Abstract
This paper begins by illustrating the process most commonly used to remove hydrogen sulfide from natural gas. The paper then goes on to describe an alternative method used for the removal of hydrogen sulfide and describes the benefits of this method, as well as some of the problems associated with it. Additionally, the paper points out that the water content of natural gas is an important engineering consideration concerning the sweetening process and presents an overview of the properties of pure acid gases and water and hydrogen sulfide. The paper then goes on to outline and explain additional processes and engineering considerations concerning the removal of hydrogen sulfide and includes some cost estimates and comparisons of the processes.

From the Paper
"Sour natural gas contains hydrogen sulfide (H2S), which has to be removed to meet specifications for sales gas. Sour natural gas also contains carbon dioxide (CO2). The removal of CO2 and H2S, usually called acid gases, from sour natural gas is generally accomplished by means of a regenerative solvent. There are several amine solvents used for this purpose. Upon regeneration of the solvent, the acid gases are liberated, and are usually sent to a modified Claus plant, where the H2S is converted to elemental sulfur (Canjar & Manning 1967). The acid gas stream to the modified Claus plant consists of H2S, CO2, water vapor and minor amounts of hydrocarbon gas."

Abstract
This paper explains each of the 5 major gas laws and cites specific examples of the application of each. This essay argues that these gas laws are responsible for advancements in industry and medical devices. Furthermore, this essay describes how one gas law, Boyle's Law, explains how the human body takes in oxygen and expels carbon dioxide through the lungs.

From the Paper
"The development of the Chemical Gas Laws throughout history has provided scientist and industry with some unique insights. These developments have made advancements in medicine i.e. membrane technology and industry (mineral development) more effective and efficient. The purpose of this essay will be to examine the five major gas laws: (1) Graham's Law; (2) Charles' Law; (3) Boyle's Law; (4) The Combined Gas Law and (5) Dalton's law of partial pressure. Each of these laws will be explained and will be punctuated with relevant, real-world applications."

Abstract
In this article, the writer provides an informative description of mustard gas as a weapon of war. The paper looks at when and where it was used during the First World War and then discusses its effectiveness. The writer then goes on to discuss, in a similar manner, the numerous occasions that mustard gas has been used post-World War One.

Outline:
Mustard Gas in the First World War
Wilfred Owen, Dulce et Decorum est (1917)
Uses after the First World War

From the Paper
""The First World War saw Mustard Gas seen in the largest scale and in the most famous example as a weapon of war. Although during this conflict more lethal gases had been used as weapons previous to the use of Mustard Gas, (such as chlorine) these gases did not have the dermatological affect that Mustard gas has. It was for this reason that gas masks issued to most soldiers on the Western Front during World War One were of little use in countering the effects of the gas and hence it was also for this reason that Mustard Gas was such an effective weapon."

Abstract
The paper argues that the natural gas vehicle is actually better than the electric automobile - chiefly because it remains somewhat more convenient to re-fuel, and because the long-term durability of the EV remains in doubt. The paper notes that both types of vehicles have their advantages, and the paper outlines the strengths of each. The paper concludes that while this writer gives a slight advantage to a natural gas-propelled vehicle, purchasing either type will turn out to be a judicious choice.

From the Paper
"The following paper will argue that the natural gas vehicle is actually better than the electric automobile - chiefly because it remains somewhat more convenient to re-fuel, and because the long-term durability of the EV remains in doubt. Be that as it may, both types of vehicles have their advantages, and the next several pages will outline the strengths of each. In the final analysis, while this writer gives a slight advantage to a natural gas-propelled vehicle, purchasing either type will turn out to be a judicious choice. To begin with, it is simply inaccurate to suggest that gas automobiles are..."

Abstract
This paper summarizes the Bhopal toxic gas disaster of 1984 when the explosion in a tank of MIC caused a poisonous cloud of gas to be released, killing roughly 3,000 people and injuring 200,000. Union Carbide was a part owner of the plant and took full responsibility for the disaster, which was caused by employee sabotage.

From the Paper
"In December 1984, there was a disastrous explosion at the Union Carbide pesticide plant in Bhopal, India. Although exact figures are still disputed, roughly 3,000 people died and 200,000 people were injured as a cloud of toxic methyl isocyanate (MIC), hydrogen cyanide, monomethyl amine and carbon monoxide was released into the atmosphere surrounding the plant. Union Carbide immediately took full responsibility for the disaster and CEO Warren Anderson flew to Bhopal two days later to take charge of the investigation and make compensation to the victims. However on..."

Abstract
The following paper discusses the 1984 Bhopal Gas tragedy, its aftermath, and how the four "I's" - issues, interests, institutions, and information - manifest themselves in any discussion of this calamity. The writer argues that the tragedy could have been avoided, and it is now up to NGOs, concerned government officials, and to the international community to see to it the chemical industry does not "get away with murder" yet again.

"The following paper will discuss the 1984 Bhopal Gas tragedy, its aftermath, and how the four "I's" - issues, interests, institutions, and information - manifest themselves in any discussion of this calamity. In the final view of this writer, the tragedy could have been avoided, and it is now up to NGOs, concerned government officials, and to the international community to see to it the chemical industry does not "get away with murder" yet again. On the night of December 2^nd and 3^rd, 1984, a union carbide plant in Bhopal, India, began leaking tons of the deadly gas, methyl isocyantate..."

Abstract
This paper reviews David Goldstein's book "Out of Gas" which gives a detail explanation of the history of fossil fuels and their use. It further examines the impending exhaustion of this resourse, and the technical problems to be overcome to solve this problem. The book does not offer any tangible solutions to the problem of oil running out in the latter half of this century, just a dire warning.

From the Paper
"David Goldstein in his book 'Out of Gas' makes the dire prediction that civilization as we know it will cease to exist by the latter half of the twenty-first century unless society as a whole learns to live without fossil fuels. The choice will be made not by the political leaders or a new philosophy of life, but by the mathematical predictions of a geophysicist by the name of Marion King Hubbert. Mr. Goldstein then proceeds to eloquently and efficiently compress the history of the planet Earth and the creation of the oil reserves, global warming, the scientific theories that gave rise to the industrial revolution, and the detailed..."

Abstract
This paper presents an analysis of the consequences of shutting down a gas pipeline in Arizona for a couple of weeks. It further considers how the shut down affected prices and how the price changes affected supply and demand and their associated curves.

From the Paper
"When prices change, supply and demand change as well. Sometimes it is only the quantity supplied and quantity demanded that change. This results in movement along the supply and demand curves. Depending on the source of the price change however there may be a shift in supply or demand or both. This results in a shifting of the curves. This analysis considers how a price increase in gasoline resulting from shutting down a pipeline in Arizona for a few weeks might affect the supply..."
