Ezinqubweni zezimboni, ukusetshenziswa kwezincibilikisi ngokuvamile kubalulekile ekusebenzeni okuhlukahlukene. Kodwa-ke, ukwelashwa komoya oqukethe i-solvent kungadala izinselele zemvelo nezomnotho. Yilapho izinhlelo zokutakula ze-NMP (N-methyl-2-pyrrolidone) ziqala khona ukusebenza, zihlinzeka ngesixazululo esimeme sokuphathwa kwezinyibilikisi.
I-NMP iyincibilikisi ebalulekile esetshenziswa kabanzi ezimbonini ezifana nemithi, i-electronics kanye namakhemikhali e-petrochemicals. I-solvency ephezulu kanye nokuguquguquka okuphansi kuyenza ilungele izinhlelo zokusebenza eziningi. Kodwa-ke, izindleko zayo eziphezulu kanye nomthelela kwezemvelo kwenza ukutholwa kanye nokugaywa kabusha kwe-NMP emithonjeni yegesi ezinqubweni zezimboni kubaluleke kakhulu.
Amasistimu wokubuyisela we-NMPaklanyelwe ukuthwebula ngempumelelo futhi ahlukanise i-NMP emoyeni oqukethe i-solvent ukuze iphinde isetshenziswe ezinqubweni. Lokhu akusizi kuphela ukunciphisa ukusetshenziswa kwe-NMP kukonke, kodwa futhi kunciphisa umthelela wemvelo ohambisana nokulahlwa kwayo. Umoya ohlanzekile ogcwele i-solvent ungabe usubuyiselwa kunqubo noma uthuthele emkhathini, kuye ngezidingo zekhasimende.
Enye yezinzuzo ezinkulu zohlelo lokugaywa kabusha kwe-NMP umnikelo walo ezinkambisweni ezisimeme ekusebenzeni kwezimboni. Ngokusebenzisa lolu hlelo, izinkampani zinganciphisa kakhulu ukusetshenziswa kwe-solvent, ngaleyo ndlela zonge izindleko futhi zinciphise indawo yazo yemvelo. Ukwengeza, ukutholwa kanye nokusetshenziswa kabusha kwe-NMP kuhambisana nemigomo yomnotho oyindilinga, okuwukusebenzisa izinsiza ngendlela efanele kanye nokunciphisa ukumoshakala.
Ukwengeza, amasistimu okugaya kabusha e-NMP ahlinzeka ngezixazululo ezisebenzayo zokuthobela imithetho. Ngokugxila okwandayo emithethweni yezemvelo kanye namazinga okukhishwa kwegesi, izimboni zingaphansi kwengcindezi yokuphatha ngempumelelo ukukhishwa kwezinyibilikisi. Ngokutshala imali ohlelweni oluthembekile lokugaywa kabusha kwe-NMP, izinkampani zingaqinisekisa ukuthi zihlangabezana nezidingo zokuthobelana ezidingekayo kuyilapho zikhombisa ukuzibophezela kwazo ekunakekeleni imvelo.
Ngaphezu kwezinzuzo zemvelo nezokulawula, izinhlelo zokuvuselela kabusha ze-NMP nazo ziletha izinzuzo zezomnotho emabhizinisini. Ngokusebenzisa kabusha nokusebenzisa kabusha i-NMP, izinkampani zinganciphisa ukuthembela kwazo ekuthengeni izinto ezincibilikisa izinto ezingakaze zenzeke, zonga izindleko ngokuhamba kwesikhathi. Ukwengeza, ukuphathwa ngempumelelo kwezincibilikisi kunomthelela ekwenzeni ngcono inqubo iyonke kanye nokwanda kokusebenza kahle.
Kubalulekile ukuqaphela ukuthi ukuqaliswa kwezinhlelo zokubuyisela i-NMP kudinga ukucatshangelwa ngokucophelela kwezidingo eziqondene nenqubo kanye nokuba nokwenzeka kobuchwepheshe. Izinto ezifana nevolumu yomoya oqukethe i-solvent, ukugxila kwe-NMP, kanye nezimo zenqubo yonke zidinga ukuhlolwa ukuze kuklanywe isisombululo esingokwezifiso esizohlinzeka ngemiphumela engcono kakhulu.
Ngokufigqiwe,Amasistimu wokubuyisela we-NMPukuhlinzeka ngendlela eqhubekayo nengabizi ekuphathweni kwe-solvent ezindaweni zezimboni. Ngokuthwebula nokubuyisela i-NMP emoyeni, uhlelo lusekela imigomo yemvelo, ukuthobela imithetho kanye nezinzuzo zezomnotho. Njengoba imboni iqhubeka nokubeka eqhulwini ukusimama nokusebenza kahle kwezinsiza, ukwamukelwa kwezinhlelo zokugaywa kabusha kwe-NMP kuzodlala indima ebalulekile ekubumbeni ikusasa eliluhlaza, elinomthwalo wemfanelo omkhulu wokuphathwa kwezinyibilikisi.
