Goal(s)

Learning outcomes:

  • To understand mass transfer processes between two phases;
  • To master the writing of mass balance without reaction;
  • To design closed and open mass exchangers;
  • To apply the knowledge acquired in the course on two fields of application: gas / liquid absorption without reaction and liquid / liquid extraction.
