Song Xiaoli neatly took out a train ticket and handed it to Zhong Bai: "Well, tomorrow's ticket, departing from Shanping County at 8:15 in the evening, and arriving at Guangfu South Station the morning after tomorrow." ”

There is no real-name system for train tickets at this time, you can get on the train with the ticket, and after looking at the clear eighteen yuan five fares written on the ticket, Zhong Bai took it and subconsciously wanted to pay the money out of his pocket, and waited for his hand to reach into the empty trouser pocket before he smiled dumbly and said to Song Xiaoli.

"That...... I don't have so much money on me, so I'll go to the workshop and find a worker to get the money for you. ”

"Don't be in such a hurry, I don't wait for the money to buy things." Song Xiaoli was amused by Zhong Bai's embarrassed appearance: "It's not appropriate for you to go to him during work hours, right?" Anyway, he's going to come to the train station tomorrow, so you can let him come to the station restaurant for me at that time. ”

Since he met Zhong Bai, he has always given Song Xiaoli the image of a very smart and handsome young man in the provincial capital, and now when he sees that Zhong Bai can't pay for it, Song Xiaoli's heart is a little dark.

Zhong Bai thought for a while and asked, "By the way, why did you come here at this point?" Don't go to work? ”

"We're working shifts, and now I'm resting." Song Xiaoli covered her mouth and smiled.

At this moment, Shan Jianping's shout came from the office: "Xiao Zhong, come in quickly!" ”

"Then I won't delay you from going to work, go back first, goodbye."

Zhong Bai wanted to subconsciously ask the other party for a mobile phone number, but suddenly reacted that it was 1981, but before he could react, Song Xiaoli had left in a hurry.

After being reborn, it can be said that there are only two people of the opposite sex who know Chu Juan and Song Xiaoli, compared to Chu Juan's pungent and straightforward, Song Xiaoli seems to be much more sensible.

The service is also very reliable, and the train ticket was silently completed in less than a day, and even the ticket was sent to the door to advance the money first!

You must know that eighteen yuan and five in the first year is not a small number, even if there is trust between people, but in exchange for you, are you willing to buy a ticket out of your own pocket for someone who has only seen two sides and asked you to watch a movie? I have to use my father's relationship!

There have been a lot of things in the factory in the past two days, and tomorrow it seems that Yu Dongfeng can only go to the train station by himself, and Zhong Bai doesn't know when he will be able to see Song Xiaoli again, so he has to shake his head and walk into the office of the technical department.

"Section Chief."

"Well, come and explain to me, why do you say that you can do without the transformation furnace and heat exchange equipment? How exactly does this work? Shan Jianping asked puzzled, pointing to one place.

Zhong Bai pondered for a moment and said, "This is a long story......

This isothermal transformation technology was discovered and perfected in China in 2012, and was launched on a large scale in 2013 to improve the production efficiency of synthetic ammonia.

Isothermal conversion technology is a new form of synthetic ammonia transformation process.

At present, the main technology for the production of nitrogen fertilizer in China is the synthetic ammonia transformation process, which was born in 1913 and has been close to 100 years.

This process is mainly used for the transformation reaction of carbon monoxide and water vapor on a catalyst to produce hydrogen and carbon dioxide. After changing from atmospheric pressure to pressurization; from high temperature transformation to medium and low temperature transformation; The catalyst is converted from iron-chromium and copper-zinc to sulfur-resistant cobalt-molybdenum from low CO multi-stage adiabatic shift to high CO multi-furnace transformation, which can be said to be very mature.

The core of isothermal shift technology is to place the heat exchanger in the catalyst bed of the reactor, remove the reaction heat through the by-product steam, keep the catalyst bed at low temperature and constant temperature reaction, save multiple transformation furnaces and heat exchange equipment, and greatly shorten the process.

Remember the converter you checked in the workshop before?

If this technology is used, the old Soviet-style converter furnace can be honorably laid off.

“…… That's pretty much the way it goes. Zhong Bai carefully explained the core concept and key links of isothermal conversion technology to Shan Jianping, and the other party was dumbfounded.

After a while, Shan Jianping stammered and asked, "Xiao Zhong, are you ...... You mean, if this technology is implemented, then we won't need a converter to produce nitrogen fertilizer in the future? ”

"Yes, that's understandable." Zhong Bai nodded: "But the supporting facilities need to keep up, and new reactors must be purchased, the production process must be redesigned, and workers must be trained to operate." ”

"Oh my God, how much does this cost all this time out? How much time does it take? Shan Jianping was already stunned.

Zhong Bai only knew that in his previous life, this technology was popularized and applied on a large scale across the country in just one year, and the effect was very good, it seemed that there was not much investment, but he really didn't ask how much the specific equipment cost.

So Zhong Bai shook his head and said: "I don't know the price very well, don't worry about the time, as long as the equipment is in place, the training can be done in one day, and the production can be carried out step by step." ”

"How much capacity can I expect to increase?"

"According to the current scale of our factory, at least 100%." Zhong Bai thought for a while and added: "In addition, because of the improvement of energy utilization, the cost of raw materials saved is also very objective, at least it can be reduced by about 30%. ”

Hearing this number, Shan Jianping's eyes lit up, but it was only a moment away.

"Okay, even if, as you said, this new technology has such a good effect, where can I buy the new supporting facilities? Also, the financial situation of the factory has been tight recently, and if you want to apply for funding from Director Chu, I am afraid it will be a little difficult...... After all, listening to his tone in the office just now, it should be improved on the basis of existing equipment, rather than buying new equipment on a large scale to upgrade! Isn't this a castle in the sky? ”

When Shan Jianping said this, he reminded Zhong Bai.

That's right, in more than 20 years, these new reactors can basically be bought casually in a medium-sized city, but this is in 1981, and the manufacturers who produced them really don't know if there are any in China!

"Well...... Then I will think about it again and try to come up with a way to increase production capacity without replacing equipment. Zhong Bai quietly withdrew the manuscript of the isothermal transformation technology he had just written to Shan Jianping and said.

"Okay, but it's a very advanced technology, and although I've never heard of it before, it makes sense to see that the formulas and processes on the materials you wrote are written to the key points. Then you work hard to think about it, I have a little personal matter, and I go out for half an hour. ”

"Okay, Section Chief." Zhong Bai breathed a long sigh of relief, and said in his heart Fortunately, you didn't ask about the source of this technology, otherwise I'm afraid it would take another half a day to come back.

Shan Jianping got up, patted Zhong Bai on the shoulder and left the office, leaving him alone and began to think hard.

This old production line, do you want to increase production capacity without buying new equipment?

A new idea formed in his mind, and Zhong Bai's eyes suddenly lit up!
