Kernel function such as linear, polynomial and RBF are employed for SVR modelling. The original process data was generated by simulating the batch distillation process, varying the initial feed composition and boilup rate from batch to batch. Within each batch reflux ratio was also randomly changed to represent the true dynamics of the batch distillation. The results show the potential of the method for developing softsensor for chemical processes.</p>10aBatch distillation10acomposition estimation10asoft sensor10asupport vector regression1 aJain, P.1 aRahman, I.1 aKulkarni, B., D.  uhttps://library.ncl.res.in/content/development-soft-sensor-batch-distillation-column-using-support-vector-regression-techniques01206nas a2200229   4500008004100000022001400041245006600055210006500121260008900186300001200275490000700287520045600294653001600750653002300766653001200789653001400801653001200815100002000827700001700847700001700864856009500881       2009                        eng d  a0022-445600aEntrainer for batch distillation of acetic acid -water system0 aEntrainer for batch distillation of acetic acid water system  aDR K S KRISHNAN MARG, NEW DELHI 110 012, INDIAbNATL INST SCIENCE COMMUNICATIONcOCT  a871-8750 v683 a<p>Acetic acid-water system (AW) poses a challenge in reactive distillation, acetic acid purity and loss of acetic acid in aqueous solutions. Feasible separation of AW has been studied using entrainers but acetic acid loss in lean phase cannot be avoided. This study presents feasible region to operate column with toluene and benzene as entrainer for AW. Liquid-liquid equilibrium data and nature of tie line for ethyl acetate are given priority.</p>10aAcetic acid10aBatch distillation10aBenzene10aEntrainer10aToluene1 aGadekar, S., V.1 aNaik, R., V.1 aKaul, S., N.  uhttps://library.ncl.res.in/content/entrainer-batch-distillation-acetic-acid-water-system-0
