Bituminous coal

the transports would have to deliver not only food, but coal for heating. The bags of coal would be bulky and take up most of a plane’s space. As the airlift’s operation increased it exceeded General Smith’s capability. As a result, the duties of running the airlift were given to the Military Air Transport Service and a new commander Major General William H. Tunner. General Tunner had previously operated an aerial supply line during World War II that crossed the Himalayas, from India to China.…

1. INTRODUCTION 1.1 What is biogas? Nowadays hydrocarbons are one of the biggest energy bases of our society, but it is not renewable energy, and once they are exhausted they cannot be replenished. (but as it is not a renewable energy once they are exhausted they cannot be replenished) Therefore, scientists from around the world have researched the use of other energy resources to continue moving the world, such as solar and nuclear energy, which are two main areas of research. However, there…

hydrogen nowadays, mainly for the production of ammonia and methanol. The other, being coal, can also be used to produce hydrogen but the initial investment is much greater and the efficiency is lower compared to when natural gas is used. Coal can be economically favourable when compared with natural gas for its lower feedstock cost [$1.26 per GJ LHV (lower heating value)], but due to high greenhouse gas emission from coal gasification makes it less favourable when compared with the lower carbon…

History Speech – Coal Seam Gas Introduction: (Intro to CSG/What are the two sides?) Good morning, I am here to advise you on the coal seam gas development and the issues surrounding it. Now what, what is Coal seam gas. Well coal seam gas also commonly known as CSG is a natural gas that is produced and trapped underground by water and ground pressure. The gas is harvested and extracted by drilling vertically into the ground, until a gas deposit is reached. The suppliers of CSG earns millions…

This informative article by Lutz Kilian discusses shale oil and its effect on oil prices in the United States. Shale oil is a term used by the oil industry for oil that is obtained from low-permeability rock, and it has caused a resurgence of oil production in the United States. This type of oil production was not available until quite recently, because of several technological advances in the industry. Currently, shale oil production, mostly from western states, accounts for a sizeable amount…

he Merriam-Webster Dictionary defines a crucible as, “a vessel of a very refractory material used for melting and calcining a substance that requires a high degree of heat.” Other interpretations of the word mean, “a severe test,” and “a place or situation in which concentrated forces interact to cause or influence change or development.” The Crucible by Arthur Miller and today’s society are very much like the inside of a crucible because they have social pressures, private pressures, and…

Introduction Acid rain is a rain that contains a high concentration of pollutants, chiefly sulfur dioxide and nitrogen oxide, released into the atmosphere by the burning of fossil fuels such as coal or oil .It can have harmful effects on plants, aquatic animals and infrastructure, when the sulfur dioxide and nitrogen oxide, react with the water . The chemicals in acid rain can cause paint to peel, corrosion of steel structures such as bridges, and weathering of stone buildings and statues.…

1. What are Seismic Imaging Technology and Chevron use of the technology? Seismic Imaging is a tool/technique to find the availability of crude oils and natural gas underground. It is also known as reflection Seismology as it is a process of inspection geophysics to evaluate the properties of Earth’s subsurface by using the principles of seismology from the reflected seismic waves. Sound waves are recorded by Seismologists using an ultrasensitive device called geophone as they echo under the…

By: Jorden and Claudia In the next couple paragraphs you will learn about copper sulfates names, its agricultural uses, its industrial uses, the many hazards, safety precautions, activity series, and displacement reaction. Also copper sulfate can be very useful but it is also very dangerous. Copper sulfate (CuSO4 and 5H2O) is also known as Blue Vitriol, Bluestone, Salzburg vitriol, Roman vitriol, Turkish stone, and Blue copperas. The mineral form of CuSO4 is chalcanthite. The white-gray…

Diesel engine The diesel engine (also known as a compression-ignition engine) is an internal combustion engine that uses the compression to initiate ignition and burn the fuel that has been injected into the combustion chamber. This contrasts with spark-ignition engines such as a petrol engine (gasoline engine) or gas engine (using a gaseous fuel as opposed to gasoline), which use a spark plug to ignite an air-fuel mixture. The diesel engines have the highest thermal efficiency in any internal…
