Igesi Yemvelo eya embonini yokuhluza iMethanol

Izinto zokusetshenziswa zokukhiqiza i-methanol kungaba igesi yemvelo, igesi ye-coke oven, amalahle, uwoyela osalayo, i-naphtha, i-acetylene tail gas noma enye igesi yemfucuza equkethe i-hydrogen ne-carbon monoxide.Kusukela ngeminyaka yawo-1950, igesi yemvelo kancane kancane isiphenduke into eyinhloko yokwenziwa kwe-methanol.Njengamanje, izitshalo ezingaphezu kuka-90% emhlabeni zisebenzisa igesi yemvelo njengempahla eluhlaza.Ngenxa yokuthi ukugeleza kwenqubo yokukhiqizwa kwe-methanol kusuka kugesi yemvelo kufushane, ukutshalwa kwezimali kuncane, izindleko zokukhiqiza ziphansi, futhi ukukhishwa kwemfucuza emithathu kuncane.Ungamandla ahlanzekile okufanele akhuthazwe ngamandla.

● Ukonga amandla nokonga utshalomali.
● Uhlobo olusha lombhoshongo we-methanol synthesis one-by-product medium pressure steam kwamukelwa ukuze kwehliswe ukusetshenziswa kwamandla.
● Ukuhlanganiswa kwemishini ephezulu, umthwalo omncane wokusebenza esizeni kanye nesikhathi sokwakha esifushane.
● Ubuchwepheshe bokonga amandla, obufana nobuchwepheshe bokutholwa kwe-hydrogen, ubuchwepheshe bangaphambi kokuguqulwa, ubuchwepheshe bokugcwala kwegesi yemvelo kanye nobuchwepheshe bokushisa komoya okushisa, kwamukelwa ukuze kwehliswe ukusetshenziswa kwe-methanol.Ngezinyathelo ezihlukahlukene, ukusetshenziswa kwamandla ngethani ngalinye le-methanol kuncipha ukusuka ku-38 ~ 40 GJ kuya ku-29 ~ 33 GJ.

Igesi yemvelo isetshenziswa njengempahla eluhlaza, bese icindezelwa, ikhishwe yi-desulfurized futhi ihlanzwe ukuze kukhiqizwe ama-syngas (ikakhulukazi akhiwe i-H2 ne-CO).Ngemuva kokucindezelwa okwengeziwe, i-syngas ingena embhoshongweni we-methanol synthesis ukuze ihlanganise i-methanol ngaphansi kwesenzo se-catalyst.Ngemva kokuhlanganiswa kwe-methanol engahluziwe, ngokusebenzisa i-pre distillation ukuze kukhishwe i-fusel, ukulungiswa ukuze kutholwe i-methanol eqediwe.
