An experimental simulation of distillation column concentration profiles using a batch apparatus

Experimental simulation of distillation concentration profiles using batch apparatus: Column stripping section

“…(7) are met, the batch profile will follow the distillation column profile. Tapp et al (2003) experimentally confirmed this point. They showed that there is a good agreement between the results given by the ASPEN simulation of a multistage distillation column using the Wilson model and the results obtained by running a batch distillation vessel where they set the initial material composition x F equal to the top stage composition in the continuous column x D .…”

“…Similar to the rectifying section (Tapp et al, 2003) the development and comparison of the continuous distillation and batch distillation equations are essential for the implementation of experimental techniques. The following will present the theory behind both rectifying and stripping profiles.…”

“…Tapp et al (2003) showed that Doherty's rectifying differential equation in a distillation column could be approximated by a time-dependent differential batch equation using a rectifying batch still:…”

“…A combination of computer packages and simple experimental techniques can be a simplification. On the other hand, the costs associated with pilot plants and the poor extrapolation to full scale has led designers not to consider this alternative (Tapp et al, 2003).…”

“…The implementation of the experimental simulation for the distillation rectifying profiles has been presented (Tapp et al, 2003). In this paper, we present a new concept to support the computer simulation of column profiles for the stripping section.…”
