Gas
Only a moderate gas yield which is well within most refinery capabilities.

Tops
The straight run tops are suitable for gasoline blending and have a higher than average RON with a considerably lower benzene content than Brent crude making it an excellent gasoline component.

Naphtha
Heavy naphtha is of excellent quality as reformer feedstock. The high naphthene content of the heavy naphtha indicates that it is an excellent feed for catalytic reformers and will provide excellent yields and superior reformate quality including high hydrogen yield when reformed.

Kerosene
Low sulfur content, low freeze point, and acceptable smoke point of DUC kerosene indicates that it is very good for Jet A1 production. The jet is limited by boiling point which allows for maximizing jet production. Alternatively, the kerosene can be used for diesel manufacture. If used for diesel manufacture, it is an excellent blend component because of its excellent fluidity properties and low sulfur content.

Gas Oil
Cold flow properties of the atmospheric gasoil make it suitable for the manufacture of automotive diesel meeting both European and North American requirements. Through blending and, in Europe, the use of cetane improvers, this fraction produces high quality automotive gasoil. If used for industrial gasoil, its density and cetane properties make the blend ideal for producing industrial gasoil when winter demand is high. The gasoil is low sulfur.

Vacuum Gas Oil
The VGO is very good as feed to catalytic conversion units which can convert the VGO to high value transportation fuels. Through blending and the use of cetane improvers, this fraction produces high quality auto-gas oil. Also, its density and cetane properties make the blend ideal for producing industrial gasoil when winter demand is high. The gas oil is low sulfur.

Fuel Oil
The atmospheric residue is low in sulfur, metals, pour, and viscosity making it ideal for fuel oil manufacture. Premium low sulfur fuel oil with <0.5 wt% sulfur can be produced using minimal diluent, if any, to meet viscosity specifications.

Residues
The long residue (also know as atmospheric resid) from DUC has low levels of sulfur, metals, asphaltenes, and carbon residue (MCR). Therefore it is an excellent feed for thermal cracking, visbreaking and cokers. It is of sufficiently good quality that it could be fed directly to a fluid catalytic cracker. If fed to a vacuum distillation unit to separate the VGO from the vacuum residue (VR), then it is of such an excellent quality that it could be especially attractive to those refiners who are capable of distilling very deeply to extract the extra heavy VGO from the VR which can be fed to cracking units for conversion to high value transportation or industrial fuels. The VGO from DUC is ideally suited as feed to both catalytic crackers and hydrocrackers.

The yield of 1050ºF/565ºC vacuum residue (VR) is only 9% from crude making DUC an attractive raw material for those refiners without residuum conversion facilities.
