Estonia shale oil industry
Enefit has long and unique experience in producing liquid fuels from oil shale. Continuous development has allowed us to expand production volumes and the stability of our Enefit140 machinery. It is important for the environment that, while we have increased production volumes, we have equally managed to lower environmental emissions. In Estonia we have implemented several initiatives to significantly reduce the environmental impact of our operations.
Enefit has a wealth of experience in mine remediation.
We often say that our business starts and ends with mining. A key step in the mining process is the restoration and rehabilitation of mining areas.
Ash removal in Estonia uses a hydro pulp transportation system, in which water is constantly recycled back into the system by means of transportation pipes, canals and settling ponds.
For all projects outside of Estonia, Enefit plans to use dry ash removal systems with minimal water use for dust prevention.
The water released back into environment is cleaned thoroughly. There is an operating commercial fish farm, which operates using cleaned water.
The new Enefit280, which was completed in 2012, is twice as powerful in comparison to the Enefit140 and it uses the new circulating fluidized bed technology. This new technology will allow us to increase liquid fuel production volumes significantly without damaging the local air quality. Read more »
Oil Shale Ash as a Raw Material. The chemical composition of oil shale ash gives it great potential as a raw material in many ways. The fly ash is already being used in cement production. It is mostly done in Kunda Nordic Tsement's factories, where a special portland cement is produced from our fly ash. Fly ash eliminates the very intensive CO2 processing procedure, instead involving only portland cement's components, thus significantly decreasing the CO2 footprint resulting from oil production.
