Tukanga

Ataata

Ka whakamahia e te Hangarau Whakangao Waiwai Te Methanol me te wai hei rauemi mata, ka huri i te methanol ki te hau whakauru na roto i te whakakorikori me te pure i te hauwai na roto i te pehanga swing adsorption (PSA) i raro i tetahi pāmahana me te pehanga.

Nga Ahuatanga Hangarau

1. Te whakauru teitei: te taputapu matua i raro i te 2000Nm3/h ka taea te paheke ka tukuna katoatia.

2. Te rereketanga o nga tikanga whakamahana: whakawera whakawera whakawera; Whakawera-whaiaro rewharewha tohanga hau whakawera; Te wera hinu whakawera hinu hinu whakawera; Whakawera hiko whakawera wera whakawera hinu.

3. He iti te kai methanol: te iti rawa o te kai methanol o te 1Nm3Ko te hauwai ka kiia he <0.5kg. Ko te mahi tuturu ko te 0.495kg.

4. Te whakaoranga o te kaha o te wera: te whakanui i te whakamahinga o te kaha o te wera me te whakaiti i te tuku wera ma te 2%;

(1) Kapiti Methanol

Whakaranuhia te methanol me te wai i roto i tetahi ohanga, pehi, wera, whakangohu me te whakawera i te rauemi ranunga kia tae ki tetahi pāmahana me te pehanga, katahi ka puta mai te whakakorikori, te tauhohenga methanol cracking me te tauhohenga huringa CO ka mahi i te wa ano, ka whakaputa he ranunga hau me H2, CO2me te iti o te toenga CO.

Ko te hangai Methanol he tauhohenga waahana maha uaua me nga tauhohenga hau me nga tauhohenga matū totoka

Tauhohenga nui:

CH3OHjtCO + 2H2– 90.7kJ/mol

CO + H2OjtCO2+ H2+ 41.2kJ/mol

Tauhohenga whakarāpopototanga:

CH3OH + H2OjtCO2+ 3H2– 49.5kJ/mol

 

Ko te tukanga katoa he tukanga endothermic. Ko te wera e hiahiatia ana mo te tauhohenga ka tukuna ma te tohanga o te hinu kawe wera.

Hei whakaora i te kaha o te wera, ko te hau ranunga ka puta i roto i te reactor ka huri te wera me te wai ranunga rauemi, ka whakamatao, ka horoia ki te pourewa purenga. Ka wehea te wai ranunga mai i te whakamahana me te horoi horoi i roto i te pourewa purenga. Ko te hanganga o tenei ranunga ko te wai me te methanol te nuinga. Ka whakahokia ki te taika rawa mo te hangarua. Ka tukuna te hau kapiti tohu ki te wae PSA.

(2) PSA-H2

Ko te Pressure Swing Adsorption (PSA) e ahu mai ana i te urunga tinana o nga ngota ngota hau i runga i te mata o roto o te adsorbent motuhake (mea totoka maiengi). He ngawari te whakauru o te adsorbent ki te whakauru i nga waahanga kohua nui me te uaua ki te whakauru i nga waahanga iti-kohua i te pehanga kotahi. Ko te nui o te adsorption ka piki ake i raro i te pehanga teitei me te heke i raro i te pehanga iti. Ka whiti te hau whangai i roto i te moenga whakauru i raro i tetahi pehanga, ka kowhiria nga poke e koropupupuu nui ana, ka puta te hauwai iti-kohua e kore e ngawari ki te uru. Ko te wehenga o te hauwai me nga wahanga poke ka kitea.

I muri i te tukanga adsorption, te adsorbent desorbs te poke whenumi i te whakaiti i te pēhanga kia taea ai te regenerated ki adsorb me wehe ano poke.
