TECHNIP is co-operating closely with METSO Minerals, Inc., USA (KvStechnology) for about 25 years on the implementation of coke calcining plants and has since 1993 an exclusive agreement for many countries in the world.

METSO Minerals, Inc. is the world’s leading supplier of coke calcining technology, having furnished 50 plants representing approximately 70% of the world’s coke calcining capacity.

TECHNIP designed and executed 6 out of 15 Calciner Projects worldwide. This includes the latest and biggest green-field Calciner Project, the ALBA Petroleum Coke Calciner Plant in Bahrain with a production capacity of 450,000 ton per year.

Introduction

3

Petroleum Coke Calcining is a process whereby green or raw petroleum coke is thermally upgraded to

- remove associated moisture and volatile combustion matter- improve critical physical properties like

electrical conductivityreal densityoxidation characteristics

The feedstock "Green Coke" is a by-product of the coker process in oil refineries.

Description of Technology

4

Calcined petroleum coke is an important industrial commodity linking the oil refining and metallurgical / chemical industries.

Calcined petroleum coke is required in:

the aluminium industry to manufacture anodes for the aluminium potlines

the steel industry

to manufacture carbon and graphite electrodesas carbon raiser

the chemical industry as a feedstock for the production of Titanium Dioxide by the modern chloride process route

PETROLEUM COKE CALCINING may be achieved in a :Rotary Kiln or

Rotary Hearth or

Shaft Kiln

The trend nowadays is to build rotary kiln types only due to :

flexibility in accepting a wide range of green coke feed qualities

production capacity

consistent calcining conditions due to the rotation of the Kiln

low percentage of dust content in the product

higher calcined coke grain stability

good operation experience

low maintenance and operating cost process
