Chapter 1036 The entrepreneur who understands scientific research best? Or the scientist who understands business best?
Three acids and two bases.
Nitric acid (HNO), sulfuric acid (HSO), hydrochloric acid (HCl) and sodium hydroxide (NaOH), sodium carbonate (Na2CO3).
Sodium carbonate is actually not an alkali, but a salt, commonly known as pure ash or soda, and is alkaline.
Sodium hydroxide is an alkali, commonly known as caustic soda, caustic soda, caustic soda, and flake caustic soda. It is strongly alkaline and extremely corrosive.
Both alkali metals consume a lot of electricity and coal, and have high emissions and pollution.
The preparation of caustic soda and hydrochloric acid is the most basic process route in chlor-alkali chemical industry.
By electrolyzing brine containing NaCl, NaOH (caustic soda), hydrogen and chlorine (liquid chlorine after liquefaction) are produced. The latter two can be combined to produce HCl, which is soluble in water as hydrochloric acid.
For the chlor-alkali industry, whether it is caustic soda, liquid chlorine, hydrogen, or hydrochloric acid, they can only be sold or given away at the price of garbage in the market. These products are all by-products and have to be produced.
These products are difficult to simply discharge or dispose of in an environmentally friendly manner due to their strong alkalinity, acidity or toxicity. Giving them away at a cost is more cost-effective than disposing of them in an environmentally friendly manner.
What they really need is another more valuable main product - PVC.
The main business of most chlor-alkali enterprises is the production of PVC.
This was a little secret of the original chlor-alkali industry. To them, caustic soda, liquid chlorine and hydrochloric acid were just a burden.
Because they produced so much caustic soda as a by-product that they could not give it all away even if they had to pay to get it all delivered, most of the larger ones began to produce viscose staple fibers to digest the waste product caustic soda.
Commonly known as chlor-alkali balance.
But to Emperor Yun, this is a treasure.
Because the route he wanted to take was to prepare polysilicon from chlor-alkali chemical industry.
Chlorine and hydrogen are both indispensable in the production process of polysilicon. The two react to produce hydrogen chloride, which is an important raw material for the preparation of polysilicon.
Caustic soda, also known as sodium hydroxide, is not the main raw material directly used for chemical reactions, but it plays an extremely critical role in the preparation process of polysilicon, especially under Qingyun's Yongxiang method.
First, in the preparation process of polysilicon, sodium hydroxide solution can be used to corrode and clean silicon materials to remove impurities and oxide layers on the surface.
Secondly, the wastewater generated during the polysilicon production process may contain acidic substances or other pollutants. Sodium hydroxide can be used to neutralize these acidic substances and adjust the pH value of the wastewater to meet environmental emission standards.
Of course, the most important thing is that in the production process of polysilicon, some by-products will inevitably be produced, such as silicon tetrachloride. Silicon tetrachloride can be converted into sodium silicate and hydrogen chloride by reacting with sodium hydroxide, and then participate in the preparation and production of polysilicon again, thereby increasing the output.
Therefore, Longyou, which has advantages in the chemical industry and excellent resource endowment, is the top priority for the layout of the third-generation improved Siemens method polysilicon.
It is also the key point of Qingyun's layout twenty years in advance.
He wants newcomers to this industry to have no way out.
The convoy finally arrived at a large construction site, where machines were roaring, dust was flying, and it was a busy scene.
Civil engineering work is underway and the ground has been leveled, but there is still no clue as to what exactly is going to be done.
Qin Tianshan led Qing Yun and the expert team out of the car and stood on this vibrant land.
Qin Tianshan stood in front of the expert team, bowed slightly, and said sincerely: "Thank you for your hard work, experts."
Everyone waved their hands, indicating that this was what they should do.
After a brief exchange of pleasantries, the disciples of Chen Weiping, a former professor-level senior engineer at Hualu Chemical Corporation, quickly took action.
Chemical engineering design is a professional job.
Carrying precision measuring tools, they began a detailed survey of the construction site.
In the sunshine, they are busy on the construction site, measuring, marking and recording; every action appears professional and orderly.
Not to be outdone, disciples of other experts have joined in this dialogue between science and the land. They either assist in operating the instruments or help record data, together laying a solid foundation for the upcoming project.
At the same time, the experts moved to a temporary meeting room built with prefabricated houses.
They sat around a long table and began an intense and expectant discussion.
The core topic of the seminar was the innovative idea proposed by Qing Yun - using by-products or related chemicals produced in the chlor-alkali chemical process as raw materials to produce polysilicon.
If this idea can be realized, it will open up a new path for the production of polysilicon. In this regard, Yundi said that he finally enjoyed the scientific research status of proposing conclusions and letting other bigwigs keep brainstorming.
This path will definitely be the right one.
Because this is the wisdom summary of thousands of chemical workers in China over the next twenty years.
He really wanted to laugh out loud three times, "Hey you scumbags, the conclusion is here. Your task today is to prove the correctness of my conclusion!"
As the host of the meeting, Professor Chen Yiquan first set the tone for the discussion.
His voice echoed in the conference room, steady and powerful: "Starting from the most basic chlor-alkali chemical industry to prepare anhydrous hydrogen chloride, synthesizing trichlorosilane, and finally preparing polysilicon, this set of reactions is completely feasible in theory."
As he spoke, Qing Yun turned on the computer, connected it to the projector, and displayed the complete reaction path.
"The reaction path is as follows..."
Following the guidance of Professor Chen Yiquan, the experts began an in-depth discussion. From every detail of the chemical reaction to every link of the production process, their discussion was meticulous and in-depth, and every hypothesis and inference was rigorously demonstrated.
"The yield of the front-end product can refer to the technical data of Oriental Magnolia Bark..."
As the discussion progressed, the atmosphere in the conference room gradually became heated.
The sounds of experts' discussions, the typing of keyboards, and the shuffling of papers are intertwined together to form a symphony of scientific research exploration.
But then Yan Dazhou frowned and raised his concerns, "Mr. Chen, Mr. Xiaoqing's theory is indeed feasible on paper.
However, this technical path is very long, the by-product consumption is too high, and the final product polysilicon yield will be very low.”
Qing Yun smiled and said, "Boss Yan, it's okay. We chose the chlorine chemical route because we can use most of its by-products.
The first batch of products is polyvinyl chloride, or PVC. Oriental Magnolia has a corresponding industrial chain that can digest and make PVC products.
The second batch of products, such as a mixture of tricalcium silicate, dicalcium silicate, and tricalcium aluminate, only need to add gypsum and some auxiliary materials to become silicate cement, which can also be produced by Oriental Magnolia. "
Qin Tianshan also added with a smile: "The cement produced by Dongfang Houpu is just what Huaxi Houpu needs."
Yan Dazhou, who originally thought that this route was completely nonsense, was stunned when he heard this.
He was originally skeptical about the technical route proposed by Qing Yun, thinking it was just a castle in the air and difficult to implement.
However, as Qing Yun explained and Qin Tianshan supplemented, he suddenly realized that he might have underestimated the vision of this young entrepreneur.
He burst out laughing and had a new understanding of Qing Yun in his heart.
Qingyun is not just talking about a simple chemical reaction, but building a huge industrial chain.
In this chain, each link is closely connected, and each by-product can be converted into raw materials for the next link, forming a closed loop.
Such a design not only improves the efficiency of resource utilization, but also greatly reduces production costs.
Maybe... Is this the entrepreneur who understands scientific research the best? Or is this the scientist who understands business the best?
In Qingyun’s blueprint, industrial silicon is no longer just a raw material, but the center point of the entire industrial chain.
Its production process can not only produce the required polysilicon, but also generate a large amount of PVC and cement raw materials, which are then processed on different lines to produce a wide range of finished products.
Others buy industrial silicon worth 1000 yuan for use, but Qingyun makes his own industrial silicon of the same price for his own use, and will definitely produce at least 3000 yuan worth of PVC and cement.
In this way, Qingyun can use the output of the front-end industry to cover the cost of subsequent products, because he can use most of these by-products.
In the entire China, only Qing Yun has the conditions to play like this.
Because behind him stands Hillhouse Holdings, which almost monopolizes all traditional industrial sectors. This enables Qingyun to maximize every link in the industrial chain and transform every by-product into economic benefits.
It can even be said that before producing polysilicon, he had not only recovered his costs but also made a fortune.
The experts present began to realize that Qing Yun’s innovative idea was not only a technological breakthrough, but also an innovation in the business model.
His ability of cross-border integration shocked everyone present.
