DC-SIM™
The KBC SIM Suite Model for Delayed Coking
D
elayed coking is used in many
refineries to convert
residual
streams to useful products. DC-SIM lets
you operate this unit more effectively, by
allowing you to predict coker yields and
product qualities for all your feedstock
possibilities, coke drum temperatures
and recycle rates options.
Feedstock may be atmospheric
residuals, vacuum residuals, or FCC
slurry. The simulation includes the
furnace, drums, main fractionator, and
the drum vapour quenching system.
Cycle time (drum fill time) and resulting
coke qualities are predicted.
DC-SIM is one of KBC’s SIM Suite reactor
models, proven in decades of use by
refiners worldwide.
BENEFITS
• Determine the yields for residual feeds from
different available crudes and the yield shift as
increasing amounts of vacuum gas oil are removed
in the vacuum tower
• Find the coke fill time with different feeds, feed rates,
drum temperatures, and recycle rates
• Generate a consistent set of yield vectors for the LP,
accurately reflecting the feeds from different available
crudes
• Determine the most profitable operation of the delayed
coker given its constraints (heater, coke product
properties, pump and compressor capacities)
• Train engineers and operators new to delayed coking
by using the model to illustrate cause and effect
through simulation runs
DC-SIM is a valuable tool to evaluate different crudes and
their resulting coking yields on this key refinery process
unit.
FEATURES
• Simulation of each coker component – furnace, drum
and main column
• A first-principles, kinetic approach in modelling the
key cracking and coke formation reactions and their
heat effects
• Rigorous heat balance accounting for furnace heat
input, heat rejection (column pump arounds) and
quenches
• Detailed yields and product properties
• Ability to simulate furnace feed configuration with or
without recycle
• A built-in optimiser allows you to identify the most
profitable operation given feed/product pricing,
energy costs, and unit constraints
INTERFACE OPTIONS
DC-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.
DC-SIM AND PETRO-SIM
DC-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 DC-SIM as part
of a complete refinery, at a level of detail unsurpassed
by any other process simulation package.
DC-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.
