The KBC SIM Suite Model for Catalytic Reforming
aphtha Reformer operation needs to
respond to current economics and
available feedstocks. What are the best
feeds and severity for your unit, given
hydrogen and octane requirements for
your refinery operation? REF-SIM can
help determine the answers.
REF-SIM accurately models the unit
reactor section, including reaction kinetics
plus all heat balance effects. Yields and
properties of the light ends and reformate
are shown as composite streams by
carbon number and hydrocarbon type
(PIONA) or by individual isomers if
REF-SIM is one of KBC’s SIM Suite reactor
models, proven in decades of use by
refiners worldwide.
• Determine yields, product properties, catalyst life
and hydrogen yields for new/purchased feedstocks
for the reformer
• Generate a consistent set of yield vectors for
different feeds and severities for use in the refinery LP
• Accurately monitor the activity decline of fixed bed
reformers and estimate end-of-run life
• Determine the most profitable operation on a reformer
unit, given pricing for feeds, products and utilities
• Assess data quality, adjust for uncertain measurements
and provide balanced data with REF-SIM’s Data
Reconciliation tool
• Train engineers and operators new to reforming by
using the model to illustrate cause and effect through
simulation runs
REF-SIM is a valuable tool in answering questions
regarding the effects of feed stock properties and
reactor severity on unit profitability.
• Ability to simulate multiple types of reformers: CCR,
semi-regen, and cyclic
• Detailed carbon number feed and characterisation
of C1 - C9 paraffins and aromatics and C1 - C7
naphthenes, plus individual carbon number based
lumps from C8 - C14
• A detailed kinetic scheme incorporating the forward
and reverse rates of all key reforming reactions,
modelling the effects of feed quality, reactor
temperature, and the hydrogen partial pressure on
yields, hydrogen production, and catalyst life
• Flexible feed characterisation mechanisms for data
ranging from distillation and bulk PIONA to detailed
gas chromatograph (GC) analysis
• Designed to match observed yields, octane and
hydrogen production rates for a given set of feed
and operating conditions
• A built-in optimiser allows you to identify the most
profitable operation given feed/product pricing,
catalyst costs, and unit constraints
REF-SIM is available with a Microsoft Excel® based
spreadsheet interface for quick setup, ease-of-use, and
the ability to process multiple calibration and prediction
cases for analysis. Multiple chart options allow easy
analysis of data and model predictions, and concise
summary sheets provide relevant data at a glance.
Excel interfaces are automatically generated and can be
customised to your specific needs.
REF-SIM is also available within Petro-SIM and PetroSIM Express. Take advantage of sophisticated analysis
tools, such as the popular LP Utility for easy generation
and maintenance of LP submodels. Generate detailed
models using downstream separation and auxiliary
units, link with assay and feed libraries and crude units
to investigate feedstock effects, or use REF-SIM as
part of a complete refinery or petrochemical complex,
at a level of detail unsurpassed by any other process
simulation package.
REF-SIM can also be used directly within a graphical
user interface, with the same user-friendly look and
feel as our Petro-SIM family of process simulators.
Make configuration changes using drag-and-drop on
a process flowsheet diagram, compare plant data with
results in a meter view, and perform case studies and
optimisations all within a single environment.
