Ijeneretha Yenitrojeni Ekhethekile Yokusetshenziswa Kwezinto Ezintsha Embonini YePetrochemical

Ukusetshenziswa kwezinto ezintsha embonini ye-petrochemical

I-nitrogen isetshenziswa kakhulu embonini yamakhemikhali njengegesi yezinto ezingavuthiwe, ukuvunguza kwepayipi, ukushintshwa kwe-atmosphere, umoya ovikelayo, ukuthuthwa komkhiqizo, njll. I-nitrogen isetshenziswa kakhulu ezimbonini ezifana namakhemikhali, i-spandex, irabha, amapulasitiki, amathayi, i-polyurethane, i-biotechnology, kanye nezimboni. Izimboni eziningi zamakhemikhali azinazo izidingo eziphezulu zokuhlanzeka kwe-nitrogen, futhi eziningi zingasetshenziswa ngobumsulwa obungaphezu kuka-98%, njenge-acrylic acid oxidation-proof, i-float glass process process, njll. Ngokusebenzisa izici zamakhemikhali ze-nitrogen, kungadalwa umoya we-anaerobic ezinqubweni zamakhemikhali ukuze kuthuthukiswe ukuphepha kokukhiqiza. I-nitrogen ingasetshenziswa futhi njengomthombo wamandla okuthutha uketshezi.

Faka esikhundleni, hlanza, vala, thola ukuvuza, futhi usule igesi evikelayo yokucisha; Igesi esetshenziselwa ukuvuselelwa kabusha kwe-catalyst, ukuhlukaniswa kwe-petroleum, ukukhiqizwa kwamakhemikhali e-fiber, njll.

Thuthukisa izinqubo zokucutshungulwa kwe-petroleum kanye nezinqubo zokucwenga, ukugcinwa kukawoyela kanye nokucindezelwa kwemithombo yasensimini kawoyela negesi, ukuhlanzwa kwamapayipi nokuhlanza, ukubuyiswa kwe-solvent, njll.

Ukuhlanzwa kwe-nitrogen yokugcina, iziqukathi, imibhoshongo yokuqhekeka kwe-catalytic, amapayipi, njll; Ukuhlolwa kokuvuza komfutho womoya wesistimu yamapayipi, njll.

Imboni yamakhemikhali iyimboni esetshenziswa kakhulu ezintweni ze-nitrogen, futhi okwamanje esetshenziswa kakhulu i-polyurethane (PVC) enobumsulwa obungama-99.5% kanye nezinga lokugeleza okuphezulu. I-Polypropylene (PE), enobumsulwa obungu-99.9% kanye nezinga lokugeleza okuphezulu, ihlukaniswe izingxenye ezimbili zokufakwa kwe-nitrogen. Ingxenye yokuqala idinga u-99.9% we-nitrogen ukuze kulayishwe futhi kuthululwe ama-activator nama-catalysts, kuyilapho igedlela lokusabela lisebenzisa i-nitrogen engu-99.5%, ngokuvamile edinga ukuhlanzeka kwe-99.9%. unokuphila kwesevisi okufushane.

I-polyethylene ne-aniline zidinga ukuhlanzeka kwe-nitrogen okungama-99.95%. Emikhiqizweni ye-petrochemical efana ne-aniline, i-nitrogen esetshenziselwa ukuvuselelwa kwe-catalyst iphakeme ngokuphindwe kane kunokuvamile, kodwa ngempilo yesevisi emfushane. Ku-anhydride yesilisa ne-ethanol, ukuhlanzeka kwe-nitrogen okungama-99.9% ngokuvamile kuyadingeka. Ngemikhiqizo ye-petrochemical efana ne-polyoxymethylene, ukuhlanzeka kwe-nitrogen kwe-99.9% kuyadingeka. Embonini ye-petroleum, i-nitrogen ingasetshenziselwa ukuhlanzwa kwe-nitrogen yamapayipi neziqukathi, ukugcwaliswa kwe-nitrogen emathangini okugcina, ukushintshwa, ukutholwa kokuvuza, ukuvikelwa kwegesi evuthayo, kanye ne-diesel hydrogenation kanye ne-catalytic reforming. Ubumsulwa be-nitrogen ngokuvamile bungama-99.9%.

I-Phthalic anhydride idinga ukuhlanzeka kwe-nitrogen okungama-99%.

I-polyester, impahla eluhlaza ekhuphuka nomfula i-PTA (i-p-phenylenedimethanol ecolisisiwe), ubumsulwa be-nitrogen obudingekayo bungama-95%, ngokuvamile buthathwa njengo-99%.

Enqubweni yokukhiqiza ye-PTA, i-nitrogen ene-high-purity isetshenziselwa ukuqhuma amabhamuza, ukukala izinga loketshezi le-ethylene glycol yezinto zokusetshenziswa emikhunjini yokusabela kwezinga lokushisa eliphakeme neliphansi, kukala umehluko wengcindezi phakathi kokuphela komfutho ophakeme nophansi, futhi kudluliselwe isignali evamile engu-4-20mA, bese iguqulwa ibe ukuphakama kwezinga le-liquid. Futhi sebenzisa i-nitrogen ehlanzekile kakhulu ukuze ulinganise ingcindezi yesistimu ye-vacuum, futhi usebenzise i-nitrogen ehlanzekile ukuze ugeze isihlungi kunqubo yokukhiqiza ye-PTA. Ama-chips e-polyester ngokuvamile asebenzisa i-nitrogen enobumsulwa obungu-99% ukuya ku-99.999% kuye ngenqubo yangempela.

Lapho umoya ocindezelwe ngokuhlanzwa nokomiswa, Isisekelo ku-Aerodynamics, i-nitrogen nomoya-mpilo osemoyeni esisefweni semolekyuli ye-zeolite (ZMS) ku-Pressure swing adsorption izosebenza ngezinga elihlukile lokusabalalisa ngokusebenzisa i-nitrogen. Umoya-mpilo esisefweni se-carbon molecular phezu kwezinga lokusabalalisa ungaphezu kwe-nitrogen. Lapho i-adsorption ingekho ebhalansini, umoya-mpilo wawumuncwa ngesihlungo se-carbon molecular ngobuningi, futhi i-nitrogen yagxiliswa futhi yathuthukiswa esigabeni segesi ukuze kuzuzwe ukuhlukaniswa kwe-oxygen ne-nitrogen.
