1) Inkcazo yenkqubo
I-refrigerant exutyiweyo yale yunithi iya kuba nee-refrigerants ezicociweyo ze-methane, i-nitrogen kunye ne-hydrocarbon.
Ukusuka phezulu kwebhokisi ebandayo kungena itanki ye-buffer kwindawo yokungena ye-compressor ye-refrigerant exutyiweyo, ize iye kwi-compressor ye-refrigerant. Emva kokuba icinezelwe kwinqanaba lokuqala, ingena kwi-interstage cooler ukuze iphole kwaye ifume kancinci, kwaye ifakwa igesi kwindawo yokwahlulahlula ulwelo phakathi kwe-interstage. Igesi ingena kwi-compressor ukuze icinezelwe okwesibini, i-refrigerant enoxinzelelo oluphezulu kwindawo yokukhupha ye-compressor yesibini ingena kwi-final stage cooler ukuze iphole kwaye ifumelelwe kancinci, kwaye umxube wegesi-ulwelo ungena kwindawo yokwahlulahlula yesigaba sokugqibela ukuze ihlukane.
Ulwelo oluphakathi olufakwa kwifriji oluhlukaniswe yisihluzo esiphakathi lucinezelwa yipompo luze lungene kwisihluzo emva kwesipholile sokugqibela. Le nkqubo ayibalulekanga kakhulu kwisityalo esincinci se-LNG.
Igesi yefriji enoxinzelelo oluphezulu kunye nolwelo lwefriji olwahlulwe sisahluli sokugqibela zithuthwa zisiwe kwibhokisi ebandayo ngepayipi. Ulwelo lwefriji olunoxinzelelo oluphezulu luyapholiswa ukuya kwi -65 ℃ kwi-heat exchanger, lupholiswe kwaye luncitshiswe kwaye lubuyiselwe kwindlela yokubuyela ye-heat exchanger. Igesi yefriji enoxinzelelo oluphezulu iyaqhubeka ipholiswa kwaye incitshiswe ukuya kwi -162°C kwi-heat exchanger, ipholiswe kwaye incitshiswe kwaye ibuyiselwe kwitshaneli ye-reflux yesiphelo esibandayo se-heat exchanger, ipholiswe phezulu, kwaye idityaniswe nesigaba solwelo olupholiswe kwaye luncitshiswe embindini. Ihamba phezulu kwaye ifunxe ubushushu kwigesi ecociweyo kunye ne-high-pressure refrigerant. I-reflux refrigerant yonke iyapholiswa ibe yigesi kwaye iphuma kwisiphelo esishushu se-heat exchanger. Ubushushu bumalunga ne ~ 36 ℃ , kwaye uxinzelelo lumalunga ne 0.31MPa.A .
Ukusuka kwibhokisi ebandayo kungena itanki yokulinganisela kwindawo yokungena yecompressor yefriji, ize ijikeleze kwaye icinezele ukuze ifrijiwe. Ubushushu befriji enoxinzelelo oluphantsi ephuma kwibhokisi ebandayo buhlala buphezulu kune-dew point, kwaye akukho lwelo luya kuveliswa. Injongo yokuseta itanki yokulinganisela yokungena kukuqinisekisa ukuba ulwelo alungeni kwicompressor ngexesha lokusebenza okungaqhelekanga, ngexesha lokuqalisa kunye nexesha lokugcwalisa kwakhona ifriji. Ulwelo oluqokelelwe kwitanki yokulinganisela yokungena alukhutshwa, kodwa luvuthwa ngokwemvelo kwaye lubuyiselwe kumjikelo wokufrijiwa, okunokuthintela ukulahleka kwefriji xa inkqubo ingaqhelekanga.
2) Iiparamitha zoyilo
Uhlobo lwesiguquli I-Centrifugal, epholileyo emoyeni (igesi yenkqubo)
Uxinzelelo lokufunxa: 0.31 MPa.A
Ubushushu bokufunxa: ~36 ℃
Uxinzelelo lokukhupha umoya: 3.4 MPa.A (ebhekisa kwiflange yokuphuma yesixhobo sokupholisa sokugqibela)
Ubushushu bokukhupha umoya: ~ 40℃ (ebhekisa kwi-flange yokuphuma ye-cooler yokugqibela)
3) Ububanzi besicelo
I-compressor inlet guide vane kunye ne-compressor inlet kunye ne-outlet return adjustment zamkelwe ukuze kulungiswe uluhlu lokulungiswa komthwalo oluyi-30 ~ 110%.
