Project Name: Sagar Manthan-Oil spill collector
Project Theme: Industry
Objective: An oil spill is the release of a liquid petroleum hydrocarbon into the environment, especially marine areas, due to human activity, and is a form of pollution. The term is usually applied to marine oil spills, where oil is released into the ocean or coastal waters.
Crude oil and refined fuel spills from tanker ship accidents have damaged natural ecosystems in Alaska, the Gulf of Mexico, the Galapagos Islands, France and many other places. The quantity of oil spilled during accidents has ranged from a few hundred tons to several hundred thousand tons
Oil spills at sea are generally much more damaging than those on land, since they can spread for hundreds of nautical miles in a thin oil slick which can cover beaches with a thin coating of oil. This can kill sea birds, mammals, shellfish and other organisms it coats.
Oil penetrates into the structure of the plumage of birds and the fur of mammals, reducing its insulating ability, and making them more vulnerable to temperature fluctuations and much less buoyant in the water. Animals that rely on scent to find their babies or mothers fade away due to the strong scent of the oil. This causes a baby to be rejected and abandoned, leaving the babies to starve and eventually die.
Oil can impair a bird’s ability to fly, preventing it from foraging or escaping from predators. As they preen, birds may ingest the oil coating their feathers, irritating the digestive tract, altering liver function, and causing kidney damage.
Sagar Manthan – Oil spill collector
It Is based on different principles of Science:
Chemical reaction
Metallic aluminium is very reactive with atmospheric oxygen, and a thin passivation layer of aluminium oxide (4 nm thick) forms on any exposed aluminium surface. , Aluminium oxide is responsible for the resistance of metallic aluminium to weathering. This layer protects the metal from further oxidation.
Law of floatation
Law of floatation states that density of objects less than that of the liquid will float and the objects with density more than that of the liquid will sink.
Viscosity
Of fluids is the property of a fluid (liquid or gas) by virtue of which an internal frictional force comes into play when the fluid is in motion and opposes the relatiave motion of it’s different layers. It is also called “fluid friction”.The opposing force is called the internal frictional force or viscous force and this property of fluid is called viscity. Thick liquids like oil, honey,diesel etc., are more viscous . Thin liquids like water, alcohol, ol, are less viscous
Causes of viscosity:
It is due to the inter molecular forces which are effective when the different layers of the fluid are moving with different velocities. Thick liquids flow very slowly where as thin liquids liquids flow fast.
Material Used:
For making our project, we have taken a circular Aluminum disc of diameter approx 26 cm, a motor to rotate the disc, Aluminum strip to extract the oil from the plate. We have used all recycled things to make our project like old used cardboard, wood from old broken benches and aluminum from scrap.
For the desired project:
The prototype displayed here uses a plate of 26 cm diameter which rotates 50 times per minute collecting 980 ml (approx.) of oil.
Working:
In this project we require an aluminum plate which is attached to the sides of the ship, near the base so that it is half immersed in water. When the ship moves the coupled plates move along with it. The plates react with the oxygen in air and in water and turns to aluminum oxide making its surface rough, thus increasing friction on the surface.
Oil being less dense floats on water. as viscosity of oil is far more as compared to water as oil is more viscous than water because of the strong intermolecular force of attraction in oil which causes more internal friction therefore more viscosity, it get attracted to the plate. As the plate rotates, a tunnel along with brushes at its sides collects the oil and pass it to the collector, where it can be reused.
The unique feature of the project is a little step for the protection of our BEAUTIFUL ENVIORNMENT.
Utility: Sagar Manthan is a A low cost, Chemical free, Pollution free, Eco friendly and a Measure to save marine bio diversity.
