Ubuziranenge Bwiza Ubushinwa Glycol Dehydration Inganda Zidasanzwe - Skid yo gutunganya umurizo skid - Rongteng

Ibisobanuro

Isukari ya gazi isanzwe itunganya gazi ikoreshwa cyane mugukemura gaze umurizo wigikoresho cyo kugarura sulfuru, hamwe na gaze yimyanda ya pisine ya sulfure na gaze ya TEG yimyanda yumwuma wibikoresho byo kugarura sulferi.
Igishushanyo nogutunganya ubushobozi bwa skid bihujwe nigikoresho cyo kugarura sulfure nigikoresho cyo kubura amazi.

Gazi isanzwe yumurizo wa gaz skid irashobora kugabanywamo ibyiciro bine.

1. Kugabanya no gukuramo
Ihame ryo kugabanya no kwinjizwa ni uko gazi umurizo iba hydrogène, ibice birimo sulfure muri gaze yumurizo bigabanuka kugeza kuri H2S, H2S yabyaye ihitanwa nuburyo bwa amine, hanyuma amaherezo kuvuka cyangwa gaze bikavamo kugirango binjire mubice bya Claus kugirango bizenguruke. Hydrogenation inzira ifite ishoramari ryinshi nigiciro kinini cyo gukora, ariko ikoreshwa cyane mubihugu no mukarere bifite ibisabwa cyane byo kurengera ibidukikije kuko ishobora kugera ku musaruro mwinshi wa sulferi, nko hejuru ya 99.8%.

2. Uburyo bwo gukuramo Oxidation
Uburyo bwa Oxidation uburyo bwo kubamo ni uburyo bwambere okiside sulfide muri gaze yumurizo kugeza kuri SO2, hanyuma ikakira SO2 ikoresheje igisubizo (cyangwa solvent), hanyuma ikagarura muburyo bwa sulfate, sulfide na SO2.
Hariho uburyo bwinshi bwubwoko nkubu, inyinshi murizo zikoreshwa mugukoresha gazi ya flue cyangwa gutunganya gaz umurizo uva mumashanyarazi hamwe ninganda za acide sulfurike, kandi uburyo bwa Wellman Lord bukoreshwa mugutunganya gazi umurizo wa Claus.

3. Ubushyuhe buke Inzira ya Claus
Ubushyuhe buke Ikoranabuhanga rya Claus rirangwa na reaction ya Claus munsi yikime cya sulfure, bityo nanone yitwa sub dew point sulfure yo kugarura ibintu. Claus reaction nigikorwa gikomeye cya exothermic reaction. Kubwibyo, ubushyuhe buke bufasha guhindura ihindagurika ryerekezo yerekeza kumasoko ya sulferi, bishobora guteza imbere kugarura sulfure. Ukurikije isano iri hagati yimyitwarire ya Claus hamwe nubushyuhe, ubushyuhe buke Claus irashobora kugabanywa mubushyuhe buke bwigenga Claus hamwe nubushyuhe buke bwa Claus.

4. Amazi yicyiciro cya okiside itaziguye
Amazi ya fiside itaziguye ni uburyo bwa tekinoroji itangiza H2S kuri sulfure yibanze. Ihame ryiki gikorwa ni ugukuramo H2S muri gaze yumurizo hamwe nigisubizo cya desulfurizasi, hanyuma ukayitera okiside kugirango itange sulfure yibanze.

Ibipimo bya tekiniki

1, SO2 ≤ 400mg / Nm3 (ishingiro ryumye, 3vol% O2)
2, Igihe cyo gukora buri mwaka amasaha 8000
3, Gukoresha ibintu byoroshye 50% ~ 120%
