Jun 06, 2021 Deeper refining is one of the ways companies can save resources by getting 1.5 times more petroleum products out of one tonne of oil. As the refining industry is among the most capital-, material-, and energy-intensive industries, it is clearly important to optimise refinery operations and get the most out of current assets, comment Ekaterina Kalinenko and Miro Cavkov - REFINING
Obviously, we need to spend some energy to bring the coal from the ground to the surface. So mining by itself has some kind of, lets say, about 95 efficient. Or that step is 95 efficient. In other words, if we have 100 units in the ground, and by the time this energy comes out to
This study defines a green mining system as a synergetic operation system composed of a mining subsystem and an environmental governance subsystem. Through conducting a case study of Chinas coal enterprises, this study identifies the mining subsystem as the first production stage and the environmental governance subsystem as the second production stage. To evaluate green mining efficiency
A reduction of 6.7 trillion Btu in annual energy use. A 4.3 reduction in overall energy use by this industry. An annual reduction of 470 million kg of energy-related carbon dioxide equivalent emissions from improved energy efficiency. The improvement is illustrated below.
deployment of energy efficient, environmentally sound technologies in U.S. industries. The primary focus of the IOF is the basic industries aluminum, chemicals, petroleum refining, glass, steel, forest products, metal casting, and mining. The State Industries of the Future SIOF program serves to extend the national IOF strategies to the
The analysis is aimed at identifying energy efficiency-related measures and developing energy abatement supply curves and CO 2 emissions reduction potential for the U.S. refining industry. A refinery model has been developed for this purpose that is a notional aggregation of the U.S. petroleum refining
Table 2 provides all process-specific energy efficiency opportunities grouped by process. Table 4 provides a matrix for the petroleum refining industry as organized in this report for each major process in the refinery in rows and the applicable categories of energy efficiency measures delineated in sections of this report in columns.
Recycling Catalysts Saves Energy and Protects the Environment The petroleum industry uses valuable metals in the production of fuels. These metals are incorporated in catalysts which are materials used to make the chemistry of oil refining more energy efficient and selective in
The now-defunct Mining Industry of the Future IOF program, administered by the Department of Energys DOEs Office of Energy Efficiency and Renewable Energy, supported engineering and technology development with a focus on improving the energy efficiency, resource utilization, and competitiveness of the mining industry.
Feb 12, 2021 A new tool counts bitcoin mining activity and cross-references users locations to make a heat map of energy use by all bitcoin miners. It turns out bitcoin mining uses more electricity than ...
Only the largest companies with access to cheap energy prices can find success mining BTC. But that doesnt make cryptocurrency mining entirely unprofitable. In fact, a new custom VIM3-ME based miner board designed for cost efficiency could optimize revenue streams for those interested in crypto mining.
May 22, 2021 Otherwise, Bidens clean energy agenda could fall short of its goals and leave the U.S. dependent on Chinas reckless mining industry. Michael Stumo is CEO of the Coalition for a ...
Jan 19, 2021 In the paper, Aste and Song detail that the Bitcoin network consumes a lot of energy, but the researchers still manage to estimate the lower bound for the global mining energy cost for a
May 31, 2021 The WEG IE4 super premium efficiency motor can add an additional 1 to 3 saving on energy consumption The cost and supply of reliable electricity has become one of the mining industrys biggest headaches, particularly in South Africa.

The mining industry consumed an estimated 551 trillion British thermal units Btu in 2002. 3 Major energy sources include fuel oil, electricity purchased and produced on-site, coal, and natural gas. The energy-intensive nature of mining is evident by the recovery ratio of the various materials being mined.

Oct 01, 2018 MINING.com asked three experts at Metso to discuss ways for mining companies to improve energy efficiency in comminution. The experts
Jun 01, 2020 However, secondary production, which involves the use of recycling scrap to make steel and aluminum, is much more energy efficient. The Environmental Protection Agency estimates that secondary steel production uses about 74 less energy than the production of steel from iron ore, while the U.S. Department of Energy reports that secondary aluminum production requires 90 less energy than primary production.
Further energy-efficiency opportunities can be achieved by implementing improvements in specific technologies, such as motors, pumps Box 22, fans Box 23, lighting Box 24 and air compressor systems. These systems consume a significant amount of energy in mining and mineral processing.
The energy-intensive nature of mining is evident by the recovery ratio of the various materials being mined. Coal, with an average recovery ratio of 82, requires the mining of 1.2 tons of material to recover 1 ton of coal. Industrial minerals have an average recovery ratio of 90, while metals have an average recovery ratio of 4.5.
In many cases, implementing energy efficiency measures is among the most cost-effective approaches that any refiner can take, improving productivity while reducing emissions. Therefore, careful analysis of the options and costs associated with efficiency measures
Oct 01, 2018 Energy-efficiency is one of the pillars of comminution circuit design, and ignoring this can be the difference between a profitable operation and a money loser. Mines rarely have control over the...
