Liquid fuel production
We are one of the biggest producers of oil shale oil in the world
Oil from oil shale is essentially a synthetic oil used by heat producers, energy companies, manufacturers and sellers of marine and automotive fuels, road builders and farmers.
Eesti Energia has developed Enefit - a unique and efficient technology. Our goal is to expand cogeneration of liquid fuels, electricity and gas to ensure efficient oil shale refining.
Advantages of Enefit technology
Certifications and accreditations
Enefit technology is constantly evolving
Productivity, yields and accident-free operation have the greatest impact on the efficiency of production. In the last few years, the engineers of Eesti Energia have managed to significantly improve all three indicators, and this development work is to continue in the future.
Valuable oil from old car tyres
Old tires are a big disaster for nature, but for oil producers, it is energy-rich material, as one ton of tires contains about 4 times more oil than one ton of oil shale.
With the Enefit technology, up to 10% of oil shale can be replaced with old tyres and used to produce oil, semi-coke gas and electricity.
Our capacity is to produce liquid fuel from up to 260,000 tons of tires per year - thus we can utilize both Estonian and neighbouring countries' used tires. Tire chopping capability in Estonia does not yet allow the technology to be fully utilized.
How are tires made into oil?
To produce liquid fuels, oil shale is crushed, up to 10% crushed old tires are added.
Crushed oil shale and old tires are heated in retort at 500° C.
to release oil and gas vapors from the raw material.
