Ubushinwa Bwiza Bwiza bwo Gutunganya Ibicuruzwa byoherezwa mu mahanga - Skide yo kuryoshya gazi - Rongteng

Intangiriro

MDEA ya gazi isanzwe ya desulfurizasiya (desulfurizasi), nanone yitwa MDEA sweeting skid hamwe na gasutamo ya gazi isanzwe, nigikoresho cyingenzi mugusukura gaze karemano cyangwa gutunganya gaze gasanzwe.

Igice cya MDEA gisanzwe cya gazi isanzwe ikoreshwa mugihe karubone ya karubone ya gazi yo kugaburira iba myinshi, kandi mugihe cyo gukuraho H₂S irakenewe kugirango ubone gaze ya acide ikwiranye nogutunganya ibihingwa bya Claus, nibindi bintu bishobora guhitamo gukuraho H.₂S; Iyo ukuraho H.₂S no gukuraho umubare utari muto wa CO₂, MDEA irashobora gukoreshwa nkuburyo bwa amine buvanze;

Kugeza ubu, tekinoroji nyamukuru ya desulfurizasiyo ikoreshwa mu musaruro w’inganda mu gihugu ndetse no mu mahanga ni: desulfurizasi yumye (physique), desulfurizasi y’ibinyabuzima na desulfurizasi.

Amazi meza arimo uburyo bwo gukuramo hamwe nuburyo bwa okiside itose. Uburyo bwo kwinjiza imiti, bugereranywa no kunywa inzoga amine, bwakoreshejwe cyane mu nganda. Hydrogen sulfide muri gaze yimurirwa mugice cyamazi kugirango isukure gaze.

Ikoranabuhanga rya Desulfurisation

Ikoranabuhanga rya desulfurizasiya y’ibinyabuzima, mu miterere ya ogisijeni ya micro, irashobora guhindura hydrogène sulfide mo sulfure yibanze, ariko tekinoroji ya desulfurizasi y’ibinyabuzima ntabwo ikuze muri iki gihe.

Tekinoroji yumye ikubiyemo uburyo bwa oxyde oxyde, uburyo bwa karubone bukoreshwa, uburyo bwa sikeli ya molekile, uburyo bwo guhanahana ion, uburyo bwo gutandukanya membrane, uburyo bwa biohimiki, nibindi, muri iki gihe, tekinoroji yumye ya PSA niyo ikoreshwa cyane mubikorwa bito bito bito byangiza gaze munganda, bigenzurwa na mudasobwa byuzuye, bikora byikora, ndetse no kuvanaho umunara wigihe kirekire.

uburyo bwo gusohora

Amorphous fer hydroxide (inzira yumye). Ibiranga: ifite ibiranga desulfurizasi yuzuye, ubushobozi bwa sulfure nyinshi, imbaraga nziza kandi zititabwaho. Ikoreshwa cyane mugukuraho hydrogen sulfide muri gaze gasanzwe, gaze ya sintetike, biyogazi, gaze yamakara, metani yamakara hamwe nibikoresho bitandukanye birimo sulfuru; Amorphous hydroxyl oxidation desulfurisation ni reaction desulfurizasiyo, idashobora kugenzura ubujyakuzimu. Ninzira nziza ya desulfurizasiyo. Hamwe no kuzura desulfurizeri no kwinjira mu munara wa desulfurizasi, ingaruka ya desulfurizasi izagabanuka cyane, kandi ibirimo hydrogène sulfide muri gaze gasukuye izamuka cyane, bityo rero birakenewe gusimbuza desulfurizeri mugihe.
