An oil refinery or petroleum refinery is an industrial process plant where petroleum (crude oil) is transformed and refined into useful products such as gasoline (petrol), diesel fuel, asphalt base, fuel oils, heating oil, kerosene, liquefied petroleum gas and petroleum naphtha. Petrochemicals feedstock like ethylene and propylene can also be produced directly by cracking crude oil …

A coal preparation plant is a facility that washes coal of soil and rock, crushes it into graded sized chunks, stockpiles grades preparing it for transport to market, and more often than …
The Newcomen steam engine used the force of atmospheric pressure to do the work. This process begins with the engine pumping steam into a cylinder. The steam was then condensed by cold water, which created a vacuum on the inside of the cylinder. The resulting atmospheric pressure operated a piston, creating downward strokes.
Our coal processing solutions have proven themselves at the world's most demanding plants, freeing roughly 10 million tons of raw coal of impurities annually. Suitable for all advanced …
April 26, 1942: A coal-dust explosion at Benxihu Colliery in Japanese occupied China killed 1,549 making it the worst disaster in the history of coal mining superseding the 1,099 death toll of the Courrières mine disaster in 1906 and the second worst recorded energy accident, in terms of lives lost on a single day, after Banqiao dam in 1975. Despite the 1943 disaster on the hydroelectric ...

In particular, noise and habitat fragmentation can harm wildlife populations. ... This process involves crushing and washing the coal ...
A landfill site, also known as a tip, dump, rubbish dump, garbage dump, or dumping ground, is a site for the disposal of waste materials. Landfill is the oldest and most common form of waste disposal, although the systematic burial of the waste with daily, intermediate and final covers only began in the 1940s.In the past, refuse was simply left in piles or thrown into pits; in archeology …
Hematite (/ ˈ h iː m ə ˌ t aɪ t, ˈ h ɛ m ə-/), also spelled as haematite, is a common iron oxide compound with the formula, Fe 2 O 3 and is widely found in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 2 O 3.It has the same crystal structure as corundum (Al 2 O 3) and ilmenite (FeTiO 3).With this it forms …
Petroleum refining processes are the chemical engineering processes and other facilities used in petroleum refineries (also referred to as oil refineries) to transform crude oil into useful products such as liquefied petroleum gas (LPG), gasoline or petrol, kerosene, jet fuel, diesel oil and fuel oils.. Refineries are very large industrial complexes that involve many different processing …

The Environmental Protection Agency (EPA) is an independent executive agency of the United States federal government tasked with environmental protection matters. President Richard Nixon proposed the establishment of EPA on July 9, 1970; it began operation on December 2, 1970, after Nixon signed an executive order. The order establishing the EPA was ratified by …
The mining process is similar to coal mining, with both open pit and underground mines. It produces similar environmental impacts, with the added hazard that uranium mine tailings are radioactive. ... There are 16 processing plants in the US, although eight are inactive. Most uranium concentrate is made by leaching the uranium from the ore with ...
The Industrial Revolution was the transition to new manufacturing processes in Great Britain, continental Europe, and the United States, that occurred during the period from around 1760 to about 1820–1840. This transition included going from hand production methods to machines, new chemical manufacturing and iron production processes, the increasing use of steam power …
The world's electricity supply is dominated by fossil fuels. Coal is by far the biggest source, supplying 37% of electricity; gas is second and supplies 24%. Burning these fossil fuels for electricity and heat is the largest single source of global greenhouse gases, causing 30% of global emissions. 3 The chart here shows how the electricity prices from the long-standing …
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit.The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who …
Iron (/ ˈ aɪ ə n /) is a chemical element with symbol Fe (from Latin: ferrum) and atomic number 26.
