Irhasi yeNdalo ukuya kwiplanti yokucoca iMethanol

Izinto eziluhlaza zokuvelisa i-methanol zinokuba yigesi yendalo, igesi ye-oven ye-coke, amalahle, i-oyile eshiyekileyo, i-naphtha, i-acetylene tail gas okanye enye i-gas yenkunkuma equkethe i-hydrogen kunye ne-carbon monoxide.Ukusukela ngeminyaka yoo-1950s, irhasi yendalo ngokuthe ngcembe iye yaba yeyona nto iphambili kwimveliso yemethanol.Okwangoku, ngaphezu kwe-90% yezityalo ezisehlabathini zisebenzisa igesi yendalo njengemathiriyeli ekrwada.Ngenxa yokuba inkqubo yokuvelisa i-methanol kwigesi yendalo imfutshane, utyalo-mali luphantsi, ixabiso lemveliso liphantsi, kwaye ukukhutshwa kwenkunkuma emithathu kuncinci.Ngamandla acocekileyo afanele akhuthazwe ngamandla.

● Ukonga umbane kunye nokonga utyalo-mali.
● Uhlobo olutsha lwe-methanol synthesis tower ene-by-product medium pressure steam yamkelwa ukunciphisa ukusetyenziswa kwamandla.
● Ukuhlanganiswa kwezixhobo eziphezulu, umthwalo omncinci wokusebenza kwisiza kunye nexesha elifutshane lokwakha.
● Itekhnoloji yokonga amandla, njengeteknoloji yokubuyisela i-hydrogen, iteknoloji yokuguqulwa kwangaphambili, iteknoloji yokugcwalisa igesi yendalo kunye nobuchwepheshe bokutshisa umoya ovuthayo, bamkelwe ukunciphisa ukusetyenziswa kwemethanol.Ngamanyathelo ahlukeneyo, ukusetyenziswa kwamandla ngetoni ye-methanol kuncitshiswa ukusuka kwi-38 ~ 40 GJ ukuya kwi-29 ~ 33 GJ.

Irhasi yendalo isetyenziswa njengento ekrwada, emva koko icinezelwe, idityanisiwe kwaye ihlanjululwe ukuvelisa i-syngas (ikakhulu iqulunqwe yi-H2 kunye ne-CO).Emva koxinzelelo olongezelelweyo, i-syngas ingena kwi-methanol synthesis tower ukuze idibanise i-methanol phantsi kwesenzo se-catalyst.Emva kokudityaniswa kwe-methanol ekrwada, nge-predistillation yangaphambili ukususa i-fusel, ukulungiswa ukufumana imethanol egqityiweyo.
