Absorbers - Visual Encyclopedia of Chemical Engineering

General Information/Equipment Design. Stirred tanks, also called agitated tanks or CSTRs, are used when the absorption process includes a slow liquid-phase chemical reaction, or when close control of the process is needed. In a stirred tank, the gas is introduced directly into the liquid and mixed by the stirrer. The solids are suspended.

Spray Dryer Design

The most important variables in the design of a spray dryer are the evaporation rate and the required particle size distribution of the product. The evaporation rate and the dryer ΔT (inlet air temperature minus the outlet air temperature) dictates the amount of drying air needed, which dictates the sizing and cost of almost all of the system ...
