Training Introduction

Delayed coking is a critical thermal conversion process that transforms heavy refinery residues into high-value lighter products and marketable petroleum coke. Mastering delayed coking operations requires a deep understanding of furnace dynamics, fractionator controls, and complex coke-drum cycles to prevent costly operational disruptions such as tube fouling or liquid carryover.

Participating in a specialized Delayed Coking Unit Operations Training Course equips refinery professionals with the actionable expertise required to maximize conversion efficiency, ensure unit reliability, and maintain strict product quality standards.

Key focus areas of this course:

  • Understanding thermal cracking chemistry and feedstock property impacts
  • Managing coker furnace operation and preventing tube coking
  • Controlling coke-drum filling, stripping, quenching, and hydraulic decoking cycles
  • Optimizing main fractionator conditions, wash-zone operations, and heat balance
  • Preventing foam formation, liquid carryover, and equipment fouling
  • Applying proactive troubleshooting techniques during drum switching and start-up activities

What are the goals?

This specialized training course is engineered to provide engineers and operational personnel with full practical mastery over delayed coking operations. Participants will develop the analytical and practical skills necessary to optimize unit throughput, enhance product recovery, and enforce stringent safety protocols across every stage of the coking cycle.

  • Explain fundamental delayed coking chemistry, reaction mechanisms, and feedstock impacts
  • Evaluate the effects of vacuum residue properties on operating parameters and product yields
  • Master the operational principles of coker furnaces, coke drums, and main fractionators
  • Manage coke-drum filling, steam stripping, water quenching, and hydraulic decoking safely
  • Optimize furnace burner operation, heat distribution, and steam injection rates to reduce fouling
  • Diagnose and resolve operational challenges in fractionators, gas-recovery, and coke-handling systems

Who is this Training Course for?

This Delayed Coking Unit Operations Training Course is specifically tailored for engineering, technical, and operational personnel seeking to improve unit performance, safety, and mechanical integrity within refinery operations. It offers immense practical value for both frontline staff and engineering teams focused on process optimization.

  • Delayed coking unit operators, shift supervisors, and production staff
  • Refinery process, operations, and technical service engineers
  • Process control, instrumentation, maintenance, and reliability engineers
  • Mechanical integrity, inspection, and asset-management specialists
  • Laboratory technicians and product-quality control personnel
  • Health, safety, and environmental professionals managing refinery processing units

How will this Training Course be Presented?

This Delayed Coking Unit Operations Training Course is delivered through a highly practical and interactive methodology, blending expert-led technical presentations with clear process flow diagrams, equipment schematics, and operational data evaluations. Participants actively engage in real-world refinery case studies, process calculations, and interactive troubleshooting exercises that simulate complex operational scenarios.

Throughout the training, delegates are encouraged to examine everyday unit challenges, analyze operational variables, and formulate effective corrective and preventive strategies. Group discussions and interactive feedback sessions ensure that concepts are thoroughly understood and directly adaptable to each participant's workplace environment.
