N-hexane mmepụta usoro
Ọtụtụ n'ime mmepụta hexane si mba ọzọ na-eji usoro mgbasa ozi sieve molecular, dị ka Richfielcd (Richfield) na Watson (Watson) na United States, na-eji raffinate emegharịrị dị ka akụrụngwa, site na-emegharị akwa abụọ ma ọ bụ karịa maka mgbasa ozi. Pịa desorption iji mepụta n-hexane.
Ọtụtụ ndị na-emepụta hexane ụlọ na-eji usoro distillation hydrogenation, nke kewara n'ime ụdị abụọ:

Nke mbụ, hydrogenation na-emezigharị.

A makwaara dị ka pre-hydrogenation, akụrụngwa na-ekpo ọkụ site na mgbanwe okpomọkụ, na-erute mmeghachi omume okpomọkụ, na-abanye na reactor hydrogenation, desulfurization na dearomatization mmeghachi omume n'okpuru omume nke catalyst, ihe mgbaze mmanụ na hydrogen ngwakọta na-abanye na nkewa tank maka nkewa. , hydrogen mgbake, ihe mgbaze mmanụ n'ime fractionation ụlọ elu Bee n'ime okokụre ngwaahịa. N'ikwu okwu n'ozuzu, mgbe hydrogenation nke akụrụngwa, ọ ka na-ekewa ma bee n'ime n-hexane, na ụdị mmanụ mgbaze ndị ọzọ. Uru ya bụ na akụrụngwa niile na-emebi emebi ma mebie ya, na-eji ngwaahịa ọ bụla eme ihe n'ụzọ zuru oke. Ihe ọghọm bụ na ntinye ego buru ibu na ihe oriri na-eri ihe dị elu.

Nke abụọ, mmezi mgbe ahụ hydrogenation.

A na-akpọkwa ya dị ka post-hydrogenation, n'ihe banyere n-hexane, a na-ebu ụzọ bepụ ihe ọkụkụ ahụ n'ime hexane crude nke 66-69 distillation nso, ịdị ọcha nke hexane crude na-akawanye mma, na ebe ọ bụ na otu phenyl dị. dị na n-hexane, hexane na hexane crude A na-abawanye ọdịnaya nke ukwuu, wee tinye ya na hydrodebenzene desulfurization iji mepụta n-hexane dị elu. Ihe bara uru bụ na ntinye ego ahụ dị ntakịrị na ihe eji eme ihe dị ntakịrị. Ọdịmma ya bụ na a naghị eji akụkụ ahụ na-adịghị mmiri mmiri eme ihe nke ọma.
