Natural gas transmission pipeline network system. Introduction One of the most widely used source of energy in world is natural gas (NG) and is due to its environment friendly characteristics. The distance between the resources and the place where it is needed is usually far apart. It is more economical to transport natural gas by pipeline compared to Liquefied Natural Gas (LNG) for short distance. In transmission pipeline network system (TPNS), gas flow through various devices such as regulators

where, first level is heat exchange between LNG and intermediate fluid like propane and the second level is heat exchange between intermediate fluid and sea-water. The surface areas of the heat exchangers are optimized to have maximum heat exchange. The major advantage of STV’s is, they prevent freezing (unlike ORV’s) and reduce fouling risks. But of course, they are costly because of use of intermediate fluid like propane.  Ambient air vaporizers The emissions because of SCV’s and unknowns associated

The aim of this experiment was to test the heat of combustion over a period of time, and the energy required to combust alcohols with different carbon chain levels. It was hypothesised that the higher the carbon chain of the alcohol present, the faster the heat of combustion will occur. Meaning more energy will be released for a higher carbon chain. After calculating the results from the experiment it was found that the hypothesis was partially supported. The reasoning for this is as the alcohol

What Is Flakka? Flakka is a synthetic drug that is very similar to cocaine. It is sometimes called gravel because it resembles aquarium gravel. Flakka has a chemical that is very similar to MDPV, which is an ingredient that is found in bath salts. Flakka can be injected, snorted or smoked. It causes users to experience an intense euphoric feeling. Users experience an increase in energy and heightened awareness after using Flakka. The high that a person experiences after using Flakka can last for

off and the power poles have been snapped like twigs, looking like Tokyo after Godzilla's drunken Saturday night outing. That can mean acquiring a gas burning stove, such as a one-burner butane stove. The problem here is that you use the butane (or propane) tanks up too quick and also the dangers inherent in storage of gas. Another possibility is the family hibachi, Dutch oven, or backyard barbecue, whether a little $5 job from WalMart or the brick grill-and-pottery-kiln in the yard. Stock up on appropriate

What is freedom to you? To me, freedom is the ability to go anywhere and do anything you want without having to worry about any restrictions holding you back. While no one will ever have a sense of true freedom, I found freedom by living in a van. I decided to live in a van for many reasons but the one that appealed to me the most was being able to go anywhere for any amount of time whenever I felt like it. This is the story of how I quit my 9-5 job and became a traveling nomad residing in my van

My family and I go on a camping trip to Allegheny State Park every year. We have many funny memories from the trips. Many of the stories revolve around the bears that live in the mountains in Allegheny State Park. The funniest had to happen three years ago. The camping trip took place in the month of August, just like every year. The trip included my parents, siblings, and my uncle, aunt and cousins. Every year we rent two cabins right next to each other. This year the bears were coming up to the

using these massive amounts of water every time a well is fracked, all the used water, when finished, is causing significant amounts of pollution. In response to the current criticism, engineers have developed waterless fracking operations, where propane gel, butane, and other liquid and gas alternatives are used to break the shale that is deep beneath the Earth’s surface. Even though this new water-free system does not use the massive amounts of water like its hydraulic counterpart, there are still

year long in either rain or shine. Propane is naturally occurring and it is composed of eight hydrogen atoms and three carbon atoms. It is created by the decomposition and reaction of organic matter over long periods of time, along with a variety of other hydrocarbons like gasoline, crude oil and butane. Propane is a liquefied petroleum gas. It is more compact in a liquid state than in a gas state, which allows for easy transport and storage. The burning of propane is a Combustion reaction. It’s an
