Not long after the Mexicans were frustrated, Yangzi Petroleum told them that Yangzi Petroleum wanted to buy their gas. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

For a while, the rain passed and the sky was clear, and the bitterness came sweetly, and there was such a good thing, where did the Mexicans have no reason not to agree.

To be honest, after reaching an agreement with the Americans, they didn't make any money, and the money they made to sell oil was not enough to even pay the interest on the loan to Yangzi Bank, because the Americans exploited them too hard, and Rockefeller was only willing to give them two cents a barrel of oil, and they were not allowed to bargain, because that's how Americans sell it in China, and if the Mexicans refuse to sell, Rockefeller still won't buy it, you must know that buying oil from Mexico is higher than the domestic freight in the United States.

Mexico sold all the 3 million barrels of oil it had accumulated in one go, and sold it for $60,000, which was almost crying, and I felt that this was even more ruthless than when the Americans controlled their oil resources.

Mexicans are very envious of the deal between Yangzi Oil Company and Rockefeller, which is 1 dollar a barrel, which is 50 times higher than the price Rockefeller gave them, if Yangzi Oil Company can also buy Mexican oil at this price, what money do they have to worry about, if the Americans have been controlling their oil transportation, then they will never make money.

After understanding this truth, Mexico gritted its teeth, borrowed another $5 million, purchased Chinese equipment, hired Chinese engineers, and made up its mind to build an oil pipeline to the west coast of Mexico, and at the same time build port facilities, so that Chinese oil tankers can directly load oil in their ports, without going through the hands of the Americans, and without the Rockefeller's oil pipelines.

How complicated can Mexico's narrow border be to build an oil pipeline, in less than a year, the Mexicans will be able to build the oil pipeline to the West Bank port of Acapulco, and then they will not have to be subject to Rockefeller, but there is one problem, they have not considered, that is, they have signed an agreement with Rockefeller, their oil exports are through Rockefeller's channel, and now they have to find their own way out, which is tantamount to tearing up the agreement.

But this kind of nationalist government will not take these things into account, and they only see that Rockefeller has taken a lot of profits from them, but they do not see that Rockefeller has also used his own political resources to get the US military to abandon the blockade of Mexico.

Yang Chao can't manage so much, his strange ship has already set off, this ship was originally a cargo ship with a displacement of 5,000 tons, but in the economic crisis, the cargo ship has no business, Yang Chao bought it from the Fujian Huay Kuan Steamship Company as scrap.

The ship is 80 meters long, 12 meters wide, has a draft of 6 meters, and has a standard displacement of less than 5000 tons.

This thing was transformed very strangely, the hull, back three large round balls, the three large round balls are hollow, the inner diameter of 7 meters, the outer diameter of 8 meters, because it is a hemisphere, so the internal volume of each sphere is only more than 700 cubic meters, and the sum of the three spheres is only about 2100 cubic meters.

The inner diameter is 7 meters and the outer diameter is 8 meters, which means that the wall thickness of these three spheres is as high as 1 meter, and it is even more terrifying if you know that they are all made of high-strength cannon steel.

But who let Yang Chao never build a natural gas ship, so he adopted the most secure design.

This natural gas ship is different from the famous LNG ship in later generations, he is not transporting liquefied natural gas, the most important thing in the transportation of liquefied natural gas is stability, the temperature must be controlled at minus 162 degrees, natural gas can remain liquid, this era obviously does not have such technology.

Therefore, Yang Chao uses another method of transportation - compressed natural gas, there are three types of oil and gas transportation in later generations, the most efficient is of course the liquefied natural gas ship, referred to as LNG ship, and there is a kind of liquefied petroleum gas, referred to as LPG, LNG ship needs extremely stable insulation equipment, this era does not have, LPG transports liquefied petroleum gas, the main component is propane, which is different from natural gas with methane, so it cannot be used to transport natural gas, and the last transportation equipment for transporting natural gas, referred to as CNGThe principle is to compress natural gas into a container, the same principle as the gas canister used by ordinary people at home.

However, the gas tank is liquefied petroleum gas, compressed natural gas CNG transportation, mainly land car transportation, the car is equipped with a cylindrical gas tank, this gas tank is half about 12 meters long, but the diameter is only about 600 mm, just like a missile, so it is often called a bomb truck.

This kind of compressed natural gas tank can generally safely withstand the pressure of less than 25 megapascals, which means that the natural gas can be compressed 250 times, and the liquefied natural gas directly liquefies the gas, and the volume is only reduced by more than 600 times, so the pressure alone can reach one-third of the transportation capacity of the high-tech ship such as the LNG ship, and the efficiency is still acceptable.

As for the feasibility, there is no need to worry, although this method has not yet been applied, but it does not mean that the technology is not mature enough, the French company Air Liquide is a specialist in the production of such gas tanks, and they built a factory in Shandong long before the first world, and are now the largest supplier of hydrogen and helium storage tanks to Zeppelin.

The hydrogen tanks they produce have a pressure of 25 megapascals, which makes no sense that they will explode if they are loaded with natural gas, and Yang Chao asked them to use the most advanced artillery steel, the latest type of running steel developed by Shandong Arsenal, the pressure of the cannon chamber can withstand 500 megapascals, and only 25 megapascals is just pediatrics.

Even so, Yang Chao did not agree to ship 25 megapascals of compressed natural gas, and only allowed them to ship 20 megapascals.

This time it was such a ship that went to Mexico, with a volume of 2,100 cubic meters, transported with 20 megapascals, which is equivalent to 200 times compression, and the gas that can be loaded at one time is 420,000 cubic meters.

The calorific value of 1 cubic meter of natural gas is about 1.2 kilograms of standard coal, and 420,000 cubic meters of natural gas sounds terrifying, but it is only a pitiful standard coal of more than 500 tons.

Across the Pacific Ocean, just to transport 500 tons of standard coal energy of natural gas, it is obviously not cost-effective, and the cost cannot be recovered in a hundred years. So it's not a normal transport, it's a test, a test of transoceanic gas transportation.

Yangzi Petroleum Company's second main business is about to develop into natural gas transportation.

A year earlier, the ship had made several trips to Nanyang, transporting Brunei's natural gas back to Shandong and storing it in a gas storage tank in Dongying, fueling an experimental gas turbine.

This voyage was made to collect data for transoceanic transportation to facilitate the transportation of natural gas by large ships in the future.

Yang Chao is not naïve enough to produce a large number of such natural gas ships, he is already building a natural gas giant ship.

Through the construction of this ship, China Morning Bed Company has obtained sufficient technical reserves, and the first natural gas ship officially started to be built, using a 50,000-ton ship type, which was directly converted from a giant oil tanker.

The length of the ship is 280 meters, the width is 70 meters, the draft is 10 meters, and the storage tank volume is 80,000 cubic meters, which is almost more than one-third of the hull volume, and there is still a big technical gap with the volume ratio of one-half of the LNG ship in later generations.

However, with a volume of 80,000 cubic meters, 16 million cubic meters of natural gas can be transported at a time, and this efficiency is more practical, equivalent to about 20,000 tons of standard coal, standard coal can have higher heat than raw coal, and 1 ton of standard coal is about 0.7 tons of standard coal, so if it is counted as raw coal, it is close to 30,000 tons, and the efficiency is already quite good.

And in this era, the application of natural gas has not yet been promoted, with 50,000 tons of cargo ships, transporting natural gas equivalent to 30,000 tons of coal, Yang Chao gave Mexicans the equivalent of 1,000 tons of coal, Mexicans are already very happy, after all, if the Chinese don't want it, they really don't know what to do with those natural gases, in addition, their gas field reserves are huge, can produce tens of millions of cubic meters per year, and the average daily output is 5,000 cubic meters, and this is only in the case of drilling a well, If 100 gas wells are drilled, it is not a problem to produce 100,000 cubic meters a day.

Although the price of oil in this era is very low, the price of a wellhead per ton of oil is only a dozen cents, which is more than half of the price of a ton of coal of twenty or thirty cents, so the use of oil has a natural advantage, and this price will continue until the 70s, Japan, which lacks resources, is supported by cheap oil energy in the Middle East, to complete industrialization, at that time, the Japanese even used oil for power generation, and their economy collapsed after the price of oil rose.

However, the price of natural gas is cheaper, the calorific value of a ton of oil is equivalent to two tons of coal, and the price of a ton of oil is equivalent to half of that of coal, which means that oil with the same calorific value is only a quarter or even less of the price of coal with the same calorific value, and what is the price of natural gas for Mexicans?

Yang Chao offered them 1,000 cubic meters of 1 US dollar, 1,000 cubic meters of natural gas is equivalent to the calorific value of 1 and a half tons of coal, equivalent to more than 6 barrels of oil, the price of natural gas is only one-tenth of that of coal, and there is no need to pay for domestic freight in Mexico, which is more than one-sixth of the price of 1 dollar a barrel of oil.

But because Yang Chao is the only customer, and if they can produce 100 million cubic meters of natural gas per year, it is 100,000 US dollars, then what about 100 billion cubic meters per year, then there is 100 million US dollars, according to the estimation of Yangzi Petroleum Company's technicians, Mexico's gas fields have the potential to produce 200 billion cubic meters per year, which is worth the investment.

And if the international natural gas market can be developed, the price will rise, just like oil, that is, it will rise to 1,000 cubic meters of 2 US dollars or even 3 US dollars, which is still cheaper than oil, you must know that Rockefeller's oil 1 barrel of 1 US dollar a ton is 7.3 US dollars, even if the price of 1,000 cubic meters rises to 3 US dollars, it is still only half of the oil, which is a very reasonable price increase space.

Yang Chao also promised Petroleos Mexicanos that if the international natural gas market is formed, he is willing to pay according to the international price, and if the international natural gas market is never developed, Yang Chao is also willing to pay them according to this guaranteed price.

So as long as a few more gas wells are opened, $100 million a year is not a dream, and when Mexicans see Chinese gas ships, they are as happy as they see Jinshan sailing towards them, and in the end there are 10,000 people on the dock watching this strange ship.

But what about the Americans, will they be happy? (To be continued.) )
