3.2.2.2 Kev tshem tawm Mercury thiab ziab chav tsev ntawm cov pa roj

1) Cov txheej txheem piav qhia

Lub ntuj gas los ntawm cov khoom noj roj deacidification unit nkag mus rau sulfur impregnated activated carbon adsorber. Mercury reacts nrog cov leej faj ntawm cov sulfur impregnated activated carbon los tsim mercury sulfide, uas yog adsorbed rau ntawm activated carbon, thiaj li mus cuag lub hom phiaj ntawm mercury tshem tawm. Cov ntsiab lus mercury ntawm natural gas los ntawm mercury tshem tawm yog tsawg dua 0.01μg / Nm³.

Ib lub mercury tshem tawm yuav tsum tau teem, thiab cov sulfur impregnated activated carbon yuav tsum tau hloov raws li qhov kev xeem.

Cov pa roj carbon monoxide tom qab tshem tawm cov mercury nkag mus rau hauv chav ua kom qhuav. Chav tsev txais yuav kub viav vias adsorption tshuab rau roj sib cais thiab purification. Kub viav vias adsorption tshuab yog ua raws li lub cev adsorption ntawm cov roj molecules nyob rau sab hauv ntawm adsorbent (cov khoom ntxeem tau), thiab siv cov yam ntxwv uas cov adsorption muaj peev xwm ntawm adsorbent rau cov pa hloov nrog qhov sib txawv adsorption kub thiab siab, nyob rau hauv cov xwm txheej uas cov adsorption xaiv adsorbs sib txawv roj Cheebtsam, ib co Cheebtsam nyob rau hauv lub lowbed sib tov thiab adsorption siab. los ntawm cov txheej txheem adsorber. Cov khoom adsorbed no yog desorbed ntawm qhov kub thiab txias thiab tsis tshua muaj siab rau tom ntej no kub thiab high-pressure adsorption. Ntau qhov adsorption yees tuaj yeem siv los ua kom tiav lub hom phiaj ntawm kev sib cais roj txuas ntxiv.

Cov pa roj kom qhuav thiab hnyav hydrocarbon tshem tawm chav tsev yog nruab nrog peb lub adsorbers rau kev hloov pauv, ib qho rau adsorption, ib qho rau tshuab txias thiab ib qho rau cua sov rov tsim dua tshiab.

Cov roj pub los ntawm lub demercuration ntauwd nkag mus rau sab saum toj ntawm adsorber, tshem tawm cov dej los ntawm molecular sieve adsorption, tawm hauv qab ntawm adsorber, thiab nkag mus rau hauv cov khoom noj roj hnyav hydrocarbon tshem tawm tom qab lub cev qhuav dej.

Lub tshuab pub roj kom qhuav siv me me ntawm cov pa roj ua kom txias tshuab thiab rov tsim dua tshiab. Tom qab cov roj regeneration tawm ntawm lub adsorption ntauwd, nws rov qab mus rau qhov nkag ntawm lub tshuab ziab khaub ncaws hauv lub xeev adsorption tom qab txias thiab sib cais.

Cov roj regeneration ua ntej dhau los ntawm cov cua txias adsorber los ntawm sab saum toj mus rau hauv qab, thiab tom qab ntawd cov roj regeneration yog rhuab mus rau qhov kub thiab txias ntawm 180 ~ 260 ℃ los ntawm lub regeneration rhaub, thiab ces nkag mus rau hauv qab ntawm adsorber rau hydrolyze thiab adsorb adsorbed adsorbent. Cov roj regeneration tuaj tawm ntawm lub tshuab ziab khaub ncaws sab saum toj thiab nkag mus rau cov roj regeneration gas separator tom qab txias los ntawm lub tshuab regeneration cooler. Tom qab sib cais cov kua, nws rov qab mus rau pem hauv ntej kawg ntawm lub adsorber.

Tom qab dhau los ntawm chav tsev, cov dej hauv cov nkev qhuav yog ≤ 1ppm.

Cov khoom tseem ceeb yog adsorption ntauwd, regeneration heater, regeneration gas cooler thiab regeneration gas separator.

1) Cov txheej txheem piav qhia

Lub lim dej yog nruab nrog lub lim, uas tuaj yeem hloov pauv raws li cov ntaub ntawv tiv thaiv kom ua tiav lub hom phiaj ntawm kev lim dej molecular sieve thiab activated carbon plua plav.

Tom qab tshem tawm cov plua plav, cov plua plav hauv cov pa roj yog tsawg dua 10μm.

Cov cuab yeej tseem ceeb yog plua plav lim.
