Ibyiza by'ibikoresho bya Methanol Generator

Imashini zitanga amashanyarazi za Methanol, nk'ikoranabuhanga rishya rigezweho mu kubyaza umusaruro ingufu, zigaragaza inyungu zikomeye mu bihe runaka no mu mpinduka z'ingufu mu gihe kizaza. Imbaraga zazo z'ingenzi zikubiye ahanini mu bintu bine: kubungabunga ibidukikije, koroshya lisansi, umutekano mu by'ingenzi, no koroshya ikoreshwa ryayo.

Dore isesengura rirambuye ry'ibyiza by'ingenzi bya methanolamaseti ya moteri:

I. Ibyiza by'ingenzi

1. Imiterere myiza y'ibidukikije
   • Ubushobozi bwo kutagira karuboni nkeya / karuboni: Methanol (CH₃OH) irimo atome imwe ya karuboni, kandi gutwika kwayo gutanga dioxyde de carbone (CO₂) nkeya cyane ugereranyije na mazutu (ifite atome za karuboni ~13). Iyo "methanol y'icyatsi" ikozwe muri hydrogen y'icyatsi (ikorwa hifashishijwe electrolysis ikoresheje ingufu zishobora kuvugururwa) igakoreshwa na CO₂, uruziga rwo gusohora karuboni hafi ya zeru rushobora kugerwaho.
   • Imyuka ihumanya ikirere mike: Ugereranije n’imashini zitanga mazutu, methanol itunganya isuku, hafi ya yose nta sulfure oxydes (SOx) na particulate matter (PM - soot). Imyuka ihumanya ikirere ya azote oxydes (NOx) nayo iri hasi cyane. Ibi bituma igira akamaro cyane mu turere dufite uburyo bukomeye bwo kugenzura imyuka ihumanya ikirere (urugero, mu nzu, ku byambu, mu bidukikije).
2. Isoko rinini rya lisansi n'uburyo bworoshye bwo guhindura imiterere y'ibikomoka kuri lisansi
   • Inzira nyinshi zo gukora: Methanol ishobora gukorwa mu bikomoka kuri peteroli (gaze karemano, amakara), imyuka ikomoka kuri biomass (bio-methanol), cyangwa binyuze mu gukora ikomoka kuri "hydrogen y'icyatsi kibisi + CO₂ yafashwe" (methanol y'icyatsi kibisi), itanga amasoko atandukanye y'ibiribwa.
   • Inzira y'Ingufu: Muri iki gihe aho ingufu zishobora kuvugururwa zikiri mu bihe bitandukanye kandi ibikorwa remezo bya hydrogen bikaba bidatera imbere, methanol ikora nk'amavuta meza yo gutwara lisansi yo kuva kuri lisansi ijya kuri lisansi isanzwe. Ishobora gukorwa hakoreshejwe ibikorwa remezo bya lisansi isanzweho mu gihe hazabaho lisansi isanzwe mu gihe kizaza.
3. Umutekano wo hejuru no koroshya kubika no gutwara
   • Amazi ari mu bihe biri hagati: Iyi ni yo nyungu yayo ikomeye kurusha imyuka nka hydrogen na gaze karemano. Methanol ni amazi ari mu bushyuhe bw'icyumba n'umuvuduko, nta gipimo cy'umuvuduko mwinshi cyangwa cryogenic kibikwa. Ishobora gukoresha cyangwa kongera gushyira mu buryo bworoshye ibigega bya lisansi/mazutu bihari, amakamyo y'amatafari, n'ibikorwa remezo byo kongeramo lisansi, bigatuma ikiguzi cyo kubika no gutwara ibintu gigabanuka cyane ndetse n'imbogamizi za tekiniki.
   • Umutekano Ukabije: Nubwo methanol ari uburozi kandi ishobora gushya, imiterere yayo y'amazi ituma amazi asohoka byoroha kuyagenzura no kuyacunga ugereranije n'imyuka nka gaze karemano (ishobora guturika), hydrogen (ishobora guturika, ishobora gusohoka), cyangwa ammonia (ishobora guturika), bigatuma umutekano wayo woroha kuyitwara.
4. Ikoranabuhanga Rikuze n'Uburyo bworoshye bwo kuvugurura
   • Ikorana n'ikoranabuhanga rya moteri zikoresha umuriro: Imashini zikoresha mazutu zisanzwe zishobora guhindurwa kugira ngo zikoreshwe kuri methanol cyangwa methanol-diesel ebyiri binyuze mu guhindura ibintu byoroshye (urugero, gusimbuza sisitemu yo gutera lisansi, guhindura ECU, kongera ibikoresho birwanya ingese). Igiciro cyo guhindura ni gito cyane ugereranije no guteza imbere sisitemu nshya y'ingufu.
   • Ingufu zihuse zo Gucuruza: Gukoresha uruhererekane rw'inganda zikoresha moteri zitwika imbere mu buryo bugezweho, ubushakashatsi n'iterambere n'umusaruro mwinshi w'imashini zitanga methanol bishobora kuba bigufi, bigatuma isoko rikwirakwizwa vuba.

II. Ibyiza mu miterere y'ikoreshwa

• Ingufu zo mu mazi: Mu gihe Umuryango Mpuzamahanga wita ku Butaka (IMO) uharanira ko habaho gukuraho karuboni, methanol y’icyatsi kibisi ifatwa nk’ingenzi mu bizaza by’amazi yo mu mazi, bigatuma habaho isoko rinini ry’imashini zitanga methanol zo mu mazi/sisteme z’ingufu.
• Ingufu zo Kubika no Gusubiza Ingufu mu Muyoboro Utari ku Rukuta n'Ingufu zo Kubika: Mu bihe bisaba ingufu zizewe zo kubika nk'ibirombe, ahantu kure, n'amakuru, uburyo bworoshye bwo kubika/gutwara methanol hamwe n'uburyo ihagaze neza bituma iba igisubizo cy'ingufu zisukuye zidafite urukuta.
• Ingufu zisubira zo kogosha no kubika: Amashanyarazi arenze ashobora guhindurwamo methanol y’icyatsi kibisi yo kubika ("Power-to-Liquid"), hanyuma agakoreshwa mu gutanga ingufu zihamye binyuze mu imashini zitanga methanol iyo bikenewe. Ibi bikemura ikibazo cy’ingufu zisubira kandi ni igisubizo cyiza cyo kubika ingufu igihe kirekire.
• Ingufu zigendanwa n'ibigo byihariye: Mu bidukikije bishobora kwangiza imyuka ihumanya ikirere nko mu ngo cyangwa ubutabazi bwihutirwa, ibikoresho bya methanol bigabanya imyuka ihumanya ikirere birakwiriye cyane.

III. Imbogamizi zo gutekerezaho (kugira ngo buzure)

• Ubucucike bw'ingufu nke: Ubucucike bw'ingufu za Methanol ni kimwe cya kabiri cy'iza mazutu, bivuze ko hakenewe ikigega kinini cya lisansi kugira ngo ingufu zingana.
• Uburozi: Methanol ni uburozi ku bantu kandi isaba gucungwa neza kugira ngo hirindwe ko yanywa cyangwa ngo ikore ku ruhu igihe kirekire.
• Ubushobozi bw'ibikoresho: Methanol irangirika ku byuma bimwe na bimwe bya rabu, plastiki, n'ibyuma (urugero: aluminiyumu, zinki), bisaba guhitamo ibikoresho bihuye.
• Ibikorwaremezo n'Ikiguzi: Muri iki gihe, umusaruro wa methanol y’icyatsi kibisi ni muto kandi uhenze, kandi umuyoboro wo kongeramo lisansi nturamenyekana neza. Ariko, imiterere yayo y’amazi ituma iterambere ry’ibikorwaremezo ryoroha cyane kurusha hydrogen.
• Ibibazo byo Gutangira mu Bukonje: Methanol nziza ifite umwuka mubi mu bushyuhe buri hasi, ibi bikaba bishobora gutera ibibazo byo gutangira mu Bukonje, akenshi bigasaba ingamba z'inyongera (urugero: gushyushya mbere, kuvanga n'ingano nto ya mazutu).

Incamake

Akamaro k'ingenzi k'ibikoresho bya moteri ya methanol ni uguhuza uburyo bwo kubika/gutwara lisansi y'amazi n'ubushobozi bwo kurengera ibidukikije bw'ibikomoka ku bimera mu gihe kizaza. Ni ikoranabuhanga rifatika rihuza ingufu zisanzwe na sisitemu z'ingufu zikomoka kuri hydrogen/ingufu zishobora kongera gukoreshwa mu gihe kizaza.

Birakwiriye cyane nk'uburyo busukuye bwo gusimburamoteri zikoresha mazutumu bihe bifite ibisabwa byinshi ku bidukikije, kwishingikiriza cyane ku buryo bworohereza ububiko/ubwikorezi, no kubona imiyoboro ya methanol. Ibyiza byayo bizarushaho kugaragara uko inganda za methanol zikomeza gukura n'ibiciro bikagabanuka.
