Inert gas

However, the fuel covered three miles by ten miles of ocean and was allowed to dissipate naturally (Lawyer). This harmed local marine species, especially the krill population (Krill Facts). Since krill is at the bottom of the food chain, it is possible that the Odyssey’s explosion caused a greater impact on marine life, but no sources have data to prove this. The explosion of the Odyssey occurred in 1988. At that time the regulations regarding inert gas systems were as follows: An inert gas system was required on existing product carriers from 1 May 1983 and by 1 May 1985 for ships of 40-70,000 dwt and down to 20,000 dwt which were fitted with high capacity washing machines (IMO Protocol of 1978) Since the dead weight tonnage of the Odyssey was below 70,000 tons and was most likely not fitted with a high capacity washing machine, it is unlikely that the tanker utilized an inert gas system. The Odyssey was capable of carrying 132,157 tons of oil and on its last trip it completely filled its tanks. Without an inert gas system, the oil would be free to vaporize; leading to an increase in pressure. Furthermore, with turbulent conditions, the oil would become an electrostatic hazard. Static accumulation, due partially to insufficient grounding, can ignite a spark and cause an explosion when the fuel is between the LEL and UEL. Though no official report of the incident exists, it…

•Atomic Number -18 •Gas at 298 K •Density-0.0017837 grams per cubic centimeter •Third Noble gas •Chemical Symbol-Ar •It is also obtained from the air as a byproduct of the production of oxygen and nitrogen •It is the third most atmospheric gas •Argon is colorless and odorless •Argon is non reactive and has no effect on living organisms •Makes up 1% of the air around •Argon is found in the earth’s crust and in oceans •It comes from the greek word argos which means lazy…

Chemical effect The Chemical effect can affect and alter the combustion temperature due to chemical reactions taking place between the gases. One typical example is the consumption of heat of heat during endothermic reactions such as the dissociation of CO2 and H2O. Comparing all four combustion effects, it is noted that most of the NOx emissions reduction from CO2 comes from the dilution effect with an additional effect due to the chemical effect. The Thermal effect is considered to be…

Purpose The purpose of this experiment was to collect three different fractions of a mixture of hexane and toluene at differing temperatures. From there, the fractions would be measured via gas chromatography to discover the percent composition of hexane and toluene in each fraction with the ultimate goal of having one fraction with mostly hexane, one with mostly toluene, and one with an even mixture of the two. Along with this, there is also the goal of redistilling one of the fractions in…

Neon was discovered by Morris Travers and William Ramsay in 1898. Neon was discovered at the University College London in London, England. Neon is a gas so it is colorless, odorless, and tasteless. Neon has 10 protons, 10 neutrons, 10 electrons. [He] 2s2 2p6 is the electron configuration. Neon has 3 known Isotopes. The atomic mass for Neon is 20.1797. Neon glows when a high electrical voltage is passed through it. Neon does not form compounds with other substances and it is odorless. The risk…

Introduction: Photosynthesis is the process used by plants, algae and some bacteria, to use the energy from the sunlight to transform carbon dioxide and water into glucose and oxygen. The equation for photosynthesis is: carbon dioxide + water light energy glucose + oxygen. Chloroplasts are an organelle found in the leaves of green plants and are essential in photosynthesis as they are responsible for producing the glucose and storing the energy. Photosynthesis is vital for all life on…

Procedure: Before beginning each experiment, remove all clutter from the workstation and read the directions for the experiments thoroughly. Part 1: Warm slightly more than 300 mL of water to approximately 70 degrees Celsius. Measure out 150 mL of water into the coffee cup calorimeter. Take the temperature of this water in the coffee cup calorimeter once it has reached a steady temperature. Then, add an ice cube approximately the size of a large marshmallow. Stir the ice and water and measure…

steps that are critical to understanding the concept of equilibrium as a whole. First, an important concept to understand when describing any reaction is the idea of collision probability. When we examine gas molecules in a 1 cm3 container, there can be billions of collisions per second between neighboring molecules, and even then, maybe only one of these collisions result in a reaction. If any one collision occurs, the only way they will react to form a new molecule, in this case an HI…

Abstract This lab report focuses on the two experiments on pressure systems conducted, the Marcet boiler and Boyle’s law. The aim of this lab is to investigate in pressure-temperature relationship, Boyle’s law, as well as steam quality. The results of this experiment support both relationship, as well as successfully providing a value for steam quality. For the Marcet boiler experiment, it was found that the higher the system pressure, the higher the saturated temperature. For the Boyle’s law…

Ultrasonic interferometer Working principle An ultrasonic interferometer is a simple and direct device to determine the ultrasonic velocity in liquids with a high degree of accuracy. An ultrasonic interferometer is used to determine the accurate ultrasonic velocity in liquids. The principle used in the measurement of velocity is based on the accurate determination of the wavelength in the medium. The principle of ultrasonic interferometer for the measurement of velocity is determination of the…
