Tsananguro yemaitiro eyuniti yega yega yeBOG reliquefying plant
BOG yetangi rekuchengetera LNG inopinda mubhokisi rinotonhorera mushure mekumanikidzwa uye kuyerwa, inotonhodzwa, inonyungudutswa, uye inotonhodzwa zvakanyanya mu plate-fin heat exchanger, uye inodzoserwa kutangi rekuchengetera LNG sechigadzirwa cheLNG mushure mekupwanyika.
Nzira huru ye tekinoroji yekushandisa mudziyo uyu ndeiyi:
Maitiro ekutonhodza mhepo nemhepo (MRC) anoshandiswa kunyungudutsa gasi rese reBOG rakacheneswa;
Iyi sisitimu yemaitiro inosanganisira:
Kuparadzanisa gasi rekusefa uye kudzvanywa kwechikamu chekumanikidza;
Sisitimu yekunyungudutsa mvura yeLNG;
Chikamu chekutonhodza chemufiriji chakasanganiswa;
1) Kupatsanura gasi rekudya uye chikamu chekumanikidza
1) Tsananguro yemaitiro
Gasi reBOG rinopinda mumhepo inodziya gasifier uye inodyisa gasi rinopisa, uye mushure mekudzvanywa, kupatsanurwa, uye kuyerwa, rinopinda muchikamu chemvura chinodzika.
Midziyo mikuru yekugadzira igesi inodziya nemhepo, chinoshandiswa kupisa negesi yekudyisa, chiyereso chekuyerera, chiyereso chekukwidza simba, chiyereso chekukwidza simba, nezvimwewo.
1) Tsananguro yemaitiro
Usati wapinda muchikamu chemvura inonyungudutsa, gasi rekuchenesa rinofanira kuongororwa kuti rive nechokwadi chekuti mvura, zvinhu zvinonhuhwirira uye mercury zvinosangana nezvinodiwa kuti zvipinde muchikamu ichi. chikamu chemvura inonyunguduka.
BOG yakacheneswa Gasi rinotanga rapinda mu liquefaction heat exchanger mu cold box, rotonhodzwa zvishoma nezvishoma ne refrigerant inodzoka ine tembiricha yakaderera, rozotonhodzwa zvakanyanya kusvika -162 °C , wobva wapinda muLNG separator kuti uwane zvigadzirwa zveLNG.
Midziyo mikuru ibhokisi rinotonhora, iro rinonyanya kusanganisira maplate heat exchangers, akasiyana-siyana ekuparadzanisa, nezvimwewo.
3) Chikamu chekudzvanya mufiriji chakasanganiswa uye chikamu chekuyera
1) Tsananguro yemaitiro
Musanganiswa wefiriji wemuchina uyu uchange uine mafiriji emethane, nitrogen uye hydrocarbon akacheneswa.
Kudzvanywa kwemufiriji kunosanganisira compressor yemufiriji inopisa uye compressor yemufiriji inopisa. Compressor yemufiriji inopisa inonyanya kupa kugona kwekutonhodza kwechikamu chinodziya zvakanyanya, uye compressor yemufiriji inopisa inonyanya kupa kugona kwekutonhodza kwechikamu chinodziya zvakanyanya.
Midziyo mikuru i refrigerant cycle compressor, refrigerant proportional tank, nezvimwewo.
2) Magadzirirwo edhizaini
Kukwanisa kunyungudutsa mvura: matani 224.7/zuva
Rudzi rweCompressor: Screw Compressor
Macompressor maviri (compressor imwe chete yerefrigerant inodziya zvakanyanya uye yakaderera)
Kumanikidzwa kwekusvuta 0.3MPa.G
Kupisa kwekusveta 40.0 ℃
Kumanikidzwa kweutsi 1.9MPa.G (zvichireva flange yekubuditsa yechinhu chinotonhorera chekupedzisira)
Tembiricha yekubuda kwemhepo 40 °C (achireva flange yekubuditsa yechinhu chinotonhorera chekupedzisira)
3) Rudzi rwekugadzirisa
50% ~ 110%.
4) Chigadziko chekupisa chebhokisi rinotonhora
Usati watanga kekutanga, zvakakosha kuomesa BOG yese nzira yekuyerera kwegasi uye nzira yekuyerera kwefiriji yemudziyo.
Mushure mekushanda kwenguva refu kwebhokisi rinotonhorera remvura inonyunguduka, kabhoni dhayokisaidhi yasara nehunyoro mugasi reBOG rakacheneswa zvinoungana muchikamu chekupisa kwakaderera chebhokisi rinotonhorera remvura inonyunguduka, zvichikonzera kuramba kwakanyanya uye kushandiswa kwesimba, uye zvinogonawo kukonzera kuti bhokisi rinotonhorera remvura inonyunguduka risashande zvakanaka. Saka, mushure menguva yebasa, bhokisi rinotonhorera remvura inonyunguduka richadziyirwa uye richanyungudutswa nenitrogen kana BOG gasi rinodziya.
Gasi reBOG rinobva panetwork yemapaipi enitrogen rinodziiswa nemagetsi kusvika pa60~70 ℃ , uye wobva wapinda munzira dzekuyerera dzinoenda mberi nekudzoka dzegasi rinopa mweya uye nzira dzekuyerera dzinoenda mberi nekudzoka dzefiriji mubhokisi rinotonhorera remvura kuti ridziye, wobva wadziiswa kubva mubhokisi rinotonhorera.
Rongteng inonyanya kugadzirisa gasi, kuchenesa gasi rechisikigo, kudzoreredza LPG, fekitari yeLNG uye seti yejenareta yegesi yechisikigo.
