Professor Huang is a well-known scholar in China. He is quite busy with scientific research activities on weekdays. This time, he has canceled many meetings and lectures to participate in the trial harvesting of combustible ice. However, he was very happy to hear that there is such a science popularization activity on the Blue Whale.
He agreed.
In his own words: "As a scientific researcher, science popularization activities are also extremely important, so that everyone can clearly understand the importance of science, and can also better understand the great significance of all our work!"
"How's it going? How many people are there?" Professor Huang asked Feng Chen in a low voice.
Although it is just an ordinary science lecture, if there are too few people, it will not look good on you.
"You will know after you go and take a look!" Feng Chen could see the professor's worry.
After waiting at the door, Professor Huang couldn't help but take a breath. He saw that the multi-functional hall was filled with off-duty workers and scientific researchers from various positions on the Blue Whale. There were even people sitting on the floor. This
This situation is not even common in university classrooms. After all, the geology industry itself is not a major that many students are optimistic about, and it is even more unpopular than the four famous "biochemical and environmental materials" pitfalls.
"Everyone is very supportive of science popularization activities, and of course you have the blessing of Professor Huang, otherwise it would not be so popular!"
Although the compliments could be heard at this time, Professor Huang still enjoyed it very much.
"You did a good job in the event!" Professor Huang said happily.
Feng Chen hurriedly took Professor Huang into the "classroom", and the applause immediately became loud.
"Today we, Blue Whale, have the first marine science popularization lecture. We are fortunate to invite Professor Huang from the China Geological Survey. Professor Huang is a famous marine geology expert in my country and has made outstanding contributions to the development of my country's offshore oil and gas resources. Now we once again use Warm applause to welcome Professor Huang!”
Applause rang out again.
"Thank you to the Combustible Ice Trial Mining Headquarters, and also to the Blue Whale, for giving me this opportunity to popularize scientific knowledge to everyone. What I am explaining today is our goal this time, flammable ice!"
As he spoke, Professor Huang signaled his assistant to open the laptop in his hand. It could be seen that Professor Huang was very concerned about this science popularization activity and even made a ppt for demonstration.
"Let me ask you a question first, how much do you know about flammable ice?" Professor Huang asked.
The workers present looked at each other, but none of them spoke.
"Don't be shy!" Feng Chen said with a smile, "This is a popular science lecture, so it doesn't matter if you say it wrong!"
A bold worker immediately said: "Combustible ice is ice that can burn!"
Professor Huang nodded: "This statement is correct, but it is also incorrect!"
"Combustible ice is a common name for natural gas hydrate. It is a crystalline substance formed by natural gas under high pressure and low temperature conditions. It is usually distributed in the deep sea or in the permafrost under the land. Because it looks like ice, it ignites when exposed to fire.
, hence the name "combustible ice", also known as "solid gas" and "air ice"."
With Professor Huang's explanation with pictures and texts, everyone began to have an in-depth understanding of flammable ice.
"Combustible ice was first discovered in the laboratory. More than two hundred years ago, scientists synthesized combustible ice in the laboratory. However, at that time, people did not confirm that combustible ice also existed in nature. Until 1934, people
Burnable ice has been found in blocked natural gas pipelines, confirming the natural existence of flammable ice!"
Professor Huang gave a detailed explanation of flammable ice, and everyone listened with interest.
"Only the discovery of combustible ice minerals was not discovered until 1968 under the permafrost in Siberia, and combustible ice on the seabed was discovered eleven years later in 1978!" Professor Huang drew the time when combustible ice was discovered.
"So, combustible ice is a brand-new energy source, and the research and development of combustible ice is at the beginning stage. Although our country's development of combustible ice is relatively late, it is still at the same starting line!"
The workers and technicians attending the lecture were all talking to each other. Everyone knew that China was lagging behind in the development of energy, especially the development of modern energy. This time, the development and utilization of flammable ice was far behind the world.
The latest advanced level, it is also an excellent opportunity for overtaking in corners.
Professor Huang continued: "Compared with traditional fossil energy, the formation of combustible ice requires very harsh conditions. First, the formation temperature of flammable ice is between zero and ten degrees. It will decompose when it exceeds twenty degrees. Currently, there are only
The permafrost layer on land and the seabed can meet this temperature requirement! This is why flammable ice was first discovered in Siberia, because the permafrost layer there can meet the conditions for the formation of flammable ice!"
"Professor Huang, does my country's Qinghai-Tibet Plateau also have an environment for generating flammable ice?" Someone immediately raised his hand and put forward his own idea.
"Yes!" Professor Huang nodded immediately, "my country's Qinghai-Tibet Plateau also has this kind of environment, and flammable ice was also discovered in some areas not long ago. However, due to the harsh climate of the Qinghai-Tibet Plateau and environmental restrictions, flammable ice Development has encountered considerable difficulties!”
"Compared with the more harsh conditions of the permafrost layer of the Qinghai-Tibet Plateau, flammable ice only requires thirty atmospheres of pressure to generate at zero degrees, and the greater the pressure, the less likely it is to decompose. This is where the seabed has a more prominent advantage!
Moreover, the carbon produced by the decomposition of organic matter deposits on the seabed is converted into gas, which becomes the raw material of flammable ice under strong pressure. Under the combined action of temperature, pressure and raw materials, flammable ice is produced on the seabed!"
"Our country has conducted a large number of marine geological surveys in the past ten years and found a large number of traces of flammable ice. After preliminary drilling, in the Shenhu Sea area where we arrived this time, we found an area of only 100 meters.
More than 150 billion cubic meters of flammable ice are stored on the seabed covering more than square kilometers, which is equivalent to 150 million tons of oil reserves!"
Everyone present was shocked by this huge number. This small sea area alone has such huge energy reserves. If you think about other unexplored sea areas, this number will be even more astonishing.
"The most important thing is that the main component of flammable ice is methane. When burned, it only produces water and a very small amount of carbon dioxide. It has the characteristics of high combustion value, clean and pollution-free. One cubic meter of flammable ice can become zero after decomposition.
Eight cubic meters of water and up to 164 cubic meters of natural gas have high energy density, and as the level of science and technology improves, the resource potential will also greatly increase. Some scientists believe that flammable ice can satisfy the new energy used by humans for 1,000 years.
It is the primary substitute for traditional energy sources such as petroleum and coal in the future!"
Seeing everyone's surprised expressions, Professor Huang was very satisfied with the effect of his popular science lecture. He finally said: "The current world is an industrial era with extremely advanced technology, and the status of energy is naturally self-evident. Energy even
It has become one of the yardsticks for measuring a country's strength, so energy is of very important strategic significance to our country! The goal of our mission is to open a new window for our country's energy development and add strength to improve our country's energy security.
!”
Although everyone had understood the importance of this mission through various trainings and meetings before, when Professor Huang explained it in conjunction with the development of flammable ice, everyone immediately felt the heavy responsibility on their shoulders.
, and feel extremely proud to be able to participate in this project.
