It was drizzling and dark clouds were gathering.

On a small hillside in the north of Bandon Island.

In front of an unnamed tombstone built last year, Li Qingye placed a bouquet of white chrysanthemums on the stone platform and filled three wine glasses with green plum wine.

The dripping sound of rain was the only sound at the moment.

Feili, standing behind Li Qingye, held an umbrella dutifully.

Today is April 4, 2020, the Qingming Festival of the lunar calendar.

Li Qingye, who stood in front of the tombstone and was silent for more than ten minutes, put away the sadness in his eyes and turned around: "Go back!"

at the same time.

In a factory of Donghua Group in Pengcheng, all employees are working hard overtime.

Kong Zhaolin, who was entrusted with important tasks by Wu Heguang, was having a meeting in the factory office at this time.

"Gong Li, how is the condition of the equipment now?"

The skinny middle-aged man rubbed his temples: "It's almost done. The conversion system, synthesis system, second-turn system, and control system of the synthetic ammonia production line are all in place. The final inspection will be done today, and the factory test can be carried out tomorrow or the day after tomorrow. "

"Great, it's not easy!" Kong Zhaolin breathed a sigh of relief.

Although there are still nearly two months left before the delivery date, a complete synthetic ammonia production line needs to be disassembled, reassembled, transported, and assembled in the factory after parts production and customization, component assembly, complete machine assembly, and complete machine testing.

Although Kaile's requirement is to transport the equipment to the Luzon factory in June this year, Donghua Group will be given three months for installation and commissioning.

But this time is still too tight.

As the chief engineer, Li Xinyi is very busy these days because he is forced by this construction deadline.

At the same time, he was also very dissatisfied with Kong Zhaolin and Wu Heguang for setting such a tight deadline in order to compete for the contract.

Kong Zhaolin also saw Li Xinyi's fatigue and dissatisfaction, and quickly comforted him: "Thank you for your hard work, Mr. Li. I will ask the company to hold a celebration banquet for everyone later. The bonus will definitely be indispensable."

"Haha, thank you very much, Vice President Kong." Li Xinyi still knows some ways about the world.

After the two finished chatting about work, they went to the testing site to inspect.

This kind of equipment should have been installed in the factory, and then passed debugging and trial operation. If there are no problems, it can be delivered to the factory. If there are problems, the equipment manufacturer needs to solve the problems.

It's just that Kaile Company is in Luzon. If the previous plan is adopted, the construction time of the entire project will be at least doubled.

Therefore, Donghua Group can only choose to manufacture the whole unit first, test it at its own site, and then disassemble and transport it to the factory in Luzon for reassembly and debugging.

Kong Zhaolin and Li Xinyi inspected it and found that there were no problems.

"Gong Li, let's do a trial run tomorrow!"

Li Xinyi nodded: "Yes, after all, many problems cannot be seen without actual testing."

This is also the reason why Kong Zhaolin hurriedly prepared for the test, because time waits for no one. From Pengcheng Railway to Haizhou Port, and then from Haizhou Port to Manila by cargo ship, the whole journey takes about 20 to 25 days, which is almost a month removed.

It's April 4th now, and the time left for them is only one month.

Within this month, they must complete the trial operation, debugging, and solve possible problems, and then disassemble and package it. The time is obviously very tight.

Kong Zhaolin, worried that something might go wrong, even arranged for security guards to be stationed around the clock.

That night.

In a brightly lit testing field.

More than a dozen cockroaches entered the core components of the equipment from the corners and gaps one after another.

The goal of these little things is very clear, staring directly at the radiant section of a reformer. There are hundreds of reformer tubes in the radiant section.

The inside of the reformer tube is filled with a special catalyst, and the inside of the tube is mainly used for the reaction of hydrocarbons and water vapor.

The outside of the pipe is a heating furnace, and the operating temperature usually reaches 900 to 950 degrees Celsius. The pressure inside the pipe is about 4Mpa, and the operating conditions are relatively harsh.

After the cockroach got into the heating furnace, it began to attach to the surface of the conversion tube and released a stream of mucus. The mucus contained a special acid that could destroy the alloy lattice structure by absorbing the carbon in the alloy steel.

After more than five hours of corrosion, more than a dozen weak points with a diameter of about one centimeter appeared in the conversion tube.

The cockroaches who completed their mission quickly returned the same way.

The next day, morning.

Li Xinyi and Kong Zhaolin both came to the remote control room of the test site.

"let's start!"

"Yes, Gong Li."

Workers quickly injected raw materials into the machine and then started to energize and ventilate it.

People in the test site have been evacuated. After all, this kind of test is risky, and even Li Xinyi, who is full of confidence, does not dare to stay in the test site.

Anyway, now automation technology and detection technology can use remote control, so no one wants to stay in the test field.

"Pressure 1.5..."

"Pressure 2..."

"Start injecting..."

With the injection of water vapor and hydrocarbons, the natural gas burned fiercely in the heating furnace outside, causing the temperature and pressure inside the conversion tube to rise rapidly.

There was nothing unusual at first.

Until the 13th minute, under the torture of high temperature and high pressure, four of the weak points on the wall of the conversion tube cracked.

Pfft...

The high-temperature and high-pressure water vapor and hydrocarbon mixed gas are quickly ignited by the flame of the heating furnace.

boom……

The horrific explosion directly tore through the entire heating furnace and conversion furnace, and spread to the shell of the synthesis furnace not far away.

What was even more fatal was that the natural gas pipeline of the heating furnace broke.

"Damn it! Turn off the natural gas!" Li Xinyi shouted with a pale face.

The employees, who had just woken up from a dream, hurriedly closed the gas valve, feeding valve, and pulverized coal injection valve.

At the same time, the emergency system was activated and began to extinguish the flames.

But at this critical moment, Li Xinyi and Kong Zhaolin sat slumped with bloodless faces, not in the mood to care about putting out the fire.

"It's finished! We're finished!" Kong Zhaolin muttered to himself.

Li Xinyi also looked downcast.

If there are other minor problems, they can be fixed. The problem is that the entire conversion system is now scrapped, and other systems have also suffered varying degrees of damage. This kind of big problem cannot be solved in a week or two.

Not to mention remanufacturing, just investigating the cause of the accident is enough for them to be busy.

Half an hour later, the flames were extinguished and the damage could be initially estimated.

Looking at the reformer and heating furnace that were blown to pieces in front of him, Li Xinyi said with trembling lips: "Vice President Kong, this ammonia production line is abandoned."

"I...I..." Kong Zhaolin almost stopped his heartbeat: "Huhu...what should I do?"

"Vice President Kong, please inform the chairman as soon as possible!" another executive reminded.

Confused, Kong Zhaolin took out his cell phone but failed to make a call.

Obviously he doesn't know how to report now. Wu Heguang gave him this important task just to train him as his successor. Now he messed up the matter, which made Kong Zhaolin have no courage to tell Wu Heguang about it.

Others did not dare to make their own decisions. After all, this matter naturally had to be handled by the person with the highest position on site.

Kong Zhaolin took a deep breath and finally called Wu Heguang.

"Hello... Zhaolin? What's the matter?"

"Uncle!..."

When Wu Heguang on the other side of the phone heard this title, he immediately felt something was wrong. Kong Zhaolin usually rarely called him uncle on the phone or in formal occasions.

"What happened?"

"..."
