Case Study

APC Implementation for Depropaniser column

The depropaniser column is part of a series of fractionating units for FCC unit. The scope of
APC implementation was to control the top temperature and bottom quality.

Learn in this case study:

  • How APC reduces the interactions between the top and bottom temperatures, so that feed
    changes will not affect the top cut-temp and hence quality.
  • How APC reduces the variation in C3 in bottom to a minimum while maintaining the top quality.
