Formaldehyde, inogadzirwa kuburikidza ne catalytic oxidation yemethanol, chinhu chakakosha muma resin, adhesives, mapurasitiki, uye mishonga, asi kunyangwe paine kutsauka kudiki mukuwanda kwemethanolkanahuwandu hwe formaldehydezvinogona kutungamira mukuumbwa kwepolymer, kuderera kwegoho, kana kusatevedzera mitemo yakasimba yekuchengetedza.
Masensa ekuyera methanol,mita dzekuyerwa kwe formaldehyde,monitors dzekuwanda kwe formaldehydeuyevanoongorora huwandu hwe formaldehydekupa kutarisa kwakarurama uye kwenguva chaiyo, zvichiita kuti vashandi vemafekitori varambe vachichengetedza mamiriro ekuita zvakanaka uye kuderedza kusashanda zvakanaka kunodhura.
Nhanganyaya Yese yeMaitiro eKemikari
Formaldehyde, kemikari inoshandiswa zvakasiyana-siyana kubva kune zvinonamira zvehuni kusvika kune zvinosanganisa mishonga, inogadzirwa kuburikidza ne catalytic oxidation ye methanol muzvigadzirwa zve formaldehyde. Kuchengetedza huwandu hwe methanol hwakafanana uye huwandu hwe formaldehyde hwakakosha kuti isangane nezvinodiwa zvemhando yepamusoro.
Zvishandiso zvekuongorora huwandu hweMethanol ne formaldehyde concentration analyzers zvinhu zvakakosha kuti zvibudirire pakuita izvi nemazvo. Midziyo iyi inopa data renguva chaiyo, ichibvisa kunonoka uye zvikanganiso zvine chekuita nekutora sampuro nemaoko, uye inobvumira vashandisi kugadzirisa mamiriro ekuita, kuderedza marara, uye kuona kuti mitemo yezvakatipoteredza nekuchengetedza inotevedzwa.
Chemistry uye Maitiro eFormaldehyde Synthesis
Kugadzirwa kwe formaldehyde kunosanganisira catalytic oxidation ye methanol, maitiro akagadziriswa kwemakumi emakore kuti agutse zvinodiwa nemaindasitiri akadai sekugadzira makemikari uye mishonga. Iyi exothermic reaction inokonzereswa nesirivha kana iron-molybdenum, nemethanol vapor yakasanganiswa nemhepo uye inopfuudzwa pamusoro pe catalyst mu reactor.
Formaldehyde inobuda inonyudzwa mumvura, inowanzo gadziriswa ne10–15% methanol kudzivirira polymerization kuita paraformaldehyde. Maitiro aya anoda kudzorwa kwakanyatsojeka kwehuwandu hwemethanol mu feedstock uye huwandu hweformaldehyde mu reactor uye chigadzirwa chekupedzisira kuti ive nechokwadi chekuti goho rakawanda.
Matanho makuru anosanganisira:
Kugadzirira Methanol
Kuve nechokwadi chekuti chikafu chine huwandu hwakakwana hwemethanol yemvura (kazhinji 50–60 wt%) kuti zviite kuti mhinduro ishande zvakanaka.
Kuoxidation
Kudzora huwandu hwemethanol-air ratio uye mamiriro ereactor kuti zviwedzere kugadzirwa kweformaldehyde uye kuderedza zvigadzirwa zvakaita seformic acid.
Kunyudzwa
Kusveta formaldehyde mumvura kuti igadzire formalin, zvichireva kuti zvinoda kuyerwa kwakarurama kwehuwandu hwe formaldehyde kudzivirira polymerization.
Kuchengetedza uye Kugadzikana
Kuisa methanol stabilizers kuchengetedza huwandu hwe formaldehyde uye kudzivirira kuora.
Nei Kudzora Kuisa Mutsetse Kwakakosha
Kuchengetedza chiyero chakarurama che methanol uye chiyero che formaldehyde kwakakosha nekuda kwezvikonzero zvakati wandei. Methanol yakawandisa mu feedstock inogona kukonzera kusakwana kwe oxidation, kuderedza goho re formaldehyde uye kuwedzera marara. Kusiyana neizvi, kusakwana kwe methanol kunogona kukanganisa reaction, zvichideredza kubereka. Padanho rekunyudzwa, huwandu hwakawanda hwe formaldehyde (hunopfuura 50 wt%) hunogona kukonzera polymerization, zvichigadzira paraformaldehyde solids iyo inovhara michina uye inovhiringidza mashandiro.
Nzira dzekare dzekutarisa, dzakadai segasi chromatography kana titration, dzinotora nguva uye dzinowanzo kanganisa, zvichinonotsa kugadzirisa. Masensa ekuyera methanol uye formaldehyde concentration monitors zvinopa data rinogara riripo, zvichibvumira vashandi kugadzirisa feedstock ratios, mamiriro e reactor, uye stabilizer anowedzera ipapo ipapo, zvichiita kuti chigadzirwa chive chakafanana uye chishande zvakanaka.
Inokurudzirwa Lonnmeter Inline Concentration Monitor
Chiyero cheLonnmeter chekuongorora ma ultrasonic concentration chinoshanda nekuyera nguva yekutumirwa kwema ultrasonic waves kubva kunobva chiratidzo kuenda kunogamuchira, zvichireva kumhanya kweruzha kuti zviverenge density uye concentration. Nzira iyi haikanganisike nemabubbles, furo, kana conductivity yemvura, ruvara, kana kujeka, zvichiita kuti ive yakavimbika munzvimbo dzakaoma dzakadai se formaldehyde production plants.
Kusavapo kwezvikamu zvinofamba kunobvisa kusakara kwemuchina, zvichivimbisa kushanda zvakanaka nekufamba kwenguva. Dhizaini yemita iyi isingapindiri inoderedza kugadziriswa, uye zvinhu zvayo zvinodzivirira ngura zvinotsungirira makemikari akasimba, zvichiita kuti ive yakakodzera zvirimwa zvemishonga zvinobata formaldehyde ne methanol.
Maitiro Ekuisa uye Kubatanidza
Kuti zvinyatsoshanda zvakanaka zvevanoongorora huwandu hwe formaldehyde, kuisa kwakakosha. Masensa ekuyera huwandu hweMethanol anofanirwa kuiswa mumitsetse yezvikafu kuti ave nechokwadi chekuti mhando yekupinda inoenderana, nepo formaldehyde concentration metres yakakodzera nzvimbo dzereactor ne columns dzekunyudza kuti dzitarise kugadzirwa kwechigadzirwa nekugadzikana. Masisitimu asina simba anogona kuiswa kuti arambe achishanda panguva yekugadzirisa, zvichideredza nguva yekushanda.
Kubatanidzwa nehurongwa hwekudzora zvirimwa kunobvumira kugadziriswa otomatiki, senge kudzora huwandu hwemethanol feed kana kuwedzera stabilizer, zvichibva pane data renguva chaiyo. Kugadziriswa nguva dzose nemhinduro dzakajairwa kunovimbisa kururama kwekuyera, kunyanya mumamiriro ezvinhu anochinja-chinja ekugadzirwa kweformaldehyde.

Kuvandudza Kushanda Nesimba Kwebasa
Kushandiswa kwemasensa ekuyera methanol pamwe nemamonita ekuyera formaldehyde zvinovandudza kushanda zvakanaka mumafekitori ekugadzira formaldehyde. Nekupa data renguva chaiyo, zvishandiso izvi zvinogonesa vashandisi kuona nekugadzirisa kutsauka kwehuwandu ipapo ipapo, zvichideredza njodzi yekukanganiswa kwemaitiro. Semuenzaniso, kuchengetedza huwandu hwakanaka hwemethanol mumvura muzvikafu zvinodzivirira kusakwana kwe oxidation, kuwedzera goho uye kuderedza marara. Saizvozvowo, kuyerwa kwakarurama kwehuwandu hwe formaldehyde muchikamu chekunyudzwa kunodzivirira polymerization, kuderedza kusvibiswa kwemidziyo uye mari yekugadzirisa.
Mumafekitori epetrochemical, zvishandiso izvi zvinovandudza kushandiswa kwemethanol, zvichideredza mitengo yezvikafu, nepo mumafekitori emishonga, zvinovimbisa kunaka kwepakati, zvichideredza kugadziriswazve. Fungidziro dzeindasitiri dzinoratidza kuti kutarisa mukati mefekitori kunogona kuderedza kushandiswa kwesimba kusvika ku10% uye kuchengetedza nguva yakawanda yekushanda nekuita otomatiki maitiro ekuongorora.
Kuve nechokwadi chekuti chigadzirwa chiri kunaka uye kuti chinotevedzera mitemo
Zvigadzirwa zvakagadzirwa neFormaldehyde, zvakaita seurea-formaldehyde resins uye mishonga yemishonga, zvinofanirwa kusangana nezvinodiwa zvemhando yepamusoro uye zvekuchengetedza. Vaongorori veFormaldehyde concentration vanovimbisa kuti chigadzirwa chekupedzisira (semuenzaniso, formalin) chinochengetedza huwandu hwakakodzera (37–50 wt%) uye huwandu hwe stabilizer, zvichidzivirira kuora uye kuona kuti mashandiro azvo anoshanda zvakanaka mukushandisa senge glues ne coatings.
Mitemo yezvakatipoteredza, inokonzerwa nehuturu hweformaldehyde, inoda kudzora kuburitswa kwemhepo. Mamita emukati anobatsira zvirimwa kutarisa nekuderedza kuburitswa kwemvura yeformaldehyde, zvichideredza njodzi yefaindi uye kuwedzera kuchengetedzeka. Izvi zvakakosha zvikuru muzvirimwa zvepetrochemical, uko kugadzirwa kukuru kunowedzera kukanganisa nharaunda.
Kuchengetedza Mari uye Kukosha Kwenguva Refu
Mabhenefiti emari e formaldehyde concentration metres akakosha. Nekutarisa otomatiki, zvishandiso izvi zvinoderedza mari yevashandi inobatanidzwa nekutora sampuro nemaoko, zvichigona kuchengetedza maawa ekushanda zuva nezuva mumabasa makuru. Zvinoderedzawo marara nekudzivirira kudyiwa zvakanyanya kwe methanol uye stabilizers, zvichivandudza kushandiswa kwe feedstock. Kuchengetedza simba kunowanikwa nekuchengetedza mamiriro ekuita zvakanaka, kuderedza kudiwa kwekupisa zvakanyanya kana kutonhodza muma reactors nema absorption units.
Kugara kwenguva refu kwemamita aya, akavakwa nezvinhu zvisingakanganise ngura, kunoita kuti agare akavimbika kwenguva refu mumamiriro ezvinhu akaoma ekugadzirwa kweformaldehyde. Zvinodiwa zvavo zvekuchengetedza zvishoma uye kubatanidzwa kwavo nemasisitimu ekudzora zvinoita kuti ave mari inodhura zvishoma kumafekitori ekugadzira makemikari nemafekitori epetrochemical anotsvaga kuwedzera purofiti.
Kusarudza sensor ye methanol concentration kana formaldehyde concentration analyzer yakakodzera kunoda kunyatsoongorora zvinhu zvakaita sekururama, tembiricha, nzira yekuisa, zvinhu, nezvimwewo.
