Heavy Oil Upgrading

Over the last years SchuF has developed many different valve designs for heavy oil upgrading applications.


SchuF is a world leader for valves for Bergius Pier type of upgrading. In this process, hydrogen is reacted with feedstock such as coal, residue and/or heavy oils under high pressure and temperature in the presence of a catalyst. The subsequent stages of pressure let down and separation from about 200 bar to vacuum at up to 500°C  in several stages are very severe for the valves involved.

SchuF valves have been used successfully in the KAB VCC plant (first modern commercial scale plant) and the Shenhua DCL plant.
Other clients include PDVSA/Intevep, KBR and Saipem ENI.

Over the last years SchuF has developed many different valve designs for heavy oil upgrading applications as e.g.:


2-in-1 Control Valve

The 2-in-1 Control Valve is a new development to minimize erosion and fluctuation in pressure and levels. It combines two trims in a single valve.

High Pressure Angle Control Valve

High Pressure Angle Valves are used as double block and bleed systems where ball valves have gotten stuck.

Single Stage Letdown Valve

The Single Stage Letdown Valve (shown below) enables level control of HHPS, MHPS and atmospheric distillation. It is able to handle δP of up to 180bar at 500°C with severe flashing and high solids content

Diverter Valve with Flush Valves

The diverter valve for heavy oil upgrading (shown below) distribute residue to several parallel redundant control valves and pumps.
Diverter valves are designed to divert or combine flow without any dead space inside the valve.
