Imikhiqizo
Ikhwalithi ephezulu ye-Ethanolamine/ i-Monoethanolamine (MEA) CAS 141-43-5
Incazelo Yomkhiqizo
I-MEA ingakhiqizwa ngokuphendula i-ammonia/amanzi nge-ethylene oxide ngengcindezi engama-50–70 bar ukuze kugcinwe i-ammonia esigabeni soketshezi. Inqubo i-exothermic futhi ayidingi noma iyiphi i-catalyst. Isilinganiso se-ammonia ne-ethylene oxide sidlala indima ebalulekile ekunqumeni ukwakheka kwengxube ewumphumela. Uma i-ammonia iphendula ngemvukuzane eyodwa ye-ethylene oxide, kwakheka i-monoethanolamine, nama-molecule amabili e-ethylene oxide, i-diethanolamine yakheka kuyilapho kwakheka ama-moles amathathu e-ethylene oxide triethanolamine. Ngemuva kokusabela, i-distillation yengxube ewumphumela yenziwa kuqala ukususa i-ammonia namanzi ngokweqile. Khona-ke ama-amine ahlukaniswa kusetshenziswa ukusetha kwe-distillation yezinyathelo ezintathu.

Isicelo
| Ama-chemical reagents, ama-solvents, ama-emulsifiers |
| Ama-accelerator enjoloba, ama-corrosion inhibitors, ama-deactivators |
I-Monoethanolamine isetshenziswa njengama-reagents amakhemikhali, izibulala-zinambuzane, imithi, izinyibilikisi, izixhumi zikadayi, ama-accelerator enjoloba, ama-corrosion inhibitors kanye nama-surfactants, njll. Iphinde isetshenziswe njengezithakosi zegesi ene-asidi, ama-emulsifiers, ama-plasticizers, ama-ejenti avuthela injoloba, ukuphrinta nokudaya Indwangu emhlophe. i-anti-moth agent, njll. Ingasetshenziswa futhi njenge-plasticizer, i-ejenti evuvukalayo, i-accelerator kanye ne-foaming ejenti yezinsalela zokwenziwa kanye nenjoloba, kanye neziphakathi zezibulala-zinambuzane, imithi kanye nodayi. Kuphinde kube yimpahla engavuthiwe yeziwashi zokwenziwa, izifanisi zokuqinisa izimonyo, njll. Imboni yendwangu njengesicwebezi sokuphrinta nokudaya, i-antistatic agent, i-anti-moth agent, okokugeza. Ingasetshenziswa futhi njengesithako se-carbon dioxide, isithasiselo sikayinki, nesithasiselo se-petroleum.
Inzuzo
Izinga lomkhiqizo, inani elanele, ukulethwa okuphumelelayo, izinga eliphezulu lesevisi Inenzuzo kune-amine efanayo, i-ethanolamine, ngokuthi ukugxilisa okuphezulu kungase kusetshenziselwe amandla afanayo okugqwala. Lokhu kuvumela abacwengi ukuthi bakhuhle i-hydrogen sulfide ngenani eliphansi le-amine elijikelezayo ngokusetshenziswa kwamandla sekukonke.
