The End of the World: I built the Supreme Shelter one year in advance

The core equipment of a fuel-based refinery is a distillation device.

After the crude oil is injected into the distillation device, the preheated and desalted crude oil can be separated by the difference in boiling points and the characteristics of the higher temperature at the bottom of the distillation tower.

A distillation device can divide crude oil into light distillate oils, such as liquefied petroleum gas, gasoline, and naphtha;

Middle distillate oil, kerosene, diesel;

Heavy distillate oil and residue oil, heavy fuel oil, lubricating oil, wax, asphalt and other products.

After preliminary separation of crude oil.

These products need to be sent to the catalytic device, catalytic cracking device, catalytic reforming device, and catalytic hydrogenation device for finishing to improve product quality.

But Sun Renqing's small oil refinery can only process 100 tons of crude oil per day, so he only purchased fuel finishing processing equipment.

As for other industrial raw materials separated by distillation equipment, Sun Renqing directly sold them to large oil refineries that are capable of finishing.

If conditions permit.

Xu Zhengyang also wanted to get it in one step and build a comprehensive refinery in his own shelter that can handle and produce all oil products.

However, due to the limited area of ​​the shelter, Xu Zhengyang could only complete the current task first and then develop it later.

...

More than an hour later.

With the overall coordination of Dabai, the three engineering robots have removed all the core equipment of the refinery.

But these devices are a bit large.

Xu Zhengyang traveled back and forth between Shandong Province and Baicheng six times in two days, and then he moved all the equipment back to his shelter.

With the last unloading.

Dabai coordinated and manipulated all the engineering robots to reinstall the equipment in the refinery in his own shelter.

A series of system subtitles finally appeared in front of Xu Zhengyang's eyes:

[Main mission: Refinery (completed)]

[Reward: Dimensional Space Bag Upgrade Device IV]

...

【Dimensional Space Bag Upgrade Device IV】

[Effect: Increase the space of the dimensional space bag to a spherical space with a diameter of 100 meters]

(Note: It will take effect after putting it in the dimensional space bag)

"ox!"

After seeing the level 4 dimensional space bag upgrade device, Xu Zhengyang couldn't help but exclaim.

The spherical space with a diameter of 100 meters has a volume of about 523,599 cubic meters!

Feeling the upgraded dimensional space bag, Xu Zhengyang sighed, "If my dimensional space bag had such a large space before,

At most, I can move all the equipment from that refinery back in two times. How can I waste so much time? ”

While talking.

Xu Zhengyang first used the optical camouflage function of the shelter to hide the refinery built next to the thermal power plant.

Then he opened his task list to view the latest main task:

[Main task: Water Resources Treatment Center (in progress)]

[In the end of the world, clean water sources are an absolute necessity for survival. Even deep groundwater may be contaminated.

For your drinking water safety, please build a water treatment center in the shelter]

【Mission Objective: Build a water treatment center in a shelter

(The water plant requires an area of ​​no less than 500 square meters;

The quality of domestic water is required to be pure water, with a water output of no less than 100 tons/day; the quality of industrial water is required to be municipal tap water, with a water output of no less than 1,000 tons/day]

[Task Reward: Building Special Effects·No Drops]

After reading the details of the mission, Xu Zhengyang immediately said to Dabai, "Dabai, there is a room of 500 square meters in the shelter.

Then make another floor of waterproofing with the highest standard in the room! ”

"Okay master."

Dabai agreed and the back foot engineering robot had already started working.

*

After Dabai started working, Xu Zhengyang was not idle either. He immediately went to the computer to search for some information about the water plant.

Thanks to the strong advantages of my country's entire industrial chain.

Various equipment and consumables for water resource treatment are very easy to buy. Xu Zhengyang doesn’t need to buy online. He can buy all the equipment he needs directly in Baicheng.

So while the engineering robot is still working in the shelter.

Xu Zhengyang immediately drove out and purchased various consumables and equipment for water treatment.

...

Tap water treatment is already a very mature industry, so all kinds of equipment and consumables are everywhere, and the parameters are also rolled up.

Under Dabai's screening.

Xu Zhengyang soon bought various equipment and consumables needed to build a tap water plant in the Machinery City, and solved the problem of industrial water use.

...

As for the pure water required for this task, the water used in the domestic task.

Its equipment is easy to buy, but some consumables are very troublesome.

The core consumable for producing pure water is the RO membrane, also known as the reverse osmosis membrane.

No mistakes, one song, one content, one in 6, one book, one bar, one reading!

The way water flows is generally from low concentration to high concentration, but once the feed water is pressurized, the water will flow from high concentration to low concentration, which is the principle of reverse osmosis.

The pore size of the RO film is one millionth of a hair strand (0.0001 microns).

That's why.

As long as an RO membrane is added to the filtration equipment, only water molecules and some mineral ions can pass through, reaching the standard of pure water!

An industrial-grade RO membrane can filter nearly one million liters of pure water.

But this thing is a consumable after all, and there will always be a time to use it up.

After the end of the world, Xu Zhengyang may not be able to find this thing, so for the sake of his own drinking water safety.

Xu Zhengyang simply bought 100,000 rolls of industrial-grade RO film at one time!

Hearing this number, the boss was stunned and asked Xu Zhengyang in disbelief, saying, "How many...?"

"Hundreds of thousands."

Xu Zhengyang said, cutting his phone directly to the online banking app and saying to the boss, "I will pay the deposit now, you can ship the goods quickly!

As long as the goods arrive, you will be given the final payment immediately! ”

"Okay, okay!"

The boss was so excited that he was almost unable to stop talking. He was afraid that Xu Zhengyang would regret it, so he hurriedly said, "I'll contact the manufacturer to deliver the goods now and speed up the delivery!"

...

Buy what you need.

Xu Zhengyang didn't have the intention to stay here too much, and drove his car back to the shelter.

When passing through the high-tech zone.

The several large business districts here were originally the most prosperous and lively places in Baicheng.

However, after two zombies in a short period of time, the popularity disappeared instantly, even in broad daylight.

There were no few people on the street, and they were deserted.

When Xu Zhengyang was driving through Gaoxing District, he suddenly noticed a completely unconcealed malicious intention to scan himself!

at the same time.

A string of system subtitles appeared in front of Xu Zhengyang's eyes:

【Breaking time-limited task: Pretender (in progress)】

[A disguiser appears near your shelter. It can deceive human senses and mix into the gathering point of human beings to spread blood plague!

To stop the disguiser from creating new corpses around your shelter, get it fixed immediately! 】

【Task Target: Kill the Pretender】

【Task Limit Time: 23:59:58 seconds】

【Task Reward: Power of Disguise】

Thanks to [SCP-862] 588 reading coins for rewards!

Thank you [Book Friend 140218091139827] for the reward of 100 Qidian coins!

Thank you for the rewards from the two bosses, the bosses are generous!

There was an unsupported social event tonight, and I came back a little late.

I will update three chapters first, and the remaining two chapters will be posted after I finish writing them. The time may be a bit late. I suggest you read them tomorrow
