Ishami rishinzwe gutunganya lisansi ya hydrogen sulfide

Intangiriro

Mu iterambere ry’umuryango wacu, dushyigikira ingufu zisukuye, bityo icyifuzo cya gaze karemano nk’ingufu zisukuye nacyo kiriyongera. Ariko, mu gihe cyo gukoresha gaze karemano, amariba menshi ya gaze akunze kuba arimo hydrogen sulfide, itera ingese ku bikoresho n’imiyoboro, ihumanya ibidukikije kandi ikabangamira ubuzima bw’abantu. Mu iterambere rya siyansi n’ikoranabuhanga, ikoreshwa ryagutse ry’ikoranabuhanga ryo gukuraho gazi karemano ryakemuye ibi bibazo, ariko icyarimwe, ikiguzi cyo gutunganya no gutunganya gaze karemano cyariyongereye.

Ihame

Kugabanya ubushyuhe mu buryo bwa molekile (bitwa kandi desulfurization) skid, nanone yitwa molecular sieve sweeting skid, ni igikoresho cy'ingenzi mu mushinga wo gutunganya gaze karemano cyangwa ikoranabuhanga rya gaze karemano.

Urusenda rwa molekuli ni kristu ya aluminiyumu ifite icyuma cya alkali ifite imiterere y'amagufwa n'imiterere imwe y'imiyoboro mito. Ni urusenda rufite imikorere myiza cyane, ubushobozi bwo kuvoma cyane no guhitamo kuvoma neza. Ubwa mbere, hari inzira nyinshi zifite ingano imwe y'imiyoboro n'imyobo iteguye neza mu miterere y'urusenda rwa molekuli, bidatanga ubuso bunini cyane gusa, ahubwo binagabanya kwinjira kwa molekuli nini kurusha imyobo; Icya kabiri, ubuso bw'urusenda rwa molekuli bufite polarity nyinshi bitewe n'imiterere ya lattice ya ionic, bityo rufite ubushobozi bwo kuvoma bwinshi bwa molekuli zidafite amazi, molekuli za polar na molekuli zishobora gushwanyagurika. Amazi na sulfide ya hydrogen ni molekuli za polar, kandi umurambararo wa molekuli ni muto ugereranije n'umurambararo w'urusenda rwa molekuli. Iyo gazi mbisi irimo amazi make inyuze mu gasanduku k'urusenda rwa molekuli ku bushyuhe bw'icyumba, amazi make na sulfide ya hydrogen birashongeshwa, bityo, ingano y'amazi na sulfide ya hydrogen mu mwuka w'ibiribwa iragabanuka, kandi intego yo kubura amazi no kugabanya sulfure iragerwaho. Uburyo bwo kuvoma mu ruziga rw’ibinyabutabire birimo kuzura mu miyoboro y’amazi no kuzura mu buryo bufatika bitewe n’imbaraga za van der Waals. Dukurikije ikigereranyo cya Kelvin, kuzura mu miyoboro y’amazi bigabanuka uko ubushyuhe bwiyongera, mu gihe kuzura mu miyoboro y’amazi ari inzira yo mu kirere, kandi kuzura kwayo bigabanuka uko ubushyuhe bwiyongera kandi bikiyongera uko umuvuduko wiyongera; Kubwibyo, uburyo bwo kuzura mu ruziga rw’ibinyabutabire busanzwe bukorwa ku bushyuhe buke n’umuvuduko mwinshi, mu gihe kuvugurura mu buryo bw’isesengura bikorwa ku bushyuhe bwinshi n’umuvuduko muke. Mu gihe cy’ubushyuhe bwinshi, umwuka wo kuvugurura mu miyoboro usukuye kandi muke, uruziga rw’ibinyabutabire rurekura adsorbate iri muri mikoro mu ruziga rw’ibinyabutabire kugeza igihe ingano y’adsorbate iri mu ruziga igeze ku rwego rwo hasi cyane. Ifite kandi ubushobozi bwo kuvoma amazi na hydrogen sulfide bivuye mu gazi ikoreshwa mu ruziga, bigatuma ruziga rusubiramo kandi rukongera gukoreshwa.

Inzira y'ikoranabuhanga

Urujya n'uruza rw'ibikorwa rugaragara ku gishushanyo. Iki gikoresho gikoresha inzira eshatu z'iminara, umunara umwe wo gukurura, umunara umwe wo kuvugurura n'umunara umwe wo gukonjesha. Iyo umwuka w'ibiryo winjiye muri icyo gikoresho, ubushyuhe bwa gazi y'ibiryo bugabanuka bitewe n'icyuma gikonjesha mbere y'uko gikonjesha, hanyuma amazi yigenga agakurwaho n'icyuma gitandukanya amazi, hanyuma akinjira mu muyoboro wa molekile wo gusukura sulfurization a-801, a-802 na a-803. Amazi na sulfure ya hydrogen mu mwuka w'ibiryo by ...

Urusenda rwa molekile rukeneye kuvugururwa nyuma yo guhumeka amazi na sulfide ya hidrojeni. Igice kimwe cya gaze y’ibicuruzwa gikurwa muri gaze y’ibicuruzwa nyuma yo kuyungurura ivumbi nk’umwuka wo kuvugurura. Iyo gaze imaze gushyuha kugeza kuri 270 ℃ mu itanura rishyushya, umunara ushyuha buhoro buhoro kugeza kuri 270 ℃ kuva hejuru kugeza hasi unyuze mu munara wa molekile wo gusukura sulfurization warangije inzira yo guhumeka, kugira ngo amazi na sulfide ya hidrojeni byinjijwe kuri urusenda rwa molekile bishobore guhindurwamo gaze yo kuvugurura ikungahaye kandi birangize inzira yo kuvugurura.

Gazi ikungahaye ku kuvugurura nyuma yo kuva mu munara wo kuvugurura yinjira mu cyuma gikonjesha gaze kugira ngo ikonje kugeza kuri 50°C, maze gaze ikonjeshwa igashyirwa mu cyuma gishyushya umuriro.

Umunara w’uruhererekane rw’ibintu bikonje ugomba gukonjeshwa nyuma yo kongera kuvugururwa. Kugira ngo wongere ugarure neza kandi ukoreshe ingufu z’ubushyuhe, umwuka wo kongera kuvugururwa ubanza gukoreshwa nk’umwuka ukonje uhuha, maze umunara ukonjeshwa ukagera kuri 50°C uhereye hejuru ugana hasi unyuze mu munara w’uruhererekane rw’ibintu bikonje warangije igikorwa cyo kongera kuvugururwa. Muri icyo gihe, ushyushya ubwawo. Nyuma y’uko umwuka ukonje uhuha uvuye mu munara ukonje, winjira mu itanura rishyushya umwuka wo kongera kuvugururwa kugira ngo ushyushye, hanyuma ukongera kuvugururwa umunara w’uruhererekane rw’ibintu bikonje nk’umwuka wo kongera kuvugururwa. Igikoresho gihindura buri masaha 8.
