Inkcazo yenkqubo yeyunithi nganye yesityalo sokuphinda sinyibilike i-BOG

I-BOG yetanki yokugcina i-LNG ingena kwibhokisi ebandayo yolwelo emva koxinzelelo kunye nokulinganisa, ipholiswe, inyibilikiswe, kwaye ipholiswe kakhulu kwi-plate-fin heat exchanger, kwaye ibuyela kwitanki yokugcina i-LNG njengemveliso ye-LNG emva kokuyibopha.

Eyona ndlela iphambili yetekhnoloji yesi sixhobo yile:

Inkqubo yokuphola ye-MRC (mixed refrigerant) cycle isetyenziselwa ukunyibilikisa yonke igesi ye-BOG ecociweyo;

Le nkqubo ibandakanya:

Iyunithi yokwahlulahlula kunye noxinzelelo lwegesi yokufunxa;

Inkqubo yokunyibilikisa ulwelo lwe-LNG;

Iyunithi yokufrijisa exutyiweyo;

1) Iyunithi yokwahlula igesi kunye neyoxinzelelo

1) Inkcazo yenkqubo

Igesi ye-BOG ingena kwi-gasifier efudunyezwa ngumoya kunye ne-feed gas heat exchanger, kwaye emva kokucinezelwa, ukwahlukana, kunye nokulinganisa, ingena kwinkqubo yokunyibilika kolwelo esezantsi.

Izixhobo eziphambili zenkqubo yi-gasifier efudumeleyo yomoya, i-feed gas heat exchanger, i-flow meter, iyunithi ye-booster compressor, njl.

2) Iyunithi yolwelo

1) Inkcazo yenkqubo

Ngaphambi kokungena kwiyunithi yokunyibilikisa ulwelo, igesi yokucoca kufuneka ihlolwe ukuqinisekisa ukuba umxholo wamanzi, ii-aromatics zizonke kunye nomxholo we-mercury ziyahlangabezana neemfuno zokungena kwiyunithi yokunyibilikisa ulwelo. iyunithi yokunyibilikisa ulwelo.

I-BOG ecocekileyo  Igesi ingena kuqala kwi-liquefaction heat exchanger kwibhokisi ebandayo, ipholiswa kancinci kancinci yi-refrigerant exutyiweyo ebuyayo enobushushu obuphantsi, ize ipholiswe kakhulu ukuya kwi--162 °C , emva koko ingena kwisahluli se-LNG ukuze ifumane iimveliso ze-LNG.

Izixhobo eziphambili yibhokisi ebandayo, equka ikakhulu ii-plate heat exchangers, ii-separators ezahlukeneyo, njl.

3) Iyunithi yokucinezela kunye nokulinganisa i-refrigerant exutyiweyo

1) Inkcazo yenkqubo

I-refrigerant exutyiweyo yesi sixhobo iya kwenziwa yi-methane ecocekileyo, i-nitrogen kunye nee-hydrocarbon refrigerants.

Uxinzelelo lwe-Refrigerant luquka i-compressor ye-refrigerant eshushu kunye ne-compressor ye-refrigerant ebandayo. I-compressor ye-refrigerant eshushu ikakhulu inika amandla okupholisa e-top-temperature ephezulu, kwaye i-compressor ye-refrigerant ebandayo ikakhulu inika amandla okupholisa e-top-temperature ephantsi.

Izixhobo eziphambili yi-refrigerant cycle compressor, i-refrigerant proportional tank, njl.

2) Iiparamitha zoyilo

Umthamo wokwenza ulwelo: iitoni ezingama-224.7/ngosuku

Uhlobo lweCompressor: I-Screw Compressor

Iicompressor ezi-2 (icompressor efrijini e-1 enobushushu obuphezulu nobuphantsi nganye)

Uxinzelelo lokufunxa 0.3MPa.G

Ubushushu bokufunxa 40.0 ℃

Uxinzelelo lokukhupha umoya yi-1.9MPa.G (ebhekisa kwiflange yokuphuma yesixhobo sokupholisa sokugqibela)

Ubushushu bokukhupha umoya 40 °C (ebhekisa kwi-outlet flange ye-cooler yokugqibela)

3) Uluhlu lokuziqhelanisa

50% ~ 110%.

4) Iyunithi yokufudumeza ibhokisi ebandayo

1) Umsebenzi wenkqubo

Ngaphambi kokuba uqale okokuqala, kuyimfuneko ukomisa yonke i-BOG  indlela yokuhamba kwegesi kunye nendlela yokuhamba kwesixhobo esifrijini.

Emva kokusebenza ixesha elide kwebhokisi ebandayo yokunyibilikisa ulwelo, intsalela yekhabhoni diokside kunye nokufuma kwigesi yeBOG ecociweyo ziya kuqokelelana kwindawo enobushushu obuphantsi yebhokisi ebandayo yokunyibilikisa ulwelo, nto leyo ebangela ukwanda kokumelana nokusetyenziswa kwamandla, kwaye inokubangela ukuba ibhokisi ebandayo yokunyibilikisa ulwelo ingaphumeleli ukusebenza ngokuqhelekileyo. Ke ngoko, emva komjikelo womsebenzi, ibhokisi ebandayo yokunyibilikisa ulwelo iya kufudunyezwa kwaye inyibilikiswe ngenitrogen efudumeleyo okanye igesi yeBOG.

2) Inkcazo yenkqubo

Igesi ye-BOG evela kwinethiwekhi yemibhobho ye-nitrogen ifudunyezwa ngombane ukuya kuma-60~70 ℃ , ize ingene kwiindlela zokuhamba ezihamba phambili nezibuyela umva zegesi yokutya kunye neendlela zokuhamba ezihamba phambili nezibuyela umva zefriji kwibhokisi ebandayo yolwelo ukuze ifudumale, ize emva koko ifudumale isuka kwibhokisi ebandayo.

I-Rongteng igxile kunyango lwemithombo yamanzi endle, ukucocwa kwegesi yendalo, ukubuyiswa kwe-LPG, isityalo se-LNG kunye iseti yejenereyitha yegesi yendalo.
