Song Chunyuan had said this, and Geng Xinren had no choice but to agree to Yu Guorong and let him invite that Gao Fan to come and take a look.
At this time, Gao Fan was at Fenglin Research Institute. Hearing Gao Yiping say on the phone that such a thing had happened, he called Pan Yue's office at the Water Chemical Engineering Group to ask what the specific situation was.
Pan Yue was actually somewhat grateful to Gao Fan. After all, he was able to work as the chief engineer at the Water Chemical Engineering Plant, and Yu Guorong's order was all due to Gao Fan. But he couldn't explain why.
, he was a little angry when he heard Gao Fan's name. When introducing the situation to Gao Fan, he would inevitably add insult to injury, saying that Yu Guorong was sure that Gao Fan had to take a look, and all the experts from the National Chemical Design Institute
All dried up.
Gao Fan knew Lao Pan's problem and automatically filtered what he said and only asked him about the main ideas of the design of the small polyester device. After Pan Yue introduced it, Gao Fan said that he felt that the design was generally good.
The problem is, since it has passed the appraisal of the National Chemical Design Institute, there is no harm in starting construction now. After finishing his work at Maple Forest Research Institute, he will seize the time to go to Shuinan and actually look at the design drawings of the device.
There shouldn't be any subversive opinions.
"I hope you can come up with some subversive opinions!" Pan Yue choked Gao Fan angrily on the phone at that time.
With Gao Fan's verbal approval, Yu Guorong felt at ease. In fact, he had no reason not to be at ease. After all, the National Chemical Design Institute was also an authoritative organization, and Yu Guorong had no reason not to believe it.
Yu Guorong paid the first payment to the hydration equipment, and the hydration equipment began to be cut and manufactured. At the same time, an engineering team was dispatched to Renqiao to carry out preliminary infrastructure construction work.
The construction site Gao Fan is seeing now is the site where small polyester devices will be built in the future.
"The progress is going very fast. Can we start installing the equipment before the end of the month?" Gao Fan commented as the two walked around the construction site.
Yu Guorong glanced at Pan Yue, and Pan Yue said: "According to the designed construction period, the equipment installation will begin next week. Now several exchange kettles for the transesterification process have been completed and can be shipped over for installation at any time. For the polymerization process,
The prepolymerization kettle and post-shrinkage kettle have been cut out, and production is very fast.”
"Hydrochemistry is indeed a well-equipped company. It's easy to produce such a device." Gao Fan complimented.
"It's not a big deal if you have it at your fingertips," Pan Yue said. "The manufacturing process requirements for several transesterification kettles are still very high. That is to say, we have introduced some advanced foreign equipment in the past two years. If we put it three years ago, just
We can’t take over the production of these cauldrons.”
Hearing Pan Yue's words, Gao Fan remembered something and said to Pan Yue: "By the way, Mr. Pan, our Maohua Machinery just signed a joint venture agreement with an old chemical machinery company in the United States two months ago. In the future, we will
The United States has introduced some advanced equipment and some advanced processes. If the hydration equipment encounters any production obstacles, you can communicate with the hydration equipment. Maybe they have some technologies that you can learn from."
"I heard about it." Pan Yue said, "I also heard that you contacted us about this matter. It's true. When you were working, you came to our hydration equipment. When you came across this kind of company that could introduce technology from abroad,
Things, you just think about your factory in Maolin."
"Uh..." Gao Fan was speechless. Lao Pan's resentment towards him was so deep that he didn't even know what to say.
Yu Guorong saw the opportunity and intervened, saying: "Gao Fan, do you want to take a look at the drawings designed by Chief Engineer Pan and others? In fact, I completely believe in the drawings designed by Chief Engineer Pan and others. However, the National Chemical Design Institute's
Dean Song said, it would be best if you take a look."
"Is that what Dean Song said?" Pan Yue glanced at Yu Guorong and murmured in a low voice.
It's obvious that you insisted on letting Gao Fan take a look. Old Song couldn't save his face, so he said it was okay to let Gao Fan take a look. Why did you turn Dean Song into a beggar and insisted on letting Gao Fan?
Have you seen the drawing?
Thinking this way, Pan Yue couldn't directly attack Yu Guorong. After all, he also knew that Yu Guorong was Party A. Even if someone could offer more than 10 million real money, Pan Yue had to give him some face.
"Are the drawings here? If it's convenient, I really want to learn about it," Gao Fan said.
"Knowing that you were coming, I brought a set of drawings here specially. They are in my office." Pan Yue said.
A group of people came to Pan Yue's temporary office at the project 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 read them here, or take them back to see?"
"I'll just take a look here." Gao Fan said. He took the drawings, spread them out on Pan Yue's desk, and began to look at them one by one.
The production process of polyester is not complicated. It is roughly divided into two processes: transesterification and polymerization, which are completed in transesterification reactors and polycondensation reactors respectively. Each reactor includes a heater, reactor, stirrer, etc., from a layman's perspective
It looks like a messy bunch of equipment when you look at it, but in the eyes of an expert, it looks clean and refreshing. There are traces of which equipment plays what role.
Pan Yue's technical foundation is very solid, and the design draws on the mature experience of large-scale polyester plants introduced from various places. Therefore, the design of this small polyester plant can be said to be quite satisfactory and has no flaws.
However, from the perspective of Gao Fan who was 40 years ahead of his time, Pan Yue's design seemed very primitive and full of flaws.
The volume matching issues of each kettle, the connection method between the fractionating column and the esterification kettle, the selection of fillers and heating media, the ratio of raw materials, and the control of the esterification mother liquor retention volume are all issues that have been repeatedly optimized in production practice in later generations.
Yes, Pan Yue's design, to use a later saying, is called "there is still a lot of room for improvement."
Although he saw these problems, Gao Fan didn't want to point them out to Pan Yue directly.
The ammonium-modified urine design he previously proposed to the Chemical Design Institute was already outrageous. If he listed 100 optimization plans for Pan Yue based on that idea now, Pan Yue would vomit three liters of blood. Gao Fan was not sure.
, but Gu Kunquan will definitely come over and ask for a biopsy, because this is really not the behavior of a normal human being.
After all, the purpose of changing ammonium to urine was to find a way out for Canghai Fertilizer Factory. Without 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 is qualified and has met the requirements to fill the domestic gap. It is not necessary for Gao Fan to add icing on the cake.
"I think there's no problem, just build it according to this design." Gao Fan said.
