Sulfur Recovery: Ib qho tseem ceeb rau kev ua raws li ib puag ncig

Sulfur yog ib yam khoom uas feem ntau pom nyob rau hauv cov roj av, cov nkev ntuj, thiab lwm yam fossil fuels. Thaum cov roj no raug hlawv, sulfur dioxide (SO2) raug tso tawm rau hauv qhov chaw, uas tuaj yeem ua rau cov kua qaub los nag thiab lwm yam teeb meem rau ib puag ncig. Txhawm rau daws qhov teeb meem no, ntau qhov kev lag luam tau siv cov txheej txheem sulfur rov qab los ntes thiab hloov sulfur dioxide rau hauv cov khoom siv tau zoo.

Sulfur Recovery yog dab tsi?

Sulfur rov qab yog txheej txheem ntawm kev hloov cov sulfur dioxide rau hauv cov tshuaj sulfur lossis sulfuric acid. Cov txheej txheem no feem ntau yog siv nyob rau hauv cov roj refineries, roj ua cov nroj tsuag, thiab lwm yam lag luam uas tsim cov sulfur dioxide ntau npaum li cas los ntawm lawv cov hauj lwm.

Cov kauj ruam yooj yim ntawm cov txheej txheem sulfur rov qab muaj xws li:

Absorption: Thawj kauj ruam hauv kev rov qab los ntawm leej faj yog nqus sulfur dioxide los ntawm cov dej khib nyiab. Qhov no feem ntau yog ua los ntawm cov tshuaj amine los yog lwm yam tshuaj absorbents.

Kev hloov pauv: Thaum cov sulfur dioxide tau nqus, nws hloov mus rau hauv cov tshuaj sulfur lossis sulfuric acid. Qhov no feem ntau yog ua tiav siv lub catalytic converter lossis lwm yam txheej txheem tshuaj.

Kev Sib cais: Cov kauj ruam kawg hauv kev rov qab los ntawm leej faj yog cais cov sulfur lossis sulfuric acid los ntawm cov dej khib nyiab. Qhov no tuaj yeem ua tiav siv ntau txoj hauv kev, suav nrog kev pom, distillation, thiab crystallization.

Vim li cas Sulfur Recovery tseem ceeb?

Sulfur rov qabyog ib qho tseem ceeb rau ntau yam:

Kev ua raws li ib puag ncig: Sulfur dioxide emissions raug tswj los ntawm ib puag ncig cov koom haum hauv ntau lub teb chaws. Sulfur rov qab pab kev lag luam ua raws li cov cai no los ntawm kev ntes thiab hloov cov sulfur dioxide rau hauv cov khoom siv tau zoo.

Kev txuag nqi: Elemental sulfur thiab sulfuric acid yog cov khoom muaj txiaj ntsig uas tuaj yeem muag lossis siv rau lwm cov txheej txheem kev lag luam. Los ntawm kev rov ua cov sulfur, kev lag luam tuaj yeem txo cov khib nyiab thiab tsim cov nyiaj tau los ntxiv.

Kev noj qab haus huv thiab kev nyab xeeb: Sulfur dioxide yog cov pa phem uas tuaj yeem ua rau muaj teeb meem ua pa thiab lwm yam teeb meem kev noj qab haus huv. Los ntawm kev ntes thiab hloov cov sulfur dioxide, kev lag luam tuaj yeem txo qhov kev pheej hmoo ntawm cov neeg ua haujlwm raug thiab txhim kho tag nrho kev nyab xeeb hauv chaw ua haujlwm.

Yuav Ua Li Cas Siv Sulfur Recovery

Kev siv cov tshuaj sulfur rov qab yuav tsum tau ua tib zoo npaj thiab ua tiav. Nov yog qee cov kauj ruam tseem ceeb los xav txog:

Ua ib txoj kev tshawb fawb txog qhov ua tau: Ua ntej siv cov tshuaj sulfur rov qab, nws yog ib qho tseem ceeb uas yuav tau ua txoj kev tshawb fawb txog qhov ua tau los txiav txim seb nws puas muaj txiaj ntsig zoo rau koj txoj kev lag luam. Txoj kev tshawb no yuav tsum xav txog tej yam xws li qhov ntim ntawm sulfur dioxide uas tsim tawm, tus nqi ntawm kev siv cov tshuaj sulfur, thiab cov nyiaj tau los ntawm cov sulfur zoo.

Xaiv cov thev naus laus zis zoo: Muaj ntau ntau cov thev naus laus zis muaj rau kev rov ua kom cov tshuaj sulfur, suav nrog cov txheej txheem Claus, txheej txheem WSA, thiab txheej txheem SUPERCLAUS. Txhua lub tshuab muaj nws qhov zoo thiab qhov tsis zoo, yog li nws yog ib qho tseem ceeb uas yuav tau xaiv ib qho uas haum rau koj cov kev lag luam thiab kev tsim khoom.

Tsim thiab txhim kho cov khoom siv hluav taws xob rov qab: Thaum cov thev naus laus zis tau raug xaiv, cov kauj ruam tom ntej yog tsim thiab nruab cov khoom tsim nyog. Qhov no tej zaum yuav muaj xws li kev nqus yees, catalytic converters, thiab lwm yam khoom siv.

Kev cob qhia cov neeg ua haujlwm: Kev rov qab los ntawm Sulfur yuav tsum muaj kev paub tshwj xeeb thiab kev txawj ntse, yog li nws yog ib qho tseem ceeb rau kev cob qhia cov neeg ua haujlwm txog kev ua haujlwm zoo thiab ua haujlwm zoo. Qhov no yuav suav nrog kev cob qhia txog kev tuav tshuaj, kev tswj cov txheej txheem, thiab cov txheej txheem tu.

Saib xyuas thiab txhim kho cov txheej txheem: Sulfur rov qab yog txheej txheem txuas ntxiv uas yuav tsum tau saib xyuas tas li thiab ua kom zoo dua qub. Qhov no tej zaum yuav suav nrog kev kuaj xyuas cov dej khib nyiab tsis tu ncua, kho cov txheej txheem tsis tu ncua, thiab tswj cov cuab yeej kom ntseeg tau tias kev ua haujlwm zoo.
