Mhepo Seperation Unit (ASU)

Tsanangudzo Pfupi

Mhepo yekuparadzanisa unit imhando yemidziyo inotora mhepo seyakabikwa, inoishandura kuita yemvura nekuitsikirira nekuitonhodza kune cryogenic tembiricha, uyezve zvishoma nezvishoma inoparadzanisa okisijeni, nitrogen, argon kana zvimwe zvigadzirwa zvemvura kubva kumhepo yemvura nekugadzirisa. .Zvinoenderana nezvinodiwa nevashandisi, zvigadzirwa zvemayuniti ekuparadzanisa mhepo zvinogona kuve zvigadzirwa zvimwechete kana akawanda zvigadzirwa panguva imwe chete, izvo zvinogona kuva gasi kana mvura.

Product Description

Mhepo yekuparadzanisa unit imhando yemidziyo inotora mhepo seyakabikwa, inoishandura kuita yemvura nekuitsikirira nekuitonhodza kune cryogenic tembiricha, uyezve zvishoma nezvishoma inoparadzanisa okisijeni, nitrogen, argon kana zvimwe zvigadzirwa zvemvura kubva kumhepo yemvura nekugadzirisa. .Zvinoenderana nezvinodiwa nevashandisi, zvigadzirwa zvemayuniti ekuparadzanisa mhepo zvinogona kuve zvimwechete kana akawanda zvigadzirwa panguva imwe chete, izvo zvinogona kuva gasi kana mvura.

Iyo chaiyo muitiro (external compression) ndeiyi: mweya wakamanikidzwa kubva kumhepo compressor, mushure mekubvisa tsvina senge unyoro, carbon dioxide, hydrocarbons uye kumwe kusvibiswa kuburikidza ne molecular sieve, inotumirwa zvakananga kune yepamusoro distillation column, uye imwe chikamu inopinda. the expander.Mushure mekuwedzera, iyo cryogenic air inotumirwa kune yakaderera column.Nekugadzirisa, nitrogen inogona kuwanikwa kumusoro kwekoramu yepamusoro uye oksijeni pazasi kwekoramu yepamusoro.Iyo yakapatsanurwa okisijeni, nitrogen uye gasi rekuburitsa zvinopiswa zvakare neiyo main heat exchanger uye yozoburitswa kubva mubhokisi rinotonhora.Iyo okisijeni kana nitrogen zvigadzirwa zvinobuda mubhokisi rinotonhora zvinomanikidzwa nemacompressor kune yakatsanangurwa kudzvanywa uye inotumirwa kumushandisi.

Zvakanakira

1. Iyo yepamusoro yekuita calculation software inotengeswa kubva kunze kwenyika inoshandiswa kugadzirisa uye kuongorora maitiro echigadzirwa ichi kuti ive nechokwadi chokuti ine zviratidzo zvakanakisisa zveunyanzvi uye zvehupfumi uye chiyero chakanaka chekuita-mutengo.

2. Iyo mhepo yekuparadzanisa unit (main chigadzirwa O₂) inotora yakakwirira-inoshanda condensation evaporator ine kumanikidzwa kuyerera kwemvura inopinza muchikamu chepasi chemhepo yemvura, ichibvumira mweya weokisijeni-inopfumisa kumanikidzirwa kubuda uye kuyerera kubva pasi kuenda kumusoro muiyo condensation evaporator, kudzivirira kuunganidzwa kwehydrocarbon.

3. Kuti ive nechokwadi chekuchengetedzwa uye kuvimbika kwemidziyo, midziyo yose yekumanikidza, piping piping uye zvikamu zvekumanikidza muASU zvakanyatsogadzirwa, zvinogadzirwa uye zvinoongororwa maererano nemitemo yenyika.Iyo ASU inotonhora bhokisi uye pombi mubhokisi rinotonhora zvakapfuura kuverenga kwesimba.

Zvimwe Zvakanakira

Mazhinji einjiniya ari pachikwata chekambani yehunyanzvi akaita nhamba yakakura ye cryogenic ASU magadzirirwo emakambani egasi epasi rose nemakambani egasi epamba.

Tine ruzivo rwakakura mukugadzira ASU uye kuita chirongwa, tinogona kupa nitrogen jenareta (300 Nm.³/h–60,000 Nm³/ h), maASU madiki (1000 Nm³/h–10,000 Nm³/h), uye maASU makuru (20,000 Nm3/h–60,000 Nm³/h).
