MDEA eke gas desulphurization (desulfurization) skid, nke a na-akpọkwa MDEA sweeting skid na eke gas desulfurization unit, bụ isi ngwaọrụ na-asachapụ eke gas ọcha ma ọ bụ eke gas oyi.
MDEA eke gas desulfurization unit na-nakweere mgbe niile mgbe carbon sọlfọ nke nri gas dịtụ elu, na mgbe nhọrọ nke mwepụ nke H.2S dị mkpa iji nweta gas acid dabara maka nhazi osisi Claus, yana ọnọdụ ndị ọzọ enwere ike ịhọrọ iji wepụ H2 S; Mgbe iwepu H2S ma wepụ nnukwu ego CO2, Enwere ike iji MDEA dị ka usoro amine agwakọta;
Ugbu a, isi desulfurization teknụzụ eji na ulo oru mmepụta n'ụlọ na ná mba ọzọ bụ: akọrọ (anụ ahụ) desulfurization, ndu desulfurization na mmiri desulfurization.
Wet desulfurization gụnyere usoro nnabata na usoro oxidation mmiri. Usoro nnabata kemịkalụ, nke nnabata mmanya amine nọchiri anya ya, ejirila ọtụtụ ebe na ụlọ ọrụ. A na-ebufe hydrogen sulfide na gas gaa na mmiri mmiri iji mee ka gas dị ọcha.
Desulfurization teknụzụ
Nkà na ụzụ desulfurization nke ndụ, n'ọnọdụ micro oxygen, nwere ike ịtụgharị hydrogen sulfide ka ọ bụrụ sọlfọ elemental, mana teknụzụ nke desulfurization nke ndu etobeghị ugbu a.
Akọrọ desulfurization technology na-agụnye ígwè oxide usoro, arụ ọrụ carbon usoro, molekul sieve usoro, ion mgbanwe usoro, membrane nkewa usoro, biochemical usoro, wdg ugbu a, akọrọ PSA technology bụ ihe kasị n'ọtụtụ ebe na-eji na obere-ọnụ ọgụgụ eke gas desulfurization ọgwụgwọ na ụlọ ọrụ. , nke a na-achịkwa nke ọma na kọmputa, arụ ọrụ akpaka, na iwepụ ụlọ elu na-adịghị mma, ka ọ wee nweta ọrụ nchekwa ogologo oge.
desulfurization ụzọ
Amorphous iron hydroxide (usoro akọrọ). Atụmatụ: o nwere njirimara nke oke desulfurization nkenke, ikike sọlfọ dị elu, ike dị mma na enweghị nlekọta. A na-eji ya eme ihe n'ọtụtụ ebe na mwepụ nke hydrogen sulfide na gas, sịntetik gas, biogas, coal gas, coalbed methane na ihe dị iche iche nwere sọlfọ dị iche iche; The amorphous hydroxyl oxidation desulfurization bụ mmeghachi omume desulfurization, nke na-apụghị ịchịkwa desulfurization omimi. Ọ bụ ezigbo desulfurization usoro. Site na saturation nke desulfurizer na ntinye nke ụlọ elu desulfurization, mmetụta desulfurization ga-ebelata nke ukwuu, na ọdịnaya nke hydrogen sulfide na gas dị ọcha ga-ebili nke ọma, ya mere ọ dị mkpa iji dochie desulfurizer n'oge.
