Gukuraho Gazi Kamere: Gusukura Amavuta yo mu Kiraro
Gazi karemano, "ibikomoka ku mavuta y'ingenzi", akenshi iba irimo hydrogen sulfide (H₂S) n'ibinyabutabire bya sulfure (mercaptans, COS), bihumanya, bikangiza, kandi bigatera SOx yangiza iyo bitwitswe. Bityo rero, gusukura ibiryo (kuryoshya) ni ngombwa.
Ihame:Ihame ry'ingenzi rikubiyemo gutandukanya imvange ya sulfur n'umugezi wa gaze ikungahaye kuri methane hakoreshejwe uburyo bwa shimi cyangwa ubw'umubiri. Ibi bireba urwego rwa H₂S kugeza ku bipimo by'imiyoboro (akenshi ≤ 4 ppmv) na sulfur yose kugira ngo bihuze n'ibipimo ngenderwaho by'ibidukikije/uburyo bwo gutunganya.
Uburyo bw'ingenzi:
- Kunywa Amine (Ibintu bishongesha imiti):Uburyo bwiganjemo. Alkanolamines (urugero, MDEA) ikora mu buryo busubira inyuma hamwe na H₂S na CO₂ mu cyuma gifata umwuka. Amine ikungahaye ivugururwa mu cyuma gikoresha ubushyuhe, irekura imyuka ya aside nyinshi kugira ngo ikomeze gutunganywa (nk'uko Claus unit) hanyuma ikongera gukoresha amine yoroheje.
- Uburyo bwo kwinjiza umuti ukomoka ku binyabutabire (urugero: Selexol, Rectisol):Koresha imiti isukura (nk'ibinyabutabire) ishongesha ibintu bya sulfur mu buryo bufatika mu gihe cy'umuvuduko mwinshi. Ivugururwa ribaho ahanini mu kugabanya umuvuduko (kuvugurura ubwiza bw'izuba), ritanga inyungu ku biryo bifite umuvuduko mwinshi kandi bifite sulfur nyinshi.
- Gushyiramo amazi mu buryo buhamye (urugero, Utuzingo twa Molekile, Okiside ya Zinki):Ikoreshwa mu gusiga irangi ryimbitse kugeza ku rugero ruto cyane rwa ppm/ppb cyangwa gukuraho ibintu byinshi mu bihe runaka. Ibikoresho bikuramo ibintu bya sulfure ku buso bwabyo; kongera kuvugurura bisaba gushyushya cyangwa gusimbuza.
- Inzira ya Claus:Ntabwo ari uburyo bwo kongerera ubushyuhe mu buryo butaziguye, ahubwo ni ingenzi mu kuvura imyuka ikomoka kuri asidebyakozwebikozwe mu bice bya amine. Bihindura H₂S mo sulfur y’ibanze binyuze mu gutwika igice kimwe no gukora catalytic (2H₂S + O₂ → S₂ + 2H₂O).
Ibyiza:
- Umutekano:Bikuraho ibyago by'uburozi bwa H₂S.
- Kurinda Umutungo:Birinda ingese mu miyoboro, mu mavali, no mu bikoresho byo gutunganya.
- Iyubahirizwa ry'amategeko agenga ibidukikije:Bituma habaho gutwika neza, bigabanya imyuka ya SOx n'imvura ya aside.
- Ubwiza bw'Igicuruzwa:Ihuye n'ibipimo by'imiyoboro ya LNG; irinda uburozi bwa catalyst ku bakoresha amazi yo hasi.
- Gusubirana Sulfure:Ikora sulfure y'agaciro.
Ibyiringiro by'ejo hazaza:Bitewe n'amategeko akaze agenga ibidukikije ndetse n'izamuka rya LNG, icyifuzo cyo gukuramo sulfur mu buryo bunoze kiriyongera. Ibigomba kwibandwaho mu gihe kizaza birimo:
- Ibikoresho bigezweho byo gushonga:Ibinyabutabire bivanze bihuza imiterere y'ibinyabutabire n'iy'umubiri kugira ngo bigire ubushobozi bwo guhitamo neza no kugabanya ikoreshwa ry'ingufu.
- Ikoranabuhanga rya Membrane:Bisezeranya gutandukanya ingufu mu buryo bukoresha uburyo butandukanye, cyane cyane mu gukuraho ingufu nyinshi cyangwa imiyoboro yihariye.
- Gukomeza ibikorwa:Guteza imbere uburyo bwo guhuza hagati y’ibikoresho byo kugarura, kuvugurura, no kugarura sulfure.
- Uburyo bwo gukoresha ikoranabuhanga mu binyabuzima:Gusuzuma uburyo bwo gukuraho sulfur mu binyabuzima kugira ngo habeho ikoreshwa ryihariye.
Gukuraho gazi karemano biracyari ikoranabuhanga ry’ingenzi, rituma uyu musaruro w’ingufu w’ingenzi ukoreshwa neza, mu buryo bwizewe, kandi bunoze, hamwe n’udushya duhoraho dufasha ahazaza hawo.
