Njira Zabwino Kwambiri Zoyeretsera Sodium Hydrosulfide Moyenerera

Background

Mu makampani opanga mafuta, mafakitale oyeretsera mafuta nthawi zambiri amapanga mpweya wa asidi panthawi yokonza zinthu monga kusungunuka kwa vacuum ndi kusweka kwa catalytic. Mpweya wa asidi uwu nthawi zambiri umakhala ndi 85%-95% ya hydrogen sulfide, 3%-10%. Carbon mpweya woipa, 2%-5% ya mpweya wachilengedwe, ndi 0.5%-3% ya zinthu zina. Makampani oyeretsera ang'onoang'ono ndi apakatikati nthawi zambiri amagwiritsa ntchito yankho la 30% la soda kuti ayamwe mpweya wa asidi womwe umapangidwa panthawi yoyeretsera. Soda woipa amachitapo kanthu ndi hydrogen sulfide kuti apange. Sodium Hydrosulfide. Pamene sodium hydrosulfide ndende mu njira kufika 30%, yankho ndi moikirapo. Pambuyo madzi m'thupi ndi ndende, ndi sodium hydrosulfide zili mu yankho akhoza kufika 70%, ndi sodium hydrosulfide ndiye kukonzedwa mu magawo.

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.
