Product Name: APC - Pygas Hydrogenation Services
Product Description
The Pygas advanced control package combines Axens' latest generation
multivariable controller MVAC with on line reactor models, in association with
inferentials; it is designed to maximize the benefits from Pygas process at the
lowest operating cost.
As process licensor, catalyst manufacturer and advanced control technology
supplier, Axens combines all the necessary expertise for successful Pygas APC
projects.
A eight step control strategy
o precise control of product specifications
o adjustment of hydrogen make-up for optimal H2/HC ratio (last reactor)
o control of reactor bed temperature profiles (both reactors)
o control of reactor LHSV (both reactors)
o control of catalyst deactivation
o depentanizer fractionation control
o deoctanizer fractionation control
o compensation of the effects of feed flow variations
On-line reactor model
Assuming on-line styrene analyzer is available for effluent of first reactor,
the Pygas control package uses Axens' SHU reactor models to estimate on-line
diene value (MAV), bromine index, catalyst activity and styrene.
Benefits
o catalyst run length maximization
o ability to absorb more feed flow:
.. no limitation for the upstream plant (ethylene,¡K)
o product on specification at all times
o reduction of hydrogen make up
o reduction of benzene losses in the c5 cut
o safe and proper operation of the unit
o minimization of energy consumption
Company Details
Axens was formed on July 1, 2001 through the merger of IFP's
technology licensing division with Procatalyse Catalysts & Adsorbents. Axens is
a refining, petrochemical and natural gas market focused company offering
market-leading... more
