Chapter 347 Desalination of seawater

Chen Jin's design is quite good and the feasibility is very high.

However, "Yueshou Medical" technology, he does not intend to promote it immediately.

The nutrition cabin technology for cultivating infants in vitro is ethically controversial and even difficult for many people to accept... It may take three to fifty years for people to gradually accept.

There is no resistance to the life extension technology.

Five years.

After Chen Jin considered five years later, the first Xinghai Hospital was built in the desert, and the life extension technology could be made public.

In addition, one thing is that after the desert area contracted by Xinghai Technology reached 500,000 square kilometers, the remaining desert will no longer allow Xinghai Technology to contract, and no more money will be spent. This is the upper limit of Xinghai Technology's contracted land.

This is not expected to express any dissatisfaction in Chen Jin’s expectations.

"The 500,000 square kilometers is completely enough. It is impossible to round all the deserts... it will not be allowed."

“This is equivalent to the area of several provinces. It takes a total of 50,000 to 10 trillion yuan to renovate.”

"Most of the profits that Xinghai Technology will earn in the domestic market will be invested in this desert... It is estimated to be barely enough."

Thinking of this, Chen Jin shook his head.

A few years ago, Xinghai Science and Technology entered the desert. Xiaojia He Jia was very interested. He said that he had found the meaning of life and wanted to contribute to the cause of environmental protection. Now that the market is cold, capital has been withdrawn, and her heart has cooled down. Did not talk about this.

Now, the liquidity in the hands of Xiaoyan should be more than 20 billion?

"The timing is basically mature, and those idle funds can absorb a wave."

However, these funds are not used in the domestic desert.

......

20X8 years, May.

Africa, the Sahara Desert.

Morocco, the eastern coast, there is a research institute for seawater desalination - Xinghai Desalination Research Institute.

This day, Chen Jin made a video call and asked about their recent research.

"Professor Bi, how is your research on nano-molecular permeable membranes? Is the production efficiency and cost of fresh water more advantageous than other methods of desalination?" Chen Jinwen.

There are many ways to desalinate sea water:

There are common distillation methods. Among them, high temperature and low temperature distillation are combined, high temperature distillation is high, and low temperature distillation is more energy efficient.

There is a freezing method. The fresh water in the seawater is separated by low-temperature icing.

There is a solar energy law. The solar distillation method uses a simple solar distiller consisting of a water tank with a black porous felt-filled floating hole. The top of the tank is covered with a transparent, edge-closed glass covering. The sun shines through the transparent cover to the black insulated bottom and converts it into heat.

There are multi-stage flashing methods. Flashing refers to the phenomenon that part of seawater evaporates rapidly under the condition that the pressure of seawater at a certain temperature is suddenly lowered. The multi-stage flash seawater desalination is to evaporate the heated seawater in sequence in a plurality of flash chambers whose pressure is gradually lowered, and condense the steam to obtain fresh water.And membrane permeation method. This method is often referred to as the "ultrafiltration method".

The method separates seawater from fresh water by using a semi-permeable membrane that allows only solvent to pass through and does not allow solute to permeate. Under normal circumstances, fresh water diffuses through the semi-permeable membrane to the side of the seawater, so that the liquid level on the side of the seawater gradually rises until it stops at a certain height, and this process is infiltration. If an external pressure greater than the seawater osmotic pressure is applied to the seawater side, the pure water in the seawater will reverse osmosis into the fresh water.

The biggest advantage of the membrane permeation method is energy saving.

The above several methods, the key research of Xinghai Science and Technology, is the "membrane infiltration method".

For no other reason, one is cost; the other is efficiency... Other desalination methods have more or less defects, but the membrane permeation method can take both into account.

“The standard for achieving large-scale applications is Mr. Chen.”

Professor Bi Yongfu said in the video: "I have been fighting in this field for nearly 20 years and now I see the hope of eradicating the "desert" of this kind of cancer on the earth."

“A large-scale desalination unit, using the 'Bi's nano-permeable membrane' produced by Xinghai Technology, can ooze 12 tons of fresh water per second, and produce more than 1 million tons of fresh water per day... enough for a city with a population of one million. ”

"With 100 sets of such desalination devices, it can solve the survival needs of 100 million people."

"If you build 1,000, the entire Sahara desert can become a land full of vitality."

“And such a desalination plant has a construction cost of about 1.5 billion yuan per unit. In the process of producing fresh water, the average electricity consumption per ton of water is about 1 degree.”

"Assuming the electricity bill is 3 cents, and then the cost of pipeline construction, management and maintenance, the average desalination cost per ton of fresh water will not exceed 3 yuan / ton."

"This is more expensive than direct pumping of fresh water from Lake Baikal, but it is not too expensive and is within the tolerance."

“Chen Chen, I suggest buying the desert here and developing it with the company’s most advanced desert control technology. I believe that in just one or two decades, we will have a large oasis!”

“Xinghai Technology will become the world's largest land contracting company, and only those land will bring huge profits to the company.”

Chen Jin nodded.

Fresh water 3 yuan / ton, all costs are included, this price is really good, to reach the standard of mass production.

During this time, Xinghai Technology also sent commercial representatives to conduct commercial negotiations with North African countries such as Morocco, Libya, Algeria and Niger, and purchased 1.5 million square kilometers of desert... The total cost is about 150 billion yuan (the money is Xinghai Technology Profits obtained from overseas business activities).

All signed are permanent contractors.

The desalination technology is now mature.

Xinghai Technology can open its arms and do a great job in the Sahara Desert.

But the timing is not yet fully mature.

......

May 29th this day.

In the virtual world.

"Alice, what is the result of the vote? Is there any problem with re-election?"

Chen Jin asked with a hand."The vote rate was 82.17%, and there was no suspense for re-election, and created the highest re-election support rate in history." Alice said.

"But I see the media is very fierce. The mainstream media has almost no support for Langfro. It is completely one-sided. It has also done a lot of online polls, saying that the probability of re-election is less than 1%... ”

"Fake news owners, these are false reports, but the final vote is true, this is the only merit of this system."

Alice said again: "In addition, the master has to add a batch of bodyguard robots to Langfro, the number of people is best doubled. From the beginning of this year to the present, Langfro suffered 187 assassinations, an average of more than once a day, I think This frequency will increase in the future, the means will be more intense and extreme, and we must be better prepared."

To know those who have lost their interests, they will never give up.

"I rub, 187 times?"

Chen Jin shook his head. This is just beginning. When the next step is launched, isn’t the frequency of assassination even more crazy?

It seems that in addition to the avatar robot that can't die, in general, God can't save M.

Recommend a friend a book "捡到一修修界界", cool text, feels pretty good, you can look
