Utilisation of shale oil by the extraction and retorting of oil shale
Extraction of the bitumen fraction of oil shale was carried out using two different solvents, chloroform and toluene. Oil shale of 4.0 mm particle size from the El-Lajjun area in Jordan was used in this study. The solvents were recovered by distillation. The spent shale was retorted using a special retort and shale oil (Kerogen) was recovered. The quantity of the hydrocarbon was compared with ...

Ecological efficiency of the oil shale electricity sector of Estonia
Estonia is a typical postsocialist country with an inefficient energy sector, albeit uniquely based on oil shale mining and burning. This article comprehensively analyses the efficiency of the oil shale energy industry from mining to end use. The overall efficiency of oil shale energetics was estimated to be less than 20% (17% in 2002), with the losses attributed to wasting of co-produced thermal ...

Energotechnological oil shale utilisation by means of an SHCU - a low waste and environmentally sound technological process
This paper presents the calculated data on the emissions into the environment from the low-waste energotechnological solid heat carrier units (SHCUs) working with oil shales. A comparison of this technology with direct oil shale combustion at a power plant was carried out using the example of an Estonian power plant. The energotechnological plant (ETP) including two units SHCU-3000 with an oil ...

INCREASED OIL COMPETITION: SURVIVAL OF THE FITTEST
Is the U.S. shale oil industry in trouble? No, it is engaged in a high-stakes competition for market share. As oil flooded the market in 2014-15, prices dropped dramatically and producers began burning midnight oil to manage the downward economic pressures. While some overleveraged companies won’t survive the economic challenge, in true Darwinian fashion, the fittest will prevail. ...

New technologies for processing high sulphur oil shales and producing highly priced thiophenes
A technology for processing the light fraction of high sulphur oil shale pyrolysis tar is suggested. The technology allows some industrial hydrocarbon solvents, chemical reagents and sulphur-organic products (for example, thiophene, methyl- and dimethilthiophenes), which are used in organic synthesis, to be obtained and the production of different medical preparations etc.Keywords: Oil shale, ...

Estonia eager to teach world about oil shale
AUVERE, Estonia (AP) — Home to the creators of Skype and the first country to use online voting, Estonia relishes its image as a technological pioneer. But the tiny East European country's most far-reaching economic achievement could come from how it has learned to squeeze oil from a rock. About 200 feet (60 meters) below ground in northeastern Estonia, very close to the Russian border, ...

Experimental investigation of effects of oil shale composition on its calorific value and oil yield
This paper reports results of a detailed geochemical analysis carried out on representative oil shale samples obtained from the Attarat Um Ghudrandeposit, in Jordan. The conducted tests aimed to determine main features of the studied samples, such as oil yield, calorific value, organic and inorganic composition and moisture content. Based on obtained results of a large number of oil shale ...

A unified perspective on the phase behaviour of petroleum fluids
We present a coherent and unified group of general explanations for the various phase transitions, which may occur in the seven naturally occurring petroleum fluids with emphasis on their heavy organics. The seven petroleum fluids include, in the order of their fluidity, natural gas, near-critical gas-condensate, light crude, intermediate crude, heavy oil, tar sand and oil shale. At first the ...

Oil shales - a competitive fuel of thermal power generation with new technologies
We show that, in spite of the low heat of combustion of oil shales, use of them on the basis of a new thermal-processing technology that produces high-calorie products (shale tar and fuel gas) makes this type of fuel competitive for thermal power plants (TPPs) in comparison with high-calorie coals. When a certain amount of shale tar and all of the fuel gas are used in a combined cycle of a TPP, ...

The future of power generation in Estonia
Since 2004, Estonia has been a member of the European Union. With the Treaty of Accession the terms and conditions were set for the Estonian energy sector for compliance with the EU legal acts and the objectives of energy and environmental policies: 1) increase of the share of electricity produced from renewables; 2) opening of the electricity market; 3) bringing the oil shale based power ...

Dilemmas and solutions for a sustainable green transition
Mitigation of global warming and transitioning to a green and sustainable world are counteracted by a number of barriers and dilemmas. The paper analyses a number of these barriers and dilemmas in order to highlight efficient strategies and solutions for a sustainable development. Most governments in industrial countries do not pay enough attention to concepts as limits to growth in a finite ...

Optimizing Water Management in Hydraulic Fracturing for Shale Oil and Gas Production
Centralized treatment of wastewater is emerging as a viable solution for long-term efficiency in managing water sourcing and wastewater treatment in hydraulic fracturing. The number of hydraulic fracturing (fracking) shale oil and gas wells in the United States continues to increase. Within the Bakken Shale formation alone, in North Dakota and Montana, upwards of 15,000 hydraulic fracturing ...

A new species of global corporate risk: social issues, international firm expansion theory and crisis avoidance in the energy industry
International joint venture (IJV) agreements have long been regarded as the preferred method for risk mitigation for firms seeking to expand internationally. However, these agreements often fail to deliver on their promise of risk reduction, resulting in those firms managing conflicts and drawing the firm into a resource threatening crisis. The premise of this paper is that crisis management ...

The Future For Fracking
Summary -Fracking is an essential technology to meet growing global demand for oil and gas. -Fracking has become the "F" word, because it is very water-intensive, and has potential negative impacts on the environment. -The future of fracking will be constrained if adequate water is not available and if solutions for decontaminating wastewaters are not found. -Oil sands production faces the same ...

Microbiotests for the Evaluation of the Pollution from the Oil Shale Industry
Abstract : In this study a comparative chemical and toxicological analysis of 8 phenolic river water and wastewater samples originating from the Kohtla-Järve oil shale industry region (north-western part of Estonia) was made. The total phenolic content of the samples ranged from 0.01 to 195 mg/l. For 5 wastewaters the corresponding synthetic phenolic analogues were prepared. A battery of ...

Cement - The one and only in Estonia
Estonia is quite a small country and it also lacks good quality rock. However, in the northeast there are quality limestone deposits and also the only cement factory in the country. Today, Kunda Nordic Cement (KNC) follows proudly the tradition of cement production that started there in 1870. Now KNC belongs to the HeidelbergCement Group. Site, acquired recently by Kopar, has been a vital element ...
