Carbon dioxide will be stored for stones

]new methods of scientists working on methods to store carbonated. Peridotitis and basalt stones are seen as a solution.
[[T]] Over the world, 30 billion tons of carbon dioxide is release into the air. Many scientists work on methods to store carbonated. Currently the most safe way to harmless, mixed carbon dioxide in mineral. [[[T]] [Deutsche Welle announced they found a solution to this topic of two geological experts in the US, according to the news contained on the website of Welle. [
The scientists believe that the carbon dioxide can be stored in the peridotitis stone, which is located in Oman and is a kind of magma stone. This is noted that the annual release can be stored in 10 percent.

Peter Kelemen is a challenge who is always interested in how stones react against liquid and air. If the colleague Jürg Matter is a water slide. Two geologists are working at Lamont Dahorty World Observatory at the University of Colombia in New York.
Scientists have been researched in Umman for many years interested in each other. But the dual found that the peridotitis stone can be used in storage as a team. The peridotitis stone, normally under 20 kilometers of the floor, is located on the surface in the deserts.
Peter Kelemen, when you break the properties of stones, it is often a pleasant green color. People who make jewelry also takes a green stone. But if you see in nature, it is a red color appearance with rustic. What makes the stone private, in fact, the stone belongs to the depths of the soil and not to be seen too much on the surface. Thus, it shows a very hard reaction to the face of the air and water, and explains with the words ".
Jurger Matter, in fact it is called a natural process to react these stones show, and “This process carries the name of solving. But with this study, we have determined that carbon dioxide retention in physics is faster than we thought. Perhaps in year one, carbon dioxide is critten by these stones from 10 thousand to 100 thousand tons. It’s much faster than we think.

The process of keeping the carbon dioxide in the mineral is quite quickly understood from geological proxies. But it is necessary to speed up the process to ensure a continuous carbon dioxide.
This is also possible with heat. The movement occurs in this way: a hole is opened at about 15 cm in depth of 1 kilometer. And so the peridotititis stone in the deep is destroyed.
The stone is heated by pumping hot water or hot carbon dioxide as the next step. Ideal heat is 185 degrees Celsius. Stone takes part of heat during chemical response. The process should be activated only. And then all obstacles in peridotitis is used and the carbon dioxide is pumped down until the return to carbon dioxide.
Stone will be automatically destroyed during heat and chemical response. There is no need for the help of very expensive vehicles in this process. At the beginning of Babylon models on the computer, the process works such. [
Science states that only in Umman can store 4 billion tons of carbon dioxide. Yet this rate is 10 percent of the annual carbon dioxide absorption. The trials are styles for hanging and making a pilot project.

Umman outside, Papua is the only place with the new Gine peridotit. New Caledonian island groups in Balkans and Pacific are on the surface.
Another stone was recorded that volcanic basalt stone is also conducive to carbon dioxide storage. Jürg Matter researches on the basisalt stone in Iceland with a team of American-Islanda and French scientists.
The first carbon dioxide to the cement stone will inject in the spring of 2009. Continuous carbon dioxide will be pumped for 6 to 9 months following this.
[email protected][After that is about 2 years of observation process. Scientists want to know how much carbon dioxide will cost storage. Matter discusses that method is very early to face with others. [
Matter, “We want to permanently store carbon dioxide and this can only begin with stones such as bassalt or perido stones in Oman. We are interested in two solutions. And solutions will be regional; it is important to have many possibleities to keep carbon dioxide. Carbonized problem is very large and needs all solutions. This is not about the best or most economical solution. Many solutions need“ says. [
