@thesis{thesis, author={Christian }, title ={Preliminary design of salt removal system for Boehmite (AlOOH)}, year={2016}, url={http://repository.wima.ac.id/id/eprint/7543/}, abstract={Washing of boehmite cake is one of the crucial steps in catalyst production process. Understanding and quantification the influence of washing conditions, on purity of washed cake is of high importance. This allows finding the optimal washing conditions for existing processes and optimal design of new ones. In this report, the focus is on developing a correlation that predicts the amount of adsorbed ions (Na+ and SO42-) on boehmite, under certain washing conditions. The proposed correlation is developed based on theoretical insights and its parameters are determined from several sets of washing experiments. To show the applicability of the correlation, a simple Continuous Stirred Tank Washing model is developed. The calculated trends, for example, influence of slurry pH on the amount and type of adsorbed ion is well captured by the proposed correlation.} }
