Pfupiso yePurojekiti

Chirongwa ichi inzvimbo yeLNG yekugadzirisa gasi iri munzvimbo yemaindasitiri muNigeria. Basa rayo guru rinoshandisa sisitimu yemvura inodziya. Inoshanda senzvimbo yakakosha yekushandura simba pakati pekuchengetera LNG nemapaipi emushandisi ari pasi pemvura, inoshandura gasi rechisikigo recryogenic liquid kuita mafuta egasi anodziya mumhepo kuburikidza nemaitiro ekuchinjana kupisa akasimba, ichipa mafuta akachena anoramba aripo uye akavimbika ekugadzira maindasitiri emuno.

Zvimiro zveChigadzirwa Chikuru & Zvehunyanzvi

1. Sisitimu Yekugezera Mvura Inoshanda Nesimba Rakakura

   Pakati pechiteshi pane ma "vaporizers" akawanda, akaenzana, achishandisa sisitimu yemvura yakavharwa senzira yekudziyisa. Sisitimu iyi inopa mabhenefiti akasiyana esimba rekudziyisa rinogadziriswa uye tembiricha yegesi inobuda. Haikanganisike nekuchinja-chinja kwekunze kwekunze uye hunyoro, ichichengetedza kugona kwakasimba kwekufema kwemhepo pasi pemamiriro ekunze chero api zvawo. Izvi zvinoita kuti ive yakakodzera zvakanyanya kune vashandisi vemaindasitiri vane zvinodiwa zvakanyanya zvekumanikidzwa kwemafuta netembiricha.

2. Kudzora Kupisa Kwakabatana & Kudzora Kupisa Kwakangwara

   Sisitimu iyi inobatanidza mabhoyira emvura inopisa anoshanda nesimba uye anoshandiswa negasi senzvimbo huru yekupisa, pamwe chete nema "heat exchangers" uye "circulating pombi sets". Sisitimu yakangwara yePID yekudzora tembiricha inodzora tembiricha yemvura yekugezera, ichivimbisa kudzora kwakarurama tembiricha yemhepo inobuda mu "vaporizer" (inowanzo gadzikana mukati me ±2°C). Izvi zvinovimbisa kushanda kwakachengeteka uye kwakasimba kwemapaipi nemidziyo iri pasi pemvura.

3. Kugadziriswa kwekuchengetedzwa kweMatanho Akawanda & Dhizaini yeEmergency

   Dhizaini yacho inosanganisira dual-loop heat source redundancy (main boiler + standby boiler) uye emergency power backup (yezvinhu zvakakosha uye ma control circuits). Izvi zvinoita kuti system ikwanise kuchengetedza kushanda kwakachengeteka kana kudzima zvakarongeka kana paine grid changes kana primary heat source ikakundikana. System iyi ine ma multi-level safety interlocks akavakirwa mukati ekumanikidza, tembiricha, uye level, akabatanidzwa ne combustible gas detection uye Emergency Shutdown (ESD) systems.

4. Dhizaini Yakagadzirirwa Mamiriro Egridi Asina Kugadzikana

   Kupindura kusagadzikana kwegrid yemuno, michina yese yakakosha inotenderera (semuenzaniso, pombi dzemvura dzinotenderera) inoshandisa tekinoroji yeVariable Frequency Drive (VFD), ichipa kugona kutanga zvinyoro nyoro uye kugadzirisa simba kuti ideredze kukanganiswa kwegrid. Sisitimu yekudzora iyi yakachengetedzwa neUninterruptible Power Supplies (UPS), ichivimbisa kugara ichitarisa kuchengetedzeka uye kudzora mashandiro panguva yekudzima kwemagetsi.

Rutsigiro rwehunyanzvi hwemunharaunda uye basa

Chirongwa ichi chakatarisana nekupihwa kwechikamu chikuru chekugadzirisa kupiswa kwemvura nemidziyo, kutarisa kuiswa, kupihwa basa, uye kudzidziswa kwehunyanzvi. Takapa kudzidziswa kwakakosha kune timu yekushanda yemuno yakagadzirirwa sisitimu iyi uye takagadzira nzira yekutsigira kwenguva refu inosanganisira rubatsiro rwehunyanzvi hwekure uye zvinhu zvemuno. Izvi zvinovimbisa kushanda kwenzvimbo iyi uye kuvimbika kwayo mukati menguva yayo yekushanda. Kupedzwa kwechiteshi ichi kunopa Nigeria nedzimwe nzvimbo zvivakwa zvemagetsi zvisina kugadzikana asi kudiwa kukuru kwekugadzikana kwegesi nemhinduro yeLNG yekugadzirisa gasi yakura, inoshanda zvakavimbika isingabatanidzwi nematambudziko ekunze.
