Uburyo bwo gusukura sulphurization ya molekile

Ihame

Uburyo bwo gusukura gazi mu buryo bwa molecular sieve (desulfurization), buzwi kandi nka molecular sieve sweeting skid, ni igikoresho cy'ingenzi mu gusukura gazi karemano cyangwa imiterere ya gaze karemano. Uburyo bwo gusukura gazi mu buryo bwa molecular ni kristalo ya aluminosilicate y'icyuma ifite imiterere y'umuyoboro n'imiterere imwe ya microporous. Iyo gazi irimo amazi make inyura mu mwanya wa molekile ku bushyuhe bw'icyumba, amazi make na mercaptan biracengerwa, bityo bigabanyiriza amazi na mercaptan mu mwuka w'ibiribwa, bigashyira mu bikorwa intego yo kubura amazi no gusukura gazi. Uburyo bwo gusukura gazi mu buryo bwa molecular sieve burimo gushonga kwa capillary na adsorption iterwa n'imbaraga za van der Waals. Dukurikije ikigereranyo cya Kelvin, bigaragara ko gushonga kwa capillary kugabanuka uko ubushyuhe bwiyongera, mu gihe adsorption ifatika ari inzira yo mu kirere, kandi adsorption yayo igabanuka uko ubushyuhe bwiyongera kandi ikiyongera uko umuvuduko wiyongera; bityo, uburyo bwo gusukura gazi mu buryo bwa molecular sieve bukunze gukorwa ku bushyuhe buke n'umuvuduko mwinshi, mu gihe desorption regeneration ikorwa ku bushyuhe bwinshi n'umuvuduko muto. Mu gihe cy’ubushyuhe bwinshi, umwuka wongera kuvugurura, isukuye kandi ufite umuvuduko muto, umuyoboro wa molekile urekura umuyoboro uri muri mikorobe mu muyoboro wa molekile kugeza igihe ingano y’umuyoboro uri muri molekile igeze ku rwego rwo hasi cyane, kandi ikaba ifite ubushobozi bwo kwinjiza amazi na mercaptan mu mwuka uryohereza, bigatuma habaho uburyo bwo kongera kuvugurura no kongera gukoresha molekile.

Inzira y'ikoranabuhanga

Uburyo bwo gukuraho gazi karemano mu gice cyo gukuraho sulphurization (desulfurization) bugaragara ku ishusho. Iki gice gikoresha inzira eshatu z'iminara, imwe yo kuvoma ndende, imwe yo kuvugurura ndende n'indi yo gukonjesha ndende. Nyuma yo gukuraho amazi ya hydrocarbon anyuze mu gikoresho cyo gutandukanya icyuma gitunganya gazi, gazi yo kugaburira yinjira mu gice cyo gukuraho sulphurization. Amazi na mercaptan biri mu gazi yo kugaburira binyuzwa mu gice cyo gukuraho sulphurization kugira ngo amazi agere ku mazi n'inzira yo kuvoma mercaptan. Gazi isukuye iva mu mazi abira no gukuraho mercaptan yinjira mu cyuma gitunganya gazi kugira ngo ikureho ivumbi rya silika, hanyuma yoherezwa mu mahanga nk'umwuka w'ibicuruzwa.

Uduce twa molekile tugomba kuvugururwa nyuma yo guhumeka amazi na mercaptan runaka. Nyuma yo kuyungurura umukungugu wa gaze y’ibicuruzwa, igice cya gaze y’ibicuruzwa gikurwamo nk’umwuka wo kuvugurura. Iyo gaze imaze gushyushywa kugeza kuri 300 ℃ n’itanura rishyushya, umunara ushyushya buhoro buhoro kugeza kuri 272 ℃ binyuze mu munara wa molekile wo gusukura sulfurization warangije inzira yo guhumeka kuva hasi kugera hejuru, kugira ngo amazi na mercaptan byinjijwe ku ruhu rwa molekile bishobore gutandukanywa kandi bibe gaze yo kuvugurura itunganywa kugira ngo birangize inzira yo kuvugurura ivugurura.
