Nzira Dzakanakisisa dzeKuchenesa Sodium Hydrosulfide Zvinobudirira

kumashure

In the petrochemical industry, refineries typically produce acidic gases during processing operations such as vacuum distillation and catalytic cracking. These acidic gases generally consist of 85%-95% hydrogen sulfide, 3%-10% kabhoni dioxide, 2%-5% organic gases, and 0.5%-3% other components. Small and medium-sized refineries usually use a 30% caustic soda solution to absorb the acidic gases generated during refining. Caustic soda reacts with hydrogen sulfide to form Sodium Hydrosulfide. Apo iyo sodium hydrosulfide concentration mumhinduro inosvika 30%, mhinduro yacho inowedzera kuiswa. Mushure mekupera mvura uye kuisa pfungwa, iyo sodium hydrosulfide yemukati mune mhinduro inogona kusvika 70%, uye iyo sodium hydrosulfide inozogadziriswa kuita zvidimbu.

Nekudaro, kuvepo kwekabhoni dhiabhorosi mumagasi ane acidic kunogadzira sodium carbonate tsvina panguva yekurapa, iyo inokanganisa kuchena kweiyo sodium hydrosulfide chigadzirwa. Pamusoro pezvo, kushandisa yakavhurika rolling slicer kucheka iyo yakanyungudutswa sodium hydrosulfide inogona kutungamira kune oxidation maitiro neokisijeni mumhepo, ichigadzira thiosulfate, iyo inotadza kuparara uye yakaoma kuchengeta. Open slicing zvakare inokonzeresa kuburitsa magasi anoshatirisa, achisvibisa nharaunda yekugadzira.

Inoshanda Nzira

1. Centrifugal Separation:

Chinja sodium hydrosulfide concentrated solution kubva kuconcentrate tank kuenda kune yakachinjika sikururu centrifuge yekuparadzana, uchiwana munyu wakanatswa uye yakanyungudutswa monohydrate sodium hydrosulfide.

2. Vacuum Insulation uye Kutonhodza:

Tumira iyo yakanyungudutswa yemonohydrate sodium hydrosulfide, mushure mekuparadzaniswa kwemunyu, kune vacuum insulation tank yekudziya. Wobva waipombera muvacuum paddle inotonhorera yekutonhodza uye kugadzika mumapepa matete.

3. Automatic Bagging:

Mashizha e sodium hydrosulfide anoburitswa kuburikidza nevharuvhu yenyeredzi mumushini weotomatiki webhegi wekurongedza.

Kupfuurirazve, nzira yekuchenesa yesodium hydrosulfide inosanganisira anotevera matanho:

1. Shandura sodium hydrosulfide concentrated solution kubva muconcentrate tank kuenda kune horizontal screw centrifuge kuti iparadzanise, kuwana crystallized munyu uye yakanyungudutswa monohydrate sodium hydrosulfide.

2. Tumira munyu wakasvibiswa unowanikwa kubva ku centrifugation kusvika kune wakaoma, uko unotanga kupera mvura muchikamu chekupisa chepamusoro chemuomesi, uye wozopinda muchikamu chekutonhora chechikamu chepasi kuti chitonhodze chisati chaunganidzwa semugadziri wekuchenesa mvura kuitira kushandiswa gare gare.

3. Iyo yakanyungudutswa yemonohydrate sodium hydrosulfide, mushure mekuparadzaniswa kwemunyu kwakanyatsojeka, inotumirwa kune vacuum insulation tank yekupisa. Inobva yapombwa muvacuum paddle inotonhorera kuti itonhodze uye igadzikane kuita mapepa matete.

4. Mashizha e-sodium hydrosulfide anobudiswa kuburikidza nevharuvhu yenyeredzi mumuchina weautomatic bagging wekurongedza.

5. Chikamu chegasi chakabviswa kubva muvhavha yekuvharidzira tangi uye vacuum paddle cooler inobatwa kuburikidza nemararamiro ekugadzirisa gasi.

mhedziso

Iyi nzira inotanga kupatsanura yakasanganiswa crystallized munyu, senge sodium carbonate, kubva kune sodium hydrosulfide concentrated solution. Zvadaro, iyo yakanyungudutswa yemonohydrate sodium hydrosulfide inosimbiswa zvakananga kuita mapepa matete uchishandisa vacuum paddle inotonhorera. Pakupedzisira, chigadzirwa chacho chinoputirwa uchishandisa otomatiki bagging muchina. Iko kusanganiswa kwe sodium carbonate tsvina muchigadzirwa kunoderedzwa kubva ku2.4% kusvika ku0.3%. Iyo yekutonhodza maitiro inoitwa munzvimbo isina kunaka yekumanikidza, iyo inoderedza mukana weiyo sodium hydrosulfide inosangana nemhepo uye nekuita oxidation, zvinobudirira kudzivirira kuparara kwechigadzirwa. Kushandiswa kwegadziriro yakazara yakavharwa yekucheneswa kwe sodium hydrosulfide inovimbisa kuti hapana magasi anogumbura anoburitswa panguva yekuita, kudzivirira kusvibiswa kwechipiri kune zvakatipoteredza. Iwo sodium hydrosulfide mapepa akaiswa mabhegi zvakananga, kudzivirira kusvibiswa panguva yekuchengetedza. Pamusoro pezvo, chigadzirwa ichi chine nzira iri nyore, inoda michina mishoma, uye ine mutengo wakaderera.
