ESS Thin-Film Evaporation Pilot Plant Educational Lab Equipment Chemical Engineering

Description

ESS Thin-Film Evaporation Pilot Plant Educational Lab Equipment Chemical Engineering

This evaporator consists of a cylindrical tube provided with a steam heating jacket and with a three-blade inner rotor that produces a very thin film of liquid on the walls.

TRAINING PROGRAM

This unit enables to deepen the following issues:

• Mass balances
