APC - Polynaphtha

APC uses a model-based predictive control technology that drives the process towards the desired targets through the manipulation of several variables simultaneously while observing all process constraints. APC has a proven track record in delivering business objectives: reducing energy costs, increasing yields and improving operability.

As a process licensor, catalyst manufacturer and advanced control technology supplier, Axens Horizon combines all the necessary expertise for successful Polynaphtha APC projects.

Our control strategy for Polynaphtha consists of:

  • selective hydrogenation (Alkyfining)
    • Respect specifications for diolefins and acetylenics in effluent: Butadiene (BD) & MAPD
    • Limit olefin  hydrogenation
    Polynaphtha reactors
    • Monitor individual ΔTs
    • Control global ΔT for olefins conversion and Gasoline/Distillate (G/D) ratio
    • Optimization of recycle rate
    Debutanizer and Splitter columns
  • Minimization of the reboiler duty to achieve product separation through the control of the internal reflux ratio (IRR).
