Intshayelelo

I-MDEA yegesi yendalo ye-desulphurization (i-desulfurization) skid, ekwabizwa ngokuba yi-MDEA ye-sweeting skid kunye neyunithi yegesi yendalo desulfurization, sisixhobo esiphambili ekucoceni igesi yendalo okanye ukulungiswa kwegesi yendalo.

Iyunithi ye-MDEA yegesi yendalo ye-desulfurization isoloko yamkelwa xa i-carbon sulphur yegesi yokutya iphezulu kakhulu, kwaye xa ukususwa okukhethiweyo kwe-H₂I-S iyafuneka ukufumana irhasi yeasidi efanelekileyo kwiClaus plant processing, kunye nezinye iimeko ezinokukhethwa ukususa i-H₂S; Xa kususwa uH₂S kunye nokususa isixa esikhulu se-CO₂, i-MDEA ingasetyenziswa njengendlela edibeneyo ye-amine;

Okwangoku, ubuchwephesha obuphambili be-desulfurization obusetyenziswa kwimveliso yemizi-mveliso ekhaya nakwamanye amazwe yile: i-desulfurization eyomileyo (ngokomzimba), i-biological desulfurization kunye ne-desulfurization emanzi.

I-desulfurization emanzi ibandakanya indlela yokufunxa kunye nendlela ye-oxidation emanzi. Indlela yokufunxa imichiza, emelwe yi-alcohol amine absorption, isetyenziswe ngokubanzi kwishishini. I-Hydrogen sulfide kwigesi idluliselwa kwisigaba solwelo ukucoca igesi.

Itekhnoloji yeDesulfurization

Itekhnoloji ye-biological desulfurization, kwimeko ye-micro oxygen, inokuguqula i-hydrogen sulfide ibe yi-elemental sulfure, kodwa iteknoloji ye-biological desulfurization ayikavuthwa okwangoku.

Itekhnoloji ye-Desulfurization eyomileyo ibandakanya indlela ye-iron oxide, indlela ye-carbon esebenzayo, indlela ye-molecular sieve, indlela yokutshintshiselana i-ion, indlela yokwahlukana kwenwebu, indlela ye-biochemical, njl.

iindlela desulfurization

I-amorphous iron hydroxide (inkqubo eyomileyo). Iimpawu: ineempawu zokuchaneka okuphezulu kwe-desulfurization, umthamo wesulfure ephezulu, amandla amahle kunye nokungahoywa. Isetyenziswa ngokubanzi ekukhutshweni kwe-hydrogen sulfide kwigesi yendalo, igesi yokwenziwa, i-biogas, igesi yamalahle, i-methane yamalahle kunye nezinto ezahlukeneyo eziqulethe iikhemikhali zesulfure; I-amorphous hydroxyl oxidation desulfurization yi-reaction desulfurization, engakwazi ukulawula ubunzulu be-desulfurization. Yinkqubo entle yokususa isalfurization. Ngokuxutywa kwe-desulfurizer kunye nokungena kwe-desulfurization tower, umphumo we-desulfurization uya kuncipha kakhulu, kwaye umxholo we-hydrogen sulfide kwigesi yendalo ecocekileyo uya kunyuka ngokukhawuleza, ngoko ke kuyimfuneko ukutshintsha i-desulfurizer ngexesha.
