Gas sitere na methanol refinery plant

Ngwa maka mmepụta methanol nwere ike ịbụ gas sitere n'okike, coke oven gas, coal, mmanụ fọdụrụ, naphtha, acetylene ọdụ gas ma ọ bụ gas mkpofu ndị ọzọ nwere hydrogen na carbon monoxide.Kemgbe afọ 1950, gas sitere n'okike ejirila nke nta nke nta bụrụ ihe bụ isi maka njikọta methanol.Ka ọ dị ugbu a, ihe karịrị 90% nke ihe ọkụkụ dị n'ụwa na-eji gas eke eme ihe dị ka akụrụngwa.N'ihi na usoro nke mmepụta methanol sitere na gas dị mkpụmkpụ, ntinye ego dị ala, ọnụ ahịa mmepụta dị ala, na nkwụsị nke mkpofu atọ dị ntakịrị.Ọ bụ ume dị ọcha nke kwesịrị ịkwalitesi ike.

● Ịchekwa ume na ịchekwa ego.
● A na-anakwere ụdị ọhụrụ nke methanol synthesis tower nke nwere uzuoku ikuku na-akpata site na ngwaahịa iji belata oriri ike.
● Ngwakọta ngwa ngwa dị elu, obere ọrụ na-arụ ọrụ na saịtị na obere oge ihe owuwu.
● Teknụzụ nchekwa ike, dị ka teknụzụ mgbake hydrogen, teknụzụ ntụgharị tupu oge eruo, teknụzụ saturation gas na teknụzụ na-ekpo ọkụ ikuku, ka a nakweere iji belata oriri methanol.Site na usoro dị iche iche, a na-ebelata oriri ike kwa ton nke methanol site na 38 ~ 40 GJ ruo 29 ~ 33 GJ.

A na-eji gas eme ihe dị ka akụrụngwa, wee kpoo ya, desulfurized na sachaa ya iji mepụta syngas (nke kachasị H2 na CO).Mgbe mkpakọ ọzọ gasịrị, syngas na-abanye n'ụlọ elu nke methanol iji mepụta methanol n'okpuru ọrụ nke onye na-emepụta ihe.Mgbe njikọ nke crude methanol, site tupu distillation wepụ fusel, rectification nweta okokụre methanol.
