Molecular siievesUa lub luag haujlwm tseem ceeb hauv kev lag luam roj liquefied roj av. Lawv tsis tsuas yog ua lub luag haujlwm hauv kev txhim kho cov khoom lag luam zoo, tiv thaiv ib puag ncig thiab khoom siv tseem ceeb hauv kev txhim kho kev ua haujlwm zoo thiab txo tus nqi.
Daim ntawv thov ntawm molecular sieves hauv liquefied roj av (LPG) tsuas yog suav nrog cov hauv qab no:
1. Kom qhuav thiab desulfurization:
Molecular sieves yog dav siv nyob rau hauv kev ziab thiab desulfurization txheej txheem ntawm liquefied roj av. 13x molecular sieve, tseem hu ua Sodium x molecular sab cib, muaj lub tshuab ua lead ua luaj li 1 nanometer. Piv nrog ntaus cov molecular sab cib, 13x molecular sab cib muaj qhov loj dua vovorption muaj peev xwm ncav cuag tau kom 26%, uas ua tau zoo hauv kev ziab thiab huv.
Hauv kev kho mob ntawm cov nkev roj, liquefied roj av thiab cov kua alkanes (13x molecation lub neej muaj peev xwm tshem tawm cov khoom siv dej hiav txwv, thiab txhim kho kev nyab xeeb thiab ruaj khov ntawm cov txheej txheem ntau lawm.
2. Kev tshem tawm ntawm ya raws thiab sulfide:
Molecular sieves tuaj yeem tshem tawm cov dej noo thiab sulfide hauv kev kho mob LPG, uas yog qhov tseem ceeb rau kev tiv thaiv kev xeb ntawm cov khoom siv hauv dej ntws thiab txhim kho cov khoom lag luam zoo.
Daim ntawv thov ntawm cov mivcular si molecular pab kom tau txais cov khoom lag luam nrog cov ncauj lus tsis huv, thiab tiv thaiv corrosion ntawm cov khoom siv hauv qab daus.
3. Alkylation Reaction:
Molecular sieves tseem siv los ua catalysts rau LPG alkylation cov tshuaj tiv thaiv.
Los ntawm kev npaj tshwj xeeb, molecular sieve catalysts tuaj yeem nce tus nqi hloov pauv thiab siv lub zog rau lub neej thiab ncua kev pabcuam lub neej ntawm cov catalyst.
4. Tshem tawm ntawm cov roj acidic:
Molecular sab cib technology tuaj yeem siv los tshem tawm cov kua qaub acidic xws li hydrogen sulfide (H2s) thiab carbon dioxide (CO2) los ntawm LPG.
Qhov no yog qhov tsim nyog rau cov txheej txheem lim dej ntawm LPG, raws li cov tshuaj acidic twg tuaj yeem txo cov pipeline kis tau zoo thiab corrode pipelines.
5. Lub cev qhuav dej thiab tshem tawm cov pa phem:
Molecular sieves ua lub luag haujlwm tseem ceeb hauv lub cev qhuav dej thiab tshem ntawm cov pa phem nyob hauv LPG.
Lawv tuaj yeem ua kom tshem tawm cov kev paug xws li ya raws, mercapres sulfide, MercAacid sulds thiab carbon dioxide kom tau raws li cov lus qhia zoo tshaj plaws ntawm LPG.
6. Tiv thaiv cov khoom siv hauv downstrream:
Molecular sieves tiv thaiv cov khoom siv hauv qab los ntawm kev ziab cov nkev nce qib rau qib qis dua {}}. 1 ppmv, tiv thaiv kev tsim dej khov thiab ua kom poob siab.
