Selection and Design of Extraction Apparatus

The presented order has not to be followed strictly. Sometimes iterative loops are required. 

The optimal apparatus is the apparatus which best solves the extraction problem with minimum investment costs. In Fig. 6-49 the course of the characteristic cost value for different extractor types C, is presented 

Spray column, packed column. sieve tray column 

This is equivalent to the investment costs according to Stichlmair [6.77] for different types of extraction apparatus, over the total throughput.
