The great accidents of oil spills in history and the consequences of them, in English, thank you tha

The accident occurred on October 3, local time in the United States, and about more than 3,000 barrels** were leaked off the southern coast of Asia in California, USA. According to official US reports, the spill formed an oil slick with an area of nearly square kilometers. So what caused this major leak in the United States?

The official reason has not yet been announced, but we can consider it from the following aspects.

First, it is likely to be caused by aging and improper operation of the pipeline. Leakage is a very serious matter, and the security standards of various countries are also different. As an old developed country, the United States has been the largest storage equipment in California Asia for many years.

It is very likely that some pipelines are aging, and the on-site maintenance personnel failed to find the problem in time, which eventually led to the ** leakage incident.

Second, human factors lead to leakage. In fact, many things may be caused by human factors, although the cause of the leak has not yet been announced, but the cause of human interference cannot be ruled out. For example, improper operation by the operator, drunken operation, etc., may be important reasons.

Third, there may be weather reasons. Weather is a very important factor. Previously, the weather in California has been relatively stable, but once there is extremely bad weather, it may lead to oil pipelines** and so on.

Although there is no specific reason for the leak of California Asia**, it is most likely caused by these factors, or a combination of several factors. This leak is still quite serious, and it can be regarded as the most serious leak in the history of the United States.

For example, Orange County warned the public to stay away from the contaminated area on the 3rd, and said that wildlife rescue efforts have been made. According to reports, the dead birds and marine life corpses caused by the oil spill have washed up on the shore on the morning of the 3rd, and the first injured birds were sent to the local ecological and animal protection agency at noon on the same day.

The main reason for the accident is that many of the facilities inside are aging, and it is also caused by the improper operation of some personnel and the weather.

It is the situation caused by the aging of the oil pipeline, because the oil pipeline is aging, there will be problems, and then it will lead to the leakage of **.

It is because their pipes are aging and the operation is not very good, so it caused such an accident.

It is likely that the pipeline is aging and caused by improper operation, so it is necessary to be very careful in the management of these resources.

The cause of the accident is under further investigation, and the situation at that time was very bad, and the consequences were very serious, causing very large economic losses.

With FG oil adsorption particles, the oil boom can be floated on the water surface, and the polluted oil can be surrounded in a circle, reducing the area and preventing its spread. When the contaminated area is enclosed by the oil boom, the clean-up professionals can throw "adsorption particles" into the contaminated area, and when the white adsorbed particles change color, they can be scooped up and removed with appropriate tools. Or use a mesh with a smaller pore size than the adsorbed particles to enclose the blackened adsorbed particles into the net, and then put away and remove them.

The adsorption particles that absorb oil are convenient for packaging and transportation, and can also be used as fuel waste according to regulations. After the water surface polluted by the oil spill is adsorbed by adsorption particles, the water surface will become clean and oil-free, which meets the requirements of environmental protection.

At present, the main methods to deal with oil leakage in the sea are: the oil boom will fence up more **, and then suck into the working ship; For a small part, ** is decomposed into very small molecules into water by degreasing, but this method is harmful to both animals and plants, and it takes a long time for seawater to digest and decompose.

After the oil spill, from the perspective of environmental protection, we should first do two aspects of work: 1. plugging the oil leak; The second is to remove the existing oil spill. The most desirable way to remove an oil spill is to be quick, easy and to minimize environmental impact. As for the reuse of oil spills, that is a secondary issue.

In addition, the mixture of oil and water can be separated, which requires a special process. Evaporation alone is not enough, because not to mention the low efficiency of evaporation, some components in the oil themselves will evaporate, and some oil and water will form emulsions, which is naturally difficult to separate.

Oil spills, oil spills, and oil spills in the world's oceans are increasing unabated due to a variety of reasons, and the pollution and damage to the marine ecological environment are also serious and long-term. The top priority is how to deal with and eliminate this pollution, but there is no completely effective way to do so in the world. Nowadays, people commonly use three categories: physical, chemical and biological methods.

Physical methods include interception and skimming and adsorption methods; Chemical methods include combustion and chemical dispersion; At present, the most commonly used biological method is the swallowing method.

It's all traditional, all with limitations, and it's good to be innovative.

The spill in southern California, USA, has polluted 35 square kilometers of sea, and now the local emergency management department has begun to use special means to thwart soil invasion into land. Judging from the current report given by the oil company, the reason for this disaster is mainly because all the pipelines have been in disrepair and have been damaged, resulting in ** leakage, and today we will ** take a look at this disaster. <>

First, what are the details of this accident that deserve our attention?

This time the leaking pipeline is a Gulf oil pipeline near Orange County in the southern region of California, about 5km from the coast, where there is an offshore drilling rig that has been around for about a decade. In fact, it can be seen from here that this drilling platform is very old. <>

Second, what is the current extent of the impact?

From the report of the United States, it can be judged that about 470,000 lives have been leaked, or the area has reached 35 square kilometers, and the most serious thing is that it has now begun to drift along the ocean currents on the coast of the United States. As can be seen from the latest developments, the ** dynamics can be detected at 65km south of Los Angeles. It can be seen from here that the current ** leakage disaster is still very serious, and about 3,000 birds have been victimized by this ** leak.

Third, how to solve the ** leakage problem this time?

The U.S. Coast Guard said in an interview that they will drive away nearby birds in the next period of time, and at the same time, they will work with oil extraction companies to set up a special investigation team to repair the pipeline this time. During this meeting, they also pointed out that there are many old pipelines in this bay, and some of them were built in the 40s of the last century, and if they lack maintenance, they will cause more pollution accidents, so they hope to carry out a large-scale remediation of this sea area.

In November 2002, the Liberian-flagged tanker Prestige disintegrated and sank off the coast of northwestern Spain, spilling at least 10,000 tons of heavy oil. Thousands of kilometres of coasts in France, Spain and Portugal have been polluted and tens of thousands of seabirds have died.

In November 2007, the Russian oil tanker "Volga Oil 139", loaded with 4,700 tons of heavy oil, encountered strong winds in the Kerch Strait, disintegrated and sank, and more than 3,000 tons of heavy oil leaked, causing serious pollution in the sea area.

Total was awarded 200 million euros in 1999 oil spill In July 2000, Petrobras' 4 million liters** leaked into a tributary of the Iguazu River.

On 31 March 2001, an oil spill off the coast of Denmark endangered a large number of seabirds, and on 18 November 2002, an oil tanker spill spread and pollution spread to the north-west coast of Spain.
