One Thousand Five Hundred Fifty-Seven Turning Waste Into Treasure

And on the other hand, even if you can solve the problem of gas corrosion equipment.

However, in the exploitation of such gas reservoirs, with the technology at that time, how to separate various gases is also a big problem.

The main method at that time was the condensation separation method, which was to continuously reduce the temperature and then pressurize the gas.

In this way, the physical properties of different gases are used, and different gases have different boiling points at different temperatures and different pressures.

These gases will turn into liquids and then separate out at different times.

However, there is a problem with using this method, that is, it needs to consume a lot of electricity.

Because refrigeration must use electricity, if this method was used to condense and separate natural gas in the past, it would be better to say.

After all, the main product separated is natural gas, which is very easy to buy in the market.

Whether it is a factory, a power plant, or an individual user, they like to burn this thing.

So don't worry about selling at all.

As for the helium that finally came out, that's a matter of piggybacking.

But if you separate this kind of gas reservoir by condensation, the most object you get out is actually carbon dioxide.

You do so much with this thing and it's useful?

And now many factories can't use the carbon dioxide they finally produce, so you still have to mine it from the ground?

In this way, the cost of mining and refining is not proportional to the cost of expensive materials such as helium and nitrogen.

So no one wants to exploit such gas reservoirs.

Even now, not many people are willing to exploit such gas reservoirs because the cost is too high.

Even Qin Xiaotian and the others were unwilling.

It is not even as good as importing a large amount of LNG from abroad, and then using flash gas to refine it.

And this gave Xiao Feng a chance. In the eyes of others, carbon dioxide has no effect.

For them, it is a very useful chemical raw material.

The first is the opinion given by cloning experts, this thing can be mixed with a certain chemical substance, and it can be transformed into a very good oil-displacing agent.

What do you mean? It is a crude oil diluent.

It can be said to be very effective when used in oil fields in the Shaanxi-Gansu region of my country, and can even be used in the extraction of crude oil in Venezuela.

As I have said before, there is a lot of shale oil in western my country, but it is not easy to exploit shale oil.

The first is that it is very dispersed in the mantle at different levels underground, and the mixture of crude oil and sediment has turned into sludge.

When we mine, we usually use the fracturing method, which is to use a fracturing truck to follow the drilled pipeline, and then use shock fracturing to connect the fractures in the oil reservoir.

Fill it with a substitute, and the substitute used by the Americans is water, because there is no shortage of water.

But we can't use water, so we can only use another kind of sand mortar as a replacement agent.

These displacers are piped into the reservoir through fractures, and then the sludge is squeezed out and pumped up through the pipeline.

This is the process of our shale oil extraction, because we need fracturing trucks and special replacements, so the price of our shale oil extraction is very high.

The cost is above forty dollars a barrel all the year round, which remains high.

The oil-displacing agent made by cloning experts has a completely different concept from the replacement.

Use this carbon dioxide plus other chemicals to make displacement oil displacement agent.

Its main special effect is that it is easily soluble in crude oil, and once dissolved in oil, it will cause the expansion of crude oil molecules.

The viscosity of crude oil is reduced and the fluidity is enhanced. Under the action of gravity,

Through the principle of capillary dialysis, dialysis can be obtained from the sediment.

In this way, if this technology can be widely promoted, it will greatly reduce the cost of our shale oil extraction.

You must know that after my country's shale oil is exploited, it cannot be directly transported and sent for refining like the shale oil in the United States.

Our shale oil has to go through a process of extrusion, dilution and precipitation.

Because what you mine is sludge, this poop-like mixture cannot be sent directly to chemical plants for refining.

And this extrusion precipitation process is generally carried out near the wellhead.

The principle of this process is like juicing sugar cane.

The sludge waste that has been squeezed is actually very harmful, because it contains a large amount of heavy metals. If it is not treated in time, it will seriously endanger the natural environment.

The responsible company will find a special disposal team to take away these wastes and land them in special places.

On the other hand, in the United States, it is already possible to dilute it directly with other preparations, and then refill it and inject it into the ground.

And it can also reduce pollution to a minimum...

But on our side, obviously we can't do it.

On the other hand, Xiao Feng can also give a perfect solution. They still use carbon dioxide as raw material to make a preparation.

When this preparation, combined with the sludge waste, can also support special briquettes.

These briquettes can then be sent to factories for incineration.

Of course only in factories with CFB boilers, this briquettes would be a very good fuel.

After all, even if it is squeezed dry, those sludges are rich in a large amount of hydrocarbon compounds, which are very flammable substances.

After adding the special preparation for the carbon dioxide process, harmful heavy metals can be naturally precipitated during the combustion process.

And these are unique technologies.

Therefore, in the eyes of others, carbon dioxide, which is useless, can turn waste into treasure when it comes to Xiao Feng and the others.

With such a technology, those large carbon dioxide gas reservoirs will become valuable for development.

You must know that the carbon dioxide gas reservoir under the Hailar Basin is increasing every year.

The main principle is that magma originating from the ground continues to pour upward from the mantle fault zone.

In the process of going up, it continues to cool and turns into granite.

The gas associated with the magma will be trapped by the continuously solidified magma and firmly in the granite layer.

This principle is like the manufacturing principle of the bubble glass.

When blowing glass, I deliberately let the silica lock in those bubbles, and it ended up being a beautiful bubble glass.

And what we have to do is to extract the gas from these bubbles and use it.

Moreover, the gas reservoir composition contained in these different bubbles is also different.

What I said before is only the initial average value.

Because there are too many bubbles like this, the original exploration team only roughly screened them for exploration.

At that time, four areas were selected for exploratory drilling, and a total of two or three *** were drilled and spot checks were conducted.

Then estimate the average value.

But even so, the estimated carbon dioxide levels vary.

The basic maximum content can reach 92%, and the minimum is only 60%.

The gas with the second highest content is methane, and the third highest is ethane. The content of these two gases can be as high as 40% and as low as 8%.

These two associated gases are both hydrocarbon gases, which are of great economic value.

Especially when it comes to refrigerants.

And even if not for industrial use, the two gases can also be used as fuel.

Although the calorific value is lower, it is also a clean energy with extremely low pollution.

In the past, the gas we used was actually mainly composed of methane and ethane.

And some bubbles contain high levels of helium and nitrogen.

The highest can even exceed one percent, which has a very high industrial value.

You must know that not only the price of helium is very high, but nitrogen is also very expensive.

As for the main produced carbon dioxide, in Xiao Feng's view, it can be used as a replacement agent for shale oil production and as a combustion accelerant for sludge residue.

This substance can also be made into gas fertilizer!

Yes, the opinion given by cloning experts is that it can be made into gas fertilizer.

After mixing a certain proportion of nitrogen and other chemical elements, it can be made into gas fertilizer.

Xiao Feng had never heard of this concept before. He knew about the cost of nitrogen, phosphorus and potassium.

But gas fertilizer? What is this stuff?

Cloning experts have given a reasonable explanation. In fact, green plants often need a lot of carbon dioxide gas when they perform photosynthesis.

Everyone knows this truth, but everyone has never known that it is necessary to carry out special carbon dioxide irrigation for plants?

In fact, this discovery was only discovered recently by foreign scientists.

Mainly from the buckle warm shed.

There are many countries abroad that are engaged in modern agriculture, such as Israel and Japan.

And their experts found that the vegetables grown in the greenhouses tasted very bad, and they were very small at first.

Later, after research, they found that the vegetables in these greenhouses did not taste good, and some even had no taste at all.

It is because of their imperfect photosynthesis during photosynthesis.

To know the main process of photosynthesis, in fact, plants absorb carbon dioxide in the air through the leaves, and then combine with the green leaves, and finally convert the carbon dioxide into sugar, or carbon-containing minerals unique to other plants.

And in the modern greenhouse, if it is the kind of soil greenhouse in H country, it is cultivated in soil, that is fine.

Because of the respiration of crops, the activities of microorganisms in the soil layer, and the decomposition of organic matter, a certain amount of carbon dioxide will be released.

However, Israel and the Japanese have done greenhouse cultivation, which is basically soilless cultivation.

Soilless cultivation means that the roots of the plants are soaked in a nutrient solution, and there is no soil underneath.

This way, no carbon dioxide is released from the soil layer.

As a result, there will be insufficient carbon dioxide in the greenhouse during the day when photosynthesis is required.

In the end, the efficiency of photosynthesis is greatly reduced, and the sugar synthesized by crops through photosynthesis is insufficient, so the taste is not good...
