Uruganda rwo mu rwego rwo hejuru Ubushinwa Uruganda rukora imyuka - Molecular sie desulphurisation skid - Rongteng

Ihame

Molecular sieve desulphurisation (desulfurisation) skid, nanone bita skie ya molekile sivi nziza, ni igikoresho cyingenzi mugusukura gaze karemano cyangwa gutunganya gaze gasanzwe. Amashanyarazi ya molekulari ni alkali icyuma cya aluminosilicate kristal ifite imiterere nuburyo bwa microporome imwe. Iyo gazi y'ibiryo irimo amazi ya trasike inyuze mu buriri bwa molekile ya sikeri ku bushyuhe bw'icyumba, amazi ya trake na mercaptan byinjira, bityo bikagabanya amazi hamwe na mercaptan biri muri gaze y'ibiryo, bikamenya intego yo kubura umwuma no gusohora. Gahunda ya adsorption ya molekile ya molekile ikubiyemo capillary condensation hamwe na adsorption yumubiri iterwa nimbaraga za der der Waals. Duhereye ku kugereranya kwa Kelvin, birashobora kugaragara ko kanseri ya capillary igabanuka hamwe no kwiyongera kwubushyuhe, mugihe adsorption yumubiri ari inzira ya exothermic, kandi adsorption yayo igabanuka hamwe no kwiyongera kwubushyuhe kandi ikiyongera niyongera ryumuvuduko; kubwibyo rero, uburyo bwa adsorption ya sikile ya molekile ikorwa mubushyuhe buke n'umuvuduko mwinshi, mugihe kuvugurura desorption bikorwa mubushyuhe bwinshi n'umuvuduko muke. Mugihe cyubushyuhe bwo hejuru, gazi isukuye kandi yumuvuduko muke, adsorbent ya molekile irekura adsorbate muri micropore mumyuka ya gaze ivugurura kugeza igihe ingano ya adsorbate muri adsorbent igeze kurwego rwo hasi cyane, kandi ifite ubushobozi bwo gukuramo amazi na mercaptan biva mumyuka ya federasiyo, bikamenya uburyo bushya bwo gutunganya no gutunganya ibishishwa bya molekile.

Inzira yikoranabuhanga

Igikorwa cyo gutembera kwa gaze gasanzwe ya molekile sieve desulphurisation (desulfurisation) skid irerekanwa mubishushanyo. Igice gikora inzira eshatu, umunara umwe adsorption, kuvugurura umunara hamwe no gukonjesha umunara. Nyuma yo kuvanaho amazi ya hydrocarubone yashizwemo binyuze mu kugaburira gazi yo kugaburira, gazi yo kugaburira yinjira mu munara wa molekile sie desulfurisation. Amazi na mercaptan muri gazi yo kugaburira byamamajwe na sikeli ya molekile kugirango bamenye inzira yo kubura umwuma na mercaptan adsorption. Gazi isukuye ivuye muri dehidrasi no kuvanaho mercaptan yinjira mubicuruzwa byungurura imyanda ya gaz kugirango ikureho umukungugu wa molekile, hanyuma woherezwa hanze nka gaze yibicuruzwa.

Amashanyarazi ya molekuline agomba kuvugururwa nyuma yo kwamamaza amazi runaka na mercaptan. Nyuma yo kuyungurura umukungugu wibicuruzwa, igice cya gaze yibicuruzwa bivanwa nka gaze nshya. Iyo gaze imaze gushyukwa kugeza kuri 300 ℃ n’itanura rishyushya, umunara ushyushye buhoro kugeza kuri 272 ℃ unyuze mu munara wa molekile sie desulfurisation warangije inzira ya adsorption kuva hasi ukageza hejuru, kugirango amazi na mercaptan byashyizwe kumurongo wa molekile bishobora gutandukana hanyuma bigahinduka gaze yubuzima bushya kugirango irangize inzira nshya.
