ROMeo Delayed Coker Unit Reactor ModelSimSci™ Delayed Coker Unit (DCU) Reactor model is one of the reactor models for Refinery Modeling in the industry-leading ROMeo® Online Performance Suite. Delayed coking is a thermal cracking process used in petroleum refineries to upgrade and convert petroleum residuum into high value liquid and gas streams. Accurate modeling of delayed coking units can help refiners extract maximum value from less costly heavy crudes. The DCU Reactor model can be utilized to model accurate industrial delayed coker units of different designs.

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.
