Sail across the sea

Chapter 323: Propose some subversive opinions
Since Song Chunyuan said so, Geng Xinren had no choice but to agree to Yu Guorong's request and ask him to invite Gao Fan to come and take a look.

At this time, Gao Fan was at the Fenglin Research Institute. After hearing Gao Yiping's words on the phone, he called Pan Yue's office at the Water Chemistry Department to inquire about the specific situation.

Pan Yue actually felt a little grateful to Gao Fan. After all, it was Gao Fan who made him the chief engineer at the Water Chemical Design Institute and Yu Guorong's order. But he couldn't explain why he got so angry when he heard Gao Fan's name. When he introduced the situation to Gao Fan, he inevitably exaggerated it, saying that Yu Guorong had insisted on Gao Fan's approval and left out all the experts from the National Chemical Engineering Design Institute.

Gao Fan knew Pan's problem, so he automatically filtered out what he said and only asked him about the main ideas of the small polyester device design. After Pan Yue's introduction, Gao Fan said that he felt that the design was generally fine, and since it had passed the appraisal of the National Chemical Engineering Design Institute, it would be fine to start construction now. After he finished his work at the Fenglin Research Institute, he would take the time to go to Shuinan to actually look at the design drawings of the device, and he expected that there would be no subversive opinions.

"I actually hope you can come up with some subversive ideas!" Pan Yue retorted to Gao Fan in a bad mood on the phone at that time.

After receiving Gao Fan's verbal approval, Yu Guorong felt relieved. In fact, he had no reason not to feel relieved. After all, the National Chemical Engineering Design Institute was also an authoritative institution, and Yu Guorong had no reason not to believe it.

Yu Guorong paid the first installment of the payment to Shuihuashe, and Shuihuashe began cutting materials and manufacturing. At the same time, it sent an engineering team to Renqiao to carry out the preliminary infrastructure work.

The construction site that Gao Fan is seeing now is the site where a small polyester device will be built in the future.

"The progress is quite fast. We can start installing the equipment before the end of the month, right?" Gao Fan commented as he walked around the construction site with the two of them.

Yu Guorong glanced at Pan Yue, and Pan Yue said, "According to the designed schedule, the equipment will be installed next week. Now the several exchange kettles for the transesterification process have been completed and can be transported here for installation at any time. The prepolymerization kettle and post-condensation kettle for the polymerization process have been unloaded, and production will start very quickly."

"The Water Chemical Equipment Group is indeed strong and capable. It should be a piece of cake for them to produce a set of equipment like this." Gao Fan complimented.

"It's not that easy to do," Pan Yue said. "The manufacturing process requirements for several transesterification reactors are still very high. That's why we have introduced some advanced equipment from abroad in the past two years. If it were three years ago, we would not be able to manufacture these reactors alone."

Hearing Pan Yue's words, Gao Fan remembered something and said to Pan Yue, "By the way, Chief Engineer Pan, our Maohua Machinery just signed a joint venture agreement with a well-established chemical machinery company in the United States two months ago. In the future, we will introduce some advanced equipment and some advanced processes from the United States. If the water chemical equipment encounters any production obstacles, you can communicate with Maohua Machinery. Maybe they have some technology that we can learn from."

"I heard about it." Pan Yue said, "I also heard that you were the one who contacted us about this matter. Really, when you were working, you looked for our water chemical equipment, but when you encountered something like this that could introduce technology from abroad, you only thought about your Maolin factory."

"Uh..." Gao Fan was speechless. Old Pan's resentment towards him was really deep, and he didn't know what to say.

Yu Guorong saw the opportunity to interrupt and said, "Gao Fan, do you want to take a look at the drawings designed by Chief Engineer Pan and his team? In fact, I completely trust the drawings designed by Chief Engineer Pan and his team, but Director Song of the National Chemical Engineering Design Institute said that it would be best if you take a look."

"Is that what Dean Song said?" Pan Yue glanced at Yu Guorong and muttered in a low voice.

It was you who insisted on letting Gao Fan take a look, and Old Song couldn't save face, so he said it was okay to let Gao Fan take a look. How come you said it became Dean Song begging Gao Fan to take a look? Thinking this way, Pan Yue didn't want to confront Yu Guorong directly, after all, he knew that Yu Guorong was the first party. Just because he could come up with more than 1000 million in real money, Pan Yue had to give him some face.

"Is the drawing here? If it's convenient, I really want to learn it." Gao Fan said.

"Knowing you were coming, I brought a set of drawings with me. They are in my office," said Pan Yue.

The group came to Pan Yue's temporary office at the construction site. Pan Yue took out a few rolls of drawings, handed them to Gao Fan, and said, "These are the drawings of the main equipment. Do you want to see them here or take them back?"

"I'll just take a look here." Gao Fan said. He took the blueprint, spread it out on Pan Yue's desk, and began to look at it one by one.

The production process of polyester is not complicated. It is generally divided into two steps: transesterification and polymerization, which are completed in transesterification reactors and polycondensation reactors respectively. Each reactor includes a heater, reactor, agitator, etc., which may seem like a mess to laymen, but are neat and tidy to experts, who can clearly see which equipment plays which role.

Pan Yue has a very solid technical foundation, and the design draws on the mature experience of large-scale polyester equipment introduced from various places. Therefore, the design of this small polyester equipment can be said to be quite standard and has no major flaws.

However, from Gao Fan's perspective, which was 40 years ahead of its time, Pan Yue's design seemed very primitive and full of flaws.

The problems of volume matching of each kettle, connection method between distillation column and esterification kettle, selection of filler and heating medium, raw material ratio, and control of esterification mother liquor retention volume were all repeatedly optimized in production practice in later generations. Pan Yue's design, to use the words of later generations, "still has a lot of room for improvement."

Although he noticed these problems, Gao Fan didn't want to point them out to Pan Yue directly.

The ammonium-to-urine design he had proposed to the Chemical Engineering Design Institute was already incredible. If he were to list 100 optimization plans for Pan Yue based on that idea, Gao Fan was not sure whether Pan Yue would vomit three liters of blood, but Gu Kunquan would definitely come over and ask for a biopsy on him, because this was not the behavior of a normal human being.

After all, the purpose of converting ammonium to urine was to find a way out for the Canghai Fertilizer Plant. If we didn't come up with some amazing designs, it would not be enough to impress the Chemical Engineering Design Institute.

This time, the small polyester device designed by Pan Yue was qualified and had reached the requirements to fill the domestic gap. There was no need for Gao Fan to add icing on the cake.

"I don't think there's any problem. Let's build it according to this design." Gao Fan said.
