Chapter 84 Showing off one’s edge
"...The method I am using now is to modify only the catalyst basket mechanism while leaving the original tower shell and inner cylinder catalyst bed unchanged, so that the gas flow changes from the original axial flow to radial axial flow, and the bed temperature is still adjusted with cold shock gas between layers." Xu Qiang was obviously in the state at this time, and he continued: "My modification plan has little impact on the overall equipment. It can be modified during the workshop maintenance period. The construction is simple and the cost is low..."
In his previous life, Xu Qiang had participated in many technical discussions, so when faced with such occasions, even if the people sitting opposite him were the best chemical experts in the province, Xu Qiang was still able to remain calm and not show any stage fright.
Even Liu Biao and Gao Zhiguo, who were sitting next to him, expressed approval of Xu Qiang's performance.
"Comrade Xu Qiang, I noticed that your plan also calculated the various indicators after the transformation. Can you tell us more about it?" Cao Liansheng suddenly asked.
"I have also calculated the indicators after the equipment transformation..." Xu Qiang paused, and then said: "After the transformation, the tower pressure drop is reduced from the original 0.62MPa to 0.25MPa, which can increase the space velocity and increase production. At the same time, small-particle catalysts can be used to increase the ammonia synthesis rate. Therefore, the ammonia concentration out of the tower can be increased to 15%, and the energy consumption per ton of ammonia can be reduced by about 0.5 GJ."
In fact, the main raw material for producing ammonia is coal, so when evaluating its energy consumption, the most critical indicator is called "ton of ammonia and coal consumption", that is, the raw material coal and fuel coal consumed for each ton of synthetic ammonia produced. In addition, the electricity consumption indicator is also calculated per ton of ammonia.
According to what Xu Qiang had learned from the workshop and factory database, the energy consumption of the chemical workshop of Shengli Machinery Factory is quite high, but the output is very low. For example, in later generations, some small nitrogen fertilizer companies in China have been able to achieve the so-called "three thousand", that is, the coal consumption per ton of ammonia is less than 1000 kilograms, the electricity consumption is less than 1000 kilowatt-hours, and the process energy consumption is less than 1000 million kilocalories.
But in Xu Qiang's chemical workshop, the production of one ton of ammonia consumes 3140 kilograms of coal, the electricity consumption is 1480 kilowatt-hours, and the process energy consumption is 1621 million kilocalories, which is more than twice the level of later generations.
Xu Qiang's renovation plan is to improve the ammonia synthesis rate and reduce energy consumption losses through hardware renovation, especially the renovation of the ammonia synthesis tower, so as to achieve the goal of increasing production.
Although there is still a big gap between us and the advanced level of later generations, as long as we can reach a level similar to that of other fertilizer factories of this era, our products can fully participate in market competition.
"Comrade Xu Qiang, I also saw the transformation of the hydrolysis system of the urea plant in your proposal. Do you think your proposal can adapt to the current production line of your workshop?" As soon as Xu Qiang finished speaking, another expert present asked a question.
"Regarding the transformation of the urea plant hydrolysis system, the main reason is that the hydrolysis plant currently used in our workshop is too outdated. It is a product from before the liberation, and the loss of tons of urea is large, which seriously increases production costs..."
Xu Qiang answered the questions from the experts on the scene fluently, as if he knew everything. As a result, the experts on the scene went from doubting at the beginning to listening attentively now, and some even took notes with pens, which also showed their recognition of Xu Qiang's professionalism.
In fact, under normal circumstances, Xu Qiang did not want to show off his chemical knowledge. After all, for a time traveler, showing off his talents would sometimes cause some unnecessary trouble. But now it concerns the fate of the factory and his personal future, so Xu Qiang must get the recognition of these people.
Next, these experts raised several questions in succession, and Xu Qiang answered them all. Sometimes he even felt that explaining by words alone was not enough, so he asked the staff to bring paper and pen, and he drew diagrams and did calculations on the spot, just like a university professor.
At this moment, not only Liu Biao, but even Gao Zhiguo was stunned. Before this meeting, he could never have imagined that the top experts in the province who were over fifty years old and well-known in the industry would listen so attentively to the lecture of a young man in his early twenties. This was an incredible scene no matter what!
Time passed by minute by minute. This discussion started before two o'clock and lasted until nearly five o'clock. During the three hours, Xu Qiang did not drink a sip of water and gave a high-energy explanation throughout the whole process. Finally, all the questions raised by several experts were answered by Xu Qiang, and the scene immediately became quiet.
"Comrade Xu Qiang, I would like to ask you, what was your original intention in making this technical reform plan?"
Seeing that the experts on the scene stopped talking, Gao Zhiguo asked Xu Qiang with a smile.
"Actually... the factory had this military-to-civilian product collection activity before, and the first prize was 800 yuan. My family is poor, and I want to earn some money to marry a wife, so I signed up..." Xu Qiang said after a moment of hesitation.
"Hahaha!"
Xu Qiang's words caused laughter at the scene, and even Liu Biao, who was always serious, started laughing.
"Haha, that's understandable." Gao Zhiguo nodded with a smile, and then asked: "Then if you have anything else to say, such as any ideas you have about this project, you can speak freely."
"It's like this. Now that the national policy is good, our village has also begun to implement the land contracting system for each household. In the past, it was a big pot meal for the production team, but now everyone takes care of themselves and wants to grow more food and make more money." Xu Qiang paused and continued, "So in order to increase production, we have a great demand for fertilizers here, but the fertilizers in the town supply and marketing cooperative are always out of stock. So I think that if our factory can also produce a large amount of fertilizers, it will not only make the factory more money, but also allow our farmers to buy enough fertilizers and grow more food. This is also my hope..."
Xu Qiang was also experienced in dealing with such occasions, and his words were clearly somewhat sensational and suggestive.
Technical exchanges should only be limited to peers. Never discuss technology with leaders, as this will only embarrass them. When facing leaders, you must never teach them what to do; you can only give them some hints.
No matter what era it is, having skills without social experience is not enough. Xu Qiang had already honed his proficiency in this regard in his previous life.
"Clap clap clap!"
As soon as Xu Qiang finished speaking, everyone at the scene applauded, and Gao Zhiguo also showed a satisfied smile on his face.
"Today's discussion was very successful. Thank you all for your hard work." Gao Zhiguo saw that the time was almost up, so he continued, "I have already notified the guesthouse. Let's have a meal together later to welcome the two distinguished guests from Shengli Machinery Factory. Let's also do our best to be the hosts and enhance the relationship between comrades..."
