Flexible operation

Hydrocracking units that meet any market need

Maximizing the heavy naphtha yield from a hydrocracker is advantageous compared to a fluid catalytic cracker (FCC), as light cycle oil (LCO) production is avoided and full conversion can be obtained. Hydrocracking is therefore today the preferred conversion technology for the modern refinery with lower overall investment and operating costs.

A profound understanding of catalyst kinetics and hydrocracking processes enables us to provide hydrocracking units that meet any market need – whether the requirement is maximum heavy naphtha yield, flexible production of high-quality naphtha and diesel or customized seasonal variations in gasoline/diesel production ratio.

Catalysts for hydrocracking

TK-971 catalyst

TK-971 is a zeolitic NiW-based hydrocracking catalyst with very high activity.

TK-951 catalyst

TK-951 is a high-activity hydrocracking catalyst, providing optimum diesel and naphtha yields, while minimizing overcracking.

TK-961 catalyst

TK-961 is a zeolitic NiW based hydrocracking catalyst with very high activity and a very high nitrogen tolerance.

Catalyst support

Our Catalyst Support is designed to support the combined weight of the catalyst, support material and oil. It can also withstand pressure drop over the catalyst bed during the entire catalyst ...

Inlet diffuser

Our Inlet Diffusers are designed to uniformly deliver gas and liquid to the distribution tray below, while keeping the liquid on the tray level.

Scale catcher

Our Scale Catching technology is a cost effective solution to delay pressure drop development and significantly increase unit utilization. Also reduces the amount of top grading material needed.

Outlet collector

Our Outlet Collector ensures even flow distribution in the bottom bed to maximize catalyst utilization and prevents bed migration to downstream piping and equipment.

Quench mixer

Our Quench Mixer ensures efficient mixing of catalyst bed effluents from both above and from the cold quench stream.

Redistribution tray

Our Redistribution Tray ensures uniform redistribution of the mixer effluents to the catalyst bed.

Distributor tray

Our Vapor Lift Distributor Tray (VLT) ensures uniform distribution of liquid and gas over the entire cross section area of the catalyst bed.

HPNA Trim™

Cost-effectively manage HPNAs in full conversion hydrocrackers by taking advantage of the heavy HPNA compounds' extremely high boiling points.

Revamping hydroprocessing units

There are many good business reasons for considering revamping a hydroprocessing unit. We provide support throughout all phases of the project.
