In central Saudi Arabia, there is a city called Ghajar.
This is a large-scale seawater desalination plant. On one side of the huge reservoir, four PVC pipes with a thickness of one meter are gurgling with seawater. The other end of the pipes stretches for hundreds of kilometers, like a giant water-absorbing dragon.
In the depths of the Red Sea, several water pumps continuously pump seawater from the reservoir into the filtration workshop, and filter the seawater through the super filtration membrane. When the water flows out of the filtration workshop through the water channel, it is no longer bitter, but becomes
It is sweet and delicious, and can be used for drinking and irrigation.
With the help of a large amount of fresh water produced by seawater filtration, an oasis has been formed in the originally sparsely populated Gezar Desert, and the city of Gezar has become a prosperous city. Prince Flandin is now the lord of this city.
and all the properties in the surrounding oasis belong to him.
"Look, this is the factory you helped us build. Without your desalination technology, I simply can't imagine that Gezar would have such lush grasslands."
Flandin accompanied Qin Hai and his entourage as they walked in the seawater filtration plant area, happily introducing to them the changes in the Gezar Desert over the years.
Qin Hai met Flandin ten years ago. At that time, due to an oil spill from an oil tanker off the coast of France, Flandin almost went bankrupt. Qin Hai used the super filtration membrane he developed to solve the problem of seawater purification.
The problem helped Flandin get out of the predicament. After that, Flandin invited Daqin Group to build this seawater desalination plant in his territory, the Gezar Desert. This plant also became Daqin's best seawater filtration technology.
Demonstration sample.
It has been seven or eight years since the factory was built, and this is the first time Qin Hai has visited the factory. Before that, Flandin had sent out many invitations, and Qin Hai had also agreed, but due to various reasons
The trip failed to take place due to various reasons. However, the economic ties between the two parties have never been interrupted. Flandin purchased filter membranes from Daqin Group, while Daqin Group purchased crude oil from Flandin. The two parties are very close trading partners.
Seawater desalination is achieved by relying on filter membranes, which are consumables. Every year, Flandin pays Daqin Group to purchase filter membranes worth tens of millions of dollars. Only the Saudi oil tycoon has such confidence.
Turning into poor countries like Jordan and Yemen is absolutely powerless.
As for the oil purchased by Daqin Group from Flandin, the amount is even larger. The annual crude oil trading volume between the two parties reaches more than 10 million tons, worth three to four billion US dollars. It can be said that the buildings in Gezar City
Half of it was built with money paid by Daqin Group.
Qin Hai came to Saudi Arabia this time, on the one hand, to negotiate a crude oil supply agreement with Flandin for the next ten years to ensure the supply of crude oil for the rx project that is about to be put into production. On the other hand, he came to promote Daqin Group's new product to Flandin.
Technology, to put it harshly, is just looking for rich people to fight against the autumn wind.
"Prince Flandin's courage is indeed admirable. Although I have never been to Ghaizal before, I heard from the employees of the group who went to Ghazal that ten years ago, Ghazal was a complete desert and there was no sight.
What green? Now, the oasis around the city is almost ten square kilometers, right?" Qin Hai asked in an appreciative tone.
"It's a full 15 square kilometers." Flandin said proudly. "The environment is completely comparable to Europe."
"Not bad, not bad." Qin Hai said, "In ten years, it has increased from almost zero to an oasis of 15 square kilometers. This is an amazing achievement. I believe that in another ten years, this oasis will definitely grow to 150 square kilometers."
A square kilometer is enough to attract the attention of the world.”
"This... I'm afraid it's a bit difficult." Flandin looked embarrassed. Of course he believed that Qin Hai's words were sincere, but he himself did not have such great ambitions. The amount of water evaporating in the desert area is extremely large.
.Relying on seawater desalination for irrigation, maintaining an oasis of 15 square kilometers is already an amazing feat. If the oasis is to be expanded to 150 square kilometers, he will need to build 10 more similar desalination plants, annual electricity bills, and filter membranes
Consumption, labor costs, etc. are all astronomical figures. No matter how rich he is, he cannot afford such consumption.
"What? Isn't the surrounding desert your territory?" Qin Hai pretended not to understand what Flandin meant and asked in surprise.
"Of course, even a larger area belongs to me." Flandin said, "However, the economic pressure is too great to continue to expand the oasis."
"Desert greening is a global problem. If it can be satisfactorily solved by Prince Flandin, then you, Prince, will be famous in history." Qin Hai continued to drink the enchanted soup.
Flandin nodded: "I know this, but the water consumption of the oasis is too large. Don't look at the fact that my factory can produce nearly 10,000 tons of fresh water every day. Compared with the water consumption, it is not worth mentioning.
Most of the oasis plants outside our city are drought-tolerant plants, otherwise water consumption will increase by more than three times."
"We have a tropical desert climate here, and the amount of evaporation is much greater than that in China. We can only water the plants at night, and all the water will evaporate as soon as the day breaks." Flandin's assistant Dredge
Explained to Qin Hai in a low voice.
"So this is what you are worried about." Qin Hai seemed to have just understood this question. He smiled and pointed at Engineer Yu Lihong who followed him and said: "I ask Engineer Yu to ask you about this question."
Explain."
"We invented a highly water-absorbent polymer material that can be used in the desert to retain water and ensure that the water used for irrigation will not evaporate." Yu Lihong couldn't wait to tell Flandin and Dredge, even before it was too late.
Make some preparations.
"What do you mean?" Flandin and Dredge were both stunned. After arguing for a long time, Qin Hai said that he wanted to build an oasis of 150 square kilometers. This was not a polite word, but a plan.
Yu Lihong didn't care about the attitudes of the two people. He gestured with his hands and said: "The product we invented is a small particle, about the same size as a grain of rice. Mix it in the sand. Once there is moisture in the environment, it will
It will absorb water into its body, and its volume will increase accordingly, which can reach up to 10 times its original volume. When the external environment becomes dry, it will gradually discharge the water and provide it to the surrounding environment.
Plants. This way, you don’t have to worry about the water evaporating when you water them.”
"In fact, the principle is similar to that of baby diapers, except that we have lowered some cleanliness requirements and at the same time reduced the cost to an acceptable range." Qin Hai added on the side.
"Have any tests been conducted on the effect of this kind of particles?" Dredge asked seriously.
"Of course we have." Yu Lihong said, "We have specifically conducted experiments in desert areas in China. After using these particles, the water in the sand can be maintained for more than a month, which can fully meet the water needs for plant root growth.
"
"So, what's the cost of use?" Dredge asked again.
"In terms of cost..." Yu Lihong hesitated.
"The cost is completely affordable." Qin Hai took over the topic. He knew that Yu Lihong, an honest man, wanted to tell the truth again, so he had to interrupt him quickly.
"The annual consumption per square kilometer does not exceed US$50,000, and experts have calculated that after 10 years of use, the local vegetation will have solidified, and then there will be no need to use this kind of particles to retain water." Qin Hai
said.
US$50,000 per square kilometer is equivalent to 400,000 RMB. This is of course a heavy expense for China. China has millions of square kilometers of desert area. Even if such particles are used on 1% of the area,
The cost is also several billion yuan. It is better to organize manpower to plant grass and fix sand as we do now. But for Saudi Arabia, the situation is different. This is a country with an extreme shortage of labor and too much money to put. 10 million
What does the dollar mean to an oil tycoon like Flandin?
Sure enough, when he heard that the annual consumption per square kilometer was only 50,000 US dollars, Flandin was a little tempted. Being able to expand the area of the oasis was of course a great thing for him. Qin Hai planned a 150-square-meter area for him.
According to this long-term plan, it will cost US$7.5 million a year, and it will be enough to sell one or two million barrels of oil.
"This is a good idea." Flandin laughed, "Mr. Qin, I am willing to accept your suggestion. Please arrange for engineers to do detailed planning."
"Great, I knew Prince Flandin would be satisfied." Qin Hai smiled.
"It seems that the purpose of Mr. Qin's trip is not only to sign the oil import agreement, but also has other ideas? This gentleman is engaged in super absorbent polymers, so this gentleman and this lady, they are engaged in
What about it? Mr. Qin, can you introduce it to me?" Flandin pointed at Qin Hai's other two attendants and asked.
"I was just about to introduce you." Qin Hai said, "This is Mr. Ka'an, a tenured professor at the Anhe School of Materials. He was originally a professor at the Brazilian Institute of Aeronautical Technology. He was the inventor of the world's first graphene supercapacitor.
The inventor. As for this lady, she is my wife Ning Jing, who is now a researcher at the Superconductivity Research Center of Kyungseong University."
"Prince Flanding, it's a pleasure to meet you." Ning Jing took a step forward from Qin Hai, bowed to Flanding gracefully, and said, "I want to especially thank you for the diamond ring you gave to my husband.
Because he forwarded it to me again. This time Mr. Kaan and I came to Ghazal with my husband to introduce you to a great idea of Mr. Kaan, which is lightning collection. I think if we talk about the whole world
Who is most interested in this technology must be the discerning Prince Flandin." (~^~)
