Iindaba

1. Kukho iinketho ezintathu xa uxinzelelo lwenitrogen yemveliso lungaphezulu kwe-8bar:

Isisombululo sokuqala: i-backflow yokwandisa inkqubo yokuvelisa i-nitrogen ixhotywe ngemveliso ye-nitrogen compressor ngexesha elifanayo.Ukuphela kwe-booster ye-expander icinezela i-nitrogen yemveliso okanye umoya ohamba phambili.Uxinzelelo lwe-compressor yomoya lolona xinzelelo luphantsi lokwandiswa kwe-backflow, kwaye izinga lokutsalwa kwemveliso linokufikelela kwi-38%.malunga.

Isisombululo sesibini: inkqubo yemveliso ye-nitrogen eyandisiweyo ixhotyiswe ngemveliso ye-nitrogen compressor ngaxeshanye, isiphelo se-booster ye-expander sicinezela imveliso ye-nitrogen okanye umoya ohamba kakuhle, ubuncinci boxinzelelo lwe-distillation yi-4bar, izinga lokutsalwa kwemveliso. inokufikelela malunga nama-45%, kwaye ubungakanani bolwelo Inokuvelisa ezinkulu.

Inketho yesithathu: inkqubo yokwandisa umva, i-nitrogen yemveliso ecinezelekileyo okanye umoya ohamba kakuhle kwi-booster ekupheleni kwe-expander, uxinzelelo olufunekayo kwimveliso ngokuthe ngqo ngaphandle kwebhokisi ebandayo, ukungahambi kakuhle kukuba uxinzelelo lokwandisa umva luphezulu, kubangela inxalenye yamandla asebenzayo ukuba angasetyenziswa.

2. Kukho iinketho ezimbini xa imveliso nitrogen phakathi 5 kunye 8 bar:

Isisombululo sokuqala: inkqubo yokwandisa umva, i-nitrogen yemveliso okanye umoya ohamba phambili ucinezelekile ekupheleni kwe-booster ye-expander.

Isisombululo sesibini: inkqubo yokwandisa ukuhamba kakuhle, isiphelo se-booster ye-expander sicinezela imveliso ye-nitrogen okanye umoya ohamba kakuhle, kwaye imveliso ixinzelelwe yi-nitrogen compressor.Le nkqubo inenzuzo enkulu xa uxinzelelo luphezulu.

3. Kukho iinketho ezine zemveliso yenitrogen kwi-0 ukuya ku-5 bar:

Isisombululo sokuqala: inkqubo yokwandiswa kwe-backflow, i-booster end of expander icinezela imveliso ye-nitrogen okanye umoya ohamba phambili, kwaye emva koko i-throttles ukuya kuxinzelelo olufunekayo, ngokubanzi i-4 ukuya kwi-5bar;Uxinzelelo lwe-backflow yokwandisa umoya icompressor iphezulu kunoxinzelelo lwemveliso ye-nitrogen 0.8bar ephezulu iyafuneka.

Isisombululo sesibini: inkqubo yokwandisa ukuhamba kakuhle, i-nitrogen yemveliso okanye umoya ohamba kakuhle ucinezelekile ekupheleni kwe-booster ye-expander, kunye noxinzelelo lwemveliso lufunyenwe ngokuthe ngqo, kunye ne-nitrogen yemveliso jikelele yi-4bar ukuya kwi-5bar.Uxinzelelo lwe-compressor yokwandisa ukuhamba kakuhle malunga ne-1.5bar ephezulu kune-nitrogen yemveliso, kodwa izinga layo lokukhutshwa liphezulu.Umoya owandisiweyo uqala ngoxinzelelo, emva koko wandise, kwaye emva koko uphume ngokuthe ngqo njengegesi yokuvuselela;xa isikali semveliso sikhulu kuno-10000Nm³/h, i-booster eyahlukileyo ingafakelwa Ukucinezela umoya wokwandisa, faka inqaba emva kokwandiswa, okunokunyusa umthamo wemveliso.

Indlela yesithathu: inkqubo yokulungiswa kweenqaba ezimbini.Le nkqubo isebenzisa ioksijini-etyebileyo embindini wenqaba ephezulu njengerhasi yokukhupha ukuze ikhutshelwe kwisicoci njengerhasi yokuhlaziya, kwaye isixa esikhulu seoksijini-etyebileyo emazantsi enqaba ephezulu ikhutshwa njengerhasi engeyiyo imveliso, enokunyusa uxinzelelo lokukhupha kwinqaba ephezulu., Dibana neemfuno zoxinzelelo lwenitrogen yemveliso, gcina ukusetyenziswa kwamandla oxinzelelo lwemveliso yenitrogen.Le nkqubo inokufumana i-nitrogen yemveliso kwiingcinezelo ezimbini ze-0 ukuya ku-2 bar kunye ne-5 bar okanye ngaphezulu.

Isisombululo sesine: inkqubo ye-double-tower-condensation process, ukubetha i-oksijini ezantsi kwinqaba ephezulu, uze uye kwintloko ye-condensation phezulu kwinqaba, ukuze ufumane i-0 ukuya kwi-3 bar kunye ne-5 ukuya kwe-7. bar okanye i-nitrogen yemveliso ephezulu, izinga lokutsalwa kwemveliso yale nkqubo Iphakamileyo, ukuya kuthi ga kwi-60%.
