Outotec was awarded the lumpsum turnkey contract by DUBAL to design, supply, construct, test and commission a Liquid Pitch Unloading Storage and Handling Facility located at DUBAL's raw material terminal at Jebel Ali Port in February 2003. Only 14 months later the first delivery of 8,000 t liquid pitch was unloaded in one of the heated storage tanks.

DUBAL operated a solid pitch melting facility at its Green Annode Plant since 1979. To avoid the occupational hazards associated with the handling and melting of solid pitch, DUBAL now changed its operation and imports liquid pitch, carried by a dedicated ship from the Far East.
A liquid pitch storage terminal with two 10,000t heated storage tanks was constructed.

|
Transport of liquid pitch between this terminal and the smelter plant is carried out by special 35t road tanker trucks. |
Highlights of the Project
- Special articulated ship unloading arm to receive liquid pitch at approximately 200°C from a special ship at dock area.
- Heated piping system for transportation of liquid pitch to storage area.
- 2 x 10,000t heated tanks with nitrogen blanketing system to keep the liquid pitch at 200°C during storage.
- Hydraulically actuated loading arm with integrated fume return line for loading road tankers.
- 2 specialy designed road tankers for transportation of liquid pitch to anode plant area with quick connection coupling for easy handling.
- Circulation, loading and unloading pumps equipped with magnetic coupling for total sealing.
- Dock and anode plant terminals designed with special attention to safety and protection of the environment, such as elaborate fire protection and fighting system, fume return and treatment system, HTM system.
