makuru emafuta, gasi, uye petrochemical muSaudi Arabia anotarisira huwandu hwakawanda hwemagasi anobvira moto, anoputika, uye ane chepfu. Kubuda kwegasi ndicho chinhu chikuru chinokonzera moto, kuputika, uye chepfu yevashandi. Kutarisa gasi panguva chaiyo uye nemazvo inzira yakakosha yekudzivirira njodzi.
2. Kutevedzera Mitemo Yezvakatipoteredza: Nekuenderera mberi kwekutarisa kwepasi rose pakuchengetedza nharaunda, Bazi rezvezvakatipoteredza, Mvura nekurima reSaudi (MEWA) rakaisa mitemo yakasimba yekuburitsa utsi. Zvinonzwa gasi zvishandiso zvakakosha pakutarisa magasi egreenhouse (semuenzaniso, CH₄), kusvibisa kwechepfu (semuenzaniso, SO₂, NOx), uye Volatile Organic Compounds (VOCs) kuti ive nechokwadi chekutevedzera mitemo.
3. Kugadzirisa Maitiro & Kudzivirirwa Kwezvinhu: Mumabasa emaindasitiri, kuwanda kwemagasi chaiwo kunokanganisa zvakananga kushanda zvakanaka uye kunaka kwechigadzirwa. Uyezve, magasi anoparadza akadai seHydrogen Sulfide (H₂S) anogona kukonzera kukuvara kwakanyanya kumapaipi nemidziyo. Kutarisa magasi aya kunovandudza kugadzirwa kwezvinhu, kuwedzera hupenyu hwezvinhu, uye kunoderedza mari yekugadzirisa.
4. Hutano Hwebasa: Munzvimbo dzakamanikana (semuenzaniso, matangi ekuboorera, matangi ekuchengetera zvinhu, nzvimbo dzinoshandiswa mvura yakasviba), kushomeka kweokisijeni kana kuunganidzwa kwemagasi ane njodzi kuvashandi. Masensa egasi anotakurika uye akasimba anopa yambiro yakakosha pakutanga.

II. Maitiro Akakosha Ekushandisa Maindasitiri & Zvidzidzo Zvenyaya

1. Indasitiri yeOiri neGasi

Iyi ndiyo nzvimbo yakakura uye inoda mari yakawanda yekushandisa masensa egasi muSaudi Arabia.

• Kutsvaga & Kugadzira Kwemvura:
  • Chiitiko: Michina yekuboorera, nzvimbo dzekuchera matsime, nzvimbo dzekuunganidzira matombo.
  • Magasi Anotariswa: Magasi anobvira (LEL – Muganho Wekuputika Wakaderera), Hydrogen Sulfide (H₂S), Carbon Monoxide (CO), Sulfur Dioxide (SO₂), Oxygen (O₂).
  • Chidzidzo Chemuenzaniso: Pamunda wemafuta weGhawar muEastern Province, zviuru zvezvishandiso zvegasi zvakagadziriswa zvinoiswa panzvimbo dzinopinda mafuta uye panosangana mapaipi, zvichigadzira network yekutarisa yakawanda. Kana kudonha kwemethane (CH₄) kukaonekwa pamusoro pemuganho wakatarwa (kazhinji 20-25% LEL), sisitimu iyi inokonzeresa maalarm anonzwika uye anoonekwa, inoisa otomatiki sisitimu yeEmergency Shutdown (ESD) kuti iparadzanise kudonha kwemafuta, uye inotumira data kukamuri rekutonga repakati kuti rigadziriswe nekukurumidza. Kuongororwa kweH₂S ine chepfu yakawanda kunoda kunyatsorongeka (kazhinji pamazinga eppm) kuve nechokwadi chekuchengetedzwa kwevashandi.
• Kugadzirisa Pakati & Pasi:
  • Mamiriro ezvinhu: Nzvimbo dzekuchenesa, nzvimbo dzemafuta, mapaipi, nzvimbo dzematangi ekuchengetera zvinhu.
  • Magasi Anotariswa: Kuwedzera pane zvataurwa pamusoro apa, Volatile Organic Compounds (VOCs) (semuenzaniso, Benzene, Toluene), Ammonia (NH₃), uye Chlorine (Cl₂) zvinotariswa.
  • Chidzidzo Chemuenzaniso: Munzvimbo hombe dzemafuta muJubail kana kuti Yanbu, masisitimu ekutarisa gasi ane matanho akawanda akaiswa pamadziro emagetsi anopwanya matangi uye anobvisa mvura. Semuenzaniso, mumatangi, masensa eOpen-Path Infrared (IR) anogadzira "fenzi yemagetsi" isingaoneki kuti ione kupararira kweVOC fugitive emissions, kudzivirira mhepo dzinoputika uye kuona kuti zvakatipoteredza zvinotevedzera mitemo. Pamuganhu wefekitori, vaongorori veSO₂ vanopa data remhepo inobuda nguva dzose kuti vavimbise kutevedzera mitemo yeMEWA.

2. Zvishandiso & Kugadzira Magetsi

• Mamiriro ezvinhu: Zvivakwa zvemagetsi (kunyanya nzvimbo dzemagetsi egasi), zviteshi zvemagetsi, nzvimbo dzekuchenesa mvura yakasviba.
• Magasi Anotariswa: Magasi anobvira (CH₄), Hydrogen (H₂) (yekutonhodza jenareta), Ozone (O₃), Chlorine (Cl₂) (yekurapa mvura), Hydrogen Sulfide (H₂S) (inogadzirwa mumapombi etsvina uye maitiro ekurapa).
• Chidzidzo Chemuenzaniso: Pachiteshi chikuru chemagetsi muRiyadh, masensa e catalytic bead kana IR anoshandiswa zvakanyanya kutarisa kubuda kwemethane mumakamuri eturbine uye munzvimbo dzinodzora gasi rechisikigo. Panguva iyi, mumatunnel etambo nepasi pevhu, ma detector akasimba anodzivirira kuputika kubva kumagasi anobvira anokonzerwa nekupisa zvakanyanya kwemidziyo yemagetsi. Pafekitari yemvura yakasviba iri pedyo, vashandi vanofanirwa kushandisa ma detector anotakurika ane gasi rakawanda kuti vatarise huwandu hwakachengeteka hweO₂, LEL, H₂S, uye CO vasati vapinda munzvimbo dzakamanikana dzakadai sematangi e sedimentation, vachinyatsotevedzera maitiro ekupinda.

3. Zvivakwa & Zvivakwa zveMaguta

• Mamiriro ezvinhu: Magaraji ekupaka mota, matunnel, nzvimbo dzekutenga, marabhoritari ezvipatara.
• Magasi Anotariswa: Carbon Monoxide (CO), Nitrogen Oxides (NOx) (zvikurukuru inobva muutsi hwemotokari).
• Chidzidzo Chemuenzaniso: Munzvimbo huru dzekupaka mota pasi pevhu muRiyadh kana Jeddah, masisitimu ekufema anowanzo vharwa nemasensa eCO. Kana huwandu hwemhepo hukakwira kusvika padanho rakatarwa (semuenzaniso, 50 ppm), masensa anongoerekana aita kuti mafeni emagetsi apinde mumhepo itsva kusvika padanho rakachengeteka, zvichidzivirira hutano hwevatengi nevashandi.

4. Migodhi & Kugadzira Simbi

• Chiitiko: Migodhi yephosphate, migodhi yegoridhe, michina yekunyungudutsa.
• Magasi Anotariswa: Kunze kwemagasi ane chepfu uye anobvira, magasi anoenderana nemaitiro akaita sePhosphine (PH₃) neHydrogen Cyanide (HCN) anoda kutariswa.
• Chidzidzo Chemuenzaniso: Kuguta reWa'ad Al-Shamal phosphate, nzira yekugadzira fetereza inogona kugadzira PH₃. Masensa ePH₃ emagetsi kana semiconductor akatsaurirwa akaiswa munzvimbo dzekugadzirisa uye munzvimbo dzekuchengetera zvinhu anopa mukana wekuona kudonha kwemvura nekukurumidza, zvichidzivirira kusangana nevashandi.

III. Mafambiro eTekinoroji uye Maonero Eramangwana

Mashandisirwo ekuona gasi muSaudi Arabia ari kufambira mberi akananga kuhungwaru uye kubatanidzwa kukuru:

1. IoT & Digitalization: Masensa ari kuchinja kubva kuma alarm units ega ega kuenda kuma networked data nodes. Uchishandisa matekinoroji asina waya akadai seLoRaWAN ne4G/5G, data rinotumirwa panguva chaiyo kuma cloud platforms ekutarisa kure, big data analytics, uye kugadzirisa zvinofanotaurwa.
2. Kuongorora UAV & Robotic: Munzvimbo dzakakura kana dzine njodzi (semuenzaniso, mapaipi ari kure, nzvimbo dzakareba), madrone ane masensa akadai se laser methane detectors anoita ongororo dzinoshanda uye dzakachengeteka, achikurumidza kuona nzvimbo dzinodonhedza mvura.
3. Matekinoroji Ekuona Zvinhu Akanyanya Kubudirira: Matekinoroji akanyatsogadzirwa uye akasarudzwa zvakanaka akadai seTunable Diode Laser Absorption Spectroscopy (TDLAS) uye Photoionization Detectors (PID yeVOCs) ari kushandiswa zvakanyanya kuti asangane nezvinodiwa zvakasimba zvekuchengetedza nharaunda.
4. Kubatanidzwa kweAI: Maalgorithms eAI anogona kuongorora mapatani edata re sensor kuti asiyanise njodzi chaiyo kubva kumaalarm enhema (semuenzaniso, maalarm anokonzerwa nedhiziri) uye kufanotaura kutadza kwemidziyo kana mafambiro ekubuda kwemvura.

Mhedziso

Pasi pe "Vision 2030" yeSaudi Arabia, iyo inosimudzira kusiyanisa hupfumi uye kuvandudzwa kwemaindasitiri, masensa egasi ave varindi vanokosha pakuchengetedzeka kwemaindasitiri ayo makuru uye kubudirira kwebudiriro yezvirimwa uye inochengetedza nharaunda. Kubva kuminda yakakura yemafuta kusvika kumaguta emazuva ano, varindi ava vasingaoneki vanoshanda maawa makumi maviri nemana pazuva, vachichengetedza vashandi, vachichengetedza nharaunda, uye vachivandudza kugadzirwa. Vanoumba hwaro hwakakosha hweramangwana reindasitiri yeSaudi, uye mashandisirwo avo pasina mubvunzo acharamba achikura zvakadzama uye zvakanyanya sezvo tekinoroji ichifambira mberi.

Seti yakakwana yemaseva nesoftware isina waya module, inotsigira RS485 GPRS /4g/WIFI/LORA/LORAWAN

Kuti uwane mamwe masensa egasi ruzivo,
