Cha Yingjie said! "Bu Zongjin is six. We call it electrolyte. The caustic soda on the surface is as old as the public. It is old and has a lot of impurities. It needs to be separated and processed again."
"Look out. Chlorine gas!" Ji Sidui patted Xu Yingjie's shoulder.
"What, what." Bai Yu wanted to get closer and take a look.
Be careful and don't move. "Xu Yingjie was a little excited. He was not thinking that chlorine can disinfect and purify the environment. It can be used for things like hydrochloric acid, and then it can be used as a "toxic gas"
Although chlorine gas is common, it was the first poisonous gas used in actual combat in the history of modern warfare. It was said to have achieved outstanding results during World War I. There are countless dead souls. Moreover, chlorine is easy to produce and can be called a super killer in this time and space. No matter you are a Manchurian white armored soldier, Guan Ning's cavalry, an imperial family member or a Cromwellian armored soldier, there is only one "death" you encounter.
Currently, the traveler industry cannot manufacture gas pressure vessels, so storing chlorine gas is impossible. But Xu Yingjie knew that there were many perverts in the weapons research group, and they might be able to bring out some evil moths.
This yellow-green gas rose in the glass tube, and everyone present held their breath. At this time, a small blade fan installed in another glass tube suddenly started running, which indicated that hydrogen gas was also released from another colorless electrolyte product.
"Everyone should pay attention." Ji Sidui began to educate the workers on safety: "This yellow gas is called chlorine gas. It is poisonous."
Watching Ji Sidui explain to a group of indigenous workers who seemed to understand but didn't understand what chlorine gas was, what hydrogen gas was, and how to prevent poisoning and explosions, Bai Yu thought to herself that it would be too dangerous for me to come to this chemical plant in the future.
The produced hydrogen is fed to the only modern device in the facility: the hydrochloric acid reactor. Hydrogen is introduced into the reactor for combustion, and then curtain gas is introduced to generate hydrogen chloride gas. After cooling, it is absorbed by water and becomes hydrochloric acid.
this. The reaction is very dangerous. If the chlorine content in hydrogen is too high, it will explode directly. The solution is to strictly control the amount of chlorine entering during the reaction process, so that the toxic chlorine is surrounded by excess hydrogen, allowing the chlorine to fully react and preventing air pollution. and possible hybrid explosions.
Because of the great danger, Ji Situi never considered indigenous equipment from the beginning, but directly purchased equipment from modern time and space.
Only a part of the chlorine gas is consumed in making hydrochloric acid, and the rest is passed into the reaction tower on the side, which has been filled with dried slaked lime in layers. The chlorine gas is absorbed by the slaked lime to form calcium hypochlorite, which is more familiar to everyone as bleaching powder.
As the most common and effective disinfectant, the successful mass production of bleaching powder means that Chuanchuan Group has reached a new peak in disease prevention and fatigue prevention, which is of great significance to Chuanchuan Group's bases on both sides of the Wenlan River where people are extremely dense. When the army goes on an expedition, it no longer has to worry about the sanitation of drinking water along the way.
It is difficult for slaked lime to absorb chlorine completely. It will take away part of the chlorine gas more or less in the waste. In order to better utilize the chlorine gas and improve the air environment at the same time, it is generally necessary to adopt the last waste gas absorption process.
The waste gas sent from the absorption tower is connected to the absorption return pipe, and the cylinder is filled with lime milk prepared from slaked lime. The chlorine in the exhaust gas is absorbed by lime milk to generate calcium chlorate and calcium chloride.
After the lime milk is saturated with chlorine, it is pumped into a concentration pot, heated and then cooled to crystallize calcium chlorate. Calcium chlorate can be used as a herbicide. The calcium perchlorate liquid is extracted and concentrated by heating. You can get calcium chloride. Basically achieving zero emission of chlorine gas.
As for the electrolyte that continuously flows out during electrolysis, it already contains probably old caustic soda. However, it contains higher amounts of sodium chloride. Such caustic soda solution cannot be used and must be concentrated.
The equipment used by Ji Situi for concentration is a large pot, which uses firewood to ignite coal to directly heat and concentrate. The strong smell caused everyone present who was not wearing safety glasses to flee.
"Is it too polluting to be boiled with such an open mouth?" Bai Yu said.
"Yes, but don't we have a steamer? It's a waste of coal!" Ji Sidui was wearing a chemical protective mask. He said loudly, "We will wait until the machinery factory can provide us with supporting equipment."
.
After boiling for a while. Under the lye, crystals precipitated from the bottom of the pot, accumulating more and more.
.
"Bai Yu, grab a spoon and scoop it out quickly! Be careful not to bring out the lye."
Bai Yu quickly took the special wooden spoon and stood by the pot to scrape out the crystals from the bottom of the pot.
"Pay attention to safety." Ji Sidui looked at him nervously. This pot was made from the roasted pig brought from Goujiazhuang at that time and has a large diameter. If you don't pay attention and fall down, you'll be dead.
.
Bai Yu carefully took out the crystals. The steam filling the pot felt pungent even while wearing a protective mask.
"Is this salt?" he asked.
"Yes, it's real salt!"
The taken out refined salt is sent to the salt drying board, washed several times with dilute alkali solution, and then rinsed with saturated refined salt water. What is left is snow-white crystals. The sodium chloride purity of this salt is as high as Gu or above. It can be used to prepare physiological saline for medical infusion.
The electrolyte from which the salt has precipitated is continued to be heated and concentrated until the concentration of the alkali solution reaches about 50%, and it can be used in chemical industry. product. Of course, you can continue to concentrate and dry it into a solid, but this consumes too much coal and is not cost-effective for time travel.
The successful manufacture of sulfuric acid, hydrochloric acid and caustic soda gave great confidence to the Works Energy Commission, Wang Luobin, Zhan Wuya and others. Whenever I have time, I come to these two simple workshops to see the equipment that is made using local methods.
Although these two sets of devices are simple. The benefits brought by it are immeasurable. According to Ji Situi's calculations, under the condition of ensuring the supply of raw materials and energy, the contact method sulfuric acid workshop is equipped with workers in three shifts! Ming, the annual start-up time is 1,000 tons of concentrated sulfuric acid per day, which can be increased to 1,000 tons per day when necessary; the salt electrolysis workshop is equipped with workers in three shifts. Calculating the annual start of construction, it can produce 6 tons of caustic soda, 1 tons of bleaching powder, 6 tons of calcium chlorate stew, and 6 tons of calcium chloride per year. Refined salt, many tons of sodium chloride, and stewed with king hydrochloric acid.
The output was minuscule by modern standards, but that was not the case for the Planning Commission, which not so long ago dispensed any chemical on a milliliter-by-gram basis. The commissioning of these two workshops was a windfall.
Even Shi Niaoren came. Seeing the high-purity sodium chloride prepared by Ji Sihui for him, Shi Niao Ren was so happy that he couldn't even close his mouth. It could solve a big problem! The physiological water for infusion and injection is too small to be taken after six doses, not to mention it is a good thing that the Ministry of Health is looking forward to. As for crude calcium chloride, it is refined by pharmaceutical factories and made into calcium chloride injection, which can treat tetany caused by low blood calcium, intestinal colic, ureteral colic, taro measles, exudative edema, and itching Sexual skin diseases.
It is used to treat vitamin deficiency rickets, rickets, and calcium salt supplementation for pregnant and lactating women. Substantially improve the physical quality of the people in this time and space.
With enough hydrochloric acid, the glucose manufacturing in the pharmaceutical factory plan can also be put on the construction schedule. Shi Niaoren immediately contacted Wu Nanhai and asked him to quickly come up with starch raw materials. Together, they could set up a glucose workshop immediately.
As for Wu Nanhai. He was overjoyed to suddenly get a herbicide that he had never expected, and immediately asked that all the related production be allocated to him for use. He also asked with concern when he would be given sulfuric acid massage. He can cooperate with hybrid rice to release a high-yield satellite.
Even people from the Ministry of Light Industry came to ask how much quota of caustic soda and sulfuric acid they could give them. With these two things, they would be able to provide white paper, not to mention soap. However, the Ministry of Chemical Industry and the Ministry of Light Industry must cooperate in making soap. Originally, the Ministry of Chemical Industry should obtain glycerin through the process of making soap.
It's like a snowball. Once a technical bottleneck is broken through. Many production areas that had been stuck suddenly started to move. The number of products that could be produced increased at once, and the scale of production capacity also expanded.
The military department also responded quickly, with Xi Asia calling on the same day. The Ministry of Chemical Industry is required to seriously consider the military value and use of chlorine as a weapon.
It was impossible to release chlorine gas directly, so Xu Yingjie and several people from the weapons research team studied it. Prescribe a kind of chlorine mine: put a bag of calcium hypochlorite powder, that is, bleaching powder, under the can of hydrochloric acid, and then tie it to a cartridge filled with guncotton. The two substances are blown into a mist through an explosion and mixed together. Together. As for the effect, everyone agreed that if you want to use it, it is best to detonate multiple bombs at the same time.
Some people have also proposed that poison gas shells can be made. The principle is the same as above, and the structure can be improved so that it can withstand the shooting of howitzers.
"It is not recommended to use it." Xu Yingjie could not imagine who could run around with many hydrochloric acid cans on the battlefield.
"In my opinion, we should rely on these poison gas shells and poison gas mines," Lin Shenhe of the artillery research team made concluding remarks. "It's better to make some glass bottles with hydrochloric acid in them, and then use them as grenades to throw them out."
The response from the crowd was great. Praise poured in from all departments. But as the head of the chemical industry department, Ji Sixui was not happy at all. Behind this series of dazzling product catalogs and production figures lies high energy consumption and extremely unstable production conditions.
A salt electrolysis workshop consumes tons of salt, stewed quicklime, blunt hydrochloric acid, tons of coal, and tens of thousands of kilowatt hours of direct current every year. water! Joint stew. This is an extremely objective consumption of materials and energy. Especially electricity and industrial water. The installed capacity of Bobu Power Station was originally only Yin Zhang... Just one electrolysis workshop consumes almost one-tenth of the power station's annual electricity. Insufficient power has actually become an important obstacle to the electrolysis salt workshop. The workshop, which was originally scheduled to start at the end of last year, has been pending. It was not until recently that the second phase of the Bairentan Hydropower Station was successfully expanded. A boiler there was moved to the Bobu Power Station, and the installed capacity of Bobu was doubled before it was officially put into operation.
Ji Si's plan is to wait until the manufacturing capacity of the machinery department is improved to a higher level, and then gradually replace the current equipment that is too crude. Such high-energy-consuming and high-pollution production is really not the future direction.
Another disadvantage of the local method is that after it was put into actual operation, many problems that were not mentioned in the construction brochure were exposed one after another.
The most typical one is the sulfuric acid workshop. Since the start of the operation, there have been many problems, big and small. The most serious one is that the conversion rate is low and cannot reach the cutting edge. As a result, the concentration of some sulfuric acids is too low, only 5%, and it must be re-blended. in order to reach factory standards. The outlet of the blower contains acid, which is scattered everywhere, causing serious corrosion on the ground; the exhaust smoke from the white smoke outlet contains a large amount of acid, and when it encounters humid air, it immediately turns into acid rain. All temporary factories and sheds around Yanbai were eroded and destroyed. Several workers suffered mild acid burns. Was taken to the hospital.
Ji Sixui and Xu Yingjie, as well as mechanical and construction technicians, made six consecutive modifications to the entire system. Even the absorption tower was disassembled and repacked several times. A pebble dust collector was added to the converter; coke was added to the air outlet as an absorbent; acid foam-removing tiles were added to the top of the absorption tower, and coke was added. ,, I even had a meeting to discuss and read books by myself. Fortunately, the big library is rich in information, and I found solutions to various problems one by one. It took a month of back and forth to stabilize production.
The network of the sulfuric acid workshop is stable, and there have been several small-scale accidents in the electrolysis workshop. The most outrageous thing is that someone actually took a fancy to hydrogen and designed and manufactured a balloon by himself. It was said that this was to make material preparations for future balloon observation troops, and they had to fill the workshop with hydrogen. But this person was wearing chemical fiber clothes and touched it immediately. He suffered second-degree burns all over his body and was rushed to the hospital for treatment. The entire electrolysis workshop was paralyzed for ten hours. Ji Si was so angry that he still surrounded the workshop with a bamboo fence. Hang a skull and crossbones hazard sign. No one is allowed to come in or out at will.
When Shi Niaoren returned from visiting the Bobu Chemical Factory, he discussed with the Planning Commission and the Ministry of Chemical Industry the supply of several urgently needed materials for the pharmaceutical factory. Then he went to the dormitory area of Cibairen City and took samples before returning. General Hospital.
"Touch it, touch it"
Shi Niaoren hummed "Eighteen Touches" and walked into Bairen General Hospital carrying several bags of stool. Ye Yuming, who was passing by, murmured in surprise: "Has this guy gone crazy looking at shit all day long?"
The real reason is certainly not the case! Sitting in his "first medical testing center in this time and space", Shi Niaoren confidently crossed his legs and piled a pile of poop sample cans with a smug smile. The successful start-up of the Ministry of Chemical Industry made his enthusiasm for the pharmaceutical factory, which had gradually cooled down, rekindle and increase his motivation, thinking about what other drugs he could make. This is better than ten years of hard training in internal skills. There is someone in the Time Travel Group! ! ~!
