141‐43‐5 Amazi atagira ibara yo gukuraho ikibiriti no gusukura gazi,
,

1. Monoetanolamine (MEA), izwi kandi kw’izina rya 2‐aminoéthanol, CAS No.141‐43‐5, ni amazi atagira ibara, agaragara kandi afise akamoto gatoyi nk’aka amoniya. Ivangwa n’amazi n’inzoga mu rugero urwo ari rwo rwose, kandi ifise imigwi y’ibikorwa vy’amine n’inzoga, bikazana ubushobozi bwiza cane bwo gukorana n’imiti. Igicuruzwa cacu c’inganda MEA gishika ku busuku 99%, gifise uburyo buhamye n’ubuhumane buke, ivyo bikaba bituma gikoreshwa cane mu nganda za peteroli na gazi.

Nk’uko ari ikintu gifata alkanolamine, MEA ikoreshwa cane mu gukuraho hydrogène sulfure (H2S) na carbone dioxide (CO2) mu gazi kavukire, gazi y’isuku n’imigende ya gazi y’ivyuma. Ishobora gufata neza ibihimba vya gazi y’aside mu bihe vy’ibikorwa vy’umuvuduko muto, kandi ishobora gusubirwamwo biciye mu gushushanya kugira ngo isubire gukoreshwa, bikagabanya cane igiciro c’ibikorwa vy’ibikoresho bisukura gazi. Uretse gukoresha gazi iryoshe, monoethanolamine ikora kandi nk’ikintu gitera ububabare mu gutunganya ivyuma, ibikoresho vya mbere vyo gukora ivyuma bikora ku mubiri, n’ikintu co kwongera ku mazi agendagenda mu nganda.

Monoethanolamine yacu ipfunyikwa mu ngoma z’icuma zisanzwe canke mu binogo vy’ibikoresho vya IBC vyo gutwara mu kiyaga. Turashira mu ngiro ubugenzuzi bukomeye bw’uburyo ku giciro cose, kandi Icemezo c’Isesengura (COA) gishobora gutangwa kugira ngo abakiriya basuzume imbere y’uko birungikwa. Nk’umucuruzi w’imiti w’Abashinwa yizigirwa, turashigikira ugusaba kw’ingoma nyinshi n’ugutuma IBC ikoresha imiti myinshi ku mahinguriro y’amavuta yo kw’isi yose, amahinguriro atunganya gaze kavukire n’abatanga imiti. Turagusavye ntutinye kutumenyesha kugira ngo ubone igiciro ca FOB gishasha n’urupapuro rw’ubuhinga rwuzuye ku bijanye n’amasoko menshi.
