Chapter 1272

"Of course, of course." There was a comprehension expression on Wu Nanhai's face.

After the brief and grand groundbreaking ceremony, Ma Qianju symbolically pulled down the feed switch, and the prepared [-] firecrackers went off immediately. With the cheers of the crowd, the ceremony ended. There were no students from Fangcaodi to help out. There are also no banquets and other similar "atmosphere" content.

Recently, the General Office of the Senate issued a notice of "Practice Diligence and Thrift and Oppose Extravagance and Waste", requiring the elders of all departments to minimize unnecessary celebration ceremonies and reduce official entertainment etiquette expenses, so the scene was much smaller.However, regular visits after the groundbreaking ceremony are indispensable.

Visiting and studying is the most effective means of brainwashing, so the Senate will not let go of any such great opportunity.These customers of Tiandihui have tried chemical fertilizers in a small amount, and have already experienced the miraculous effect of this "fertile field powder". They heard that this factory is specialized in the production of "fertile field powder", and they all want to see what this "fertile field powder" is. How it was made, all of them followed Ji Tuisi to visit the modern fertilizer production with great interest.

The Lingao No. 1 Fertilizer Factory has a big name and occupies a lot of land, but so far only 4 tons of ordinary calcium superphosphate and [-] tons of sulfuric acid supporting projects have been built.There is also a large area of ​​free land in the factory area, which is reserved for new projects in the future.

A large amount of sulfuric acid is used in the superphosphate production line. According to the annual production capacity of 1 tons, 3800 tons of sulfuric acid is needed every year. Such a large amount of sulfuric acid cannot be transported from the current sulfuric acid plant and coal coking joint plant, but the chemical port lacks long-distance Safe and a large number of transport containers; secondly, triacid and dialkali are the basic products of chemical industry, and from this point of view, the more production capacity, the better.Although the sulfuric acid plant and the coal coking joint plant can produce a large amount of sulfuric acid, there are many places where they need to be used. Enterprises such as chemical fertilizer plants that need stable supply all year round are more suitable for self-built facilities

过磷酸钙生产线由14×7平方米的干燥、14×10平方米的化成、24.5×10平方米的包装三个车间组成，有包括30平方米烘坑、2.5平方米振动筛、半连续化成室、提升机、硫酸高位槽、混合锅等10套设备，员工定额150人，占地面积0.264公顷。

This project requires 5600 tons of phosphate rock each year, so the Planning Institute specially arranged a 200-ton transport ship to and from Xisha Island to transport struvite.Moreover, the original power consumption of 10 kWh per ton has been replaced by steam engines, and thousands of tons of coal are needed every year.
3800吨硫酸原料，则由配套的4000吨硫酸车间提供。硫酸车间占地面积33×16平方米，员工定额 50人。每年需要4892吨硫铁矿，也专门配有一艘200吨级的运输船从万宁的山根硫铁矿运回。每年44万度电，需要转化成相应的蒸汽动力――测算消耗4000吨煤。另外每年还需要40万吨的工业用水。

The visitors watched the huge steel machinery running continuously, the pungent smell of sulfur was unbearable, piles of gray stones and lime soil were continuously thrown into the giant mouth of the steel, and finally became the "fertile field powder" that could increase production if it was applied.They can more or less understand that Tiandi will make compost and the like-after all, compost is also a kind of farmyard manure.But this kind of thing that can increase production with only stone powder is beyond their understanding.

Everyone in the group was shocked, thinking that the chiefs held the huge power and iron in the palm of their hands, and seized the opportunity of creation. They were not only in awe and awe, but also had greater expectations for the bright future of Lingao.I am more confident about the future of myself and my family.

But for Ji Situi, the current situation is not good at all.There are too many places that need chemical products for industrial upgrading, starting from the equipment manufacturing industry.Military industry, agriculture, medicine...Almost all of them put forward various requirements for the chemical industry, but so far these requirements are not met by many chemical industries. Even if they can be produced, most of them still have the problem of insufficient production capacity.

This aspect is firstly limited by materials. Chemical production equipment requires many corrosion-resistant materials and special steels. At present, their metallurgical industry basically cannot meet the requirements, and ceramics and glass have to be widely used as manufacturing materials for many chemical equipment.Although the corrosion resistance of these two materials is good, and the sources are also very wide, the mechanical properties and processability of the materials are limited.It can only be used to make some small equipment and parts as substitutes.This also makes most of Lingao's new chemical companies almost expand the laboratory production several times.

Moreover, the Ministry of Chemical Industry does not have enough manpower: chemical plants pollute a lot, and there are many work-related injuries. Hundreds of people are killed or injured every year due to various accidents.And it goes without saying that the appearance of the dead and injured is horrific—under the current level of medical treatment in Lingao, most of the injured in chemical accidents would not survive, and those who managed to recover were moderately disabled.

Although measures were taken to strictly block the news of the accident and provide generous remuneration, many naturalized people who knew the inside story were still reluctant to work in chemical factories, and had to assign contract slaves without personal freedom to work in chemical enterprises.If it hadn't been for the large number of contract slaves brought in by Operation Engine, his plan to expand the scale of employment would have been difficult to realize immediately.

Ji Situi was trapped by huge demand, poor equipment, untrained workers, frequent accidents, and intermittent supply of raw materials, all of which made him have gray hair.

After visiting the production line, let the customers of Tiandihui leave separately, Wu Nanhai and Ji Tuisi took the "city railway" to go back to Bairen City
Seeing Ji Siti's relaxed expression, Wu Nanhai took out a "Chuqing Limited Edition" and handed it over, taking the opportunity to say, "Old Ji, I heard that the production of ammonium bicarbonate is relatively simple, as long as there is anthracite, it will be easy to do. And it is more suitable for the acidic soil here than ammonium sulfate. Can you see if we can specialize in the next step? We also have a big gap in nitrogen fertilizer..."

"Old Wu, do you think we haven't thought about this? Back then, most of TG's small chemical fertilizers were ammonium bicarbonate projects. Now we have no problem with the supply of anthracite. But the problem came back in a circle," Ji Tuisi Light a cigar, and talk eloquently: "Our 800 tons of synthetic ammonia use Hou Debang's combined carbon method, which is common in small nitrogen fertilizer factories. Otherwise, where do you think the ammonium bicarbonate that is provided to you now comes from?"

The current 800-ton synthetic ammonia production project in the chemical plant uses the carbon-linking method invented by Hou Debang in 1958.The synthesis process uses anthracite as the raw material to produce semi-water gas, which, after removing hydrogen sulfide, enters the pressurized shift reaction system to obtain a mixed gas of nitrogen, hydrogen and carbon dioxide.The mixed gas enters the carbonization tower, where carbon dioxide reacts with ammonia water with a concentration of about 17% to form ammonium bicarbonate crystals, which are separated by a centrifuge to obtain ammonium bicarbonate products.

After removing carbon dioxide, the raw material gas enters the ammonia synthesis system to make ammonia water after further removing residual carbon dioxide and a small amount of carbon monoxide.

Ammonia can not only enter the carbonization tower to produce ammonium bicarbonate, but also be used as a raw material to manufacture other chemical products.

This joint production method can also produce a small amount of sulfuric acid at the same time, which is a production method with low energy consumption and high output.

Wu Nanhai was greatly disappointed: "So it's still a question of the scale of synthetic ammonia production."

"That's right." Ji Tuisi said, "Without synthetic ammonia, we must find a way to import saltpeter from the mainland in a stable way—this possibility is unlikely. unlikely to meet our needs; or establish a sea route for Chilean saltpeter across the Pacific now..."

"That's even more impossible." Wu Nanhai shook his head, "We still have to build mining sites ourselves."

"That's right, so there is only one last way left, which is to light up the technology tree of self-produced synthetic ammonia equipment as soon as possible and expand production capacity." Ji Tuisi said meaningfully, "Equipment manufacturing is still the foundation of everything."

"You're right." Wu Nanhai said, "I think everyone understands this truth. It should be mentioned more at the meeting."

Ji Tuisi smiled: "Let's not talk about the equipment problem. Let's talk about the 4000 tons of sulfuric acid supporting project in this factory. It is planned to use pyrite, which needs 5000 tons a year, but the mountain roots in Wanning County that we can mine now Pyrite, at most in history, has more than 1000 tons a year. It is not enough for the current sulfuric acid plant. Even if the Shanne Pyrite Mine immediately reaches the maximum production capacity in history next year, I don’t know the new gap of [-] tons. Where can I find..."

Wu Nanhai broke into a cold sweat when he heard this. If the sulfuric acid supporting facilities are not enough, wouldn't his [-] tons of ordinary calcium superphosphate per year be ruined!Quickly asked:

"Is there no other pyrite in Hainan?"

"Yes, there is, but mining and transportation are inconvenient, and the conditions are not as good as Yamane's: just dig it out at the seaside and pull it directly to the seaside with a rail car for loading." Ji Tuisi smoked a cigar, "The opinion of the planning institute is to expand Yamane sulfur first. The mining of iron ore, and the import of natural sulfur from Taiwan..."

Taiwan, like the Ryukyu Islands and the Japanese archipelago, has a large number of natural sulfur mines due to relatively active geological activities.It was already an important export commodity in the Qing Dynasty.

"It wouldn't be bad if a large amount of natural sulfur could be shipped in. We also have a great demand for sulfur in agriculture."

"It's mainly the relationship between transportation capacity and manpower. Speaking of Taiwan, Hualien has a large amount of serpentine. If it is to be mined and transported back on a large scale, it is much simpler to produce calcium magnesium phosphate fertilizer with the blast furnace method than superphosphate, and there is no need for matching. The sulfuric acid project..."

"Taiwan is really a land of geomantic omen."

……

The two talked all the way.Soon they will arrive at their stations.It was already three o'clock in the afternoon when Wu Nanhai returned to the office of the Council of Agriculture. He sat down and took out a black leather secret memo from the locked drawer, which he specially used to record some sensitive and important matters. Write a paragraph on it.
