  • Inquiry into coal seam gas

    Poorly planned or managed coal seam gas (CSG) exploration or extraction activities pose considerable risks to both groundwater and surface water systems. Key water quality issues, from my own perspective, are listed below. Specific issues may be of greater or lesser significance for particular projects, but all of these issues should be thoroughly and transparently assessed for all proposed (or ...

  • Why Are CHP Closing All Over The World?

    Burning of coal nowadays has become a big problem. The main reason for this is a rapid increase of mankind. So, China burns half of coal in the world. Since 2000 the share of coal in world energy production has increased from 25 to 30%, and the Chinese economy is responsible for 82% of this growth. In Beijing, it is customary to use ...

  • Ammonium, nitrate, and total nitrogen determination in fly ash

    Fly ash is a by-product of the combustion of pulverized coal and is composed of small particles. The composition of the fly ash may vary considerably, however, all fly ashes contain substantial amounts of silicon dioxide (SiO2), aluminum oxide (Al2O3) and calcium oxide (CaO). Nowadays, air pollution control standards require a separation of flue gas before being released to the atmosphere. Fly ...

  • Optimizing Wind and Solar Power in Africa

    Editor's Note: The following is a news release authored by Julie Chao and issued by Lawrence Berkeley National Laboratory on April 5, 2017 To meet skyrocketing demand for electricity, African countries may have to triple their energy output by 2030. While hydropower and fossil fuel power plants are favored approaches in some quarters, a new assessment by the Department of Energy’s Lawrence ...

  • Life Among The Heavy Metals

    Authors in scientific and applied works interpret the meaning of the concept "heavy metals" in different ways. Today, they include more than 40 chemical elements with an atomic mass of more than 50 atomic units. An important role in the determination of heavy metals is played by the following conditions: their high toxicity in relatively low concentrations, and the ability to bioaccumulation. ...

  • Comparison of Gas and Water Pycnometry of Coal Mine Wastes

    Coal mine washery wastes comprise two major components whose specific gravities differ markedly. Consequently, their specific gravity is much more variable than that of natural soils and is determined relatively frequently. The specific gravity of coal mine wastes is determined more rapidly and efficiently by gas pycnometry than by water pycnometry. However, the two methods give significantly ...

  • Beyond Coal; Optimization for Oil & Gas Units

    While coal reigns supreme among fossil-fuels for electricity production in North America, there are also substantial numbers of natural gas and oil-fired generating units. On one hand high fuel prices relative to coal can make it more difficult to cost-effectively operate these units; on the other, pressure to increase the capacity factors of these units will likely intensify in order to reduce ...

  • Polish gas from Polish coal: environmental benefits

    The development of coalbed methane gas from Polish coal offers a significant opportunity to reduce noxious pollutant emissions associated with coal combustion. A review of energy supply and consumption within Poland, and of available coalbed methane resources, indicates that use of coalbed methane could eliminate 40-60 million tonnes of sulfur dioxide and particulates from the atmosphere, save ...

  • Coal sorption characteristics and coal surface tension

    Underground coal mining in the Bulli Seam of Sydney Basin, Australia encounters the problems of coal and gas outburst as the coal contains high concentration of CO 2 , where certain parts of the seam have been found to be especially hard-to-drain. In order to better understand these problems, the influence of temperature and moisture on sorption capacity of bituminous coal was investigated at ...

  • Underground Coal Gasification: Converting Unmineable Coal To Energy

    Currently, about 1.5 billion people –almost a quarter of the world’s population— are without electric power. The International Energy Agency estimates that world energy demand (for all forms of energy, including transportation fuels) will increase by 36 percent by 2035 and fossil fuels, such as coal, will continue to play a critical role in meeting this demand. What is ...

    Coal is emerging as a major topic of conversation at the United Nations climate-change negotiations currently taking place in Warsaw – and rightly so. Indeed, it is a discussion that the world needs to have. The latest findings of the ...

  • Is `clean` coal possible?

    VANCOUVER, April 18, 2007 (GLOBE-Net) - Coal is the world’s most commonly used fuel to produce electrical energy, and will continue as such for some time. Yet it is one of the ’dirtiest’ of all fossil fuels. It is a major source of toxic air pollutants and the leading source of energy-related greenhouse gas emissions. Many believe ’clean coal’ technologies will improve the energy efficiency of ...

  • The alternative to coal in South Africa

    With a desperate need for dispatchable generation, South Africa should be readily embracing CSP as a low-carbon, sustainable, base load energy alternative. So why do its energy authorities remain unconvinced? This question has formed the subject of Part 2 of the CSP Today South Africa Guide. London, UK October 11 2011 Forget green energy: while most nations are concerned ...

  • An empirical study on the interaction between EUA futures, coal, natural gas and electricity

    This paper uses a Vector Error Correction Model (VECM), a method to estimate the adjustment speed of variables toward their long–run relationship in the short run, to investigate the dynamic relationship between the prices of EUA, coal, natural gas and electricity futures. It finds that there is a long–run equilibrium relationship between them. Short–run relationships between them are also ...

  • Recycling of coal seam gas-associated water using vacuum membrane distillation

    Coal seam gas-associated water (CSGAW), which is a by-product of coal seam gas (CSG) production typically contains significant amounts of salts and has potential environmental issues. In this study, we optimized a bench-scale vacuum membrane distillation (VMD) process with flat-sheet hydrophobic polytetrafluoroethylene (PTFE) membranes for the treatment of synthetic CSGAW (conductivity = 15 ...

  • Coal Fired Boiler two-stage flue gas desulfurization (FGD)

    A major pulp and paper mill located in New England, USA was faced with a control order to reduce SO2 and a schedule challenge to meet the order deadline and steam requirements. In addition, the customer was looking for ways to save reagent cost. Macrotek was selected to design and build two wet FGD systems for two 100,000 lbs/hr medium sulfur coal fired boilers. The design included a two-stage ...

  • Pressurised pulverised coal combustion ? a coal-based combined-cycle state of the cooperative project: cleaned flue gas matches specifications for use with gas turbines

    A high efficiency of 60% in a combined-cycle power plant technology with fuels like gas or light oil is estimated to be achievable. On the other hand existing conventional coal-fired power plants based on steam generation have an efficiency of about 40?45%. A huge potential of improvement in efficiency could be achieved by the implementation of a simple and cost-effective technology: PPCC, a ...
