Why Choose Delayed Coking Unit Operations Training Course?
Delayed coking is a severe thermal conversion process used to upgrade heavy refinery residues into valuable lighter products and marketable petroleum coke. The unit plays an important role in increasing refinery conversion, reducing low-value fuel-oil production and improving overall profitability.
Delayed coking operations involve complex interactions between furnace performance, coke-drum cycles, fractionator conditions, feedstock quality and coke-handling systems. Operational problems such as furnace tube coking, coke-drum foaming, liquid carryover, uneven coke formation, fractionator fouling and delayed drum-cycle changes can restrict capacity and create significant safety and reliability risks.
This Delayed Coking Unit Operations Training Course provides comprehensive coverage of delayed coking process fundamentals, equipment, operating procedures, process control and troubleshooting. It enables participants to optimise unit performance, improve liquid yields and coke quality, reduce fouling, and safely manage coke-drum switching, decoking and start-up activities.
What are the Goals?
By the end of this training course, participants will be able to:
- Explain delayed coking chemistry and process fundamentals
- Evaluate the effects of feedstock properties on unit performance
- Describe the functions of the furnace, coke drums and fractionator
- Manage coke-drum filling, steaming, quenching and decoking cycles
- Optimise furnace operation and minimise tube coking
- Control coke-drum pressure, temperature and foam levels
- Improve liquid yields, coke quality and unit throughput
- Troubleshoot fractionator, gas-recovery and coke-handling problems
- Apply safe operating procedures during drum switching and decoking
- Identify opportunities to improve reliability and cycle duration
