Igikoresho cyo kuvura imyuka yo mu murizo

Ibisobanuro

Igikoresho cyo kuvura imyuka ikomoka ku gasi karemano gikoreshwa cyane cyane mu kuvura imyuka ikomoka ku gasi karemano, kimwe n'imyuka ikomoka ku kidendezi cy'amazi cya sulfure n'igikoresho cyo kuvura imyuka ikomoka ku gasi karemano cya TEG.
Igishushanyo n'ubushobozi bwo gutunganya ikiyunguruzo bihuzwa n'igikoresho cyo kugarura isukari hamwe n'igikoresho cyo gukura amazi mu mubiri.

Uburyo bwo kuvura imyuka ikomoka ku gasi karemano bushobora kugabanywamo ibyiciro bine.

1. Uburyo bwo kugabanya no kwinjiza
Ihame ryo kugabanya no kwinjiza umwuka ni uko umwuka wo mu murizo uterwa na hydrogen, ibice birimo sulfure mu mwuka wo mu murizo bikagabanuka bikagera kuri H2S, H2S ikorwa ikanyuzwa mu buryo bw’umwihariko hakoreshejwe uburyo bwa amine, hanyuma umwuka wongera kuzura cyangwa ukavanwamo kugira ngo winjire mu gice cya Claus kugira ngo habeho uburyo bwo kuzenguruka. Uburyo bwo gukwirakwiza hydrogen bufite ishoramari rihanitse kandi bufite ikiguzi kinini cyo gukora, ariko ikoreshwa cyane mu bihugu n'uturere dufite ibisabwa byinshi byo kurengera ibidukikije kuko ishobora kugera ku musaruro mwinshi wa sulfure, nko ku kigero kirenga 99.8%.

2. Uburyo bwo kwinjiza okiside
Uburyo bwo kwinjiza okiside ni uburyo bubanza kongerera sulfide mu mwuka wo mu gifu kuri SO2, hanyuma bugakurura SO2 hamwe n'umuti (cyangwa solvent), hanyuma bukayigarura mu buryo bwa sulfate, sulfide na SO2.
Hari uburyo bwinshi bukoreshwa muri ubwo bwoko, bwinshi muri bwo bukoreshwa mu gukuraho imyuka ihumanya cyangwa kuvura imyuka yo mu mugongo iva mu byuma bishongesha ibyuma n'ibimera bishyushya aside sulfurike, naho uburyo bwa Wellman Lord bukoreshwa mu kuvura imyuka yo mu mugongo ya Claus.

3. Uburyo bwa Claus bushyuha cyane
Ikoranabuhanga rya Claus rikoresha ubushyuhe buke rirangwa n'imikorere ya Claus munsi y'urugero rw'umurabyo wa sulfur, bityo nanone ryitwa inzira yo kugarura sulfur mu gice cy'umurabyo. Uburyo bwa Claus bukoresha uburyo bukomeye bwo gusubiza sulfur mu kirere. Kubwibyo, ubushyuhe buke butuma habaho impinduka mu buryo bw'uburinganire mu cyerekezo cyo kubyara sulfur, ibi bikaba bishobora kunoza imikorere ya sulfur. Dukurikije isano iri hagati ya Claus na unit, uburyo bwa Claus bukoresha ubushyuhe buke bushobora kugabanywamo uburyo bwa Claus bukoresha ubushyuhe buke bushobora kugabanywamo uburyo bwigenga bwa Claus bukoresha ubushyuhe buke n'uburyo bwa Claus bukoresha ubushyuhe buke buhuriweho.

4. Uburyo bwo kugabanya ubushyuhe mu gice cy'amazi
Uburyo bwo kugabanya ubushyuhe mu buryo butaziguye mu gice cy'amazi ni ubwoko bw'ikoranabuhanga rikoresha H2S mu buryo butaziguye muri sulfur. Ihame ry'iyi nzira ni ukwinjiza H2S mu mwuka w'inyuma ukoresheje umuti wo kugabanya ubushyuhe, hanyuma ukayigabanya kugira ngo ikore sulfur.

Ibipimo bya tekiniki

1. SO2 ≤ 400mg / Nm3 (ishingiro ryumye, 3vol% O2)
2, Igihe cyo gukora buri mwaka ni amasaha 8000
3, Uburyo bworoshye bwo gukora 50% ~ 120%
