APC - Selectopol

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 combines all the necessary expertise for successful Selectopol APC projects.

Our control strategy for Selectopol consists of:

  • selective hydrogenation (Alkyfining)
    • Meet Butadiene (BD) specification in the effluent
    • Limit olefin hydrogenation
  • Selectopol reactors
    • Monitor individual ΔT
    • Control global ΔT for n-Butene selectivity maximization
