Heat Exchangers


General Objectives:

To enable the participants to understand technology, performance and operation of heat exchangers.

Specific Objectives:

At the end of training the trainees will be able:
  • To have a better knowledge os shell and tube heat exchangers types;
  • To know the heat exchange principles applied to heat exchangers;
  • To be aware of how operating conditions impact on heat exchanger performance;
  • To be able to estimate fouling resistance values and to ptimize the heat exchanger cleaning interval;
  • To manage routine operation safety and know the main steps of start-up, cleaning and testing.
