APC - Reforming

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 and catalyst supplier, Axens is well positioned to offer models and first-hand knowledge of the best strategies for APC projects.

Our control strategy for CCR Reforming consists of:

• Heaters: Tube Skin temperature and Duty protection
• Reactors
• WAIT control for Octane (or Aromatics)
• Feed maximization and Pressure minimization
• Coke lay-down control by H₂/HC minimization
• Regenerator 
• Coke on catalyst (wt%) control by catalyst flow
• Coke burn balance between the combustion beds
• Stabilizer column
• Reformate RVP control
• Minimization of Reformate losses in top product
• Internal reflux minimization
