1) Kufotokozera njira
Firiji yosakanikirana ya chipangizochi idzakhala ndi mafiriji oyeretsedwa a methane, nayitrogeni ndi hydrocarbon.
Kuchokera pamwamba pa bokosi lozizira, limalowa mu thanki yosungiramo zinthu pamalo olowera a compressor yosakanikirana ya refrigerant, kenako limapita ku compressor yoziziritsira. Pambuyo pokakamizidwa mu gawo loyamba, limalowa mu interstage cooler kuti liziziritse ndi kuzizira pang'ono, ndipo limapangidwa ndi mpweya mu interstage separator. Mpweya umalowa mu compressor kuti uzimangirire kachiwiri, high pressure refrigerant yomwe imatuluka mu interstage compressor imalowa mu final stage cooler kuti iziziritse ndipo imafupikitsidwa pang'ono, ndipo gasi ndi madzi osakaniza amalowa mu compactor yomaliza kuti asiyanitse.
Madzi oziziritsira apakati omwe amalekanitsidwa ndi cholekanitsa pakati pa siteji amakakamizidwa ndi pampu kenako amalowa mu cholekanitsa pambuyo pa choziziritsira chomaliza. Njirayi ndi yofunika kwambiri mu fakitale yaying'ono ya LNG.
Mpweya wozizira kwambiri ndi madzi oziziritsa omwe amalekanitsidwa ndi cholekanitsa chomaliza amanyamulidwa kupita ku bokosi lozizira ndi payipi. Madzi oziziritsa kwambiri amazizira mpaka -65 ℃ mu chosinthira kutentha, kuponderezedwa ndi kuchepetsedwa mphamvu ndikubwezeretsedwa ku njira yobwerera ya chosinthira kutentha. Mpweya wozizira kwambiri umapitirira kuziziritsidwa ndi kuchepetsedwa mphamvu mpaka -162°C mu chosinthira kutentha, kuponderezedwa ndi kuchepetsedwa mphamvu ndikubwezeretsedwa ku njira yotsitsimula ya kumapeto ozizira a chosinthira kutentha, kuponyedwa mmwamba, ndikugwirizanitsidwa ndi gawo lamadzimadzi loponderezedwa ndi kuchepetsedwa mphamvu pakati. Umayenderera mmwamba ndikutenga kutentha kuchokera ku mpweya woyeretsedwa ndi chosungira kutentha. Chosungira mpweya chotsitsimula chimaphikidwa ndi mpweya ndipo chimatuluka kuchokera kumapeto otentha a chosinthira kutentha. Kutentha kuli pafupifupi ~ 36 ℃, ndipo kuthamanga kuli pafupifupi 0.31MPa.A.
Kuchokera m'bokosi lozizira, thanki yokhazikika imalowa pamalo olowera a compressor yoziziritsira, ndipo imazungulira ndikuyikanikiza kuti isungidwe. Kutentha kwa firiji yotsika kwambiri yotuluka m'bokosi lozizira nthawi zambiri kumakhala kokwera kuposa mame, ndipo palibe madzi omwe adzapangidwe. Cholinga chokhazikitsa thanki yokhazikika ndikuwonetsetsa kuti madzi salowa mu compressor panthawi yogwira ntchito molakwika, panthawi yoyambitsa komanso panthawi yobwezeretsanso refrigerant. Madzi omwe asonkhanitsidwa mu thanki yokhazikika ya inlet satulutsidwa, koma amasinthidwa mwachilengedwe ndikubwezeretsedwa ku nthawi yoziziritsira, zomwe zingapewe kutayika kwa refrigerant pamene dongosolo silili bwino.
2) Magawo a kapangidwe
Mtundu wa kompresa Mpweya wozizira (wopangidwa ndi centrifugal), wozizira mpweya (process gas)
Kupanikizika kwa kuyamwa: 0.31 MPa.A
Kutentha kwa kuyamwa: ~36 ℃
Kuthamanga kwa utsi: 3.4 MPa.A (kutanthauza flange yotulutsira madzi ya choziziritsira chomaliza)
Kutentha kwa utsi: ~ 40℃ (kutanthauza flange yotulukira ya choziziritsira chomaliza)
3) Kuchuluka kwa ntchito
Chowongolera cholowera cha compressor ndi kusintha kwa compressor inlet ndi outlet return vanila zimagwiritsidwa ntchito kuti zisinthe kuchuluka kwa kusintha kwa katundu kwa 30 ~ 110%.
