I-Feedstock: igesi yokwenziwa, igesi yentsimi yeoyile, igesi yendalo, igesi yamalahle. Inganyanga umsinga wegesi nge-inorganic sulfur ephezulu

njenge-23g/m3 enezinga elifanelekileyo lokuhlanjululwa. Ingacoca nomsinga wegesi ukuya kuthi ga kwi-20mg/m3 elula ngolo hlobo.

i-organic sulfur njenge-COS ukuya ngaphantsi kwe-0.1ppm.

5. Iyalayisha

Ubunzulu bokulayisha: Kucetyiswa i-L/D ephezulu (min3). Uqwalaselo lwee-reactors ezimbini kuluhlu lunokuphucula ukusetyenziswa

ukusebenza kakuhle kwe-adsorbent.

Inkqubo yokulayisha:

(1) Coca i-reactor phambi kokuba ulayishe;

(2) Beka iigridi ezimbini ezingenasici ezinobukhulu obuncinci be-mesh kune-adsorbent;

(3) Layisha umaleko we-100mm wee-Φ10—20mm ezirhabaxa kwiigridi ezingenasici;

(4) Vala i-adsorbent ukuze ususe uthuli;

(5) Sebenzisa isixhobo esikhethekileyo ukuqinisekisa ukusasazwa ngokulinganayo kwe-adsorbent ebhedini;

(6) Hlola ukufana kwebhedi ngexesha lokulayisha. Xa kufuneka kusetyenziswe i-inside-reactor, kufuneka kubekwe ipleyiti yomthi kwi-adsorbent ukuze umqhubi ame kuyo.

(7)Faka igridi engatyiwayo enobukhulu obuncinci be-mesh kune-adsorbent kunye nomaleko we-100mm we-Φ20—30mm refractory spheres phezulu kwebhedi ye-adsorbent ukuze kuthintelwe ukungena kwe-adsorbent kwaye kuqinisekiswe ukuba

ukusasazwa ngokulinganayo komjelo wegesi.

6. Ukuqalisa ishishini

(1)Tshintsha inkqubo nge-nitrogen okanye ezinye iigesi ezingasebenziyo de uxinzelelo lwe-oksijini kwigesi lube ngaphantsi kwe-0.5%;

(2) Fudumeza umjelo wokutya nge-nitrogen okanye igesi yokutya phantsi koxinzelelo oluphezulu okanye oluphezulu;

(3) Isantya sokufudumeza: 50°C/h ukusuka kubushushu begumbi ukuya kwi-150°C (ene-nitrogen); 150°C kangangeeyure ezi-2 (xa i-heating medium isetyenziswa

itshintshelwe kwigesi yokutya), 30°C/h ngaphezulu kwe-150°C ide ifikelele kubushushu obufunekayo.

(4) Lungisa uxinzelelo ngokuthe chu de kube lufikelele kuxinzelelo lomsebenzi.

(5) Emva kokufudumeza kwangaphambili kunye nokunyuka koxinzelelo, inkqubo kufuneka iqale isebenze ngesiqingatha somthwalo kangangeeyure ezi-8. Emva koko inyuse

umthwalo ngokuthe chu xa umsebenzi uzinzile de kube ngumsebenzi opheleleyo.

7.Cima

(1) Ukunikezelwa kwegesi (ioyile) evaliweyo ngokukhawuleza.

Vala iivalvu zokungena kunye nezokuphuma. Gcina ubushushu kunye noxinzelelo. Ukuba kuyimfuneko, sebenzisa i-nitrogen okanye i-hydrogen-nitrogen

igesi ukugcina uxinzelelo ukuthintela uxinzelelo olubi.

(2) Ukutshintshwa kwe-desulfurization absorbent

Vala iivalvu zokungena kunye nezokuphuma. Yehlisa kancinci ubushushu kunye noxinzelelo ukuze zifikelele kwimeko yemozulu. Emva koko yahlula

i-reactor ye-desulfurization kwinkqubo yemveliso. Buyisela i-reactor ngomoya endaweni yayo de kufikelelwe kuxinzelelo lwe-oksijini olungaphezulu kwama-20%. Vula i-reactor uze ukhuphe i-adsorbent.

(3) Ukugcinwa kwezixhobo (ukulungiswa)

Landela inkqubo efanayo naleyo iboniswe apha ngasentla ngaphandle kokuba uxinzelelo kufuneka lwehliswe kwi-0.5MPa/10min kunye nobushushu.

yehliswe ngokwendalo.

I-adsorbent engafakwanga kufuneka igcinwe kwiileya ezahlukeneyo. Hlalutya iisampulu ezithathwe kwileya nganye ukuze ubone

imeko kunye nobomi benkonzo ye-adsorbent.

8. Uthutho kunye nokugcinwa

(1) Imveliso ye-adsorbent ipakishwe kwiibharele zeplastiki okanye zesinyithi ezineplastiki ukuthintela ukufuma kunye neekhemikhali

ungcoliseko.

(2) Ukuwa, ukungqubana kunye nokungcangcazela okunamandla kufuneka kuthintelwe ngexesha lokuthuthwa ukuze kuthintelwe ukucolwa kwenkunkuma

isithambisi.

(3) Imveliso efunxayo kufuneka ithintelwe ekudibaneni neekhemikhali ngexesha lokuthuthwa nokugcinwa kwayo.

(4) Imveliso ingagcinwa iminyaka emi-3 ukuya kwemi-5 ngaphandle kokuwohloka kweempawu zayo ukuba ivalwe ngokufanelekileyo.
