Engineering Workshop 1 Exhaust Gas Treatment Index of contents Introduction Waste gas with harmful traces of gas must be burned in an afterburner. To destroy the harmful traces the temperature after the burner must achieve 900°C. The preheater can`t resist a temperature of 700°C. Therefore quench water in a mixer will be used to protect the heat exchanger. The waste gas has the following properties: Waste gas composition: Mole fraction(= 0‚9890

Shale Gas(셰일 가스) Shale is one of the most common sedimentary rocks in the world and it is primarily composed of clay and fragments of other minerals such as quartz and calcite. Shale can be the source‚ reservoir and the seal for natural gas. Shale formations normally have low permeability (limited ability for gas or fluids to flow easily through the shale formation) and normally require stimulation techniques (such as fracturing) to economically produce shale gas. Shale gas is natural gas that

can cut thicknesses from 0.5mm to 2‚500mm‚ the equipment is low cost and can be used manually or mechanized There are several fuel gas and nozzle design options that can significantly enhance performance in terms of cut quality and cutting speed. Process fundamentals The cutting process is illustrated in Fig. 1. Basically‚ a mixture of oxygen and the fuel gas is used to preheat the metal to its ’ignition’ temperature which‚ for steel‚ is 700°C - 900°C (bright red heat) but well below its melting

• Natural gas is an odorless‚ colorless‚ flammable gas. It is non-toxic and lighter than air. • The gas chiefly consists of methane (CH4)‚ but also contains other hydrocarbons such as ethane‚ butane‚ propane and naphtha. Oil and gas deposits in the North Sea were formed millions of years ago through the decomposition and transformation of organic matter (plant and animal remains). In its primary form‚ natural gas can be used for residential heating and cooking‚ for industrial purposes

weapons became popular. Poison gas‚ such as mustard and chlorine became the number one thing to use. Gas was invented to cause fear to the soldiers the army was fighting. The gas could cause death quickly over a few days which was why poison gas was the most feared of all the soldiers. Poison gas could be used when the soldiers wanted to knock out a large amount of people without having to do much. Gun shots from a machine gun were more common but using the gas put the soldiers in more pain which

Professor Honeycutt English 1010 December 10‚ 2012 Gas Prices too high to pay Today gas prices have crept up to just over fifteen dollars a gallon. Due to rapidly depleted resources‚ the price of oil has gone to five hundred and thirty dollars; therefore the final price of gasoline had to increase. This has caused extreme violence to erupt all over the nation‚ especially at the gas stations themselves. People‚ in order just to fill up their gas tanks have had to sacrifice many things in their daily

Coal Seam Gas What is it? Coalbed methane‚ also more commonly known as coal seam gas (CSG) in Australia‚ is a type of natural gas removed from coal beds. It has been labelled as an unconventional natural gas along with tight gas and shale gas. They are labelled as "unconventional" as a result of their unusual reservoir types. It is removed from coal seams that are 300 - 1000 metres underground‚ and it is mainly composed of methane gas. It is typically extracted by drilling a steel-encased hole

efficient distribution and transmission network. High voltage gas insulated switchgear (GIS) is ideal for such applications. The range of application of SF₆ Gas Insulated Switchgear extends from voltage ratings of 72.5 kV up to 800 kV with breaking currents of up to 63 kA‚ and in special cases up to 80 kA. Both small transformer substations and large load- centre substations can be designed with GIS technology. The distinctive advantages of SF₆ Gas Insulated Switchgear are: compact‚ low weight‚ high reliability

BHOPAL GAS TRAGEDY By URJIT ZAVERI 14BLS119 On the night of December 2‚ 1984 forty one metric tons of methyl isocyanate also known as MIC was released from the Union Carbide factory in Bhopal. After one year of this incident almost 1800 people dies in this disaster and 320‚000 people had been affected by it. By 1991‚around 4000 people dies because of the gas in their body. Union carbide was a U.S company that started manufacturing pesticides in Bhopal‚ India. The valve malfunctioned on the 2nd December

The oil and gas industry is one of the world’s largest‚ complex‚ and expensive industry. The prices of oil and gas are probably the most closely plotted products in the global economy. In this industry there are three main segment of value chain: upstream‚ midstream‚ and downstream. It is evident that energy source play vital input to human activities‚ development‚ and growth of the economy. Hence‚ it is believed that after the industrial revolution‚ accessed clean‚ inexpensive and reliable energy
