Delayed coking

Our SYDECSM (Selective Yield Delayed Coking) technology is the leading delayed coking technology due to its robust technical components and our knowledge in delayed coking going back 75 years. We have designed and engineered more delayed coking units world-wide than any other technology provider or engineering contractor. Most delayed coking units are designed today to maximise the production of liquid products and minimize coke production, which is usually fuel grade quality coke. Given our extensive delayed coking licensing and design experience Amec Foster Wheeler has designed units for production of all types of coke: fuel, anode, and/or needle coke.

Our coking capability for new plants and revamps covers a full range of services, from studies, process design packages, FEED, EPC/EPCm, commissioning, start-up and operations assistance, comprehensive training and knowledge transfer with KnowledgeWeb™, design and supply of delayed coking heaters, coke drum replacement and safety improvement, API fitness-for-service evaluation, fatigue life evaluation on coke drums and ongoing licensor support services.

Delayed coking units are complex, and we always recommend Amec Foster Wheeler detailed engineering and critical procurement to realise the full operational benefits of our well-designed, well-constructed delayed coking unit.

The fired heater is the heart of the delayed coking unit. Our fired heaters are a major differentiator that separates our technology from the competition. We have supplied more than 70 delayed coking heaters to 50+ delayed coking units, with single heater capacities ranging from 6,000 to 35,000 bpd, in both single and double-fired configurations.

Key benefits of our technology:
  • Refiners can process heavier, cheaper crudes
  • Complete residue conversion
  • Converts low-value residues to high-value fuels with moderate capital investment
  • Easy integration into existing refinery
  • Safe, reliable and well-proven technology, meeting all regulatory requirements
  • Improved profitability by maximising production of transportation fuels with minimum fuel coke yields
  • Yield selectivity to maximise distillate production
  • Options for calcinable coke production
  • Feedstock flexibility to process residue, pitch, or partially converted material
  • Extended run-lengths between spalling and turnarounds for more on-stream time and lower maintenance costs
  • Designed to maximise operator safety with better layout, improved egress, sophisticated interlocks and automated slide valve unheading.


Amec Foster Wheeler has extensive knowledge and experience in all refining processes and technologies

Fired heaters
