Isingeniso Somkhiqizo

Inqubo

I-Hydrogen isetshenziswa kabanzi embonini yensimbi, ye-metallurgy, yamakhemikhali, ezokwelapha, embonini ekhanyayo, ezintweni zokwakha, e-electronics nakweminye imikhakha. Ubuchwepheshe bokuguqula i-methanol ukuze kukhiqizwe i-hydrogen kunezinzuzo zokutshala imali okuphansi, akukho kungcola, nokusebenza okulula. Isetshenziswe kabanzi kuzo zonke izinhlobo zezitshalo ze-hydrogen ezihlanzekile.

Hlanganisa i-methanol namanzi ngesilinganiso esithile, ukucindezela, ukushisa, ukuhwamuka bese ushisa ngokweqile ingxube ukuze ifinyelele izinga lokushisa elithile kanye nokucindezela, khona-ke phambi kwe-catalyst, ukusabela kokuqhekeka kwe-methanol kanye ne-CO shifting reaction yenza ngesikhathi esifanayo, futhi ukhiqize ingxube yegesi ene-H2, CO2 kanye nenani elincane le-CO eyinsalela.

Yonke le nqubo iyinqubo ye-endothermic. Ukushisa okudingekayo kokusabela kunikezwa ngokujikeleza kwamafutha okuqhuba ukushisa.

Ukonga amandla okushisa, igesi eyingxube ekhiqizwe kureactor yenza ukushintshaniswa kokushisa noketshezi oluhlanganisiwe, bese iyajiya, bese igezwa embhoshongweni wokuhlanza. Uketshezi oluxubile olusuka ku-condensation kanye nenqubo yokugeza luhlukaniswa embhoshongweni wokuhlanza. Ukwakheka kwalolu ketshezi oluxubile ikakhulukazi amanzi ne-methanol. Ibuyiselwa ethangini lempahla eluhlaza ukuze igaywe kabusha. Igesi yokuqhekeka efanelekayo ibe isithunyelwa ophikweni lwe-PSA.

Izici Zobuchwepheshe

1. Ukuqina okuphezulu (i-modularization evamile), ukubukeka okubucayi, ukuguquguquka okuphezulu endaweni yokwakha: idivayisi enkulu engaphansi kuka-2000Nm³/h kungenziwa kweqiwa futhi kunikezwe iyonke.

2. Ukuhlukahluka kwezindlela zokushisa: ukushisa kwe-oxidation catalytic; Ukushisa kwegesi ye-self-heating flue; Ukushisa kwamafutha okushisa kwesithando somlilo; Ukushisisa kukagesi okwenziwa ngowoyela wokushisa.

3. Ukusetshenziswa okuphansi kwempahla namandla, izindleko zokukhiqiza eziphansi: ukusetshenziswa okuncane kwe-methanol kwe-1Nm³I-hydrogen iqinisekisiwe ukuthi ingaphansi kuka-0.5kg. Ukusebenza kwangempela ngu-0.495kg.

4. Ukubuyiselwa kwesigaba samandla okushisa: khulisa ukusetshenziswa kwamandla okushisa futhi unciphise ukunikezwa kokushisa ngo-2%;

5. Ubuchwepheshe obuvuthiwe, buphephile futhi buthembekile

6. Umthombo wempahla eluhlaza okufinyelelekayo, izinto zokuhamba ezikahle kanye nokugcinwa

7. Inqubo elula, i-automation ephezulu, kulula ukuyisebenzisa

8. Ayinandaba nemvelo, ayinakho ukungcola

(1) Ukuqhekeka kweMethanol

Hlanganisa i-methanol namanzi ngesilinganiso esithile, ukucindezela, ukushisa, ukuhwamuka bese ushisa ngokweqile ingxube ukuze ifinyelele izinga lokushisa elithile kanye nokucindezela, khona-ke phambi kwe-catalyst, ukusabela kokuqhekeka kwe-methanol kanye ne-CO shifting reaction yenza ngesikhathi esifanayo, futhi ukhiqize ingxube yegesi ne-H₂, CO₂kanye nenani elincane le-CO eyinsalela.

Ukuqhekeka kwe-Methanol kuwukusabela okuyinkimbinkimbi kwe-multicomponent enegesi eminingana kanye nokusabela kwamakhemikhali aqinile

Ukusabela okukhulu:

CH₃OHCO + 2H₂- 90.7kJ/mol

CO + H₂OCO₂+ H₂+ 41.2kJ/mol

Ukusabela okufingqiwe:

CH₃OH + H₂O

CO₂+ 3H₂- 49.5kJ/mol

Yonke le nqubo iyinqubo ye-endothermic. Ukushisa okudingekayo kokusabela kunikezwa ngokujikeleza kwamafutha okuqhuba ukushisa.

Ukonga amandla okushisa, igesi eyingxube ekhiqizwe ku-reactor yenza ukushintshaniswa kokushisa noketshezi oluxubile olubalulekile, bese iyajiya, bese igezwa embhoshongweni wokuhlanza. Uketshezi oluxubile olusuka ku-condensation kanye nenqubo yokugeza luhlukaniswa embhoshongweni wokuhlanza. Ukwakheka kwalolu ketshezi oluxubile ikakhulukazi amanzi ne-methanol. Ibuyiselwa ethangini lempahla eluhlaza ukuze igaywe kabusha. Igesi yokuqhekeka efanelekayo ibe isithunyelwa ophikweni lwe-PSA.

(2) I-PSA-H₂

I-Pressure Swing Adsorption (PSA) isekelwe ekukhangiseni ngokomzimba kwama-molecule egesi endaweni engaphakathi ye-adsorbent ethile (izinto eziqinile ezinezimbobo). I-adsorbent kulula ukukhangisa izingxenye ezibilisa kakhulu futhi kunzima ukukhangisa izingxenye ezibilisa kancane ngengcindezi efanayo. Inani le-adsorption likhuphuka ngaphansi kwengcindezi ephezulu futhi lehla ngaphansi kwengcindezi ephansi. Lapho igesi yokuphakelayo idlula kumbhede we-adsorption ngaphansi kwengcindezi ethile, ukungcola okubilayo kuyakhangiswa ngokukhetha futhi i-hydrogen ebilisa kancane engakhangisiwe kalula iyaphuma. Ukuhlukaniswa kwe-hydrogen nezingxenye zokungcola kuyabonakala.

Ngemuva kwenqubo ye-adsorption, i-adsorbent idonsa ukungcola okumuncwayo lapho inciphisa ukucindezela ukuze ikwazi ukuvuselelwa ukuze i-adsorb futhi ihlukanise ukungcola futhi.
