Oil Pollution Controls

Oil pollution control is a method carried out to prevent marine life from getting destroyed due to oil spills. There are various reasons why oil spill occurs. An oil tanker may accidentally have a damaged pipeline releasing crude oil in the sea. Oil dumped on land may also run off into water. Even though it can also happen on land, ocean oil spill are considered more catastrophic.

 

Natural seepage is another cause of oil spills. Reserves beneath the ocean surface can release oil when there has been a shift on tectonic plates. This activity may be triggered causing massive release by human activity such as offshore drilling especially when a failure in the system or blowout occurred.

 

Land based oil spill could happen by simply running an automobiles. Vehicles operate by burning petroleum-bases fuel injected on their engine. While they are running, fuel substances are slowly released landing on the ground. When it rains, the oil will flow finding its way to the nearest stream until it reaches the ocean. This type of oil spill is not considered a huge threat since the rate of the release of oil is slow and only a few, the oil will accumulate over time causing serious not only to land but also to the coastal area.

 

Unlike oil spills from automobiles, dumping of used oil is a great source of oil pollution. This practice involves releasing of huge amount of oil at once which could quickly pollute the ocean and kill the marine creatures. Incidents in oil fields can also cause massive release of oil. Oil extracted underneath the land or the ocean’s surface flows through pipeline to reach the surface. The success of transporting of oil depends on the condition of pipelines. There are many reasons why pipelines get damage. It could be caused by excessive pressure from high volume of oil releasing, natural disasters such as earthquakes and hurricane, structural failure or wearing out from frequent usage.

 

Increasing environmental concerns paved the way to various oil pollution controls. There are tools built to contain and clean-up oil spills. Booms serve as a barrier to prevent the oil from spreading. This method allows the oil to be collected in one place which makes their removal easier. Booms do not only contain oil from the surface but also those flowing underneath. After the oil is collected, the next step is to remove them. Removing of oil can be done in various ways. One is with the use of skimmers. Skimmers are mechanical devices which pumps oil into a container. Another type of oil pollution control is with the use of sorbent. It is a material that absorbs oil from the water. The three types of sorbents are natural organic, natural inorganic, and synthetic sorbents.

 

There are chemicals in the form of dispersing agents and gelling agents that alter the appearance of oil. Dispersing agent turns the oil into small droplets that further disintegrates with the help of currents and waves. Gelling agent, on the other hand, is an oil pollution control that transforms the oil into a rubbery substance when poured to oil spills. The substance is them removed with the use of skimmer or net.
