N HTR-SIM™
The KBC SIM Suite Model for Naphtha Hydrotreating
H
ydrotreating operations are key
to operating downstream units
effectively and adhering to finished
product regulations. How will various
feeds perform in your hydrotreater with
respect to hydrogen consumption, effect
on ultimate catalyst run length and
product qualities? N HTR-SIM can help
determine the answers.
The N HTR-SIM model combines a
detailed, rigorous kinetic simulation of the
reactor and accurate product separation
to produce the industry’s most trusted
analytical tool for naphtha hydrotreating.
N HTR-SIM is one of KBC’s SIM Suite
refinery reactor models. KBC has the
most complete and detailed set of
refinery reactor models available in the
industry.
BENEFITS
• Determine the best tradeoff of severity versus run
length
• Predict hydrogen requirements for changing
operating conditions and feeds
• Accurately monitor catalyst deactivation and
determine time to shutdown
• Generate a consistent set of yield vectors for different
feeds and severities for use in the refinery LP
• Determine the most profitable operation for a given
hydrotreater unit given pricing for feeds, hydrogen,
products, utilities, and unit shutdown
• Train engineers and operators new to
hydroprocessing by using the model to illustrate
cause and effect through simulation runs
N HTR-SIM is a valuable tool to determine run lengths
with different feeds, monitor deactivation, develop a
consistent set of LP yield vectors and establish more
profitable operations.
FEATURES
• A detailed simulation of the reactor section of the
hydrotreater, including quenches and downstream
flashes, as well as the recycle gas loop
• Rigorous kinetic representation of all key
hydrotreating reactions – HDS, HDN, HDA, olefin
saturation, ring opening and cracking
• Detailed heat balances to allow the calculation
of bed temperature rises and resulting quench
requirements
• Accurate modelling of catalyst deactivation based
on catalyst temperature, hydrogen partial pressure
and feedstock qualities
• Estimation of multiple sulphur species and
separate reaction pathways, providing accurate
representation of naphtha desulphurisation
• A built-in optimiser allows you to identify the most
profitable operation given feed/product pricing,
catalyst costs, and unit constraints
INTERFACE OPTIONS
N HTR-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.
N HTR-SIM AND PETRO-SIM
N HTR-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 N HTR-SIM as part
of a complete refinery, at a level of detail unsurpassed
by any other process simulation package.
N HTR-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.
