Standing at the gate of Anyun University and looking at the energetic college students in the 1980s, Ran Jiang did see some things that were very different from those when he was in college.

After feeling moved, I went to the school and found the teaching building of the chemistry department based on my memory. As soon as I entered, I met several teachers who taught him. After greeting him one by one, I came to Professor Lu's office.

Ran Jiang came back this time to ask Professor Lu for advice. Professor Lu is a cutting-edge expert in the field of chemical engineering in China and has a very good understanding of the latest progress in the chemical industry abroad. He can know that FRC technology has lagged behind, but he still got it from Professor Lu.

But I didn’t understand it systematically at the beginning, so I could take this opportunity to make up for the missing courses, and at the same time provide stronger evidence for the Jinzhou Factory’s technological innovation route.

Ran Jiang carefully explained his work experience during the period of time to Jinzhou Factory, and then explained his purpose of this trip. "Professor Lu, I came here mainly to ask you for help, collect more information about FRC technology, and also find a technical route that is more suitable for Jinzhou Factory."

If you want to change it to the computer or the Internet field, you don’t need to ask for help. Ran Jiang is very familiar with the development route in the next few decades, but he is relatively unfamiliar with chemical engineering. He just vaguely remembers several hot news with a very big impact, and he only knows a rough idea, but does not know more detailed situations.

"Xiao Song, it seems that work is very effective in training people! You are much better at speaking and doing things now than when you were studying!" Professor Lu sighed first.

Then he said, "FRC technology has indeed been eliminated by developed countries such as Europe, America and Japan. The most critical issue is..."

Professor Lu explained to him in detail that there are many reasons, but the most important thing is the economic issue. "... Our country is so tight now that it would have been backward if it was spent on a large price to buy a production line that could not bring benefits to the manufacturer, it would be inappropriate."

"I'll make a list for you. You can find the documents you need according to the list!" As soon as he wrote a few strokes, Professor Lu slapped his head, "I almost forgot that you have graduated now and the school library can't be in. If that's the case, I'll find a student to collect it for you!"

"Thank you, Professor Lu!" Fortunately, Ran Jiang had already brought all his savings before coming, so he should be able to afford the copying fee. When he went back, he could just find Secretary Shui to reimburse him.

"When it comes to ethylene production in our country, it can be divided into two stages. The first stage began in 1962, when Lanzhou Petrochemical Company completed and put into production, marking the birth of my country's ethylene industry."

"my country's ethylene industry has achieved a historic leap from scratch. Although compared with foreign countries, my country's ethylene equipment scale is small and its process technology level is backward, the entrepreneurial process at this stage has opened a new chapter in the development of China's ethylene industry."

"Lanzhou Petrochemical Company's technology was introduced from the Soviet Union and is one of the 156 key projects that the Soviet Union aided our country! I remember that at that time, it adopted a sand furnace using crude oil as raw material to make ethylene equipment, and there were also major equipment such as high-pressure polyethylene, polypropylene, acrylonitrile, polypropylene, acrylic fiber, etc. Since then, most other domestic companies have followed similar technologies."

"After that, Lanzhou Petrochemical introduced sand furnace cracking and cold detection separation technology from Dongdruchi Company, which uses crude oil flash evaporation and oil slitting as raw materials, further improving production efficiency."

"Later, due to well-known reasons, our relationship with the Soviet Union became colder, and many experts withdrew, so we lost a lot of opportunities to communicate and learn from abroad, and ethylene production technology gradually lags behind!"

"After the reform and opening up, we opened the country again. Only then did we realize that the development of the world's ethylene industry is really too fast, and the technology we are using is far behind!"

"According to my understanding, the current ethylene production technologies mainly include synthesis gas ethylene, catalytic hydrogenation technology, tube cracking technology, etc. The FRC technology that your Jinzhou factory is preparing to introduce is a branch of synthesis gas ethylene technology."

"But as you said just now, FRC technology has lagged behind. Nowadays, the most popular internationally, representing future development prospects are mainly the technologies of S&W and Rums."

"S&W is located in the United States and is one of the world's famous ethylene patenters. From the 1940s to now, the company has built nearly 100 ethylene units around the world, with an ethylene production capacity of more than 10 million tons/year, accounting for about one-quarter of the world's total production!"

"The USC-USX cracking furnace technology it developed is at the world's leading level! It has great potential to explore and has a better future prospect."

"Rumes is also located in the United States and has the same strength as S&W. Since the 1960s, it has developed an SRT-type cracking furnace using branched variable diameter furnace tubes, which has well achieved the requirements of cracking process conditions and has the advantages of energy saving and low cost."

"To this day, SRT technology has developed to the fourth generation, and there is still room for improvement and upgrading! Whether it is USC-USX technology or SRT technology, it is much better than FRC technology!" Professor Lu gave his own opinion.

"I can also make a list of USC-USX technology and SRT technology information for you, and I will also list some of the other companies. Jinzhou Factory will choose a technical route. The advanced level is important, but the cost needs to be considered!" Professor Lu wrote slowly.

After he finished writing it and handed it over to Ran Jiang, he took it back after reading it, and asked his graduate students to help collect and copy the materials.

After thanking Ran Jiang asked curiously, "Professor Lu, what you said just now, the technology of these two companies is so advanced and has such a great influence. Why does our Jinzhou factory still prefer FRC technology?"

"Our factory is not making a decision. In order to find a suitable project, General Manager Liu and the people from the rectification office collected a large amount of information for comparison, and then they decided to introduce FRC technology!"

"I think there may be several reasons. First of all, FRC technology was developed by Japan's Osaka Gas Company. Japan is close to our country and has a preconceived advantage. S&W and Rums previously focused on the European, American and Middle East markets, and have been dealing with our country for a short time, so there is less information."

"Secondly, the defects of FRC technology were discovered by the industry in the past two years. Previously, due to the good market conditions, the defects of FRC technology were not prominent; but with the oil crisis in the 1970s, the development of the ethylene industry suffered a certain blow. In this case, the defects of FRC technology are relatively fatal!"
