Siheyuan: I am different He Yuzhu

Because He Yuzhu resolutely took great risks to offer his advice to Li De, this heroic act allowed the top leaders of Rabbit Country to gain insight into the true state of agriculture in 1958. In this way, they successfully avoided the possibility of making wrong decisions due to false agricultural data. Not only that, He Yuzhu also took the lead in igniting the Great Leap Forward in the steel industry, effectively preventing the vigorous national steel-making movement that was bound to occur in the course of history. It was thanks to his foresight that a large number of rural laborers were not constrained and occupied by this unnecessary movement. Because of this, major crops such as grain finally got rid of the embarrassing dilemma of "high yield but low harvest" and finally ushered in a steady increase in production.

After the top leaders of the Rabbit Country completed the careful adjustment of relevant policies in the agricultural field, they immediately turned their attention to the local government where the exaggeration was extremely prevalent, and launched a vigorous rectification action. During this rectification process, many leading cadres who did nothing about the exaggeration problem and were idle in their positions were punished as they should be; and those cadres who deliberately falsified and deceived their superiors and subordinates were held accountable without mercy. After this storm-like rectification, the overheated and blindly aggressive thoughts in all walks of life in the Rabbit Country were finally effectively curbed and suppressed. At the same time, He Yuzhu's noble behavior of daring to stand up and speak for justice also successfully attracted the close attention of Li De, laying the groundwork for He Yuzhu to enter the top level in the future.

After 587 long and arduous experiments, the urea synthesis research and development team of the Fourth Research and Design Institute of the Ministry of Chemical Industry finally successfully determined the best solution! It turned out that when the strictly purified ammonia and carbon dioxide were accurately mixed in a specific molar ratio of 2.8 to 4.5 and flowed into the synthesis tower together, the pressure in the tower was carefully controlled between 13.8 and 24.6MPa, the temperature was stably maintained in the range of 180 to 200℃, and the reaction materials were ensured to stay in it for 25 to 40 minutes.

Under such conditions, the efficiency of urea synthesis will reach its peak! In the end, they got what they wanted, a urea solution containing excess ammonia and ammonium carbamate. Next, by cleverly implementing the decompression and cooling operation, ammonia and ammonium carbamate can be effectively separated from the solution. Subsequently, the remaining urea solution is evaporated to increase its concentration to an amazing 99.5%. Finally, these concentrated urea solutions are cooled to become the urea crystals they dream of.

Zhang Jinyue was filled with joy, holding the urea he had just manufactured, and immediately went to find He Yuzhu. He couldn't wait to pass on this exciting good news to him as soon as possible, because Zhang Jinyue knew very well that without He Yuzhu's full support, they would never have been able to overcome the many key process parameter problems in urea synthesis in such a short time. While the carbonization method for producing ammonium bicarbonate was still a difficult attempt, they took the lead in solving the technical problems in the large-scale production of urea, which would completely change the layout and process of the fertilizer industry in Rabbit Country. How could this great honor be without He Yuzhu who provided them with strong support?
