Viru Keemia Grupp is a private Estonian large-scale industrial enterprise. It focuses on oil shale mining, shale oil, combined heat and power production and production and marketing of fine chemical products.
Viru Keemia Grupp is located in Kohtla-Järve and continues the Estonian oil shale valorisation tradition that started in 1924. The company is based on private capital since 1997 when AS Kiviter was privatised. [1]
Estonia’s oil shale industry is a traditional Estonian industry, founded during the First Republic. Local oil shale industry provided heat and light to Estonian households starting from 1924, and supplied household gas to Leningrad and Tallinn as well as other Northern Estonian towns. The list of products made in Kohtla-Järve through decades is rich and varied – from shale oil to fine chemicals, epoxy resins to nitrogen fertilisers, hair dye components to bitumens.
VKG's two main areas of operations are shale oil extraction, and electricity and heat production and distribution.
The subsidiary producing shale oil is VKG Oil. The company utilizes two different processes: Kiviter and Galoter. [2] [3] [4] [5] The company also tested but rejected the Alberta Taciuk Process. [6] In total, VKG Oil processes 2 million tons of oil shale per year, producing 250,000 tons of shale oil.
The company operates several Kiviter retorts, the largest of them having a processing capacity of 40 tonnes per hour of oil shale feedstock. [7] [8] As of 2016, these retorts were out of operation due to low oil prices. [9] It also operates three Galoter-type retorts called Petroter. [5] Engineering of the retort was done by Atomenergoproject of Saint Petersburg; engineering of the condensation and distillation plant was done by Rintekno of Finland. [10] The first Petroter plant has a processing capacity of 1.1 million tonnes of oil shale per year, and it produces 100,000 tonnes of shale oil, 30 million cubic metres (1.1 billion cubic feet) of oil shale gas, and 150 GWh of steam per year. [5]
VKG's subsidiary VKG Energia, a power and heat generation company, was established in 2004 after VKG bought the Kohtla-Järve Power Plant and the Kohtla-Järve heat distribution system from Kohtla-Järve Soojus. [11] In 2005, it bought another power plant in Kohtla-Järve from Fortum Termest. [12] In 2006, VKG bought a 40.8% stake in Kohtla-Järve Soojus, an operator of the Ahtme Power Plant, and in 2010 it took a full control of the company, now VKG Soojus. [13] [14] All generations capacities were transferred to VKG Energia while VKG Soojus is responsible for heat distribution. [14] [15] All generations capacities were transferred to VKG Energia while VKG Soojus is responsible for heat distribution. [14] VKG Energia has installed electrical capacity of 80 MW and heat capacity of 700 MW. [16]
In July 2006, VKG acquired Narva Elektrivõrk, the second-largest power distribution company in Estonia, [17] and renamed it VKG Elektrivõrgud. [18] [19] [20]
In April 2011, VKG acquired assets of a bankrupt company Silbet Plokk that manufactured cinder blocks for construction from oil shale burning residue. [1] [21] [22] The company was renamed VKG Plokk. [22] The coalition-agreement of Jüri Ratas' second cabinet formed in 2019 between the Centre Party, EKRE and Pro Patria, expresses support to the development of the local oil industry. [23] Therefore, VKG and Eesti Energia decided to initiate a cost-benefit study aimed at establishing an oil pre-refining plant in Ida-Viru County. The plant would require a 650 million euro investment. [24]
Main subsidiaries of VKG are:
Kohtla-Järve is a city and municipality in northeastern Estonia, founded in 1924 and incorporated as a town in 1946. The city is highly industrial, and is both a processor of oil shales and is a large producer of various petrochemical products. During the 1944–1991 Soviet occupation, large numbers of immigrant workers from Russia and other parts of the former USSR were brought in to populate the rapidly growing city. The population in the Kohtla-Järve area which had been, as of 1934 census, over 90% ethnic Estonian, became overwhelmingly non-Estonian in the second half of the 20th century. According to more recent data 21% of the city's population are ethnic Estonians; most of the rest are Russians. Kohtla-Järve is the fifth-largest city in Estonia in terms of population.
Eesti Energia AS is a public limited energy company in Estonia with its headquarters in Tallinn. It is the world's biggest oil shale to energy company. The company was founded in 1939. As of 2014, it operates in Estonia, Latvia, Lithuania, Finland, Jordan and Utah, United States. In Estonia, the company operates under the name Eesti Energia, while using the brand name Enefit for international operations. The main raw material for energy production – oil shale – is extracted from mines located in Eastern-Estonia and owned by the company. The group of Eesti Energia has three main operation areas: electricity generation, shale oil production, and sale and distribution of electricity. Its shares are owned by the Government of Estonia.
Enefit Kaevandused was a mining company located in Jõhvi, Estonia. It was a subsidiary of Eesti Energia, an Estonian state-owned energy company. The core activity of Enefit Kaevandused was oil-shale mining. The produced oil shale was mainly used for shale oil production and to fuel oil shale-fired power stations in the north–east of Estonia. As of 2009, the company had 3,150 employees. The last chief executive officer was Andres Vainola. The company produced more than 17 million tons of oil shale in 2013.
The Narva Power Plants are a power generation complex in and near Narva in Estonia, near the border with Leningrad Oblast, Russia. The complex consists of the world's two largest oil shale-fired thermal power plants, Eesti Power Plant and Balti Power Plant. In 2007, Narva Power Plants generated about 95% of total power production in Estonia. The complex is owned and operated by AS Narva Elektrijaamad, a subsidiary of Eesti Energia.
The oil shale industry is an industry of mining and processing of oil shale—a fine-grained sedimentary rock, containing significant amounts of kerogen, from which liquid hydrocarbons can be manufactured. The industry has developed in Brazil, China, Estonia and to some extent in Germany and Russia. Several other countries are currently conducting research on their oil shale reserves and production methods to improve efficiency and recovery. Estonia accounted for about 70% of the world's oil shale production in a study published in 2005.
Environmental impact of the oil shale industry includes the consideration of issues such as land use, waste management, and water and air pollution caused by the extraction and processing of oil shale. Surface mining of oil shale deposits causes the usual environmental impacts of open-pit mining. In addition, the combustion and thermal processing generate waste material, which must be disposed of, and harmful atmospheric emissions, including carbon dioxide, a major greenhouse gas. Experimental in-situ conversion processes and carbon capture and storage technologies may reduce some of these concerns in future, but may raise others, such as the pollution of groundwater.
The history of the oil shale industry started in ancient times. The modern industrial use of oil shale for oil extraction dates to the mid-19th century and started growing just before World War I because of the mass production of automobiles and trucks and the supposed shortage of gasoline for transportation needs. Between the World Wars oil shale projects were begun in several countries.
Oil shale gas is a synthetic non-condensable gas mixture (syngas) produced by oil shale thermal processing (pyrolysis). Although often referred to as shale gas, it differs from the natural gas produced from shale, which is also known as shale gas.
There are two kinds of oil shale in Estonia, both of which are sedimentary rocks laid down during the Ordovician geologic period. Graptolitic argillite is the larger oil shale resource, but, because its organic matter content is relatively low, it is not used industrially. The other is kukersite, which has been mined for more than a hundred years. Kukersite deposits in Estonia account for 1% of global oil shale deposits.
Narva Oil Plant is a commercial scale shale oil retorting facility located in Auvere near Narva, Estonia. The plant produces shale oil from oil shale by using Galoter/Eneffit technology. The facility belongs to Enefit Energiatootmine, a subsidiary of Eesti Energia.
The Kiviter process is an above ground retorting technology for shale oil extraction.
The Galoter process is a shale oil extraction technology for the production of shale oil, a type of synthetic crude oil. In this process, the oil shale is decomposed into shale oil, oil shale gas, and spent residue. Decomposition is caused by mixing raw oil shale with hot oil shale ash generated by the combustion of carbonaceous residue (semi-coke) in the spent residue. The process was developed in the 1950s, and it is used commercially for shale oil production in Estonia. There are projects for further development of this technology and expansion of its usage, e.g., in Jordan and the USA.
The Alberta Taciuk process is an above-ground dry thermal retorting technology for extracting oil from oil sands, oil shale and other organics-bearing materials, including oil contaminated soils, sludges and wastes. The technology is named after its inventor William Taciuk and the Alberta Oil Sands Technology and Research Authority.
Northern Estonia is a geographical region of Estonia, consisting of the three northernmost counties - Harju County, Ida-Viru County and Lääne-Viru County. The largest towns of Northern Estonia are Tallinn, Narva, Kohtla-Järve and Rakvere. Northern Estonia is the most populous area in Estonia, with 60.3% of the population living there.
