Nzira yekubvisa sei mvura mushure me4A molecular sieve dehydration

2022-12-30

Molecular sieve kutorwa kwemvura kunoenderana nehuwandu hwemvura yechigadzirwa, 4A molecular sieve yekubvisa mvura nhungamiro.

1. Kushandisa: 4A molecular sieve ine yakasarudzwa adsorption simba uye inogona kubvisa unyoro mu organic solvents uye magasi, asi haadi adsorb solvents uye magasi (akadai se tetrahydrofuran).Nzira yepakutanga inotora caustic soda dehydration, caustic soda inonyunguduka mumvura, haisi nyore kuparadzanisa ne tetrahydrofuran mushure mekushaya mvura, inoshandisa caustic soda kuti iome kudzokorodza, chaizvoizvo yakawedzera mari.

2. Nzira yekushanda: Kupera kwemvura ye4A molecular sieve iri nyore.Iyo molecular sieve inogona kuiswa zvakananga mukubvisa solvent, kana mhinduro uye gasi zvinogona kupfuudzwa zvakananga kuburikidza ne molecular sieve adsorption tower.

3. Adsorption capacity: Molecular sieve 4A ine adsorption yakakura yakakura, kazhinji 22%.

4. Kusarudzwa kwekuita adsorption: 4A molecular sieve inogona kutora ma molecules emvura nyore nyore.Nekuda kwekuti dhayamita yemamorekuru emvura idiki pane yezeolite, electrostatic balance inogona kuwanikwa mushure mekushambadza (mamolecular sieves haatore zvimedu zvine madhayamita akakura kupfuura ayo emamolecular sieves).

5.Kuongorora pasina kubudisa mvura: 4a molecular sieve haizosunungurwi mushure mekutora mvura pakupisa kwekamuri.

6. Kuberekwazve: Kugadziriswa kwe4A molecular sieve iri nyore.Mushure meawa imwe chete, nitrogen inopfuura 300 ° C inogona kushandiswa zvakare (zvinhu zvisingabatike zvinogona kupombwa zvakananga mumhepo).

7. Hupenyu hurefu hwebasa: 4A molecular sieve inogona kuvandudzwa kwemakore 3-4.

Masievha ane hygroscopicity yakasimba kune unyoro, saka anofanirwa kushandiswa pakuchenesa gasi uye anofanirwa kudzivirira kusangana nemhepo.Masefa mamorekuru anenge atora unyoro anofanira kuvandudzwa mushure mekunge achengetwa kwenguva yakareba.Masieve emolecular anodzivirira mafuta uye mvura yemvura.Edza kudzivisa kusangana nemafuta uye mvura yemvura panguva yekushandiswa.Iwo magasi ekuomeswa kwekurapa mune zvigadzirwa zveindasitiri anosanganisira mhepo, hydrogen, argon, etc. Maviri adsorption dryers akabatanidzwa mukufanana, imwe inoshanda uye imwe inogona kuvandudzwa.Kuti vabvumire kuenderera mberi kwekushanda kwemidziyo, ivo vanochinjana mumwe nemumwe.Iyo yekuomesa inoshanda pane yakajairika tembiricha, uye inoita kuchenesa mweya patsva pane tembiricha inopfuura 340 ° C.

Maitiro uye musimboti wemolecular sieve dehydration

Dehydration inzira yekushambadza muviri.Kupinzwa kwegasi kunonyanya kukonzerwa negiravhiti yeFani kana simba rekuparadzira.Iyo adsorption yegasi yakafanana neiyo condensation yegasi.Kazhinji haisarudzi uye inzira inodzoreredzwa.Iko kupisa kweadsorption idiki uye iyo activation simba inodiwa kune adsorption idiki, saka iyo adsorption yekumhanyisa nekukurumidza, nyore kuwana chiyero.
