MDEA desulfurization (desulfurization) skid, nke a na-akpọkwa MDEA sweeting skid, bụ ngwaọrụ dị mkpa na-eme ka ikuku dị ọcha ma ọ bụ ntụ oyi ikuku.

MDEA desulfurization skid maka eke gas na-nakweere mgbe carbon sọlfọ nke ndepụta gas dịtụ elu , na mgbe nhọrọ mwepụ nke H2S dị mkpa iji nweta acid gas kwesịrị ekwesị maka Claus osisi nhazi, na ọnọdụ ndị ọzọ nwere ike họrọ wepụ H2S; Mgbe ị na-ewepụ H2S ma wepụ nnukwu CO2, MDEA na alcoholamine ndị ọzọ (dị ka DEA) nwere ike iji dị ka usoro amine agwakọta;

Usoro

Mgbe a na-ewepụ ihe ndị siri ike na mmiri mmiri na-adịghị ọcha site na gas nri site na onye na-ekewapụta na ihe nzacha, a na-ehichapụ gas nri na ụlọ elu valve na-ese n'elu. A na-eji ngwọta Methyl diethanol (MDEA) mee ihe dị ka desulphurizer na ụlọ elu.

Mgbe ewepụsịrị ntakịrị ụfụfụ mmiri MDEA site na gas site na nkesa nkesa mmiri mmiri, ikuku ikuku mmiri na-abanye n'ụlọ elu akpịrị ịkpọ nkụ.

A na-eji TEG eme ka mmiri dị n'ime mmiri dị n'ime ụlọ elu ahụ, a na-ejikwa gas kpọrọ nkụ sitere na ụlọ elu nkụnwụ ahụ. A na-eji gas sitere n'okike mee ihe dị ka gas akụrụngwa ruru eru maka mbupụ.

Mmiri mmiri MDEA bara ụba na ụlọ elu desulfurization bụ ọkụ na-ekpochapụ iji wepụ hydrocarbons wee mee nzacha. Mgbe ahụ, ọ na-ekpo ọkụ site na uzuoku iji nwetaghachi mmiri mmiri MDEA na-adịghị mma, nke a na-agbanye n'ụlọ elu desulfurization maka cyclic desulfurization.

A na-ewepụ gas sitere na mmiri ọkụ mmiri MDEA site na onye nkesa mmiri acid, na ihe ngwọta MDEA kewapụrụ na-agbaba na ụlọ elu desulfurization. A na-ekpo ọkụ TEG bara ụba nke a na-eji na ụlọ elu akpịrị ịkpọ nkụ iji mee ka ngwọta TEG adịghị mma site na kọlụm distillation, tank tank na nyo.

Mgbe ịgbanye H2S gas n'ime tank gas nchekwa acid na nkewa nke acid mmiri separator, ọ na-preheated na mmeghachi omume ọkụ na-emeghachi omume na ikuku supped ikuku compressor na-etolite SO2, nke na-emeghachi omume na ndị fọdụrụ H2S na-etolite elemental sọlfọ, wee na-enweta sọlfọ mgbe jụrụ.
