"Your plan can increase the efficiency by at least 30% compared to the design of the Chemical Industry Department. Xiao Zhou, are you kidding us?"
Ji Yulin almost jumped up.
The use of small ammonium nitrogen fertilizers to change urine is currently the hottest topic in the national fertilizer system.
We are indeed working on the localization of a 300,000-ton ammonia synthesis plant, but everyone in the industry knows that this cannot be done in a year or two. It would be a miracle to even achieve something successful within ten years.
There is no other reason. The technology required for large-scale ammonia synthesis far exceeds China's current industrial level. The country is now adopting a "one-buy-three-cooperation" approach, that is, purchasing foreign patented technology, cooperating in design, cooperating in purchasing, and cooperating in manufacturing. The last item of cooperative manufacturing is a big problem. The so-called four centrifugal compressor units in large-scale synthetic ammonia, namely air compressors, natural gas compressors, syngas compressors, and ammonia compressors, have very high requirements for materials and machining.
, China's machine tool industry level lags far behind that of foreign countries. Due to the restrictions of the Batumi Agreement, China cannot introduce the most advanced machine tools from abroad. This has resulted in the inability to process the precision components required for several major compressors and can only rely on
Import.
Mechanical issues cannot be solved by the chemical industry department’s hard work. We can only wait for the machinery industry to slowly catch up. It is not an exaggeration to say that this process will take 30 years. Before that, no matter how many ideas you have, it will not matter.
In vain.
If we cannot localize large-scale fertilizer equipment, we can only focus on small-scale fertilizers. In fact, until the 21st century, small-scale nitrogen fertilizers still account for half of China's nitrogen fertilizer industry. This is due to historical reasons.
The development direction of small nitrogen fertilizers is urea, which is also the consensus from the Ministry of Chemical Industry to grass-roots chemical fertilizer plants. To convert more than 1,000 small nitrogen fertilizer plants that produce ammonium bicarbonate into urea plants, the amount of work is very large and requires caution. p>
In the past few years, the Ministry of Chemical Industry has organized a group of experts to repeatedly review the program of using small nitrogen fertilizers to convert ammonium into urine, and proposed several different designs. They are also being piloted in some enterprises to test the pros and cons of each program. These programs have been passed through
It was formed through hard work, and Ji Yulin also participated in the demonstration of some plans.
He is convinced that although there are still areas for improvement in each plan, it requires practical experience. However, if an engineer from a county-level fertilizer plant pats his head, he can come up with a better plan that can improve efficiency even if
5%, that’s a fantasy.
But a strange thing happened. Zhou Xiaoyun came up with a plan and actually claimed that it could increase efficiency by 30%. Is this a way of treating the experts of the Ministry of Chemical Industry as if they were not serious?
Ji Yulin had enough reasons to believe that Zhou Xiaoyun was talking nonsense. The only thing he couldn't figure out was how this girl was stimulated to say such ridiculous things.
Zhou Xiaoyun had already pushed her plan in front of him, and he decided to take a look at the plan before seriously criticizing Zhou Xiaoyun.
"Let me see, your plan uses the full circulation method of aqueous solution. Isn't this the plan of the Ministry of Chemical Industry? ... Hey, what's going on with your design? You canceled the pre-distillation tower and replaced it with this one.
..., this should be the idea of the medium-pressure joint urination process. You have integrated the two ideas together, wonderful! Wonderful! It is really wonderful!"
Ji Yulin read a few pages and couldn't help but applaud, with an expression of ecstasy on his face.
"Jigong, are you saying that Xiao Zhou's design is indeed unique?" Xu Ying asked tentatively.
"It's not unique, but...a revolutionary breakthrough!" Ji Yulin did not hesitate to praise him, "Director Xu, let me explain to you. She proposed a brand new design during the medium voltage decomposition process.
, but fully considered the conditions of the equipment. She replaced the pre-distillation tower with a new one-section tower, and used ammonia evaporation to achieve self-stripping, which can greatly reduce the use of steam and improve thermal efficiency.
"The design of this one-section tower is similar to the very mature carbon dioxide stripping tower. It can make use of the mature experience and technical achievements of equipment manufacturing companies. Xiao Zhou made a calculation. This design alone can make every ton of urea
The steam consumption saves about 200 kilograms."
"So, Jigong thinks Xiao Zhou's plan is feasible?" Xu Ying asked.
"It's more than feasible!" Ji Yulin said, "Director Xu, what I just talked about is just one of her designs. I flipped through it roughly. It is similar to this kind of subversive innovation. At least
There are more than a dozen items. I am not sure whether all of these dozen innovations can withstand scrutiny, but I think at least half should be feasible, and they are definitely much better than the current plan of the Ministry of Chemical Industry." p>
"It's so strong!" Xu Ying was shocked.
She also comes from a production background, so she is not as good as Ji Yulin technically, but at least she can understand what Ji Yulin said. If according to what Ji Yulin said, the plan proposed by Zhou Xiaoyun far exceeds the current plans of the Ministry of Chemical Industry. In this way
As a result, the Ministry of Chemical Industry will probably have to follow Zhou Xiaoyun's plan to promote ammonium-based urine therapy.
As the proposer of the new plan, Canghai Fertilizer Factory has some reasons for requesting to become a pilot enterprise for ammonium-to-urine conversion by the Ministry of Chemical Industry.
Xu Ying thought of much more than this. The economy of Maolin Province is underdeveloped and it is almost at the bottom among the eastern provinces. The Ministry of Chemical Industry has always paid little attention to Maolin Province. When the leaders of the department go to the ministry for meetings, the seats are higher than those of other provinces.
The province is further away.
If Maolin Province comes up with an ammonium-to-urine program and overwhelms the plan developed by so many experts organized by the Ministry of Chemical Industry, can the Ministry of Chemical Industry still stand up to Maolin Province? My colleagues from other brother provinces and regions have met
People from Maolin Province need to be accompanied by a smiling face, right?
If you have the ability, don’t use the plan proposed by our Maolin Province.
If you are capable, ask the engineers in your province to come up with a high-end solution.
"Xiaoyun, you really dropped an atomic bomb quietly!" Xu Ying looked at Zhou Xiaoyun and praised.
"What, Director Xu, Jigong, do you mean that Zhou Gong's plan is feasible and that our factory can really start ammonium-based urine reforming immediately?" Qiu Guoliang asked.
Xu Ying was silent for a moment and said: "Director Qiu, Jigong has just seen Xiao Zhou's plan and thinks it is indeed very good and should be taken seriously by the Ministry of Chemical Industry. However, will the Ministry of Chemical Industry pay attention to it for this reason?
As for the selection of the Canghai plant as the national ammonium-to-urine pilot plant, it is difficult to say. After all, the ministry still has many issues to consider, and we, as subordinates, cannot make rash guesses.
"However, considering the possibility that the Canghai plant's two-coal consumption control work can be put on hold for the time being. In case the Canghai plant becomes a pilot enterprise, the early investment in equipment upgrades will be in vain.
"I still need to report this matter to the party committee of the department. However, one thing I can say in advance is that the department will definitely give a heavy reward to the plan proposed by Xiao Zhou."
