Gasi rechisikigo rakanyungudika (LNG) igasi rechisikigo, rinonyanya kushandiswa semethane, rakatonhodzwa kuita semvura kuti rive nyore uye rakachengeteka pakuchengetwa nekutakurwa. Rinotora chikamu chimwe muzvitanhatu chehuwandu hwegasi rechisikigo kana riri mugasi.
A chirimwa chose chemvura inonyungudutsa LNG inosanganisira masisitimu matatu: sisitimu yekushanda, sisitimu yekudzora zvishandiso uye sisitimu yemagetsi. Zvichienderana nemhepo dzakasiyana, inogona kuchinjwa.
Maitiro ekugadzira cryogenic LNG Plant anosanganisira:
- Kusefa kwegasi rekudyisa, kupatsanurwa, mutemo wekumanikidzwa uye chiyero chekuyera;
- Chigadziko chekumanikidza gasi rinodyisa
- Chikamu chekurapa chisati chatanga (kusanganisira chikamu chekubvisa asidhi mugasi, kushaya mvura mumuviri uye kubvisa mahydrocarbon akawanda, kubvisa mercury neguruva);
- Chikamu cheMR proportioning uye chikamu cheMR compression cycle;
- Chikamu cheLNG liquefaction (kusanganisira chikamu che denitrification);
Pano, tinokuzivisai nezvehurongwa hwekudzora midziyo yemuchina weLNG.
Kuti zvinyatso tarisa maitiro ekugadzira michina yese, kuve nechokwadi chekuti inoshanda zvakanaka, uye kuita kuti mashandiro aro ashande zvakanaka, sisitimu yekudzora michina yesystem iyi inosanganisira: sisitimu yekudzora yakagoverwa (DCS), sisitimu yekuchengetedza michina (SIS), kuona moto negasi rinobvira uye sisitimu yekunyevera (GDS), sisitimu yekutarisa mavhidhiyo (CCTV), uye zvishandiso zvine hungwaru (flowmeters, analyzers, tembiricha, kumanikidzwa, kuyerera) zvinosangana nezvinodiwa nemaitiro acho, nezvimwewo, zvichipa mabasa ekugadzirisa, kuita kuti zvinhu zvishande, uye kutarisa, kusanganisira kuwana data reprocess, kudzora kwakavharwa, kutarisa mamiriro ekushanda kwemidziyo, cheni yealamu uye sevhisi, kugadzirisa nekuratidza data renguva chaiyo, sevhisi yefashoni, kuratidzwa kwemifananidzo, sevhisi yerekodhi yekushanda nemamwe mabasa. Kana paine emergency mumudziyo wekugadzira, kana kuti kana sisitimu yeGDS yatumira chiratidzo chealamu, SIS ichatumira chiratidzo chekudzivirira chekudzivirira michina iri panzvimbo, uye sisitimu yeGDS ichazivisa dhipatimendi remoto remunharaunda panguva imwe chete.
Zvishandiso zvese zvekudzora zvinofanirwa kuiswa munzvimbo ine njodzi zvinosangana nezvinodiwa zvenzvimbo ine njodzi uye kuchengetedzeka kwakazara, uye dhizaini nesarudzo zvinotevedzera mitemo yenyika yakakodzera.
Pamusoro pezvo, sisitimu yekudzora michina yakakwana munzvimbo yeprocess unit inodzorwa nePLC yakazvimiririra, uye masaini ayo akakosha anotumirwa kuDCS iri mukamuri rekudzora repakati kuti iratidzwe kuburikidza nekutaurirana pakati pemasisitimu, uye yakabatana nesisitimu yekuchengetedza zvishandiso (SIS) newaya dzakaoma.
Sisitimu yekudzora zviridzwa (chikamu chekugadzirisa) ine zvikamu zvinotevera:
★ Sisitimu Yekudzora Yakaparadzirwa (DCS) : DCS ndiyo musimboti uye pakati pehurongwa hwekudzora zvishandiso, iyo inopa kuratidzwa, mashandiro uye kutonga kwese ma process parameters nema alarm, uye ine kugona kutaurirana nedzimwe system.
★ Sisitimu Yekuchengetedza Zvishandiso (SIS) : Icho chikamu chekuchengetedzwa kwesystem, chinonyanya kushandiswa pakuchengetedza zvishandiso mumamiriro ezvinhu enjodzi, zvichienderana nehurongwa hwekupaka hwakatarwa, husingabatanidzwi neDCS muchimiro, uye hwakakwirira padanho rekuchengetedza kupfuura DCS.
★ Simba risingachinjiki (UPS) : Sechikamu chekuvimbika kwesystem, inogona kupa simba rekushanda kwenguva yakati kana magetsi akangoerekana atadza kushanda kuitira kuti process process ivharwe uye kurapwa nekukurumidza.
★ Chishandiso chekuyera maitiro : chikamu chikuru chekugadzirisa masisitimu, icho chinoumbwa nezvishandiso zvekuyera zvakasiyana-siyana nemasensa, ayo kururama kwawo uye kunyatsojeka zvinokanganisa zvakananga kutonga kwekugadzirisa masisitimu.
★ Vharuvhu yekudzora : chikamu chekugadzirisa nekuita ma process parameters.
★ Muongorori wepamhepo : Inonyanya kuumbwa nezvimwe zvishandiso zvekuongorora zvikamu, izvo zvinowedzera kune zvishandiso zvekuyera uye zvinopa hwaro hwekushanda kwekudzora maitiro.
