Flexibility to upgrade a variety of feedstocks to high-quality, lighter products.

The Foster Wheeler Selective Yield Delayed Coking (SYDEC) delayed coking process is a low-pressure, low-recycle coking process for maximum liquid yields and minimizing coke. The process produces a variety of products to suit your operation needs:

  • Gas oil conversion unit feedstocks
  • Distillates
  • Naphtha
  • Petroleum

SYDEC is a full conversion process that can process all types of residues. In combination with VGO Hydrocracking it is the preferred route today for maximizing distillate yields.

The process is exclusively licensed by Foster Wheeler USA Corporation. More than 50 delayed coking plants have been licensed in 37 countries over the past 50 years.
