After 14 hours of hydrogenation reaction, the test results showed that the conversion rate of raw materials reached 98%, the selectivity of the reduction product was 100%, and the appearance of the hydrogenation reaction solution was a colorless and transparent liquid, which was expected by Fang Hanmin.

"The results are so ideal!" Guo Pengxi is colorful.

"In addition to the ultra-high selectivity and conversion rate, the appearance color is also ideal, which lays a very good foundation for subsequent separation and purification." Xu Hui is mainly responsible for the crystallization separation of the product, and he is very concerned about the color of the hydrogenation reaction solution.

"Yes, as long as the color is controlled in this step, the separation and purification in the future will save a lot of trouble. However, this is only the result of the first test drive, and it does not tell the whole story. Fang Hanmin has always kept a clear head, and he will never be complacent about a certain result.

Next, Fang Hanmin's team carried out three trial productions on the No. 0602 equipment, and the results were similar each time, and the gap between the two results did not exceed 0.5%.

Fang Hanmin decided to suspend the trial production, he wrote a report based on the results of the three trials, and submitted it directly to Lao Yuan, "Director Yuan, this is the summary report of our three trial productions, please take a look." ”

"Results so soon?" Lao Yuan flipped through the report and motioned for Fang Hanmin to sit down opposite, he crossed the trial production process in the report and went straight to the data summary table, "The result is very good!" If this indicator can be reached in actual production, no domestic paracetamol API manufacturer will be able to compete with Red Star Pharmaceutical Factory. ”

"The factory director is assured that even if the hydrogenation reduction process is fully adopted in the second workshop in the next step, the economic and technical indicators will not be lower than the results obtained in the trial production." Fang Hanmin said very confidently.

Lao Yuan looked at Fang Hanmin and smiled, "Why are you so confident?" ”

"Director Yuan, we have carried out three trial productions, and you can see the results of each time, and the biggest difference is not more than 0.5 percent, which shows that the process conditions are very stable, and it is not an immature technology with big ups and downs."

Director Yuan nodded in agreement, and said meaningfully: "The results of the three times are very close, indicating that the process technology is mature." But Hanmin, like everyone else, I also have curiosity, such an advanced technology, from the laboratory to the industrial trial production, you only took about half a year to develop, I want to know is, how did you do it? Coupled with the work you have done before, how did you, a high school graduate, master so much modern pharmaceutical technology? ”

All other questions are easy to answer, but this one, Fang Hanmin can't reveal his identity as a traverser no matter what, so he has to use the self-taught reason to prevaricate.

But Director Yuan, as the leader of a large state-owned enterprise and a veteran college student, has seen a lot of the world, and he doesn't believe Fang Hanmin's nonsense at all, "Self-taught? Ha ha! Let's close the door, there are no outsiders here, Hanmin, do you think I can believe what you say? ”

"This ......," Fang Hanmin didn't expect Lao Yuan to speak like this, he could only continue to prevaricate, "Director Yuan, there are not no self-taught people in society!" ”

"I don't deny that there are self-taught people, and if you only know about general pharmaceutical technology, or pure mathematical knowledge, I believe you are self-taught. But these process technologies you take out are not only advanced technologies that have not been seen by those senior engineers in our factory, but also require advanced theoretical foundation and rich practical experience to understand, I think it is impossible for a self-learner to master these advanced knowledge. ”

Lao Yuan's suspicion was logically irrefutable, but Fang Hanmin couldn't tell the truth, he blushed and said: "Director Yuan, I was a top student in Guichun No. 2 Middle School in high school, but it was just because of an accident before the college entrance examination that affected my college entrance examination results, otherwise, I would have been admitted to a key university." Not to mention that in front of the top leaders of the whole factory, even in front of his colleagues, Fang Hanmin never mentioned the previous history without shame.

Seeing that Fang Hanmin seemed to have unspeakable inconvenience, Director Yuan smiled, "Hanmin, I won't tell you, I've seen your archives and know a little about your history, but ......, forget it, my curiosity ends here, let's not talk about this issue." ”

The trial production organized by Fang Hanmin's team has achieved ideal results, and Deputy Director Wang can no longer find a reason to object, according to the plan, the in-depth technical transformation of the second workshop will officially kick off. The factory decided to set up a technical transformation headquarters, with Fang Hanmin as the commander-in-chief, and the deputy commander-in-chief including the two leaders of the second workshop and the department head responsible for the water and electricity supply of the whole plant.

During the technical transformation, in order to minimize the impact on the normal production of the second workshop, after obtaining the consent of the production and sales departments of the Red Star Pharmaceutical Factory and the workshop leaders, Fang Hanmin decided to divide the technical transformation into two phases, and each phase of the project only carried out technical transformation of one API production line.

Because each production line has hundreds of equipment, in accordance with the process requirements of hydrogenation reduction technology, the vast majority of equipment and the pipelines of the old process must be adjusted or reinstalled, some time ago when preparing for trial production, because there is very little equipment, the adjustment and installation of equipment and pipelines are completed by the operators of Fang Hanmin's team, and the next step is to face hundreds of sets of equipment for the entire production line, because its workload is too large, Fang Hanmin asked the factory to outsource the construction project.

The request was quickly approved by the plant leadership, and Deputy Director Zhou, who was in charge of infrastructure construction, was instructed to contact the construction unit.

Two or three months ago, because of the construction of the pilot site and test equipment, Fang Hanmin had dealt with Deputy Director Zhou, and now although he is not very familiar with him, he at least knows him.

After receiving a call from Deputy Director Zhou, Fang Hanmin hurried to his office, and after entering the door, he saw a middle-aged person wearing work clothes from a foreign unit present, and Lao Zhou introduced Fang Hanmin and the guest to each other, and it turned out that the middle-aged guest was the person in charge of the construction unit contacted by Lao Zhou. After a few polite words, Lao Zhou asked Fang Hanmin to communicate directly with Manager Liang of the construction unit, "If the two sides have any requirements, you can talk directly." ”

Because Lao Zhou is only responsible for contacting the construction unit, and doesn't care about other things, Fang Hanmin thinks it's okay, "In order not to disturb Director Zhou's work, let's go to my office to talk." ”

In Fang Hanmin's office, he handed over the construction drawings to Manager Liang, and put forward twenty or thirty construction requirements, acceptance standards and construction deadlines, and the two sides made a memorandum.

Fang Hanmin decided to let Jiao Tiehui be the representative of Party A to supervise the construction quality.

According to the agreement between the two parties, early the next morning, the people of Shuangling City Installation Company will be stationed in the second workshop of Hongxing Pharmaceutical Factory, and they will partially dismantle and reinstall the first production line of the workshop according to the drawings and construction requirements provided by Party A.

From the first day that Party B's construction team entered the second workshop, Jiao Tiehui squatted on the construction site all day long, even if the dismantled pipeline parts, he also asked to be classified and properly kept. I have to say that Fang Hanmin asked Jiao Tiehui to be the representative of Party A, which can be regarded as choosing the right person.

At the beginning stage, Party B's construction staff praised this Master Jiao for his strong sense of responsibility, but after a while, they found out that this guy was too picky! The construction requirements are almost to the point of being harsh.

Entering the equipment pipeline installation stage, this morning, Jiao Tiehui checked the position of several equipment, he came to the pipeline configuration site with a tape measure and a level, and used the level to detect several pipelines that had been assembled, and suddenly turned around and shouted loudly into the distance: "Master Ma, you come here!" ”

"Master Jiao, is there anything wrong with you?" The middle-aged man who was called Master Ma by Jiao Tiehui was the on-site technical representative of Party B.

"Come here, you'll know."

Lao Ma came to Jiao Tiehui, "What is the matter in such a hurry?" ”

Jiao Tiehui pointed to the several sections of pipelines in front of him and asked solemnly: "Master Ma, who did this work yesterday afternoon?" ”

"What's going on?" The old horse walked over and looked left and right, "Master Jiao, you did a good job, I didn't see anything wrong!" ”

Jiao Tiehui took two steps forward and handed the level in his hand to Lao Ma, "Measure it yourself and see what the inclination angle of those sections of pipelines is." ”

Lao Ma took the level, compared it on several sections of the pipeline, and then looked up at Jiao Tiehui, "It's basically about three degrees." ”

Jiao Tiehui nodded, "It's about the same, the result of my measurement is also about three degrees." ”

"Why, isn't this angle good?"

"Master Ma, it's not up to you and me to decide whether it's okay or not, you take out the drawings and see what is required on them?"

Lao Ma took out a stack of drawings from a toolbox, found a related one, and looked at it carefully, "Master Jiao, the inclination angle of the pipe marked on the drawing is five degrees. ”

"That's right, but you measured it yourself just now, and this inclination angle is only three degrees, and the construction quality is obviously unqualified!"

Lao Ma was a little confused, "The construction quality is not qualified, so what should I do?" ”

"Do you need to say it? According to the provisions of the construction agreement, the quality is unqualified and can only be reworked! Jiao Tiehui said without hesitation.

"Rework? Master Jiao, isn't it just that the inclination angle of the pipeline is two degrees different? It shouldn't delay the use, right? What a job! ”

"Don't delay using? That's what you said! How do you know without delay? If the three degrees and five degrees are the same, the designer simply asks for horizontal installation! Let me tell you, the material passing through these pipelines is not tap water, but a liquid with a certain viscosity, and the technical department requires designers to consider the viscosity of the material when arranging the pipelines according to the characteristics of the materials. The pipeline you installed only has a three-degree inclination, which does not meet the design requirements, and we will not be able to use it in the future, can we do it without rework? ”

"Master Jiao, don't look at a few simple pipelines, as long as it is reworked, it will take two or three days, how to ensure the construction period?" The old horse was very embarrassed.

"Master Ma, this is not a question I should answer, if you are afraid of delaying the construction period, you will not have anything to do with the quality during the construction process? You can't make the installed equipment unusable in order to ensure your construction period, right? ”

These words choked Lao Ma for a while, but as a representative of Party B, Lao Ma, the old fritter, seems to be very experienced in dealing with this kind of thing, "Master Jiao, in addition to rework, can we solve the problem in other ways?" ”

"Other ways, do you have any other ways?" Jiao Tiehui looked at each other suspiciously.

The old man pulled Jiao Tiehui's hand, "Let's go, let's go over there and talk." ”

The two came to an open space, and seeing that there was no one around, Lao Ma took out a box of cigarettes from his pocket, took out one and handed it to Jiao Tiehui, "Master Jiao, please smoke." ”

Jiao Tiehui not only didn't stretch out his hand to pick it up, but also asked, "Master Ma, we've been in contact for many days, right?" When did you see me smoking? ”

"Oh, you see I forgot, yes, you don't smoke." The old horse said embarrassedly.

Jiao Tiehui didn't care about this, "Don't you have other solutions?" Let's talk about it! ”
