1. Kunezinketho ezintathu lapho umfutho we-nitrogen womkhiqizo ungaphezu kuka-8bar:
Isixazululo sokuqala: inqubo yokukhiqiza i-nitrogen yokwandisa i-backflow ifakwe i-compressor ye-nitrogen yomkhiqizo ngesikhathi esisodwa.Isiphetho se-booster se-expander sicindezela i-nitrogen yomkhiqizo noma umoya oya phambili.Ingcindezi ye-compressor yomoya iyingcindezi ephansi yokunwetshwa kwe-backflow, futhi izinga lokukhishwa komkhiqizo lingafinyelela ku-38%.mayelana.
Isixazululo sesibili: inqubo yokukhiqiza i-nitrogen yokwandisa ukugeleza okuhle ifakwe i-compressor ye-nitrogen yomkhiqizo ngesikhathi esifanayo, ukuphela kwe-booster ye-expander icindezela umkhiqizo we-nitrogen noma umoya wokugeleza okuhle, ingcindezi encane yombhoshongo we-distillation yi-4bar, izinga lokukhishwa komkhiqizo. ingafinyelela cishe ku-45%, kanti inani loketshezi Ingakhiqiza elikhudlwana.
Inketho yesithathu: inqubo yokwandisa i-backflow, i-nitrogen yomkhiqizo ocindezelweyo noma umoya wokugeleza okuhle ekugcineni kwe-booster ye-expander, ingcindezi edingekayo yomkhiqizo ngokuqondile ngaphandle kwebhokisi elibandayo, okungalungile ukuthi ukucindezela kokunwetshwa kwe-backflow kuphezulu, kubangela ingxenye yamandla asebenzayo okufanele angasetshenziswa.
2. Kunezinketho ezimbili lapho i-nitrogen yomkhiqizo iphakathi kwamabha angu-5 no-8:
Isixazululo sokuqala: inqubo yokwandisa i-backflow, i-nitrogen yomkhiqizo noma umoya oya phambili ucindezelwa ekugcineni kwe-booster ye-expander.
Isixazululo sesibili: inqubo yokwandisa ukugeleza okuhle, ukuphela kwe-booster ye-expander kucindezela umkhiqizo we-nitrogen noma umoya wokugeleza okuhle, futhi umkhiqizo ucindezelwa yi-nitrogen compressor.Le nqubo inenzuzo enkulu lapho ingcindezi iphezulu.
3. Kunezinketho ezine ze-nitrogen yomkhiqizo kubha engu-0 kuye ku-5:
Isixazululo sokuqala: inqubo yokunwetshwa kwe-backflow, isiphetho se-booster se-expander sicindezela umkhiqizo we-nitrogen noma umoya oya phambili, bese ucindezela ukucindezela okudingekayo, ngokuvamile okungu-4 kuya ku-5bar;ingcindezi ye-backflow air compressor yokwandisa iphezulu kunokucindezela komkhiqizo we-nitrogen 0.8bar high edingekayo.
Isixazululo sesibili: inqubo yokwandisa ukugeleza okuhle, i-nitrogen yomkhiqizo noma umoya wokugeleza oqondile ucindezelwa ekugcineni kwe-booster ye-expander, futhi ingcindezi yomkhiqizo itholakala ngokuqondile, kanti i-nitrogen yomkhiqizo jikelele ingu-4bar kuya ku-5bar.Ukucindezela kwe-compressor yokwandisa ukugeleza okuhle cishe ku-1.5bar ephakeme kune-nitrogen yomkhiqizo, kodwa izinga layo lokukhipha liphezulu.Umoya owandisiwe uqala ngokucindezelwa, bese uyanwetshwa, bese uphuma ngokuqondile njengegesi yokuvuselela;uma isikali somkhiqizo sikhulu kuno-10000Nm³/h, ingafakwa i-booster ehlukile Ukuze ucindezele umoya onwetshiwe, faka umbhoshongo ngemva kokunwetshwa, okungase kwenyuse ivolumu yomkhiqizo.
Inketho yesithathu: inqubo yokulungiswa kwemibhoshongo emibili.Le nqubo isebenzisa okunothile komoyampilo phakathi kombhoshongo ongaphezulu njengegesi yokukhipha umoya ezokhishelwa okokuhlanza njengegesi yokuvuselela, futhi inani elikhulu le-oksijini ecebile ngezansi kombhoshongo ongaphezulu likhishwa njengegesi engeyona yomkhiqizo, okungase kwandise ukucindezelwa kokukhishwa kombhoshongo ongaphezulu., Hlangana nezidingo zengcindezi ye-nitrogen yomkhiqizo, londoloza ukusetshenziswa kwamandla kokucindezelwa komkhiqizo we-nitrogen.Le nqubo ingathola i-nitrogen yomkhiqizo ngezingcindezi ezimbili ze-0 kuya ku-2 bar kanye ne-5 bar noma ngaphezulu.
Isixazululo sesine: inqubo ye-double-condensation ye-double-tower, idonsa umoya-mpilo phansi kombhoshongo ongaphezulu, bese uya ekhanda le-condensation phezulu kombhoshongo, ukuze uthole u-0 kuya ku-3 bar kanye no-5 kuya ku-7. ibha noma i-nitrogen yomkhiqizo ephakeme, izinga lokukhishwa komkhiqizo lale nqubo Liphezulu, lifika cishe ku-60%.
