Case Study

Tuning of expander inlet pressure (3x3 case)

Proper tuning of the expander inlet pressure and feed flows stabilizes the process. The slow cycles in almost all the temperature and pressure loops in chilling section reduced significantly.

Learn in this case study:

  • How AptiTune optimizes a set of 3 interacting PID controllers
  • This stabilization results in a reduction of C3+ in the sales gas from de-methaniser column.
