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

Although Helium exists in the atmosphere of Earth in small quantities‚ it is one of the most common element in the universe. It is a rare gas on earth. Helium was first discovered by Pierre Janssen in the spectrum of the sun during an eclipse in 1868. It was shortly identified as an element and was named by the chemist Sir Edward Frankland and the British astronomer Sir Joseph Norman Lockyer. Helium has an atomic number of 2 and an atomic weight of 4.002602. Helium is represented by the symbol

Exhaust Gas Recirculation 1. INTRODUCTION All internal combustion engines generate power by creating explosions using fuel and air. These explosions occur inside the engine’s cylinders and push the pistons down‚ which turns the crankshaft. Some of the power thus produced is used to prepare the cylinders for the next explosion by forcing the exhaust gases out of the cylinder‚ drawing in air (or fuel-air mixture in non-diesel engines)‚ and compressing the air or fuel-air mixture before the fuel is

Breakdown of the asset. While gas ovens can differ from model to model‚ they operate on similar principles. First lets explain how a typical gas oven operates and which problems may occur. A gas oven ignition system consists of three basic components; the oven controls‚ the igniter and the oven safety valve. In newer models the igniter will be a glow igniter‚ or in ovens that are a few years old‚ an electrical igniter. Old ovens may work with a pilot light igniter. In this breakdown we will

The reason for having a car is to get you from point A to point B and that’s it‚ no pit stops or a last minute party that you herd was suppose to be bad ass from a person you met 5 minutes ago. Gas is one of the main key for transportations but the way gas prices are going up we should just sell our cars on other things like food‚ people

So I guess it’s our family business and in whatever way we can help‚ we should help out. My grandfather works there like every day and some times he needs help with carrying things. I come with him to the store and once we get to our gas station‚ I arrange everything in the little storage room with my grandfather’s

contains aspirin (acetylsalicylic acid)‚ citric acid‚ and sodium bicarbonate. As the tablet dissolves in water‚ the bicarbonate ions in the tablet react with the hydrogen ions from the acids that are also contained in the tablet. The carbon dioxide gas produced by the reaction is what causes the bubbling that can be observed. HCO3- (aq) + H+ (aq) → H2O (l) + CO2 (g) In this investigation‚ you will design two experiments which will compare two different factors that may affect the rate of the

The Joule-Kelvin effect - the expansion of a real gas This famous experiment performed in 1852 was a follow-up to those of Gay-Lussac (1807) and Joule (1845) and demonstrated that there were indeed attractive forces acting between gas molecules. In theory‚ if attractive forces do exist then when a gas expands its temperature should drop. The potential energy of the gas molecules has been increased and therefore in an isolated system its kinetic energy‚ and thus its temperature‚ should fall.

for the rise and fall of prices over the years can be attributed to the supply and demand‚ while the future prices will still depend heavily on these two factors. There were a few main causes for the sharp rises in gas prices during 1999 to mid 2008 time period. The sharp rise in gas can mainly be contributed to the increase in the price of oil. The high prices of oil are attributed to the cases of supply and demand. The supply of oil has not increased enough to meet the new demand. Demand for oil
