SUMMARY
SimSci’s Delayed Coker Reactor Model
provides you with a key component of
the refinery, Delayed Coker Units, within
the ROMeo Refinery Modeling software.
This allows the refinery to be simulated,
onitored,and optimized. Tested and proven on
industrial units, this model allows the flexibility
of tuning parameters online, providing an
accurate representation of your Delayed Coker.
BENEFITS
• Maximize profit by optimizing the DCU feed and operating condition
• Help with understanding the process and relationship between product yields and feed and operating condition
• Debottlenecking and process improvement study
Features The DCU model offers the following key features:• Models the entire delayed coker unit, including the
coke drum and fractionator
• Predicts yields of the three products and key properties for liquid and coke
• Ability to process resid, FCC bottoms (slurry oil) or thermal tar
• Inputs include feed characteristics, coke drum overhead temperature, pressure, and recycle rate
• Three types of products, gases from H2S, H2 , C1 to C4, liquid from C5 up to NBP 1100 °F, and solid coke
• Yields and properties are tunable, during operation, to maintain model accuracy

Applications • Refinery-wide modeling and optimization for
understanding the interaction between the DCU and upstream/downstream units
• Better understanding of the relationship between product yields, feed characteristics, and operating conditions
• Online or Offline DCU performance monitoring and optimization
• Offline engineering and process improvement studies with offline SimSci SIM4ME® Portal Microsoft® interface
ROMeo Refinery Modeling ROMeo Refinery is a unique solution thatenables scalable refinery-wide modeling andoptimization. While traditional modelingsolutions can only simulate individual processunits or provide point solutions to solvea specific problem, the ROMeo OnlinePerformance Suite provides a scalable platformthat enables companies to opt imize refinerywideperformance as well optimize otheraspects of refinery profitability such as Utilitiesand instrument/equipment health monitoring.Additional benefits are derived from leveragingthe data-generated rigorous models toenhanced planning and scheduling decisions,leading to increased refinery margins.
