Njira Zabwino Kwambiri Zoyeretsera Sodium Hydrosulfide Moyenerera

Background

Mu mafakitale opanga mafuta, mafakitale oyeretsera nthawi zambiri amapanga mpweya wa asidi panthawi yokonza zinthu monga kusungunuka kwa vacuum ndi kusweka kwa catalytic. Mpweya wa asidiwu nthawi zambiri umakhala ndi 85%-95% ya hydrogen sulfide, 3%-10% ya carbon dioxide, 2%-5% ya mpweya wachilengedwe, ndi zigawo zina za 0.5%-3%. Makampani oyeretsera ang'onoang'ono komanso apakatikati nthawi zambiri amagwiritsa ntchito yankho la 30% la caustic soda kuti ayamwe mpweya wa acidic womwe umapangidwa poyeretsera. Caustic soda imachitapo kanthu ndi hydrogen sulfide kuti ipange Sodium Hydrosulfide . Pamene kuchuluka kwa sodium hydrosulfide mu yankho kufika pa 30%, yankholo limachulukirachulukira. Pambuyo pa kutaya madzi m'thupi ndi kuchuluka, kuchuluka kwa sodium hydrosulfide mu yankho kumatha kufika pa 70%, ndipo sodium hydrosulfide imakonzedwa m'zidutswa.

Komabe, kukhalapo kwa mpweya woipa mu mpweya acidic amapanga sodium carbonate zonyansa pa ndondomeko ya mankhwala, zomwe zimakhudza chiyero cha sodium hydrosulfide mankhwala. Kuphatikiza apo, kugwiritsa ntchito chopukusira chotseguka kuti mudulire sodium hydrosulfide yosungunuka kumatha kupangitsa kuti makutidwe ndi okosijeni azitha kutulutsa mpweya mumlengalenga, kupanga thiosulfate, yomwe imakonda kuwonongeka komanso yovuta kusunga. Kudula kotseguka kumathandizanso kutulutsa mpweya wokwiyitsa, kuwononga chilengedwe.

Njira Yogwira Ntchito

1. Kupatukana kwa Centrifugal:

Kusamutsa sodium hydrosulfide anaikira njira kuchokera thanki ndende kupita yopingasa wononga centrifuge kwa kulekana, kupeza crystallized mchere ndi wosungunuka monohydrate sodium hydrosulfide.

2. Vacuum Insulation ndi Kuzizira:

Tumizani chitsulo chosungunuka cha monohydrate sodium hydrosulfide, pambuyo pa kupatukana kwa mchere wonyezimira, ku thanki ya vacuum kutchinjiriza kwa kutentha. Kenako, ipopeni mu chopondera cha vacuum paddle kuti izizirike ndi kulimba kukhala mapepala owonda.

3. Kunyamula Basi:

Mapepala a sodium hydrosulfide amatulutsidwa kudzera mu valavu ya nyenyezi mu makina odzaza matumba kuti apangidwe.

Kuphatikiza apo, njira yoyeretsera sodium hydrosulfide imaphatikizapo izi:

1. Kusamutsa sodium hydrosulfide anaikira njira yothetsera ndende ku thanki yopingasa wononga centrifuge kuti alekanitse, kupeza crystallized mchere ndi kusungunuka monohydrate sodium hydrosulfide.

2. Tumizani mchere wonyezimira womwe umapezeka kuchokera ku centrifugation kupita ku chowumitsira, pomwe umayamba kutaya madzi m'thupi mu gawo lotenthetsera chapamwamba cha chowumitsira, kenako ndikulowa m'gawo loziziritsa la m'munsi kuti muziziritsa musanasonkhanitsidwe ngati wothandizira madzi kuti mugwiritse ntchito mtsogolo.

3. Kusungunuka kwa monohydrate sodium hydrosulfide, pambuyo pa kupatukana kwa mchere wonyezimira, kumatumizidwa ku thanki yotsekemera yotsekemera kuti itenthe. Kenako amaponyedwa mu vacuum paddle cooler kuti aziziziritsa ndi kulimba kukhala mapepala owonda.

4. Mapepala a sodium hydrosulfide amatulutsidwa kudzera mu valavu ya nyenyezi mu makina odzaza matumba kuti apake.

5. Gawo la mpweya wotengedwa mu thanki yotsekera vacuum ndi choziziritsa cha vacuum paddle amathandizidwa kudzera munjira yopangira gasi wa zinyalala.

Kutsiliza

Njira imeneyi choyamba amalekanitsa osakaniza crystallized mchere, monga sodium carbonate, ndi sodium hydrosulfide anaikira njira. Kenako, chitsulo chosungunuka cha monohydrate sodium hydrosulfide chimapangidwa mwachindunji kukhala mapepala owonda pogwiritsa ntchito vacuum paddle ozizira. Pomaliza, mankhwalawa amapakidwa pogwiritsa ntchito makina onyamula okha. Kuchuluka kwa zonyansa za sodium carbonate muzogulitsa kumachepetsedwa kuchoka pa 2.4% mpaka 0.3%. Njira yoziziritsa imachitika m'malo ovuta, omwe amachepetsa mwayi wa sodium hydrosulfide kukumana ndi mpweya ndikulowa makutidwe ndi okosijeni, zomwe zimalepheretsa kuwonongeka kwazinthu. Kugwiritsiridwa ntchito kwa dongosolo lotsekedwa mokwanira kuyeretsa sodium hydrosulfide kumatsimikizira kuti palibe mpweya woipa womwe umatulutsidwa panthawiyi, kupeŵa kuipitsidwa kwachiwiri kwa chilengedwe. Mapepala a sodium hydrosulfide amanyamula mwachindunji, kuteteza kuipitsidwa panthawi yosungidwa. Kuphatikiza apo, chopangidwachi chimakhala ndi njira yosavuta, chimafuna zida zochepa, ndipo chimakhala ndi zotsika mtengo.
