In late November, the first draft of the preliminary design of the FG project was completed, and on Monday, November 23, a preliminary design review meeting was held in the conference room on the second floor of the design institute.

Geng Zhiyuan sat next to Wang Ping, opposite more than 20 employees of the Chemical Research Institute. Wang Ping whispered: "The back row is full of doctors and masters from famous universities, and their education is much higher than ours. ”

The requirements for academic qualifications of the chemical design institute are not high, and in addition to the bachelor's degree and junior college of formal colleges and universities, there are also a considerable number of employees with technical secondary school and correspondence degrees, which is a big difference in academic qualifications compared with the research institute.

The research institute and the chemical research institute are the same company, so the review meeting is actually the research institute to review the preliminary design products delivered by the design institute.

Mr. Yang, the project leader of the research institute, and the heads of the main projects took turns to speak, and the methanol distillation section was an auxiliary main project, so it fell last. The research institute was in charge of reviewing methanol distillation, and he didn't see much of a problem, only a few clerical errors.

Seeing that the next section was about to be carried out, Cheng Jianguo bent over to Mr. Yang and whispered a few words. He found the methanol distillation equipment table and the equipment diagram, looked at it twice, raised his notebook and asked Shen Debang: "Manager Shen, how can you change the material of the methanol distillation equipment without authorization? How much will it cost us to change to such an expensive titanium material?"

Shen Debang was stunned: "Methanol distillation?"

Seeing this, Geng Zhiyuan's heart sank, and he said secretly: "It's not good! This thing is going to be bad!"

Shen Debang turned to Wang Ping and asked, "Who did the methanol distillation?"

Without waiting for Wang Ping to answer, Geng Zhiyuan said calmly: "Shen Gong, I did the methanol distillation. ”

Shen Debang saw that it was Geng Zhiyuan, and frowned: "You changed the material?"

"Yes, because of chloride corrosion, the equipment professional recommends changing to titanium. Geng Zhiyuan replied truthfully.

Cheng Jianguo sneered on the side: "How is it possible? What materials do you propose, what materials do we use, how can we take the initiative to change them?"

"Xiao Geng, what do you say, what's going on?" Shen Debang became serious and asked sharply.

Geng Zhiyuan could only confess: "My first version was proposed according to the 304 recommended by the research institute, and after sending it to the equipment, Zhu Lei said that 304 could not be used for chloride ion corrosion, and it was best to replace it with titanium." ”

"Cheng Gong, call Zhu Lei over. "The preliminary design review meeting is going well, and seeing that it is at the end, it suddenly comes out like this, which makes Shen Debang very passive. He was quite annoyed, and Geng Zhiyuan was also very worried.

Zhu Lei did not shirk after being called to the conference room: "It was I who proposed to change the material, because of the presence of chloride ions, which corrodes 304." ”

Shen Debang pondered for a while, and said to Cheng Jianguo: "Cheng Gong, what is your opinion?"

Cheng Jianguo said disdainfully: "If there are chloride ions, titanium will be used? ”

Seeing that he was confident, Mr. Yang politely asked: "Cheng Gong, you mean that we can use 304 for this piece, and we don't have to worry about chloride ion corrosion, right?"

Cheng Jianguo said proudly: "Chloride ions can produce porosity and stress corrosion on austenitic stainless steel, 304 is slightly worse, it can be changed to 316, and the solid solution treatment is carried out after the equipment is made, which can minimize the trouble caused by chloride ions." ”

Geng Zhiyuan and Zhu Lei looked at each other, and he asked quietly, "Is what Cheng Gong said right?"

Zhu Lei pouted and said: "He is the person in charge of the profession, what does he say, let's do it." ”

Geng Zhiyuan saw that he was not convinced, and said uncomfortably: "Can 316 solid solution resist chloride ion corrosion?"

"It can be mitigated, but it can't be avoided entirely. Zhu Lei said unwillingly: "I still think that titanium is the most suitable and safest under this condition." ”

After listening to Cheng Jianguo's suggestion, Mr. Yang admired: "Jiang is still old and spicy, and young people lack some heat after all." Cheng Gong's suggestion is good, although 316 is more expensive, it is much cheaper than titanium. Manager Shen, if you want to change the materials in the future, you have to talk to us, after all, we spent our own money to build this project. ”

"It's easy to say, it's easy to say......" Shen Debang forced a smile, turned his head and whispered to Wang Pingdao: "Write this in the meeting minutes." ”

The review meeting was finally successfully concluded, Shen Debang accompanied Mr. Yang to the office of Dean Mu Fanyu, and after greetings, Mu Fanyu asked: "Mr. Yang, the meeting went smoothly, right?"

Mr. Yang nodded and said, "It's going well." Dean Mu, your design institute is really a hidden dragon and a crouching tiger!"

was praised by the partner in person, Mu Fanyu's face was very bright, and he said modestly: "Mr. Yang, I have won the award!"

Seeing that Mu Fanyu had misunderstood what he meant, Mr. Yang further clarified: "If it weren't for your Cheng Gong to control the pass this time, we would have to spend money in vain." ”

"Cheng Gong?" Mu Fanyu glanced at Shen Debang: "Shen Gong, what's going on?"

As the saying goes, ugliness should not be publicized, even if Geng Zhiyuan and Zhu Lei did not think things through, Cheng Jianguo should not directly disclose them to the research institute without ventilating, which put the project team in an extremely passive situation. Cheng Jianguo's move can be said to be ignorant of the inside and outside, and Shen Debang has a stomach for him.

Shen Debang said with a smile: "There is a section where the selection of materials is not too suitable, and the two young people in our hospital saw the problem, and Cheng Jianguo gave a better solution." ”

"Oh, that's right. Mu Fanyu has been the dean for many years, and sensitively heard the meaning of Shen Debang's words, and said with a smile: "The research institute is more solid than us in theory, and we have a little more experience in practice. ”

As soon as the matter was revealed, the guests and hosts had a very happy conversation. After the meeting, the minutes of the meeting signed by both parties clearly stated that in consideration of chloride ion corrosion, at the request of the Institute, the material of the methanol distillation equipment was changed from 304 to 316, and the solid solution treatment was required after the equipment was processed.

Although the review meeting was disgraced, the project still had to be carried out, and the methanol distillation section was not modified much, and Geng Zhiyuan took half a day to complete the revision of the preliminary design.

Shen Debang was worried that Geng Zhiyuan was under pressure, so he specially found him and comforted: "Xiao Geng, I just started to do design, and there is nothing wrong with it." And you can find problems and take the initiative to solve them, that's progress. Do your job well, don't be burdened. ”

As the leader of the project team, the design manager should not only be outstanding in technology, but also be responsible for building a good relationship with the outside world, solving contradictions internally, straightening out the relationship, and taking responsibility for problems encountered.

Geng Zhiyuan was very grateful for Shen Debang's care and suggested: "Shen Gong, I think Cheng Gong did something wrong this time. ”

The young man could see that Cheng Jianguo was doing something inauthentic this time, and Shen Debang was deeply surprised and said, "What's wrong?"

"After he finds a problem, he should communicate with us in a timely manner, or report to you, internal problems are solved internally, why bother to tell outsiders about our shortcomings? After all, there is a difference between inside and outside, doesn't this put our project team in a passive situation?" Geng Zhiyuan's words impressed Shen Debang, this kid is good, he knows the importance of the inside and outside, and he is much better than the old comrades who are a little confused and only think about their own appearance.

"I'll talk to him about this, don't go around talking about it, understand?" Shen Debang admonished.

"Well, I understand. Shen Debang can listen to his own thoughts, and Geng Zhiyuan is also very pleased.

In the blink of an eye, at the beginning of December, the design institute signed a big contract: the Haizhou 1830 project (note). This is the first time that the Donghai Provincial Chemical Design Institute designed 1830, and compared with other brother provincial institutes, the Donghai Institute lags behind a lot in technological progress.

In order to do a good job in the 1830 project undertaken for the first time, the design institute specially selected Lin Yin as the design manager of the 180,000-ton synthetic ammonia plant of the project, Xia Su as the design manager of the 300,000-ton urea plant, and Yue Weiben, vice president, as the general coordinator of the project. And from each room to draw capable forces to form a project team.

Geng Zhiyuan, as a student of Xia Su, was selected into the urea project team and became the designer of the main urea device.

Compared with the urea plant of three or four main items, the synthetic ammonia plant can be described as a huge lineup, only the main items have gas production, blowing air recovery, desulfurization, compression, transformation, decomposition, fine decomposition, synthesis and so on 14 or 5, which does not include the main projects of public works such as circulating water stations, fire water stations, substations, switch stations, and DCS control rooms.

There are only more than 30 people in the craft room of the Provincial Design Institute, and it is still not enough for an 1830 project to use almost all the people who can use it, so Geng Zhiyuan has to be arranged in the synthesis section, mainly responsible for helping Lin Yin complete the piping drawing.

The first time he came into contact with the synthetic ammonia process, Geng Zhiyuan specially consulted Lin Yin and asked for a set of "Process Technology and Design Manual for Small Ammonia Plant" from her, and took the time to study it carefully.

On the morning of Saturday, December 5, Geng Zhiyuan was working overtime in the office to study synthetic ammonia, and Lu Wenwu suddenly called the office: "Brother Geng, I have found you!" Lu Wenwu said anxiously on the phone: "You hurry up to the emergency center of the Second Provincial Hospital, my third sister committed suicide by cutting her wrists." ”

"What!?" Geng Zhiyuan was startled: "Your sister committed suicide by cutting her wrists?"

"It's been rescued, and a lot of blood has been shed, I can't persuade her, so please persuade her. Lu Wenwu begged: "Brother Geng, I don't know anyone else in the provincial capital except for you, so I can only ask you for help." Please......"

"Don't say it, you take care of your sister, I'll go over right away!" Geng Zhiyuan hurriedly put on his coat, put on his hat and went out.

In the ward of the emergency center, Lu Yi was lying on the hospital bed with a pale face, closing her eyes and silently. When Geng Zhiyuan hurriedly walked into the ward, Lu Wenwu and another girl who were guarding the bedside hurriedly stood up.

"What happened?" Geng Zhiyuan glanced at Lu Yi, who was dead on the bed, and asked in a low voice.

Lu Wenwu shook his head in ignorance, pointed to the girl beside him and said, "Sister Li knows what's going on. ”

The girl glanced at Geng Zhiyuan and said, "You are Geng Zhiyuan, right?" I am Li Jie, Lu Yi's roommate. ”

"Hello Li Jie. Geng Zhiyuan nodded at her and said, "Why can't Lu Yi think about it?"

"This ......" Li Jie glanced at Lu Wenwu, pointed to the door and said, "Let's go out and say okay?"

Geng Zhiyuan saw that her face was difficult, and he knew that some words were inconvenient for Lu Wenwu to hear, so he followed her out of the ward to find a corner where no one was.
