Iingenelo zeeSeti zeJeneretha zeMethanol

Iiseti zejenereyitha ye-Methanol, njengetekhnoloji entsha yokuvelisa umbane, zibonisa iingenelo ezibalulekileyo kwiimeko ezithile nakwinguqu yamandla yexesha elizayo. Amandla azo aphambili akwiindawo ezine: ukuba nobuhlobo nokusingqongileyo, ukuguquguquka kwepetroli, ukhuseleko olucwangcisiweyo, kunye nokusebenziseka lula.

Nantsi inkcazelo eneenkcukacha ngeenzuzo eziphambili ze-methanoliiseti zejenereyitha:

I. Iingenelo eziphambili

1. Iimpawu eziBalaseleyo zeNdalo
   • Amandla angaphantsi kweKhabhoni/eKhabhoni: I-Methanol (CH₃OH) ineathom enye yekhabhoni, kwaye ukutsha kwayo kuvelisa ikhabhoni diokside (CO₂) encinci kakhulu kunedizili (eneeathom zekhabhoni ezingama-~13). Ukuba kusetyenziswa "i-methanol eluhlaza" eyenziwe kwi-hydrogen eluhlaza (eveliswa nge-electrolysis kusetyenziswa amandla ahlaziyekayo) kwaye i-CO₂ ebanjiweyo, umjikelo wokukhupha ikhabhoni ophantse ube yi-zero unokufezekiswa.
   • Ukukhutshwa kokungcola okuphantsi: Xa kuthelekiswa neejenereyitha zedizili, i-methanol iyatshisa icocekile, ayivelisi phantse ii-sulfur oxides (SOx) kunye ne-particle matter (PM - soot). Ukukhutshwa kokungcola kwe-nitrogen oxides (NOx) nako kuphantsi kakhulu. Oku kuyenza ibe luncedo kakhulu kwiindawo ezinolawulo olungqongqo lokukhutshwa kokungcola (umz., ngaphakathi, kumazibuko, kwiindawo zokugcina indalo).
2. Imithombo yepetroli ebanzi kunye nokuguquguquka
   • Iindlela Ezininzi Zokuvelisa: I-Methanol ingaveliswa ngamafutha efosili (igesi yendalo, amalahle), i-biomass gasification (i-bio-methanol), okanye ngokwenziwa kwe-"green hydrogen + i-CO₂ ebanjiweyo" (i-green methanol), enika imithombo eyahlukeneyo yokutya.
   • Ibhulorho yoTshintsho lwaMandla: Kwinqanaba langoku apho amandla ahlaziyekayo esaqhubeka ixesha elide kwaye iziseko zehydrogen zingaphuhliswanga ngokwaneleyo, i-methanol isebenza njengesixhobo esifanelekileyo sokuthwala amafutha okutshintsha ukusuka kwi-fossil fuels ukuya kwi-green energy. Ingaveliswa kusetyenziswa iziseko ze-fossil fuel ezikhoyo ngelixa ivula indlela ye-methanol eluhlaza yexesha elizayo.
3. Ukhuseleko Oluphezulu kunye Nokulula Kokugcina Nokuthuthwa
   • Ulwelo Kwiimeko Ezingqongileyo: Olu lolona ncedo lwayo lukhulu kuneegesi ezifana ne-hydrogen kunye negesi yendalo. I-Methanol lulwelo olukwiqondo lobushushu begumbi kunye noxinzelelo, aludingi kugcinwa koxinzelelo oluphezulu okanye olungenabungozi. Ingasebenzisa ngokuthe ngqo okanye ifake ngokutsha ngokulula iitanki zokugcina ipetroli/idizili ezikhoyo, iilori zetanki, kunye neziseko zokugcwalisa ipetroli, nto leyo ekhokelela kwiindleko zokugcina nezokuthutha eziphantsi kakhulu kunye nemiqobo yobugcisa.
   • Ukhuseleko Oluphezulu: Nangona i-methanol inetyhefu kwaye itsha, imeko yayo yolwelo yenza kube lula ukuyilawula nokuyilawula xa kuthelekiswa neegesi ezifana negesi yendalo (eqhumayo), i-hydrogen (eqhumayo, enokuvuza), okanye i-ammonia (enetyhefu), nto leyo eyenza kube lula ukuyiphatha.
4. Ubuchwepheshe Obuvuthiweyo kunye Nokulungela Ukubuyela Kwimo Entsha
   • Ukuhambelana neTekhnoloji yeNjini yokuQhuma ngaphakathi: Iiseti zejenereyitha zedizili ezikhoyo zinokuguqulwa zisebenze kwi-methanol okanye i-methanol-diesel dual fuel ngokutshintsha okulula (umz., ukutshintsha inkqubo yokufaka ipetroli, ukulungisa i-ECU, ukuphucula izinto ezimelana nokugqwala). Ixabiso lokuguqula liphantsi kakhulu kunokuphuhlisa inkqubo yamandla entsha ngokupheleleyo.
   • Amandla Okurhweba Akhawulezileyo: Ukusebenzisa uthotho lweshishini leenjini zokutsha zangaphakathi ezivuthiweyo, umjikelo we-R&D kunye nowemveliso yobuninzi kwiijenereyitha ze-methanol unokuba mfutshane, okuvumela ukusasazwa ngokukhawuleza kwimarike.

II. Iingenelo kwiMiba yoSetyenziso

• Amandla Olwandle: Njengoko i-International Maritime Organisation (IMO) ikhuthaza ukuba kususwe iicarbonization, i-methanol eluhlaza ibonwa njengepetroli ebalulekileyo yolwandle kwixesha elizayo, idala imakethi enkulu yeejenereyitha/iinkqubo zamandla ze-methanol yolwandle.
• Amandla Angaphandle kweGridi kunye ne-Backup: Kwiimeko ezifuna amandla okugcina athembekileyo afana nemigodi, iindawo ezikude, kunye namaziko edatha, ukulula kokugcina/ukuthutha kwe-methanol kunye nozinzo oluphezulu kuyenza ibe sisisombululo samandla angaphandle kwegridi esicocekileyo.
• Ukucheba kunye nokugcina amandla avuselelekayo: Umbane ovuselelekayo ongaphezulu ungaguqulwa ube yi-methanol eluhlaza ukuze igcinwe (“Amandla-ukuya-ku-Ulwelo”), enokusetyenziswa ukuvelisa amandla azinzileyo ngeejenereyitha ze-methanol xa kufuneka. Oku kusombulula ingxaki yexeshana ye-renewables kwaye sisisombululo esihle sokugcina amandla ixesha elide.
• Amandla ahambayo kunye neeNdawo eziKhethekileyo: Kwiimeko ezichaphazeleka kakhulu kukukhutshwa kwegesi efana nemisebenzi yangaphakathi okanye uhlangulo olungxamisekileyo, iiyunithi ze-methanol ezinokukhutshwa kwegesi okuncinci zifanelekile ngakumbi.

III. Imingeni ekufuneka iqwalaselwe (Ukuze igqibelele)

• Uxinano Lwamandla Aphantsi: Uxinano lwamandla e-Methanol lumalunga nesiqingatha soxinano lwedizili, oko kuthetha ukuba kufuneka itanki enkulu yamafutha ukuze kuphume amandla afanayo.
• Ubuthi: I-Methanol iyingozi ebantwini kwaye ifuna ulawulo olungqongqo ukuze kuthintelwe ukuginywa okanye ukudibana nolusu ixesha elide.
• Ukuhambelana kwezinto: I-Methanol iyabola kwiirabha ezithile, iiplastiki, kunye neentsimbi (umz., i-aluminium, i-zinc), nto leyo efuna ukuba kukhethwe izinto ezihambelanayo.
• Iziseko zophuhliso kunye neendleko: Okwangoku, imveliso ye-methanol eluhlaza incinci kwaye ibiza kakhulu, kwaye inethiwekhi yokuzalisa amafutha ayikamiselwa ngokupheleleyo. Nangona kunjalo, uhlobo lwayo lolwelo lwenza uphuhliso lweziseko zophuhliso lube lula kakhulu kune-hydrogen.
• Iingxaki Zokuqala Ngobandayo: I-methanol ecocekileyo ayinawo umphunga ofanelekileyo kumaqondo obushushu aphantsi, nto leyo enokubangela iingxaki zokuqalisa ngobushushu, edla ngokufuna amanyathelo ancedisayo (umz., ukufudumeza kwangaphambili, ukuxuba nedizili encinci).

Isishwankathelo

Inzuzo ephambili yeeseti zejenereyitha ye-methanol ikukudibanisa indawo yokugcina/yokuthutha ipetroli engamanzi kunye namandla okusingqongileyo epetroli eluhlaza yexesha elizayo. Yiteknoloji esebenzayo yokudibanisa amandla emveli kunye neenkqubo zamandla ezivuselelekayo zehydrogen/eziphinda zisetyenziswe kwixesha elizayo.

Ifanelekile ngokukodwa njengendlela ecocekileyo yokuthatha indawoiijenereyitha zedizilikwiimeko ezineemfuno eziphezulu zokusingqongileyo, ukuxhomekeka kakhulu ekugcinweni/ekuthuthweni lula, kunye nokufikelela kwiindlela zokubonelela nge-methanol. Iingenelo zayo ziya kubonakala ngakumbi njengoko ishishini le-methanol eluhlaza likhula kwaye iindleko ziyancipha.
