Process engineering criteria sizing the vessels

In order to illustrate the sizing of a vessel in a typical case it is convenient to take as an example an extractor used for the extraction of hops with 

The calculation of extractor height and volume for the required production capacity and a trial set of process variables is outlined below, together with relevant data from laboratory and pilot plant tests. 

Extractor (Process types A-C) Separator (Process type A) Adsorber (Process type B) Extraction and absorption columns (Process types C and D) 

Productivity Mass of extract Mass of extract Flow regime/ 

Bulk density Density of extract Bulk density of flooding point Packing/fllling material
