A byproduct of the oil refining process, petroleum coke, also known as pet coke, is a carbonaceous solid delivered from oil refinery coker units or other cracking processes.
The coker unit was jointly developed by the RIPI and the Iranian Mines & Mining Industries Development & Renovation (IMIDRO).
In 2012, IMIDRO was awarded a project to design and manufacture the unit under a research contract with Research Institute of Petroleum Industry (RIPI). The 200,000-ton unit took IMIDRO some 38 months to complete.
The unit is fed by 27,000 barrels/day of refined crude oil residues.
Coking procedure is a normally-used technique for quality promotion in the world's most advanced refineries.
Different distillates and pet coke are products of the coking process. Pet coke is mainly used in steel and aluminum industries.
Only in its aluminum industry, Iran needs 200,000 tons/year of the product which it had to import from foreign suppliers.
Iran produces 475,000 tons/year of aluminum which is expected to hit 1.5mt/y by 2025.
Pet coke is a strategic petroleum byproduct and the aluminum industry is highly dependent on it.
Production of highly valued petroleum byproducts from low-value oil residues is one of RIPI's founding missions.
Coking processes that can be employed for making pet coke include contact coking, fluid coking, flexicoking and delayed coking. Coke has traditionally been delivered from coal.
