Luo Dagang went to Shaozhou Mansion to see the tomb of his son Luo Feide, Feng Yunshan originally wanted to accompany him, but the recent affairs of the palace are really inseparable, and Luo Outline also wants to be quiet alone, so he has no choice but to let him.

The next day, Feng Yunshan, accompanied by Liu Shengbang and Wang Minyun, went to the newly built oil refinery at the foot of Xihua Mountain in the west of Guangzhou to check.

It just so happened that the weather was fine that day, so Feng Yunshan asked Wang Minyun to send someone to inform Xu Shou and go to the refinery to investigate.

Now Feng Yunshan is becoming more and more like a real prince. The inside wall of the car is made of steel plates produced by the First Iron and Steel Plant, and foreign guns cannot penetrate it to prevent someone from assassinating them.

These were all made up by the Ministry of Police and Liu Shengbang and other palace guards, Feng Yunshan felt awkward at first, but under Liu Shengbang's several requests, thinking that he was assassinated last time, he acquiesced, and over time, he became accustomed to traveling like this.

After four or five hours of travel, it was past noon when we arrived at a flat field next to the river bend where the refinery was located.

Xu Shou and a group of palace guards had already greeted him in front. Xu Shou stepped forward to salute and led Feng Yunshan, who had come out of the sedan chair, to several adobe houses half a mile away from the river.

"Holy King, this is the site where the refinery is going to be built." Xu Shouyu reported, and pointed to the open space by the river: "There, according to the Holy King's wishes, a wharf can be built to load and unload crude oil and refined refined oil, and when the cement arrives next month, construction can begin." ”

"And here, Holy King, please see, here is a row of two-story adobe houses, which serve as dormitories and resting places for the craftsmen and guards of the oil refinery."

Following Xu Shou's introduction, Feng Yunshan saw a row of houses, there were twenty or thirty in a row, so he nodded and said, "Xuecun, the house is well built." In this way, not only dormitories can be built here, but also dormitories, latrines, bathhouses, recreational rooms, etc., and this place should be built as a home. Let the craftsmen here stay here with peace of mind and refine oil for the holy country. ”

Xu Shou nodded.

"Let's go, take this king to see the oil refining test device you built." Feng Yunshan was a little looking forward to it, he wanted to see what kind of miniature oil refining unit Xu Shou could lead the craftsmen to build according to his design sketch.

Xu Shou hurriedly led the way in front, walked into the back of a row of trees, and leaked out of an empty field.

Feng Yunshan noticed that in the middle of the venue, there were already many iron cans and iron cages. And this site is surrounded by trees.

"Snow Chuen, your design is very good. The oil refining site is located in the woods, well, it is difficult for outsiders to find out. Feng Yunshan saw that this piece was obviously shoveling some trees in the middle of a forest, leveling the ground in the middle, and then building an oil refining test unit, which was very appreciative.

Xu Shou scratched his head, and was a little embarrassed by Feng Yunshan's praise.

Feng Yunshan saw that he was restrained, so he diverted from the conversation and said, "Xuecun, the test device for oil refining, how did you build it?" ”

Speaking of the test device, Xu Shou was interested: "Holy King, the more your subordinates study your design drawings, the more they are impressed. This little oil refining is endlessly mysterious. In many places, the subordinates haven't figured it out yet, but, according to the drawings, they finally came up with it. ”

While talking, the two walked forward, and soon, they arrived at an open position in the middle of the woods, and saw several iron cans and iron towers placed there densely and sparsely, tall and low, and there were steel pipes and copper pipes connecting the tanks and the tanks, which were densely packed to make people have a headache at a glance.

However, for Feng Yunshan, it is so familiar.

In his previous life, he had worked in the refinery for many years, and he had seen a much more complex oil refining unit than this, not to mention this simplest atmospheric and vacuum distillation unit? What's more, it is also a small and medium-sized test device. What can be simplified, what can be saved, have been eliminated.

For this oil refining test device, Feng Yunshan uses a simplified version of the atmospheric and vacuum oil refining process. Originally, he wanted to use the soil refining process, because it was the simplest, but since he knew the atmospheric and vacuum distillation process very well, why did he go back and use the most primitive earth pot refining process?

The so-called local oil refining, in fact, in later generations, is not uncommon, Feng Yunshan has seen those small workshops, secretly using low-cost soil oil refining, using waste tires and plastics, through multiple cracking, refined into fuel.

At that time, they used a simple iron tank welded of ordinary carbon steel, adding a pool on top of the iron tank, putting the disc pipe into the pool for cooling, heating and distilling the cracked oil and gas in the iron tank, and then cooling the oil and gas into oil through the disc pipe; A steam drum can also be installed above the disc pipe to collect gases that cannot be cooled into oil, that is, gases such as liquefied gas.

Feng Yunshan adopts a simplified version of atmospheric distillation that combines the soil refining process and the atmospheric and vacuum distillation process.

Because it was his own design, Feng Yunshan knew it well at a glance, and he insisted on setting up the largest iron tank in the middle, and said: "This is the atmospheric distillation tower, which is the most important core object in the entire oil refining unit. Xuecun, what do you do in this atmospheric distillation column? ”

"Yu Shengwang, this iron tower, my subordinates took the drawings you took, went to the No. 1 Iron and Steel Factory, found the best craftsmen to knead a model out of paraffin, and then sealed the paraffin model tower with fine clay around it. Then let the steel mill use the best molten steel and flush it into the sealing model. The paraffin wax was driven away and turned into fly ash, and the molten steel occupied the original paraffin position, forming this iron tower. Xu Shou explained the practice of this atmospheric distillation column.

"Well, you're doing a good job. It is equivalent to one-time casting molding, this king comes to see, hey, the thickness is okay, thicker than the king requires, not bad. Feng Yunshan touched the opening of the atmospheric tower and said, "Do other iron cans and iron pipes do the same?" ”

Xu Shou nodded.

"It's all cast? The strength is enough, but I am afraid that it will crack when it is heated and cold, and the sealing will become a problem. By the way, Snow Village, these short pipes of yours are all made of cast copper. This copper tube is tougher and less prone to cracking. Feng Yunshan demanded.

Xu Shou hurriedly recorded it.

"Well, this atmospheric tower has a total of 23 layers of trays, which is less than half of the original real atmospheric tower, and the openings for oil extraction are still four, which has not changed; There are also two circulating extraction lines, but this is one less than the original atmospheric tower, what about the pump? Feng Yunshan muttered, turned his head and saw that there were two devices similar to waterwheels next to him, hanging there vertically with iron chains.

Feng Yunshan understood at a glance. Can't help but be happy! But it turned out that Xu Shou and the others really couldn't make a pump, so they used a method similar to a waterwheel to manually drive the oil truck with an iron chain to lift the hot oil to the top of the tower and then flow into the tower.

Who said that people of this era lack modern scientific knowledge? Feng Yunshan found out that they were actually very smart, would use alternative methods, and solved the problem perfectly.

However, there are still limitations, in this set of refining test equipment is possible, the production volume is not large, if you want to replace it with a large refining unit, this will definitely not work. Feng Yunshan had a solution, a steam engine, and a water pump, and this oil pump could be developed.

"Not bad! The installation of these equipment and the connection of pipes are all in accordance with the design of this king. This is the collection tank that leads from the top of the tower, which you will call the gasoline tank in the future, and the oil in it will be called gasoline; The two collection tanks in the middle, which are drawn out slightly above, are called kerosene tanks, which store kerosene, and the one below is called diesel tanks, and the oil products inside are called diesel. At the bottom, there is a black heavy oil, which can be recycled, and after many refining, it can be used to make a fire and heat the coil of the oil. ”

"The most dangerous thing is to heat the coil with oil, if it leaks, it will catch fire or even explode! Xue Chuen, the coil you are using now, this king thinks it is still not very reliable. Don't be afraid of the cost here, all use copper pipes, cast as a whole, use thicker pipe walls, and replace this coil! Feng Yunshan frowned when he saw the coil that needed to be heated into the oil.

Xu Shou hung his head and hurriedly agreed.

Feng Yunshan was also afraid that the cast iron pipe would be easy to crack when heated. It's all crude oil, and there's a burning fire down there, so if it leaks, it's no joke.

Feng Yunshan also knew that it was not appropriate to use a blazing fire to roast, but to heat the crude oil in the coil to nearly 200 degrees without fire, there was no other way in this era.

Originally, Feng Yunshan wanted to design the form of a boiler, but he couldn't fathom the oil of this crude oil, in case it was heated to the ignition point one day, and it came into contact with the air, it burned directly. In addition to such a large boiler, the position has to be relatively high, which is really troublesome, it is better to use the coil directly, and it can also avoid contact with the air.

If steel can be welded one day, it will be possible to manufacture high-pressure pressure pipes and vessels, so that high-temperature and high-pressure steam can be produced at more than 200 degrees, but it is still impossible to do it today.

"Well, overall, Snow Chuen, you're doing a great job! Then replace the connecting short pipes and heating coils with copper pipes, as well as the connections between the tower hole and several oil tanks, seal them with soft soil, and water them with molten iron outside, you can use them with confidence! Very good, this king is looking forward to the early commissioning of this oil refining unit to refine gasoline, diesel and kerosene. ”

"The subordinates will live up to the trust of the Holy King!" Xu Shou led a group of craftsmen from the refinery to lead the order in unison.
