In the corridor of the experimental building of Shenyang Institute of Chemical Technology, 55-year-old Professor Wu Jianhua looked out of the window with his hands behind his back and said with a smile, have you seen that forest? There are 9 species of wild birds there. Our school has developed rapidly in recent years. This year Our scientific research project won the second prize of the National Science and Technology Progress Award, and everyone here is proud of it. His voice was like a bell when he spoke, and his not tall figure was deeply engraved in front of the green window.
On January 9 this year, at the National Science and Technology Conference held in the Great Hall of the People, Professor Wu Jianhua stepped onto the podium quickly to a round of applause, and received the certificate of the second prize of the National Science and Technology Progress Award. Previously, the awards and honors awarded by Professor Wu Jianhua, which can be described as hills, are enough to make people pay homage to this leader in the chemical industry. As the highest honor in China’s scientific and technological circles, the second prize of the National Science and Technology Progress Award was completed by the research team led by Professor Wu Jianhua alone. From this point of view, its significance and the influence of the subject itself in the industry have far exceeded the award itself .
Still water running deep
When he first developed the subject of static mixed reaction technology, Wu Jianhua had just graduated with a master’s degree.
From then to now, more than 20 years have passed, and Professor Wu Jianhua has become a doctoral supervisor of Shenyang Huagong Institute of Technology and a postdoctoral supervisor of Tianjin University. For him, the past twenty years consisted of countless sleepless nights. On the reflection of time, there were faint shadows of Professor Wu and his team walking back and forth in front of the experimental equipment.
From “static mixing nitrobenzene washing device” to “single-tube four-rotation static mixing tube chlorohydrin method propylene oxide production technology and equipment”, from provincial science and technology progress award to national science and technology progress award, Wu Jianhua’s Static mixing reaction technology has achieved great success.
Wu Jianhua, who has the demeanor of a scholar, looks very quiet, and the halos on his head seem to be far away from him. In the opinion of Prof. Wu’s student, Dr. Gong Bin, Prof. Wu is very diligent at work. As the secretary of the school’s party committee, he is entangled in government affairs. At the same time, he has many scientific research projects at hand, but he will definitely take the lead when encountering new topics. Sometimes I don’t have time to eat in the cafeteria at noon, so I eat boxed lunches and instant noodles with the workers in the laboratory.
Under his leadership, all members of the research team gave up winter and summer vacations and weekend breaks, and devoted themselves to the research of the research project.
The process became easier in Professor Wu Jianhua’s narration, and a string of very professional-sounding nouns was like a bible to the reporter’s ears. Professor Wu Jianhua showed a good-natured smile and resolved the reporter’s embarrassment, “I major in chemical engineering. To be honest, I don’t understand the professional terms in the field of chemistry as if I were listening to a foreign language.”
Regarding the research and development topics in these years, he casually gave reporters a popular metaphor, “It’s like raw materials and a stove. If you fry vegetables in a pot, if the fire is too hot, it will be easy to burn; if it is too slow, it will not be easy.” Cooking, we developed a series of devices based on the static reaction technology platform is the stove, the function of this stove is to make the fried dishes easy to cook without wasting.” It is a skill to explain the academics so plainly.
Stay true
Back in time to the 1990s.
With the sharp increase in the demand for propylene oxide in the domestic market, the existing domestic production technology that consumes a lot of raw materials and produces a lot of waste gas is facing elimination, imports have surged, and a large amount of RMB has flowed out of the country.
To change the status quo, we must take an innovative path that others have not gone through.
At that time, this taciturn professor and his team had just presided over the completion of the “Static Mixed Nitrobenzene Scrubber” project, and no one could predict what kind of achievements this humble doctor would make.
A few years later, Wu Jianhua and the others achieved success.
The reporter found this paragraph from a thick stack of materials. Professor Wu Jianhua used the static reaction technology as a platform to lead a team to develop a series of key technologies, processes and supporting technologies for production expansion, which became the first in the world and achieved unprecedented success. In the words of experts from the State Economic and Trade Commission, the successful research of this project will improve the technical level of my country’s organic chemical raw material production, realize high-tech industrialization and use high-tech to transform traditional industries, maintain the sustainable development of the chemical industry, and promote my country’s chemical industry. Technological progress is of great significance.
With technical achievements, Wu Jianhua and his team did not stop, but accelerated the pace of technology industrialization.
In 1999, in order to expand the propylene oxide production facility, Liaoning Jinhua Chemical (Group) Co., Ltd. cooperated with Wu Jianhua and his team to carry out technological innovation, which doubled the production capacity of the original equipment. The news spread quickly in the industry, and since then, “It’s not us looking for the company, it’s the company looking for us. Some projects that don’t have time to complete have to think of some tactful excuses to stop them.”
In March 2006, Zhu Jian, President of Liaoning Aoke Group, took the initiative to find Professor Wu.��It is hoped that Professor Wu can use static mixing technology to improve their production equipment and break the bottleneck of enterprise production expansion.
In this year’s outstanding expert intelligence docking project held by the Organization Department of the Provincial Party Committee, this project in cooperation with Oak Company was included in it. The international competitiveness of derivative fine chemicals has played a huge role in directly changing the situation of my country’s annual imports of glycol ethers and ethanolamines, and it has also been listed as the “Eleventh Five-Year Plan Chemical Project” of our province, applying for a major provincial research project .
In Liaoning Aoke Company, the annual production capacity of a production line is 15,000 tons. The “static mixing ethoxylation technology process” developed by Wu Jianhua was used to transform the original equipment. The annual production capacity of each production line will reach 30,000 tons. After the promotion by the group, the annual sales will reach 5-1 billion yuan, and the profits and taxes will be 50-80 million yuan.
Standing in the production workshop, Zhu Jianmin, president of Liaoning Aoke Group, pointed to the production line that was going to be tested in August. Compared with that, the energy consumption per unit product will be reduced by more than 30%. At that time, it will have a profound impact on the technological progress of my country’s ethylene oxide deep processing industry.
