APC - AlphaButol
APC solution for AlphaButol™ Unit
The AlphaButol advanced control package combines Axens' latest generation multivariable controller MVAC, with on line reactor models, in association with fractionation inferentials; it is designed to maximize the benefits from AlphaButol process, in an environment with complex, slow and non-linear multivariable interactions.
As process licensor, catalyst manufacturer and advanced control technology supplier, Axens combines all the necessary expertise for successful AlphaButol APC projects.
A 4 step control strategy
- Predictive control of Reactor Temperature.
- Incondensable content control in Ethylene Recycle. Optimization of Ethylene purge
- Butene-1 product purity control. Optimization of Recycle Column reboiler duty
- Optimization of Butene-1 Column reboiler duty
dimerization reactor model
The AlphaButol control package uses Axens' Dimerization reactor model to calculate on-line kinetic parameters, used for Reactor Temperature control.
- Increased performance of reactor temperature control
- Ethylene Recycle Purge minimization : - 4 %
- Reboiler Duty minimization (both columns): - 4 %
- Consistent quality of Butene-1 product.
