Xie Yun took on the task of writing the application and discussed some details with Qian Daguang. She was familiar with the factory construction process and understood every link from scratch. However, there was a big difference between building a factory in this era and in later generations, and she could not make any mistakes in the details.
That night, Qian Daguang stayed in the county guesthouse. Xie Yun did not go home either. He worked overtime in Secretary He's office and stayed up late to write the application.
Qian Daguang can't stay here too long and has to leave tomorrow. She has to finish the application and show it to him before he leaves.
Secretary Li and Director Zhong have gone back, and the follow-up work is led by the county, so they have nothing to do for the time being.
Xie Yun called the grain station and asked Stationmaster Xu to tell Zhang Ruifeng that she would stay in the county tonight and would not go back.
Stationmaster Xu said, "Wait a quarter of an hour and call back. I'll have your mother answer the phone. You can tell her in person so she doesn't worry."
"Okay, thank you, Station Master Xu."
Fifteen minutes later, Xie Yun called again and it was Zhang Ruifeng who answered the phone.
"Mom, I can't go home tonight. I'll go back tomorrow."
"Where do you live then?"
"I'm in the county party committee office. I have to work overtime tonight. I'll just take a nap after finishing it. I'll go home and sleep again tomorrow."
"You have to stay up late? Can't you write it tomorrow?"
"No. I have to ask a leader from out of town to look over it after I finish it, and he'll be leaving tomorrow. I'll catch up on some sleep tomorrow, it's fine. It's just like when I pulled half the night before during the rush to harvest."
"Okay, then you should take care of yourself. Don't worry about home, Mumu and I are fine."
"Hey. I'm hanging up then."
"Hang up."
Xie Yun officially started writing after dinner. She carefully considered each word and sentence and wrote a draft. After finishing it, she checked it carefully and revised some parts that she was not satisfied with. She closed her eyes and thought about it for a while, then checked it again. She found that there were still some parts that she was not satisfied with. After revising it, she thought about it again, checked it again, made some modifications, and was basically satisfied.
She took out a new sheet of paper and copied it again, making sure it was clear, logical, and free of typos.
At this time, it was almost dawn.
Xie Yun, who had been busy all night, did not feel sleepy at all.
As someone who has a little knowledge of history, Xie Yun knows that my country's fertilizer industry is underdeveloped. After the founding of the People's Republic of China, production equipment was mainly imported from the big brother. After the relationship between the two sides broke down, we focused on independent research and development, but the results were obviously unsatisfactory.
In the 1960s, China resumed its engagement with Western countries. In October 1962, the State Council decided to establish a chemical fiber group and a chemical fertilizer group, tasking both groups with gathering experts to oversee technology imports. In August 1963, the State Planning Commission established a five-member group to import complete sets of equipment, initiating a series of import efforts. Large-scale fertilizer plants producing tens to hundreds of thousands of tons annually are now imported. For example, the Dongsheng Fertilizer Plant, where Qian Daguang served as deputy director, produces 160,000 tons of urea annually. Their production line was imported in 1964. After the plant was introduced, they likely conducted research on the machinery, but the results were likely less than ideal. Therefore, in the 1970s, China launched the "43 Plan" to import equipment from abroad. It was named "43" because the plan was intended to cost 4.3 billion yuan, but ultimately cost over 5 billion yuan.
Fertilizer production lines are really introduced again and again.
During this special period, the country seemed closed, but in fact import work was still going on.
Xie Yun wanted to do something. Although she didn't have any finished equipment in her space, she did have a lot of technical information, all of which she had purchased. She also collected some publicly available technical patents.
She also bought a lot of small bits and pieces that were of no use to her at all. She wasn't interested in the products themselves, but the technology contained in the materials used in the products.
For example, she bought all kinds of fishing rods, all made of different materials and models, secondhand. She knew the wife of a fisherman who was obsessed with equipment and couldn't wait to buy new equipment. So, she secretly listed his old equipment on Xianyu (a popular online shopping platform), and Xie Yun became a regular customer.
In fact, she didn't fish at all, she just liked the material of the fishing rod.
She wanted to buy something big like a machine tool, but she didn't have enough money, and she couldn't buy it through legitimate channels. She could buy some weapons from foreign countries for nothing, but she didn't have the nerve to buy machine tools for nothing.
The proposed fertilizer plant in Qushui County, with an annual output of several thousand tons, is considered small, using domestically produced equipment. While it's certain to produce synthetic ammonia, it's unclear whether it can also produce urea.
The fertilizer production process is not complicated. Nitrogen is obtained from the air, and hydrogen is obtained by splitting water. Nitrogen and hydrogen are then combined under high temperature, high pressure and catalysts to produce synthetic ammonia. Synthetic ammonia is used as the core raw material to produce nitrogen-containing fertilizers, such as urea.
From synthetic ammonia to urea, a urea synthesis tower is needed, which has a relatively high technical content. Although China can independently produce small-scale urea synthesis towers with a daily output of about 100 tons, I don’t know whether Qushui Fertilizer Plant has this honor.
At that time, domestic urea was of low quality and high cost, and many fertilizers were actually imported.
She should do something.
What should she do?
The knock on the door interrupted her thoughts, "Come in."
Secretary He pushed open the door, holding an aluminum lunch box with a small basket on top, which contained buns and fried dough sticks.
"Xiao Xie, you've worked hard. Go wash your face and wake up. Come have breakfast first. Director Qian said last night that he can stay here until noon. If that's not possible, go and rest for a while."
