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

Regulator Freeze Protection MICHAEL W. GILLIS P. ENG GROUP LEADER‚ MEASUREMENT AND PROCESS CONTROL ENGINEERING ATCO PIPELINES Introduction In the transportation of natural gas from wellhead to consumer‚ service conditions will be encountered which may cause the gas and equipment used to regulate and control pressure to experience freezing conditions. Ignoring these design considerations will result in reduced facility reliability and increased operating and maintenance costs. Regulator

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

Second Hand Smoking versus First Hand Smoking ! Smoking is the most deadly drug in the world. It kills 120‚000 people each year in the United Kingdom‚ and almost 90% of patients with lung cancer are attributable to smoking. However‚ smokers around the world are not the only ones in danger. Not only smokers‚ people around them are also in risk. Second hand smoking is as harmful as direct smoking. It is proven by research that exposure to other people’s smoke can increase the risk of cancer

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

Cons of Natural Gas Drilling Gas drilling has had the most impact on Pennsylvania ever since it was discovered. Whether or not it would have a direct impact on the environment is the question everyone has. Or “is it too good to be true?” obviously there are flaws in the idea of natural gas drilling and I am going to point these out whether or not you see the obvious issues on the matter is for you too judge for one’s self. My final question to you is how many people really going to make a huge
