Analiza toplotnih razmer v reaktorski posodi za pridobivanje zeolita = Analysis of heating condition in a zeolite production reactor
Sagadin, Gregor, 1986- ...
V prispevku smo obravnavali proces pridelave zeolita, pri katerem je potrebno zagotoviti homogeno porazdelitev temperature po posodi v nekem določenem časovnem intervalu. V času reakcije zahteva ...proces skoraj popolno mirovanje zmesi, reaktor pa mora biti pri tem segret na določeno temperaturo.Za izpolnjevanje takih procesnih pogojev je bilo potrebno namestiti grelne površine v obliki grelnih cevi v sami reaktorski posodi in uporabiti gretje zunanjega plašča reaktorja. Izvedli smo numerično simulacijo dogajanja v reaktorski posodi za proizvodnjo zeolita in dobljene rezultate primerjali z eksperimentalno dobljenimi rezultati. Numerična analiza je temeljila na uporabi metod računalniške dinamike tekočin (CFD). Rezultati numerične analize problema se dobro ujemajo z eksperimentalno dobljenimi vrednostmi, pri čemer je bila v okviru praktičnih zmožnosti izpolnjena zahteva homogenega ogrevanja v reaktorju oziroma procesni parametri za dosego ustrezne kvalitete zeolita.
