After fourteen hours of hydrogenation reaction, the test results showed that the raw material conversion rate reached 98%, the selectivity of the reduction product was 100%, and the appearance of the hydrogenation reaction liquid was a colorless and transparent liquid. This result was Fang Hanmin expected it.
"The result is so ideal!" Guo Peng beamed with joy.
"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 and 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, a lot of trouble will be saved in subsequent separation and purification. However, this is only the result of the first test run, and it cannot explain all the problems." Fang Hanmin always remained sober. Mind, he will never be complacent about a certain result.
Next, Fang Hanmin's team carried out three trial productions on equipment No. 0602. The results each time were similar, and the maximum difference between the two results did not exceed 0.5%.
Fang Hanmin decided to suspend trial production. He wrote a report based on the three results and submitted it directly to Lao Yuan, "Director Yuan, this is the summary report of our three trial productions. Please read it."
"The results are available so soon?" Lao Yuan was flipping through the report and motioning for Fang Hanmin to sit down opposite him. He skipped the trial production process in the report and went straight to the data summary table, "The results are very good! If in actual production If we can reach this target, no domestic paracetamol API manufacturer will be able to compete with Red Star Pharmaceutical Factory."
"The factory director can rest 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 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. Look at the results each time. The biggest difference is no more than 0.5%. This shows that the process conditions are very stable and it is not an immature technology with ups and downs."
Factory 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 am also curious. Such advanced technology can go from small laboratory tests to industrial trials. Production, you developed it in only about half a year. What I want to know is, how did you do it? In addition to the work you did before, how did you, a high school graduate, master so many modern pharmaceutical technologies? ?”
All other questions were easy to answer, but for this question, Fang Hanmin could not reveal his identity as a time traveler no matter what, so he had to use the excuses he had learned on his own.
But Director Yuan, as the head of a large state-owned enterprise and a veteran college student, has seen a lot of big things in the world. He doesn't believe Fang Hanmin's nonsense at all, "Self-taught? Haha! 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 Old Yuan to speak like this, so he could only continue to prevaricate, "Director Yuan, there are not many self-taught people in the society!"
"I don't deny that there are people who are self-taught. If all you know is general pharmaceutical technology or pure mathematics and physics, I believe you are self-taught. But the process technologies you have come up with are not only those of the advanced people in our factory. It is advanced technology that no engineer has ever seen, and it requires a profound theoretical foundation and rich practical experience to understand. I think it is impossible for a self-taught person to master this advanced knowledge."
Lao Yuan's suspicion was logically irrefutable, but Fang Hanmin could not 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 only because of an accident before the college entrance examination. , It affected my college entrance examination results, otherwise, I would have been admitted to a key university." Not to mention in front of the top leaders of the whole factory, even in front of his colleagues, Fang Hanmin never mentioned the past history without shame.
Seeing that Fang Hanmin seemed to be in unspeakable inconvenience, Director Yuan smiled and said, "Hanmin, to be honest, I have read your file and know a little bit 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 achieved ideal results. Deputy Factory Director Wang could no longer find any reason to object. According to the plan, the in-depth technical transformation of the second workshop will officially begin. The factory decided to set up a technical transformation headquarters, with Fang Hanmin as the general commander. The deputy general commanders included the two leaders of the second workshop and the head of the department responsible for the water and electricity supply of the entire factory.
During the technical transformation, in order to minimize the impact on the normal production of the second workshop, Fang Hanmin decided to divide the technical transformation into two phases after obtaining the consent of the production and sales department and workshop leaders of Hongxing Pharmaceutical Factory. Each phase of the project would only focus on An API production line undergoes technical transformation.
Because each production line has hundreds of pieces of equipment, according to the process requirements of hydrogenation reduction technology, most of the equipment and pipelines of the old process must be adjusted or reinstalled. When we were preparing for trial production some time ago, because there were very few equipment, The adjustment and installation of equipment and pipelines were completed by operators from Fang Hanmin's team. The next step was to face hundreds of sets of equipment for the entire production line. Because the workload was too large, Fang Hanmin asked the factory to outsource the construction project.
This request was quickly approved by the factory leaders, and Deputy Director Zhou, who was in charge of infrastructure construction, was tasked with contacting the construction unit.
Two or three months ago, Fang Hanmin had dealt with Deputy Director Zhou because of the construction of the pilot site and test equipment. Although he was not very familiar with him now, at least he knew him.
After receiving a call from Deputy Factory Director Zhou, Fang Hanmin hurried to his office. After entering, he saw a middle-aged man wearing work clothes from another unit. General Zhou introduced Fang Hanmin to the guest. 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 both parties have any requirements, you can discuss them directly."
Because Lao Zhou is only responsible for contacting the construction unit and does not care about other matters, Fang Hanmin thinks this is fine, "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. The two parties 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, personnel from Shuangling City Installation Company entered the second workshop of Hongxing Pharmaceutical Factory. They will partially dismantle the first production line of the workshop based on the drawings and construction requirements provided by Party A. , and reinstall.
From the first day when Party B's construction team entered the second workshop, Jiao Tiehui squatted at the construction site all day long. Even the disassembled pipe parts were required to be sorted into categories and properly kept. Once he found that they were littered, he would immediately ask the other construction workers to correct. It has to be said that Fang Hanmin made the right choice in making Jiao Tiehui the representative of Party A.
At the beginning, Party B's construction workers praised Master Jiao for his strong sense of responsibility. After a while, they discovered that this guy was too picky! The construction requirements are almost stringent.
Entering the equipment and pipeline installation stage, this morning, Jiao Tiehui checked the positioning of several pieces of equipment. He came to the pipeline configuration site with a tape measure and a level. He used the level to check several pipelines that had been assembled. He suddenly turned around and faced A loud voice shouted in the distance: "Master Ma, come here!"
"Master Jiao, what can I do for you?" The middle-aged man whom Jiao Tiehui calls Master Ma is Party B's on-site technical representative.
"Come here quickly, you'll find out when you come here."
Lao Ma came to Jiao Tiehui and said, "What's going on in such a hurry?"
Jiao Tiehui pointed to several sections of pipelines in front of him and asked seriously: "Master Ma, who did this work yesterday afternoon?"
"What's wrong with this work?" Lao Ma walked over and looked left and right, "Master Jiao, you did a good job on this work. You didn't see anything wrong with it!"
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 pipeline is."
Lao Ma took the level and made some gestures on several sections of the pipeline. Then he looked up at Jiao Tiehui and said, "It's basically about three degrees."
Jiao Tiehui nodded, "It's almost the same. The result I measured is also about three degrees."
"Why, doesn't this angle work?"
"Master Ma, it's not you or me who has the final say whether it works or not. Take out the drawings and see what the requirements are."
Lao Ma dug out a stack of drawings from a tool box, found the relevant one, and looked at it carefully, "Master Jiao, the pipe inclination angle marked on the drawing is five degrees."
"That's right, but you just measured it yourself. The inclination angle is only three degrees. The construction quality is obviously unqualified!"
Lao Ma was a little confused, "The construction quality is not up to standard, what should I do?"
"Do I need to say more? According to the construction agreement, if the quality is not up to standard, we can only rework it!" 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 its use, right? Why do you need to rework it?"
"Without delaying use? This is what you said! How do you know that there is no delay in use? If the three and five degrees are the same, the designers simply require horizontal installation to save trouble! Let me tell you, the materials passing through these pipelines are not tap water, but It is a liquid with a certain viscosity. Based on the characteristics of the material, the technical department requires designers to consider the viscosity of the material when arranging pipelines. The inclination angle of five degrees is calculated, not the designer's imagination. The pipeline you installed has only The three-degree inclination angle does not meet the design requirements and we will not be able to use it in the future. Can it be done without rework?"
"Master Jiao, regardless of a few simple pipelines, it will take two or three days to rework. How can the construction period be guaranteed?" Lao Ma was very embarrassed.
"Master Ma, this is not a question I should answer. If you are afraid of delaying the construction period and you control the quality during the construction process, nothing will happen. You can't make the installed equipment unusable in order to ensure your construction period, right? ?”
These words made Lao Ma choke for a moment, but as the representative of Party B, Lao Ma seemed to be very experienced in dealing with such matters. "Master Jiao, besides rework, can we solve the problem in other ways?"
"Other ways, do you have any other ways?" Jiao Tiehui looked at the other party in confusion.
Lao Ma took Jiao Tiehui's hand and said, "Let's go over there and talk."
The two came to an open space and saw no one around. Lao Ma took out a box of cigarettes from his pocket, took one out and handed it to Jiao Tiehui, "Master Jiao, please smoke."
Not only did Jiao Tiehui not reach out to pick it up, but he asked instead: "Master Ma, we have been in contact for many days, right? When did you see me smoking?"
"Oh, look, I forgot. Yes, you don't know how to smoke." Lao Ma said awkwardly.
Jiao Tiehui didn't care about this, "Don't you have other solutions? Tell me quickly!"
