2501: C2501 Helium Extraction

C2501 Helium Extraction

"Coming, coming!" At this moment, a car carrying an air bottle drove over. It was an ordinary van. The back door of the van flipped over. The air cylinder behind the van was revealed. There were two sky blue air cylinders. Half of them were exposed, and the engine of the van rumbled. It was speeding towards them.

In the development of the country's economy, it was inseparable from the transportation industry. In the transportation industry, all kinds of vehicles had their own roles, heavy trucks with large horsepower, and so on. They were mainly driven on long-distance transportation routes, while light vehicles... In short-distance transportation, they were used for short-distance transportation. The van was also one of the best, it could pull people, it could carry goods... It was definitely a good helper for making a fortune.

The steel plate hanging from the back, coupled with the rear wheel drive, gave it a powerful load capacity. Don't look at how small the van was. When needed, it could even carry two tons of goods.

Qin Guan watched as the car drove over. The words Haihe in front of the car was quite dazzling. This kind of car was produced in their own Haihe Automobile Factory. The sales were very large, and the yellow shell was a beautiful scenery.

The car was here!

The few of them raised their hands together and carried the cumbersome helium steel bottle into the cabin of the airship.

If it was a hard shell airship, there would always be a big thing on top. This was quite inconvenient, but now it was all mollusks. The airbag on the airship was deflated before it was inflated. The first test flight was directly folded and placed on the upper end of the cabin. So now it seemed that the airship was just a mini bus like device.

Qin Guan looked at them installing the helium steel bottles in high spirits and asked in confusion, "Why didn't you prepare this beforehand?"

Preparing in advance? Hearing Qin Guan's question, the person in charge had a guilty look on his face. "It's not that we didn't prepare in advance. Our helium airship test flight. We have been waiting for this helium until today to get it. That's why we decided to test it today. "

"I just got it today. Is this thing very difficult?" Qin Guan asked.

Qin Guan was in charge of commanding the big scene. He had all kinds of strategic weapons. He often used hundreds of millions to negotiate contracts. Therefore, Qin Guan did not expect this little helium to be so difficult to produce.

"Yes, there is very little helium industry in our country. Most of the helium is imported." The person in charge said.

One. The small air bottle was actually from the ocean, which piqued Qin Guan's interest even more. "What's going on? Is the technique required to make it very high? Can it be extracted from the air?"

The liquid nitrogen and liquid oxygen that Qin Guan knew were all extracted from the air. When the air was compressed and compressed, it could be liquefied, depending on the liquefied temperature of different gases. It was very easy to extract the liquid oxygen that was needed in the rocket. That was how the oxygen needed in the industry was done.

As for the helium, it belonged to the category of inert gases. There was very little content in the air. It probably could not be used in this way, right?

"Extracting it from the air is too inefficient. If it's used in the industry... It's all extracted from natural gas. " The person in charge naturally knew a lot about this. Now that Qin Guan asked this question, he began to explain.

"At present, the international cold condensation method is still commonly used. Use natural gas as the gas source, and first use chemical methods to make hydrogen sulfide, carbon dioxide, and water in the gas source. Even the impurities such as mercury are purified before entering the low-temperature device. After the second condensation, the helium content was about 60% thick. Among this thick helium, the main magazine was hydrogen. This gas needed to be further removed. After a few rounds of purification, finally, the helium with a purity of over 99% is obtained. "

This method was indeed complicated. Qin Guan nodded seriously. "Then, is the production of this helium in our country very low?"

" There is a portion of thick helium. High purity helium, we rely on imported. " Yes, the person in charge said.

Qin Guan nodded and looked at the cylinder. He also knew how heavy the pressure on his shoulder was.

Industry was all-encompassing. It was not easy for him to take into account every part of it. If he had not come here, he would not have known about the industrial production of helium. It would be a difficult problem for him in the country.

It seemed that he had to push for it.

After all, apart from using the helium on the airship, it could be used in many places, even in the military.

For example, the guide of the Infrared Missile used the helium to cool it down. A lot of welding of metal materials were welded under the protection of the helium. If the oxygen nitrogen gas inside the submarine was neutralized by a certain amount of helium, it could effectively prevent nitrogen poisoning when nitrogen exceeded the standard. The sealed Launch Box of the Strategic Missile needed to be infused with helium to neutralize oxygen. It could be used for maintenance and fireproof and explosion-proof purposes...

The helium industry in the country was quite backward. Hence, if there were special circumstances, it would be restricted.

"In the past, our helium needs would not be delayed. We could import large amounts of helium from Y Country at any time, but since last year, Y Country has sanctioned our exports of helium. They have strictly guarded against the usage of the helium in other areas. Therefore, our helium is imported from Bear Country at a high price." The person in charge continued.

Just like the electronic technology of Kimchi Country, it seemed very advanced. However, after R Country cut off a few of the raw materials, the production line of Kimchi Country immediately fell into a crisis of suspension. Although Han Country had a vast land and a complete industry, it still had its shortcomings. If this shortcoming was not supplemented, it would be very easy for others to choke on it.

No wonder they had been waiting for the helium. The helium imported from overseas was very expensive and there was not much of it. Under the circumstances of prioritizing the military, there were very few that could be used on civil projects like theirs.

It seemed that they needed to quickly build a sufficient helium extraction factory in China! This matter would be arranged soon!

"Start inflating!" After the installation of the gas bottle, the person-in-charge shouted loudly. It was finally time for the most exciting moment!

Inside the gas bottle, the helium looked very small. Now, the helium was flowing into the air bag at the top through the pressure reducing valve. The airbag began to expand and expand. Very soon, an elongated water droplet shape appeared!1

The first bottle of helium had already been poured in. Then, the second bottle. The air sac of the airship was completely inflated, and the Rudder Surface at the tail was also opened. The rope that was tied to the ground was also tightened, and the airship was ready to launch!

"Pine rope!"

The ropes were slowly released one by one. As the ropes were loosened, the airship also began to slowly float up, and it flew up!
