Hydrorefining

The target of Axens Solutions' Hydrorefining technology is the production of a wide choice of suitable lubricant base stocks from a variety of crude sources. Very similar to the hydrocracking process regarding operating conditions, it uses a special amorphous catalyst having a dual function (hydrotreating and cracking).

The production of lube oils with Viscosity Index (VI) values between 95 and 145 is associated with a conversion to lighter fractions between 20 and 60 wt%.

Lube Oil Hydrorefining

The hydrorefining/hydrocracking scheme for lube base oil manufacturing has many advantages over the conventional solvent process scheme:

Higher flexibility
Higher yields of high-value, high-quality lube base oils
Higher viscosity index: between 95 and 145
Production of high-quality fractions: gasoline, jet and diesel fuel
No wax production

Gradings

Speciality Bed Topping

In Hydroprocessing reactors, pressure drop is mainly induced by particulates build-up and gum formations. Pressure drop not only affect the capacity of the unit but can also have detrimental impact on the distribution.

Gradings

Silica Management

Silicon is a well-known widespread poison for hydroprocessing catalysts. The main contributor to silicon is the Delayed Coker. In addition, there is a general tendency in the oil production industry to use more silicon-based flow improvers.

Gradings

Nickel & Vanadium Management

Nickel and vanadium are naturally present in Crude Oil and usually in fractions boiling over 500°C. Nickel and vanadium poisoning affect only VGO and resid hydrotreaters and hydrocrackers.

Gradings

Gums & Polymer formation control

Pressure drop induced by gum formation is frequently encountered in unit processing some cracked feedstock derived from various conversion processes. The olefins and mainly the diolefins contained in these streams tend to polymerize and get oxidized forming a crust which deposit in the upper layers of the reactor.

Gradings

Arsenic Management

Arsenic is by far the most severe poison for Catalysts. Arsenic maximum allowable content on hydroprocessing catalysts during operation, depending upon the service, is in the range of hundreds of wppm.
