Waa maxay sababta loo hawlgeliyay alumina muhiim u ah Geedi-socodka Soo-kabashada Sulfur Claus?
Qalabka aluminium ee ka shaqeeya Qaybaha Soo-kabashada Claus Sulfur waxay u taagan yihiin fasalka ugu qadiimiga ah uguna isticmaalka badan ee kicinta codsigan. Nadiifinta sare - alumina firfircoon ee firfircoon waxay kicisaa falcelinta ka dhaxaysa hydrogen sulfide (H2S) iyo sulfur dioxide (SO2Si loo soo saaro baaruud elemental (S), iyadoo isla mar ahaantaana kor u qaadaysa hydrolysis sulfur{0}} ay ku jiraan{1} alaabooyinka sida carbonyl sulfide (COS) iyo carbon disulfide (CS)2), si kor loogu qaado heerka soo kabashada baaruudda.
Waa maxay habka Claus soo kabashada baaruudda?
Habka Claus waa mid ka mid ah tignoolajiyada soo kabashada baaruudda ee aadka loo isticmaalo warshadaha casriga ah. Waxaa inta badan loo shaqeeyaa si loogu beddelo gaaska acidic ka kooban H2S galay elemental S, iyadoo la yareynayo wasakhowga deegaanka ee ay keento qiiqa tooska ah ee sulfides. Habka soo kabashada baaruudda Claus waxa ay quseysaa goobo warshadeed oo kala duwan kuwaaso dhaliya tiro badan oo baaruud ah{1}}
* Sifeynta saliidda: si looga soo kabsado baaruudka gaasaska acid ee la soo saaro inta lagu jiro hababka sifaynta;
* Ka-hortagga gaaska dabiiciga ah: si loo daweeyo gaaska acidic ee soo baxa inta lagu jiro desulfurization gaaska dabiiciga ah;
* Warshadaha kiimikaad dhuxusha: in lagu daweeyo baaruud{0}} gaasas aashito ah oo la soo saaro inta lagu jiro gaaska dhuxusha iyo sifaynta syngas;
* Warshadaha Coking: si loogu beddelo hydrogen sulfide ee gaaska foornada kookaha oo loo beddelo baaruud elemental;
* Warshadaha kiimikaad: si looga soo kabsado baaruudda H2S - oo ka kooban gaasaska habka;
* Sulfide -warshadaha laxidhiidha: si loola tacaalo baaruudda{1}}ka kooban gaasaska qashinka ee sulfuric acid, viscose, iyo fiilooyinka kiimikada.
Halkee buu Alumina Kataliyetka Dhigan yahay Habka Claus?
Habka caadiga ah ee habka Claus soo kabashada baaruudku wuxuu ka kooban yahay nidaamka quudinta gaaska aashitada, foornada gaaska aashitada, kuleyliyaha kulaylka wasakhda, qaboojiyaha baaruudka, reactors Claus catalytic, iyo godka ururinta baaruudka dareeraha ah ama haanta daboolka baaruudka.
Dareen-celinta ugu muhiimsan ee habka Claus waa falcelinta u dhaxaysa H2S iyo SO2si loo soo saaro baaruud curiye ah. Ficil ahaan, qayb ka mid ah H2S marka hore waa la gubay si loo dhaliyo SO2; natiijada SO2ka dibna ka falceliya inta soo hartay H2Si ka sarreeya kicinta{0}Claus reaction- si loo soo saaro uumiga baaruudda, kaas oo soo saara baaruud dareere ah marka la qaboojiyo.
Sidaa darteed,Claus alumina kicintaWaxa ugu horrayn loo isticmaalaa reactor-yaashan katalytiga ah. Iyo sariiraha sariiraha kicinta ee Claus-ka caadiga ah waxay si caadi ah u shaqeeyaan aluminium firfircoon.
Hawlaha Alumina Aluminium Firfircoon ee Habraaca Claus
Katalinta falcelinta Claus ee ugu weyn. Tani waa shaqada ugu muhiimsan! Kataliye la'aan, heerka falcelinta ee u dhexeeya H2S iyo SO2waa mid gaabis ah; si kastaba ha ahaatee, alumina firfircooni waxay bixisaa goobo badan oo firfircoon, taas oo awood u siinaysa falcelinta si degdeg ah u wajahdo dheellitirka heerkulka warshadaha ahaan la aqbali karo.
Xakamaynta COS hydrolysis. Marka laga soo tago H2S, gaaska aashitada ayaa caadi ahaan ka kooban CO2, hydrocarbons, iyo xaddi yar oo sulfide organic. Foornada falcelinta kulaylka, baaruudda qaarkood{1}} oo ka kooban iskudhisyo organic waxay sameeyaan COS iyo CS2. Alumina firfircooni waxay kicisaa beddelka baaruudda gudaha COS oo dib ugu noqota H2S, oo u oggolaanaysa inay gasho nidaamka falcelinta Claus; Tani waxay muhiim u tahay in la kordhiyo wadarta heerka soo kabashada baaruudda.
Xakamaynta CS2hydrolysis. CS2waa maxsuul ka dhashay walaac gaar ah oo ku saabsan habka Claus. Hydrolysis ee CS2waxay u beddeshaa baaruudka ku jira molecule-ka oo dib ugu noqda H2S, oo awood u siinaysa inay ka qayb qaadato falcelinta Claus; Tani waa shaqo kale oo muhiim ah oo ka mid ah kicinta alumina ee firfircoon.
Waa maxay sababta Alumina-da loo hawlgeliyay ay lagama maarmaan u tahay soo kabashada Claus Sulfur?
Wixii alumina{0}kusalaysan ee Claus, furuhu si fudud maaha in la kordhiyo Al2O3nuxurka. Taa beddelkeeda, waxay u baahan tahay hagaajin dhammaystiran oo meel gaar ah oo dusha sare ah, qaab dhismeedka daloolka, dhaqdhaqaaqa dusha sare, iyo iska caabinta debcinta.
Marka la eego cabbirrada molecular ee kala duwan ee H2S, SO2, COS, CS2iyo H2O{{0}iyo xaqiiqda ah in falcelinta Claus ay ku lug leedahay fidinta gaasaska kakooban ee badan oo ku dhex jira qaybaha kicinta{2}} maaraynta cabirka daloolka waa muhiim. Haddii daloolada ay aad u yar yihiin, fidinta falcelinta ayaa xannibaysa waxaana kor u kaca caabbinta faafinta gudaha, taas oo ka hortagaysa ka faa'iidaysiga buuxa ee goobaha firfircoon ee kicinta. Taa beddelkeeda, haddii daloollada ay aad u weyn yihiin, tirada goobaha firfircooni way yaraanayaan. Sidaa awgeed, kiciyayaasha Claus warshaduhu waxay u baahan yihiin qaybinta cabbirka daloolka si gaar ah loo farsameeyay, alumina firfircooni waxay ku siin kartaa sifooyinka dusha sare ee lagama maarmaanka ah iyo qaab dhismeedka daldaloolada si loo buuxiyo shuruudahan.
Kiimikada Sinmatwaxay bixisaa nadiif ah oo saraysa-kicinta aluminium firfircoongaar ahaan habka Claus soo kabashada baaruudda. Faahfaahin dheeraad ah, fadlan tixraacaluminium firfircoonqaybta alaabta.
