Monoethanolamine yeGiredhi reMaindasitiri MEA 99% CAS 141‑43‑5 Mvura Isina Ruvara Yekubvisa Sulphurization yeGasi reChisikigo & Kuchenesa Gasi,
,

1. Monoethanolamine (MEA), inozivikanwawo se2-aminoethanol, CAS Nhamba 141-43-5, imvura isina ruvara, inoonekera uye ine kunhuhwirira kudiki kwakafanana neammonia. Inosanganiswa nemvura nedoro chero papi zvapo, uye ine mapoka anoshanda ese ari maviri eamine nedoro, zvichiunza reactivity yakanaka yemakemikari. Chigadzirwa chedu cheMEA chemhando yeindasitiri chinosvika pakuchena kwe99%, chine mhando yakagadzikana uye kusvibiswa kwakaderera, izvo zvinoita kuti chishandiswe zvakanyanya muindasitiri yemafuta negesi.

Sezvo iri alkanolamine inonwisa mvura, MEA inonyanya kushandiswa kubvisa hydrogen sulfide (H₂S) uye carbon dioxide (CO₂) kubva mugasi rechisikigo, gasi rekuchenesa uye magasi ekugadzira. Inogona kunwisa zvine mwero zvikamu zvegasi reacid pasi pemamiriro ekushanda asina kumanikidzwa zvakanyanya, uye inogona kuvandudzwa kuburikidza nekudziisa kuti ishandiswezve cyclic, zvichideredza zvakanyanya mari yekushanda kwezvigayo zvekurapa gasi. Kunze kwekushandiswa kwekunakisa gasi, monoethanolamine inoshandawo senzira yekudzikamisa mukugadzirisa simbi, zvinhu zvisina kugadzirwa zve surfactant synthesis, uye corrosion inhibitor additives yemvura inotenderera mumaindasitiri.

Monoethanolamine yedu yakazadzwa mumadhiramu esimbi akajairwa kana matangi eIBC tote ekufambisa mugungwa. Isu tinoshandisa kudzora kwakasimba kwemhando yega yega, uye Chitupa Chekuongorora (COA) chinogona kupihwa kuti vatengi vaongorore vasati vatumira. Sevatengesi vemakemikari vekuChina vakavimbika, tinotsigira kuodha madhiramu akawanda uye kutumirwa kweIBC akawanda kune vanochenesa mafuta pasi rose, mafekitori ekugadzira gasi rechisikigo uye vanogovera makemikari. Ndapota inzwa wakasununguka kutibata kuti uwane mutengo weFOB wazvino uye pepa rakazara reruzivo rwehunyanzvi rwekutenga zvakawanda.
