Chapter 354 Selection of desalination schemes
Seawater desalination is a world surname problem, that is, the salt in the seawater is separated, leaving only pure fresh water, with the lack of water resources, originally only desert countries have spent great efforts to study, and now it has become the focus of many countries and institutions in the world to study the key subject, although great progress has been made, but energy consumption and unit price are still the key factors restricting this technology.
Whether it is distillation or freezing method has huge defects, high energy consumption, the efficiency of distillation is too low, and the fresh water produced by the frozen method has a salty taste, not suitable for direct drinking, until the invention of reverse osmosis method, the cost of seawater desalination has been greatly reduced, under the same circumstances, reverse osmosis method is only one-fortieth of the distillation method, in the area where there is a lack of fresh water, it has the conditions for large-scale production.
Just when the reverse osmosis method was popular in the world, the distillation method has also been improved, re-entered the world's vision, originally needed to be heated to the boiling degree to separate, not to mention the energy consumption, the scale produced after the evaporation of seawater is also a great trouble, now by reducing the air pressure can achieve the same purpose, and the energy consumption is very small, the same in line with the requirements of large-scale production of fresh water.
And if the distillation method is combined with the thermal power plant, the residual temperature of the thermal power plant can be used for heating, so that the cost is lower, slowly, more and more desalination plants use this distillation method, but the reverse osmosis method still has its own characteristics, so there is no obvious superiority or inferiority.
In the Middle East, most countries use the method of seawater desalination to obtain domestic water, that is, the United States, France, Britain, Germany and other developed countries have also paid more and more attention to the geological damage caused by a large number of groundwater, and most of their big cities are by the sea or not far from each other, and it is more convenient to use seawater desalination technology as urban life and industrial water.
Although the reverse osmosis method also has many advantages, the new distillation method is still the first choice for large-scale or super-large desalination plants, and the development is now the most mature technology, the highest safety, and the thermal power plant is more convenient, only those developed countries, in the case of no thermal power plant, the reverse osmosis method is used.
Su Ming prefers to use the combined method of thermoelectric distillation, but there is no resistance to the reverse osmosis method, anyway, these two technologies are in the hands of some professional companies in Western countries, so simply bid for it, and draw up a project tender with an output of 200,000 cubic meters and a second phase of 300,000 cubic meters.
Namibia has abundant uranium resources, but the investment in building a nuclear power plant is too large, and the cycle is too long, and the technical requirements are too high, now the key is that time waits for no one, so we have to build a thermal power plant first, just because Anko has rich oil resources, there is a large oil field near the Namibian border, and only need to build a pipeline of more than 100 kilometers to lead to the refinery here.
After the tender was issued, several very professional companies in this field did not move for a long time, but there were countless small companies coming over, because Su did not have professionals in this area to check for Su Ming, Su Ming had to go into battle in person, and the result was quickly angry.
The technology of these companies is also within the scope of those types, but no matter how powerful the technical strength they boast of, Su Ming still immediately heard that they are some deceitful guys, buying some professional equipment in other professional companies, and replacing them with cheap or poor standards in other places.
Even in China, there are two companies coming over, one plays the emotional card, and the other doesn't know how to find Song Dacang, so Song Dacang writes a note, but unfortunately the two have no similar construction experience at all, and the technology is extremely backward, when Su Ming told Song Yuqian, Song Yuqian was stunned for a long time, and didn't remember who this person was, and asked his father to know that this guy was a distant cousin of his own, I don't know how to learn the news, and heard that Song Dacang was showing off his relationship with Su at home, so he begged him to write a note.
Hearing this, Su Ming had a little idea, that guy Su Ming has also seen it, he is quite shrewd, and he can find business opportunities from the one-sided news, and he is quite business-minded, his company is not a regular company, Su Ming asked Song Yuqian to contact that guy, let him give up the company, come over to assist in this bidding incident, and when the bidding is over, he will be sent to Luo Shaojun's men, with his kind of mind, it is quite suitable to do trade work.
After the development of the Su trading company to a certain extent, Su Ming transferred Luo Shaojun to the trading company to take charge of the company, just to give full play to his talents, the trading company is also under his leadership, has achieved rapid development, China's light industrial products and ordinary goods are still in the first large-scale entry into the southern African market, low profit prices are very popular with the general public.
Of course, the abundant minerals and a variety of specialties here are also very popular with the domestic market, Europe was originally their market, although there are original channels, but the transportation is the route of Su's, the previous paragraph, there is even a very high standard of the American Chamber of Commerce came to Su Ming to ask Su Ming to open a route from here to New York.
Now even if the three routes are made in both directions, only six An-124s are needed, not to mention that the two routes from Longjiang to Hamburg and Hamburg to here do not need two planes at all, and if they are opened, it is better to open a Europe to the United States and China to the United States at the same time.
In this way, six planes were used for the six routes, and the remaining one was used as a backup and temporary call, and the American Chamber of Commerce promised to ensure the safety of Su's aircraft, and at the same time set up a guarantee clause, if the business was insufficient, the Chamber of Commerce would be responsible for the loss.
As soon as they agreed to their request to open a route, the chamber of commerce came to the door again and recommended a company of their own to participate in the bidding for the desalination project, although they used the reverse osmosis method, but promised to build a thermal power plant for the Su family at a very favorable price.
At this time, a British company also came to the door, the same reverse osmosis method, the same conditions for the construction of thermal power plants, the two seemed to have negotiated, the price was about the same, much higher than those small companies, Su Ming then knew that the small companies that came before were dependent on these large companies to survive, like this kind of construction site is relatively remote or relatively backward countries, usually these large companies are not willing to participate directly, but to these small companies to do.
Su Ming was reluctant to use the reverse osmosis method, so he continued to wait, and at this time, suddenly a company came to the door and proposed a more novel and cheap method, which was to use a tugboat to go to Antarctica to drag icebergs to turn into fresh water here, which aroused Su Ming's interest.
There are a lot of icebergs in Antarctica, and there are often large areas of icebergs peeling off from the Antarctic ice sheet, which poses a great danger to navigation, and the most important thing is that it is very close to Antarctica, and small icebergs can often be seen floating over, which is also a way, although it can not be used for a long time, but short-term emergency relief is not a problem.
And the company also said that the contract could be signed in a single way, and Su Ming was about to sign an agreement with the other party for ten icebergs, and first get it to quench his thirst temporarily, but when he looked at the agreement, he didn't see the follow-up treatment plan for the icebergs.
When Su Ming looked at the representative of this company with doubtful eyes, the person from the company said that they were only responsible for dragging the iceberg over, but not for other things, Su Ming immediately waved them to leave quickly, and he wanted to kick people a second later.
Who doesn't know that it's easy to drag the iceberg over, but it is difficult to deal with it, the smallest iceberg is also a few kilometers square, how to cut it is a problem, and if you wait for the iceberg to melt naturally, it will take a few years, some data show that even in the tropics, it will melt at most about ten meters a year.
Almost deceived, Su Ming was depressed, and suddenly received a good news, a French company and two German companies jointly participated in the bidding, two of these three companies are professional companies in seawater desalination, and the other is a chemical company.
In the plan of the three companies, the method of combining distillation and reverse osmosis is adopted, but it is flexible to use one technology alone, or two can be used at the same time, and the combined power generation project is also in the plan, and the salt can be treated to make industrial salt.
Su Ming looked at the plan again and again, and felt that this plan was very suitable for his own needs, the fresh water from the simple reverse osmosis must also be post-treated before it can be used as drinking water, but there is no problem when it is used for industrial water or urban facilities, and the pure point of the water from the distillation method can just be used as domestic water, and the two schemes can also be combined to make different levels of fresh water according to different needs.
However, the budget of this plan is also one-third more than a simple plan, Su Ming has repeatedly decided to use this plan, but the thermal power plant needs to be built by itself, Su Ming is ready to use a large dual-energy engine as a generator, can use fresh water as fuel, and the electricity generated can produce more fresh water, even if his own fuel plant is successfully planted, it can also be used, as for the oil brought from Angola, it can be used in the form of multiple pipelines to ports and airports.
Su Ming is ready to wrap the generator set with layers of isolation layers like a nuclear power plant, except for the external display status, there is no need for the staff to enter, and the dual-energy engine can be made without doubt, the pipeline goes straight underground, who knows whether the water used is still oil.
After reviewing this plan repeatedly, Su Ming signed his name on the plan, even if it does not count the cost reduction of the power plant, the cost per cubic meter is less than four dollars, and the cost of four dollars is a dilution standard, which is already lower than the price of fresh water in ordinary ways, of course, in Africa and the Middle East, this price is higher, but when it is declared to the outside world, it must add the electricity consumed, and the cost is more than five dollars.
