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.
