Isityalo se-LNG esingu-3.5~7 se-MMSCFD kunye nesityalo se-LNG esifakwe kwi-Skid

Inkcazo:

Igesi yendalo enyibilikayo, ebizwa ngokuba yi-LNG, iyenza irhasi yendalo ibe lulwelo ngokupholisa igesi yendalo engcolileyo phantsi koxinzelelo oluqhelekileyo ukuya kwi-162 ℃. Ulwelo lwegesi yendalo lunokonga kakhulu indawo yokugcina kunye nokuthutha, kwaye luneengenelo zexabiso elikhulu leekhalori, ukusebenza okuphezulu, okulungelelaniswa nokulawulwa komthwalo wedolophu, okulungelelaniswa nokukhuselwa kwendalo, okunciphisa ungcoliseko lwedolophu njalo njalo.

Ulwelo luphambili kwimveliso ye-LNG. Okwangoku, iinkqubo zokunyibilikisa igesi yendalo ezivuthiweyo ziquka inkqubo yokunyibilikisa igesi, inkqubo yokunyibilikisa igesi efrijini exutyiweyo kunye nenkqubo yokunyibilikisa igesi nge-expander.

Inkqubo yokunyibilikisa igesi yendalo yeCascade isebenzisa iindawo ezahlukeneyo zokubilisa zefriji phantsi koxinzelelo oluqhelekileyo ukunciphisa ubushushu befriji inyathelo ngenyathelo ukufezekisa injongo yokunyibilikisa igesi yendalo.

I-Mixed refrigerant cycle (MRC) yinkqubo apho iintlobo ezingaphezu kwesihlanu zee-multi-component mixed refrigerants, ezifana ne-C1 ~ C5 Hydrocarbons kunye ne-N2, zisetyenziswa njengolwelo olusebenzayo ukuze zijike, ziphele kwaye zande inyathelo ngenyathelo ukuze zifumane amandla okukhenkceza kumanqanaba obushushu ahlukeneyo, zize emva koko zipholise kwaye zinyibilikise igesi yendalo kancinci kancinci. Inkqubo yokukhenkceza i-Mixed refrigerant yahlulwe kwiindidi ezininzi ezahlukeneyo zomjikelo wokukhenkceza.

Inkqubo yokunyibilikisa ulwelo nge-expander ibhekisa kwinkqubo yokunyibilikisa ulwelo ngegesi yendalo ngokusebenzisa i-refrigerant yoxinzelelo oluphezulu ukwenza i-reverse Claude cycle refriji kunye ne-adiabatic expander expander.

Inkqubo yenkqubo ibandakanya ikakhulu: iyunithi yokulawula uxinzelelo lwegesi yokuphakelwa kunye neyokulinganisa, iyunithi yokucoca igesi yendalo kunye neyunithi yokunyibilikisa igesi yendalo, inkqubo yokugcina ifriji, inkqubo yoxinzelelo olujikelezayo lwefriji, iyunithi yokugcina kunye nokulayisha i-LNG.

Igesi yendalo engena kwisikhululo idlula kuqala kwiyunithi yokulawula uxinzelelo kunye neyokulinganisa, efezekisa ulawulo loxinzelelo kunye nokulinganisa igesi yendalo engenayo; Igesi yendalo ingena kwiyunithi yokucoca igesi yendalo, apho igesi yendalo isuswa khona i-CO2, isuswe i-H2S kwaye inyangwa ngokuphelelwa ngamanzi emzimbeni. Inkqubo ye-MDEA iyacetyiswa ukuze kususwe i-carbonization kunye nokususwa kwe-H2S, inkqubo yokuphelelwa ngamanzi emzimbeni ngesihluzo se-molecular kunye neenqaba ezintathu OKANYE inkqubo yokuphelelwa ngamanzi emzimbeni ye-TEG iyacetyiswa ukuze kusetyenziswe ukuphelelwa ngamanzi emzimbeni; Kwaye Kuyacetyiswa ukuba kusetyenziswe i-BOG ebuyiselweyo necinezelweyo kwigesi yokuvuselela;

Igesi yendalo ecociweyo ifakwa kwiyunithi yokunyibilikisa igesi yendalo, i-mixed refrigerant (inkqubo yokunyibilikisa i-MRC) iyacetyiswa kwi-liquefaction yegesi yendalo; i-LNG enyibilikisiweyo igcinwa kwi-tank yokugcina, kwaye inkqubo yokugcina umoya kunye nobushushu obuphantsi iyacetyiswa kwi-LNG yokugcina. Itanki enye yokugcina umoya enobushushu obuphantsi ixhotyiswe nge-BG compressor, kwaye i-BOG compressor isetyenziselwa ukucinezela i-BOG ngaphambi kokuba ingene kwi-molecular sieve dryer Regeneration, kuxhomekeke kwi-cryogenic pump ukuze kufezekiswe ukufakwa.
