Yadda za a cire ruwa bayan 4A kwayoyin sieve dehydration

2022-12-30

Ruwan ruwan siffa ta kwayoyin halitta ya dogara da abun ciki na ruwan samfurin, jagororin kawar da ruwa na 4A.

1. Amfani: 4A kwayoyin sieve yana da zaɓin adsorption damar kuma zai iya cire danshi a cikin abubuwan da ake amfani da su na kwayoyin halitta da gas, amma ba ya yada kaushi da gas (kamar tetrahydrofuran).Hanyar asali tana ɗaukar ƙarancin soda mai narkewa, caustic soda yana narkewa cikin ruwa, ba shi da sauƙin rabuwa tare da tetrahydrofuran bayan bushewa, yana amfani da soda mai wahala don sake amfani da shi, a zahiri ya karu farashin.

2. Hanyar aiki: Aikin bushewa na 4A simin kwayar halitta yana da sauƙi.Za a iya shigar da sieve na kwayoyin kai tsaye a cikin kawar da sauran ƙarfi, ko kuma ana iya wuce maganin da iskar gas kai tsaye ta hasumiya mai tallata ƙwayoyin ƙwayoyin cuta.

3. Adsorption iya aiki: Molecular sieve 4A yana da in mun gwada da girma adsorption iya aiki, kullum 22%.

4. Zaɓin aikin adsorption: 4A na'ura mai kwakwalwa na iya ɗaukar kwayoyin ruwa cikin sauƙi.Saboda diamita na kwayoyin ruwa ya fi na zeolite, za a iya samun ma'auni na electrostatic bayan adsorption (Sieves na kwayoyin ba sa shafe barbashi tare da diamita mafi girma fiye da na kwayoyin sieves).

5.Analysis ba tare da samar da ruwa: 4a kwayoyin sieve ba za a saki bayan sha ruwa a dakin zafin jiki.

6. Sabuntawa: Sabuntawar 4A kwayoyin sieve yana da sauƙi.Bayan sa'a daya, za a iya sake amfani da nitrogen sama da 300 ° C (abubuwan da ba za su iya ƙonewa ba za a iya zuga su kai tsaye zuwa cikin iska).

7. Long sabis rayuwa: 4A kwayoyin sieve za a iya sake farfado da 3-4 shekaru.

Siffofin kwayoyin halitta suna da ƙarfi hygroscopicity zuwa danshi, don haka ya kamata a yi amfani da su don tsarkakewar iskar gas kuma ya kamata su guje wa hulɗar kai tsaye tare da iska.Ya kamata a sake farfado da sieves na kwayoyin halitta wadanda suka sha danshi bayan an adana su na dogon lokaci.Siffofin kwayoyin suna guje wa mai da ruwa mai ruwa.Yi ƙoƙarin kauce wa haɗuwa da mai da ruwa mai ruwa yayin amfani.Gas don bushewa magani a cikin samfuran masana'antu sun haɗa da iska, hydrogen, argon, da dai sauransu. Ana haɗa busassun adsorption guda biyu a layi daya, ɗayan yana aiki kuma ɗayan na iya sake haɓakawa.Don ba da damar ci gaba da aiki na kayan aiki, suna canzawa da juna.Na'urar bushewa tana aiki a yanayin zafi na yau da kullun, kuma yana yin sabuntar iska a yanayin zafi sama da 340°C.

Tsari da ka'ida na rashin ruwa mai narkewa

Rashin ruwa shine tsarin tallan jiki.Ƙarfin iskar gas yana faruwa ne ta hanyar ƙarfin Fan ko ƙarfin watsawa.Adsorption na iskar gas yayi kama da narkar da iskar gas.Gabaɗaya ba zaɓi ba ne kuma tsari ne mai juyawa.Zafin adsorption yana da ƙananan kuma ƙarfin kunnawa da ake buƙata don ƙaddamarwa yana da ƙananan, don haka saurin haɓakawa da sauri, sauƙi don cimma daidaito.
