ABSTRACT

Sorption using natural sorbents is an alternative method of oil spill treatment. This research proposed a polynomial equation that described the sorption behavior of Hibiscus cannabinus L. core in Bunker Oil C-seawater mixtures. This equation may be applied for oil concentrations of 0.001 to 0.003 mL oil/mL mixture and for a contact time of 15.00 to 120.00 min. The sorption behavior was characterized using specialized parameter define as Sorption Quantity (SQ) (g oil sorbed/g sorbent). The amount of oil sorbed by the Kenaf core was measured at different oil concentrations and contact times using mass balances. Design Experts, a computer software, was utilized in formulating the central composite design and in the statistical analysis which made use of the response surface method. Results show that the sorption behavior is best at high oil concentration and longer duration of exposure. Based on the sorption parameter, the most recommended time of contact is in the range of 65.00 to 95.00 min. The quadratic model was selected among other polynomial equations based on its R2 value of 0.9495 and p-value which is less than 0.0001 at a 0.05 confidence level.

INTRODUCTION

The availability of liquid petroleum in the form of crude oil and its refined products is a key driver in modern society, but its widespread use results in accidental and intentional releases resulting to oil spills. These oil spills have created large damages, casualties and losses on both marine and land resources. In addition, oil spills generally take about two to three years to clean

    BSC 1020: The Molecules Of Life

    Before it was capped, the well 5000 feet (1500 meters) below the sea surface leaked at least 200 million gallons of oil. (Some estimates are far larger.) One tactic BP used was to spray hundreds of thousands of gallons of DISPERSANTS into the gushing clouds of oil and onto surface of the ocean. Dispersants are a mixture of organic solvents and detergents which enable the oil to mix into the water. While this largely succeeded in getting the oil “out of sight, out of mind” by diluting it into a much larger volume of water below the surface, and helped increase of speed of chemical and bacterial breakdown of the oil somewhat, much of the oil is still there, just spread out more, and the dispersants themselves are also quite toxic. The full environmental damage of this spill and its “cleanup” will take years to…

    Explore the history of the sweetener (when it was developed, its composition). Sucrose, according to our text, is composed of one glucose (the most common sugar molecule) molecule and one fructose (the sweetest natural sugar) molecule. The bond is called glycosidic linkage. Because of this mixture, Sucrose is known to be sweeter than lactose or maltose (the other 2 out of the 3 most common disaccharides, which is a carbohydrate compound consisting of 2 or more molecules joined together). The history of sucrose dates back to thousands and thousands of years ago when the sugar cane was discovered in the South Pacific, rumored specifically to have been found in New Guinea. Its molecular formula is C12H22O11. (taken from Wikipedia)…

    In her article, Mary Grabar, author of “Boyz n the Book”. The article begins to explain the enrollment into a college by gender, as told by Department of Education, they recorded in 2005 the total fall enrollment made up to be 57 percent and knowing that gender discrepancies will increase in further dates. Grabar explains how women tend to excel in an English career and men typically in a mathematical, engineering career. To support, the article says that boys in high school fall lower in a reading test score than girls, but that’s justifying that the girls read every day rather than once a week. The article, “Boyz n the Book” emphasizes that males in schools tend to care more about what they want to read or what is more exciting to them and maybe what they would rather do instead of focus on an academic acceptance.…

    Current Ethical Issues on Oil Spill

    Today, with the continual and rapidly growing need of energy demand by big nations like United States and China continuing to furnish their domestic consumptions of oil have led to increased prices of gasoline whereby alternative forms of energy production are sought. With this in mind, offshore drilling can be a viable option for satiating the need of oil and also to boost the economy of the nation. In this report, I am going to discuss how the current Deepwater Horizon rig explosion has led to disastrous oil spill into the Gulf of Mexico causing environmental problems and also discuss how the oil spill if resolved and with safe and secure drilling techniques, the economic impact of offshore drilling can outweigh the environmental issues.…

    In the middle of the night of March 24, 1989, the giant oil tanker Exxon Valdez veered out of the shipping lanes in Alaska’s Prince William Sound and struck a reef. The side of the tanker was ripped open, and 11 million gallons of crude oil flowed out into Alaska’s clear blue waters. Because petroleum oil is insoluble (does not dissolve) in water and less dense, it quickly spread across the surface. The oil slick eventually covered 10,000 square miles, contaminating 1500 miles of shoreline, and causing substantial damage to wildlife, the fishing industry, and the marine environment.…

    The Legal Issues and Ethical Effects of the Deepwater Horizon Explosion and British Petroleum Oil Spill in the Gulf of Mexico 2010

    The Oil Pollution Act of 1990 was signed into law in August that year. It came about mostly because of the public response and concerns after the Exxon Valdez incident in which an oil tanker heading to port in Long Beach, CA ran aground in Prince Williams Sound, AK spilling up to an estimated 750,000 barrels of crude oil. Although ranking well down the list on the world’s largest oil spills for quantity dumped, the remote location of the spill made response and recovery extremely difficult. One of the key provisions of the OPA - §1002(a) Provides that the responsible party for a vessel or facility from which oil is discharged, or which poses a substantial threat of a discharge, is liable for: (1) certain specified damages resulting from the discharged oil; and (2) removal costs incurred in a…

    How Do Oil Spills Affect Marine Life

    Many people do not realize the impact of the oil spills that occur in the ocean. It is like putting water into a heated oil frying substance. It is quite catastrophic. With all the oil spills that have already occurred it is important to help clean ,and prevent oil spills from reoccuring. There is indeed a lot of reasons as to why we should clean and help prevent oil spills from happening but here are the three main reasons. First reason being oil spills cause immense harm to the marine habitats that intern affect the entire ecosystem disrupting its cycle. A second major reason being is all the things that the oil contains and where they go. The third reason we found that plays a major role involving…

    To What Extent Are More Recent Developments In Cold Environments Sustainable

    Oil spills can occur during transport of oil from the area. For example in 1989 there was a huge oil spill off the coast of Alaska when the exxon valdez oil tanker crashed. Over 40 million litres of oil spilled into the ocean and over 250 000 birds and fish were killed. Oil spills can occur if the pipelines leak between 1977 and 1994 there were on average 30 to 40 spills a year from the trans-alaska pipeline. Some of these were caused by intentional attacks and forest fires. Oil pipes have automatic shut off valves in order to minimise oil spills if the pipelines are damaged.…

    Bp Oil Spill

    The Oil Spill, due to the mismanaged oil drilling by British Petroleum (BP), in the Gulf of Mexico, has turned into one of the worst environmental disasters to happen to an ocean ecosystem of all time. Although many people only notice the effects on the hydrosphere, which include the oil going almost a mile deep under the sea, destroying the sediment and rock on the ocean floor, as well as disrupting coastal patterns, many have not realized the drastic effects on the biosphere because of this catastrophic event. The BP oil spill is viewed as the largest decimation of ocean wild life known to man, as well as also killing human lives in the process. Entire ecosystems have been affected in the process, harming animals like whales, dolphins, fish species, pelicans, seagulls, sea turtles, etc., several of which are already endangered. This destruction of wildlife has also lead to a slowdown in many fishing industries, further affecting human life, and causing severe poverty for those who rely on such business to survive. Even if some of the animals did survive, the trauma faced from this experience will lead to reproductive problems, or most likely, death. Even though life is returning back to the Gulf, the damage done can never be replaced, and the area will never be the same.…

    Oil Absorbed In Water Research

    The question that this experiment answered was “Does the type of material affect the amount of oil absorbed.” The hypothesis was “If a sponge is put in a container of oil, then it will absorb the most.” The independent variable was the type of material used, rag, paper towel, and sponge. The dependent variable was the amount of oil absorbed. Control variables were the same brand of the different materials used, the same batch of the mixture of paint and baby oil, and the same place. The experimental groups were the materials being placed in the oil. There were three control groups one was the sponge another was a paper towel and the last one was the rag. The procedures were that one at a time the materials were placed in the container. There are three groups, one group with the time in the oil at fifteen seconds, another group with a time limit of thirty seconds, and the last group with the time limit of sixty seconds.…

    The Gulf Oil Spill

    Imagine having to clean up 3.19 million barrels. There are many different variables that come into play, such as what time of oil it is, how the seawater mixes with the oil or how the currents, tides, winds and temperatures move the oil throughout the Gulf. The most basic process of cleaning up an oil spill is to control the spread of the oil using physical barriers. When oil mixes with water it tends to float to the surface and disperse across the surface. There are two methods to cleaning up an oil spill the first is physical. To clean up the oil on the surface works first surround the oil with floating booms to keep it from spreading even further. To pick up the surface oil they usually will use boats that skim the spilled water from the surface through the oil. Once most of the oil is removed workers use sorbents to mop up the trace amounts left behind. Sorbents act like a sponge and are able to soak up the oil. The second method of cleaning up an oil spill is dispersants. Dispersant is a chemical that breaks down oil into smaller particles that mix with water more easily. By doing this bacteria and evaporation can degrade these smaller particles more easily than if they were in bigger groups. Additionally, waves can wash away the smaller particles too. Dispersants are used mostly protect a certain area like a marsh or harbor. However dispersants can enter the food chain and harm animals. Dispersants…
