70 Optimization of Operating Condition of Condensers in UF6 Separation Unit Hadi Share Mohammadi Hadi share@yahoo com Sep 6 2014 Department of Chemical Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language Farsi Email ghoreshi@cc iut ac irSeyyed Mohammad Ghoreishi Prof Abstract In this study optimization of operating condition of two in series UF6 separatorcondensers in UCF unit was performed Modeling and simulation of two condensers wasperformed in other project seperatly In order to use that model for optimization the modelimproved for prediction of the of mist conditions These two shell and tube condenserswere modeled via control volumes with finite length in axial direction of input gases Theequations of mass energy and momentum balance were written for each of the condensers Comparison of the modeling predictions with Isfahan UCF industrial data in regard toimportant variables indicated a very good compatibility The average error between themodeling and industrial data for the first and second condenser were calculated to be 1 39and 2 24 respectively Finally effect of input water temperature and input gas velocityon convective heat transfer coefficient condensed layer thickness condenser efficiency the amount of condensed UF6 and the amount of produced mist were investigated Theobtained results indicated that by increasing water temperature up to 283 K the amount ofcondensed UF6 increased and subsequent higher temperature led to the reduction ofcondensed UF6 The increase of input water temperature reduced the amount of mist andcondenser efficiency The increase of input gas velocity led to the reduction of the amountof mist and the enhancement of the convective heat transfer coefficient condenserefficiency and the condensed layer thickness Finally the analysis of the effective variablesvia the developed modeling computer software revealed that the optimal temperature ofcooling water and the input gas velocity are 10 C and 0 09 m s respectively Key WordsUranium hexafluoride Condensation Condenser Optimization
