Yu Hua smiled: "Yes, in theory, once thirty tons of sulfur are produced and sold, the total value of the sulfuric acid can recover all the R&D investment in the Yu's Seven Towers project."

"27,000 silver dollars... It's really unimaginable." The elegant man was shocked. He turned to look at Yu's Seven Pagodas and once again felt the extraordinary charm and terrifying productivity brought by science.

fear.

Really scary.

Is this the charm of science and technology?

The total investment in technology research and development was 15,000 silver dollars, and the total value of the trial production of 90 tons of sulfuric acid was 27,000 silver dollars. This was an incredible return even he heard. If the news spread, it would be enough to drive capitalists across the country crazy.

If nothing goes wrong, the sulfuric acid products produced by Yu's Seven Pagodas will become one of the important economic sources for the base area. According to the initial planned annual output of 24,000 tons, the annual economic benefit will be as high as 7.2 million silver dollars, not counting the outbreak of war.

There is a high probability of price increases in the future.

If the price of sulfuric acid increases by 50 silver dollars per ton, the annual economic benefit will increase by 1.2 million silver dollars.

The importance of money is self-evident.

And all of this was brought about by Yu Hua.

The first experiment continued. Next, Yu Hua ordered to enter full-load production mode, and Yu's Seven Towers entered the maximum industrial production state. The pre-processed industrial sulfur continuously entered the silo under the action of the conveyor belt, and the valuable high-purity concentration

The sulfuric acid flows out from the end of the device and is stored in the tank.

A storage tank with a volume of 50 cubic meters can store up to 92 tons of sulfuric acid, which just meets production needs.

The sky is getting dark and turning into night. The prototype of Yu's Seven Towers has been in stable production for more than 3 hours. The current flow rate per hour is about 0.87 tons, and the designed flow rate per hour is 0.916 tons. The ratio of actual output to design indicators has reached 94.9%, which is in line with

First trial production requirements.

However, it is not yet time to draw a conclusion.

The actual output needs to meet the standard, and the unit operation needs to be stable and reliable.

Late at night, each production team stood ready and stood firm. They deeply understood how important their work was, and they all tried their best without any cheating.

Yu Hua and all members of the design team also stayed at the experimental site and did not leave even half a step.

Industrial waste gas, which symbolizes high pollution, pours into the night sky, polluting the surrounding environment. Industrial wastewater enters the reservoir along with Baiyangdian, polluting the water quality and poisoning fish and shrimp. High-purity sulfuric acid, which symbolizes money and hope, continues to flow into the lake.

Storage tank.

This is the best of times and the worst of times.

On the 12th hour of the first experimental trial production, at 4 a.m., Yu's seven-tower prototype ran at full load for 11 hours. The condition was reliable, and all pressure gauges and parameters were normal. Each production team was familiar with the entire production model, and their proficiency improved.

This increases production efficiency. The current flow rate per hour is about 0.89 tons, and the actual production rate rises to 97.1%, exceeding the indicator line.

On the 19th day of the Yu's Seven Towers research and development project, the first experimental trial production process is halfway through.

"Huh..." Lin Wan held the notebook in her left hand and recorded the hourly traffic data in detail with her right hand. After finishing her work, she swayed slightly and felt dizzy, so she quickly supported the table with her hands.

"Are you okay? Jin Yu." Seeing this, Yu Hua took a step forward and asked.

"It's okay, I'm just a little dizzy and my eyelids are fighting." Lin Wan shook her head and said softly with a tired tone.

Not only Lin Wan was tired, but also Fang Yu and Zhou Yuan, members of the design team, all looked tired.

"It's been twenty-three hours since five o'clock yesterday morning. Why don't you go get some sleep first and I'll call you later." Yu Hua said softly.

"No, I can still hold on. This is the most important moment for Yu's Seven Pagodas. I can't sleep." Lin Wan shook her head and said.

Fang Yu and Zhou Yuan nodded in succession.

"Okay, there are still twelve hours left. We have already seen the dawn of victory. Come on." Sensing the attitude of the three people, Yu Hua stopped trying to dissuade him and encouraged him.

Whether from a physical or psychological perspective, everyone has reached their limit and is on the verge of collapse.

For so many days, everyone barely had a good night's sleep. They basically only slept for four or five hours before starting a new round of work. Fang Yu even had a menstrual period on the way, and endured the discomfort in the experimental site.

Running around, even if Yu Hua dissuades him, it is useless.

And all this is just for success.

Twelve hours left, victory is already in front of us.

"Come on." The three of them looked at each other with determination in their eyes and nodded in unison.

…

Time keeps passing like quicksand, one hour after another, and in a blink of an eye, at 3:30 pm on the nineteenth day, twenty-three hours and thirty minutes have passed since the start of trial production, and there are still only thirty minutes left before the actual daily production data is collected.

minute.

The afternoon sun is so hot and poisonous that it seems to be roasting people to death.

In the experimental site, all project participants were present. The elegant man and Liu Wei stood on the podium, with pairs of eyes containing different colors, all placed on the Yu's seven-tower prototype machine that was steadily producing sulfuric acid.

As the team leader, Yu Hua stood at the front, with three members of the design team behind him.

"Collect flow parameters." As the minute hand of the watch accurately returned to zero and the hour hand pointed to four o'clock, Yu Hua's mind remained clear. The golden mathematical symbols released a cold meaning to relieve brain fatigue. He took a deep breath and issued a new command.

The dispatcher immediately waved the flag and conveyed the order, and the production team at the other end immediately executed it, collected a new round of flow meter data, and sent it to the command podium.

This is the last traffic data, recording the traffic data for the 24th hour.

Yu Hua took over the newly collected data, then added the hourly flow data of the past twenty-three hours for calculation, and obtained the twenty-four-hour sulfuric acid production and production trend, and then made it into a simple data visualization

sketch.

Data visualization sketches allow people to understand the entire data information more intuitively.

In the field, it is quiet.

Everyone waited silently, feeling extremely nervous and not daring to breathe.

Qualified or unqualified?

Three minutes later, Yu Hua picked up a piece of paper recording the 24-hour sulfuric acid production data, turned around, and faced everyone.

"The first experimental trial production data of Yu's seven-tower prototype machine are as follows: the actual output of sulfuric acid in 24 hours: 21.12 tons, the output per hour is 0.88 tons, the ratio to the design output is 96%, and it meets the requirements of the trial production indicators."

"Comrades, we succeeded!"

With his words full of solemnity, Yu Hua announced the final results of the trial production and the actual output to everyone on site.

Trial production passed and actual output qualified.

boom!

In an instant, the entire experimental site fell into a commotion after a brief period of calm. Everyone was extremely excited, and the emotions that had been stored in their hearts for a long time seemed to burst out like a dam. They did it.

"Okay, okay, great!"

The elegant man standing at the front raised his hands, applauded quickly, and applauded Yu Hua who was standing in front of the podium. He said several good things one after another: "This is a victory. A victory in the technical field is no less important.

To annihilate one enemy division, no, it should be an army!"

Success!

It took nineteen days, the culmination of Yu Hua's hard work and more than 200 people's sweat - the Yu's Seven Towers project was officially declared a success.

With Yu's Seven Towers technology, the base areas with weak economic foundation and backward development level will be injected with a shot in the arm.

In terms of economic benefits alone, the sulfuric acid industry based on Yu's Seven Towers technology can generate millions or even tens of millions of silver dollars in revenue every year, not to mention the important role of sulfuric acid in the military industry and steel smelting fields.

When they heard the final results announced by Yu Hua, Lin Wan and the other two people, who had been holding on for more than thirty hours, all showed comfortable smiles on their faces and applauded warmly.

The applause was as warm as the tide, and everyone gave heartfelt applause to the experimental results and Yu Hua, the founder of Yu's Seven Pagodas.

Yu Hua smiled and accepted the applause from these pioneers calmly. He was qualified to accept this applause because he was the one who brought the new seven-tower device that only appeared in the 1950s to the Marco Polo Bridge in 1937.

On the eve of the incident.

Be calm and accept it!

"Bang!" Not far away, the entourage of the elegant man raised the camera in his hand, found the right angle, and pressed the shutter.

The picture is frozen. In the black and white photo, the blue sky and the experimental field are used as the background. Yu Hua is standing on the podium with a smile on his face. In front of him are the elegant men, Liu Wei, members of the design team and the project who are applauding warmly.
