Kev Txhim Kho Ntawm Siab Swing Adsorption Technology

Kev txhim kho txheej txheem
Lub tswv yim ntawm lub siab viav vias adsorption tau thov los ntawm H. Kahle nyob rau hauv daim ntawv thov patent nyob rau hauv lub teb chaws Yelemees xyoo 1942. Thaum lub sij hawm ntawd, cov adsorbents nws siv tsuas yog silica gel, activated alumina thiab activated carbon. Cov adsorbents no muaj qhov tsis zoo adsorption thiab me me sib cais coefficient rau oxygen thiab nitrogen nrog cov ntsiab lus qis boiling thiab zoo li molecular diameters, thiab nws yog ib qho nyuaj rau cais lawv ntawm ib leeg. Yog li ntawd, txoj kev no tau tsim maj mam ua ntej xyoo 1950. Tom qab, vim yog yug los ntawm zeolite molecular sieves, nws pib siv rau hydrogen purification nyob rau hauv 1958, thiab industrial-scale hydrogen ntau lawm nyob rau hauv 1962. Tom qab nkag mus rau hauv lub xyoo 1970, lub siab viav vias adsorption (PSA) tau tsim sai heev. Nws yog tsuas yog siv rau kev rho tawm hydrogen los ntawm cov pa roj carbon monoxide thiab cov pa roj av, thiab huab cua purification thiab ziab. Nws yog siv ntxiv los cais cov pa oxygen thiab nitrogen gases los ntawm huab cua. Xyoo 1977, Lub Tebchaws Yelemees Essen Mining Co., Ltd. (BF) tau ua tiav cov pa roj carbon molecular sieves siv thee. Tebchaws Asmeskas, Nyij Pooj thiab lwm lub tebchaws tau yuav B. F Lub Tuam Txhab patent mus sim ntau lawm siv cov pa roj carbon molecular sieve siab viav vias adsorption (CMS-PSA) kom cais cov huab cua thiab tsim cov pa oxygen thiab nitrogen. Lub tuam txhab thoob ntiaj teb tseem ceeb uas siv lub siab viav vias adsorption los tsim cov pa oxygen thiab nitrogen los ntawm huab cua suav nrog Linde hauv Munich, Lub Tebchaws Yelemees, Airco hauv New York, Tebchaws Asmeskas, Oxygen Technology Co., Ltd. hauv London, UK, Mangels hauv Sao Paulo, Brazil, thiab lwm yam. Cov khoom siv siab viav vias adsorption tau ua lag luam, thiab cov khoom siv me me thiab nruab nrab siab viav vias adsorption cua cais cov pa oxygen thiab nitrogen ntau lawm tuaj yeem sib tw nrog cryogenic distillation. Union Carbide Corporation (UCC) ntawm Tebchaws Meskas yog nyob rau hauv txoj haujlwm tseem ceeb hauv ntiaj teb hauv kev siv lub siab viav vias adsorption los tsim cov pa roj. Nws tau tsim ntau pua cov khoom siv hydrogen, oxygen thiab nitrogen ntau lawm. UCC tau tsim cov txheej txheem ntau lub txaj (10 mus rau 12 lub txaj) los tsim cov hydrogen nrog purity ntawm 99.999% thiab tus nqi rov qab ntau dua 85%. Lub tuam txhab siv nws tus kheej patented zeolite adsorbent los tsim 99.95% nitrogen thiab 99.5% oxygen. Piv nrog rau cov cuab yeej siv siab viav vias adsorption zoo tib yam, cov cuab yeej no txuag 50% ntawm kev nqis peev thiab txo kev siv hluav taws xob los ntawm 25% mus rau 30%. Southwest Institute of Chemical Industry, Ministry of Industry. Xyoo 1995, Lub Xeev Pawg Saib Xyuas Kev Tshawb Fawb thiab thev naus laus zis tau pom zoo tsim "National PSA Technology Promotion and Application Center" hauv lub koom haum.
