Iphrojekthi yokufaka i-2500Nm3/hi-methanol ekukhiqizeni i-hydrogenkanye nedivayisi engu-10000t/a liquid CO2, etholwe yi-TCWY, kuqedwe ngempumelelo. Lolu phiko seluke lwenziwa uphiko olulodwa futhi seluhlangabezane nayo yonke imibandela edingekayo ukuze luqale ukusebenza. I-TCWY iqalise inqubo yabo eyingqayizivele yale yunithi, eqinisekisa ukuthi ukusetshenziswa kwe-methanol ngeyunithi ngayinye kungaphansi kuka-0.5kg methanol/Nm3 hydrogen. Le nqubo ibonakala ngobulula bayo, ukulawula inqubo emfushane, kanye nokusetshenziswa okuqondile kwemikhiqizo ye-H2 kuphrojekthi yekhasimende ye-hydrogen peroxide. Ukwengeza, le nqubo inika amandla ukuthunjwa kwekhabhoni kanye nokukhiqizwa kwe-CO2 ewuketshezi, ngaleyo ndlela ikhulise ukusetshenziswa kwezinsiza.
Uma kuqhathaniswa nezindlela zendabuko zokukhiqiza i-hydrogen, njenge-electrolysis yamanzi,ukulungiswa kwegesi yemvelo, kanye ne-coke coke gasification, inqubo ye-methanol-to-hydrogen inikeza izinzuzo eziningana. Ifaka inqubo elula enesikhathi esifushane sokwakha, edinga ukutshalwa kwezimali okuncane uma kuqhathaniswa. Ngaphezu kwalokho, isebenzisa amandla aphansi futhi ayibangeli noma yikuphi ukungcoliswa kwemvelo. Izinto zokusetshenziswa ezisetshenziswa kule nqubo, ikakhulukazi i-methanol, nazo zingagcinwa futhi zihanjiswe kalula.
Njengoba intuthuko yezinqubo zokukhiqiza i-methanol hydrogen kanye nama-catalysts iqhubeka yenziwa, isikali sokukhiqizwa kwe-methanol hydrogen sikhula kancane kancane. Le ndlela manje isiyisinqumo esikhethwayo sokukhiqiza i-hydrogen encane naphakathi. Ukuthuthukiswa okuqhubekayo kwenqubo kanye nama-catalysts kube nomthelela ekukhuleni kwayo okukhulayo kanye nokusebenza kahle okukhulayo.
Ukuphothulwa ngempumelelo kwephrojekthi yokufaka kanye nokuzuzwa kwezimo zokusebenza kuphawula ingqophamlando ebalulekile ye-TCWY. Ukuzinikela kwabo ekwakheni ikhambi elisimeme nelisebenza kahle ekukhiqizeni i-hydrogen kube nezithelo. Ngokusebenzisa i-methanol njenge-feedstock, i-TCWY ayigcinanga nje ngokuqinisekisa ukukhiqizwa kwe-hydrogen ephumelelayo kodwa futhi iye yabhekana nenkinga yokubanjwa kwekhabhoni nokukhiqizwa kwe-CO2 ewuketshezi, okwenza le nqubo ihambisane nemvelo nakakhulu. Njengoba umhlaba uguqukela ekusaseni elisimeme kakhudlwana, ubuchwepheshe obufana nenqubo ye-methanol-to-hydrogen buzodlala indima ebalulekile ekuqinisekiseni indawo yamandla ehlanzekile neluhlaza. Ukuqaliswa ngempumelelo kwe-TCWY kwale nqubo kubeka isibonelo esihle embonini futhi kukhuthaze ukuhlola okwengeziwe nokwamukelwa kwezinye izindlela zokukhiqiza i-hydrogen.
