Heavy Oil Upgrading

You are here: Home » Valve Applications

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

Datian valve 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.

Datian valve 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 Datian valve 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.
