Product Detail

1.Ethanol kuomesa ne molecular sieves
Mvura uye ethanol inoumba azeotrope iyo inogadzirisa kuti yakawanda sei mvura inogona kubudiswa neyakajairwa distillation.
Iyo Vogelbusch molecular sieve system inobvumira kupera mvura kwe ethanol yapfuura 95% kuchena.Inobvisa mvura kubva musanganiswa we ethanol/mvura mhute inobuda mukoramu yekugadzirisa kuti iwane chigadzirwa chisina mvura.Kuoma kwechigadzirwa ichi kunogona kugadzirwa kuti zvienderane nezvinotsanangurwa - chero kubva kubioethanol ine mvura inokwana 0.5 % kusvika super yakaoma ethanol yemishonga kana yeindasitiri yekushandisa ine mvura inokwana 0.01 % kana isingasviki.
Zvigadziro zvekugadzira
Zvichienderana nemamiriro eiyo hydrous ethanol feedstock uye kuvapo kwechinwiwa chedoro distillation chirimwa, kune maviri akasiyana magadzirirwo esarudzo yeiyo dehydration unit: yakabatanidzwa kana kumira-yega.

2.Integrated drying units for vaporous feed
Akabatanidzwa kune distillation uye anogashira hydrous ethanol vapors zvakananga kubva pakugadzirisa column.Kuvandudzwa, kana kuchenesa, rukova kunodzoserwa kune distillation kuti idzorerwe ethanol.
Mukana mukuru weiyo yakabatanidzwa sisitimu kudzikisira kwakanyanya mukushandiswa kwesimba kana ichienzaniswa neasina kubatanidzwa masisitimu.Simba-rinoshanda rinopisa kupisa kusanganisa kwe dehydration / rectification / evaporation - a proprietary system yakaunzwa neVogelbusch - zvakare inoderedza mutengo wemari.
Kudyisa kunoda hushoma kudzvanywa kwe 0.5 barg.

Mayuniti ekuomesa ega ekudya kwemvura
inoshandiswa kune hydrous ethanol liquid kubva mukuchengetedza.Iyo hydrous ethanol inonyungudutswa mune diki recycle column.Kuvandudza, kana kuchenesa, rukova runodzoserwa kune recycle column kuti iwanezve ethanol.
Iko kushandiswa kwesimba kwe ethanol drying unit kunodzikiswa neyakakwana dhizaini yekudzoreredza kupisa pasi pekufunga nezve feedstock uye utility mamiriro.
Process musimboti
Molecular sieve dehydration inoshandisa adsorption process uchishandisa synthetic zeolite, crystalline, ine porous zvinhu.Maitiro acho akavakirwa pamusimboti wekuti zeolite's affinity yemvura inoshanduka pane dzakasiyana dzvinyiriro.Kurodha kwemvura yezeolite kunoenderana nekudzvanywa kwechikamu chemvura mune chikafu chinogona kukanganiswa nekuchinja kudzvanywa.

TEG Dehydration Process |Gasi Dehydration System
Muindasitiri yekugadzira oiri negasi, vashandi vezvidyarwa vanogara vachifunga kuti vangabvisa sei zvinosvibisa uye kuendesa yakanakisa kuchena zvigadzirwa.Chinhu chikuru chisingadikanwi chinosvibisa chakabatana negasi rechisikigo imhute yemvura.Kubvisa hunyoro husingadiwi kubva kugasi rakawanikwa, vagadziri veindasitiri vanoshandisa nzira dzakasiyana dzekubvisa gasi, kusanganisira triethylene glycol maitiro.
Chii chinonzi TEG Gasi Dehydration Unit?
A triethylene glycol (TEG) gasi dehydration system is setup inoshandiswa kubvisa mhute yemvura kubva kuchangobva kudzoserwa gasi rechisikigo.Mudziyo wekuomesera uyu unoshandisa mvura inonzi triethylene glycol sechinhu chinopedza mvura mumuviri kuburitsa mvura kubva murukova rwegasi rechisikigo rinoyerera pamusoro payo.Kubatsira kukuru kwekushandisa TEG dehydration unit kugona kudzokorodza mvura yekuomesa kakawanda isati yatsiviwa.
Zvikamu zveGlycol Dehydration Unit
Kuti iite nemazvo basa rayo rekuomesa gasi rechisikigo, glycol dehydration unit inofanira kunge iine zvimwe zvakakosha zvikamu.
Izvi zvakakosha zvikamu zve glycol drying setup zvinosanganisira:
☆ Inlet scrubbers
☆ Bata shongwe
☆ Reboilers
☆ Kuvhiya matangi
☆ Flash separator
Nepo izvo zvikamu zviviri zvekutanga zvakakosha pakuomeswa kwegasi rechisikigo, izvo zvitatu zvekupedzisira zvinonyanya kushandiswa kudzoreredza iyo glycol kubatsira kuwedzera kutenderera kwegasi kupera mvura.

Iyo TEG Gasi Dehydration Unit Inoshanda Sei?
A TEG dehydration unit yakabatanidza magasi ekuomesa magasi ane glycol regeneration process.Kutanga, gasi rechisikigo rakavhenganiswa nemhute yemvura inofambiswa kuburikidza neyekudya gasi inlet pane gasi scrubber, kubvisa mvura yemahara yakabatana nayo.Izvi zvinobvisa yakawanda yemvura yakaturikwa murukova rwegasi pamwe nekusachena kwepachena uye mahydrocarbon emahara.Nekudaro, iro gasi rechisikigo panguva ino richiri kunzi "rakanyorova" uye rinofanirwa kuomeswa zvakare.
Zvadaro, gasi rinopfuudzwa kuburikidza nekubatanidza migero kune shongwe yekubatanidza, apo chikamu chekupedzisira chekuomeswa chinoitika.Iyo yakajairwa yekusangana shongwe inoumbwa neakanyatso kurongeka mazinga ane hunyoro-isina kana "akaonda" mvura glycol.Gasi remusikirwo rinowanzounzwa kuburikidza neinopinza pazasi peiyo shongwe yekusangana uye inosimuka nepakati payo uchigara uchisangana ne glycol fluid pamatanho akasiyana.Chero hunyoro hwakasara mukati megasi hunodhonzwa kubva pairi sezvainokwira kumusoro kwekoramu, uko nzira yekubuda yakamirira kuitisa gasi richangobva kuomeswa kumatangi ekuchengetedza kana kumwe kugadzirisa.Kunyange izvi zvichiitika, iyo glycol mhinduro iri mukati meiyo shongwe yekusangana inova "yakapfuma" sezvo ichitora hunyoro ichida kuvandudzwa kwayo.Nepo yakaoma glycol iri kudyiswa mukati mekuita neimwe inlet, wet glycol iri kubviswa neimwe nzira yekubuda uye inoendeswa kune yekuzvarwa patsva.
Maitiro ekugadziridza maonda glycol anotanga apo "nyoro" glycol inoiswa munhanho-nhatu yekupenya inoparadzanisa yakabvisa yakaunganidzwa mhute yemvura, tunhu tutsvina, uye mafuta.Izvi zvinosvibisa zvinoendeswa kumatangi ekuchengetera kuti gare gare kubudisa tsvina-isina glycol inoendeswa kune reboiler unit.
Iyo reboiler inoparadzanisa mvura yakatorwa kubva ku glycol ne distillation.Mvura inofashaira pa212oF, ukuwo panovira glycol i550oF.Ethylene glycol ichatanga kudzikisira pa404oF, saka vazhinji vanoshanda vanochengeta maitiro avo edistillation pakati pe212oF ne400oF.Chero mvura yakasara mukati me glycol inobviswa semhunga, uye iyo "yakaonda" kana yakaoma glycol ikozvino yagadzirira kudzoserwa kune yekusangana tower kuti iwedzere gasi remvura kupera mvura.

Zvikonzero Zvokubvisa Mvura Yemvura kubva Gasi Rakasikwa
Kuchengetwa kwehuputi hwemvura mukati megasi rechisikigo kunobatanidzwa nekuvhiringidza kune zvese zvekugadzira michina uye kunaka kwegasi pachayo.Zvikonzero zvakakosha zvegasi dehydration zvinotsanangurwa pazasi:
☆ Kuchengetedzwa mwando kunokonzeresa kukurumidza kuora kwemapombi ekufambisa gasi uye midziyo yekuchengetedza.Gasi kupera mvura mumuviri kunodzivirira kuita oxidative pakati pemvura nesimbi pombi.
☆ Kudzivirirwa kwe hydrate kuumbwa kunoderedza mikana yepombi plugging uye / kana kukukurwa.
☆ Kubviswa kwetsvina iyo inogona kushandura gasi mhando inopihwa kune akasiyana maitiro akabatana
☆ Kubviswa kwemhute yemvura kubva kugasi rechisikigo kunonatsiridza kukosha kwayo kwekudziya, kuchiita kuti ive yakasimba nzira yesimba mukupisa.
☆ Kubviswa kwehunyoro kubva kugasi rechisikigo rinofambiswa kuburikidza nemapombi ekufambisa zvakare kunodzivirira kuumbwa kwemaslugs anokonzera vibrational uye mechanic strains zvichikonzera kupera kwavo nekukurumidza uye kuparara.
Natural Gasi Dehydration process
Natural gasi dehydration inogona kuwanikwa nemaitiro akasiyana, kusanganisira anotevera:
☆ Triethylene glycol (TEG) kupera mvura mumuviri
☆ Adsorption uchishandisa yakasimba sorbents
Nepo nzira dzese dziri mbiri dzinogona kushandiswa kunyatsoomesa gasi rechisikigo, dzinosiyana mumidziyo uye matekiniki anoshandiswa kuwana kupera simba.TEG dehydration inoshandisa mvura yepakati (triethylene glycol) kudhonza hunyoro kubva mugasi chaiwo, nepo adsorption inoshandisa yakasimba desiccant zvinhu kubvisa unyoro hunoenderana neyakagadzirwa gasi.
