Apocalypse: I built the Supreme Sanctuary a year in advance

Chapter 88 Pretender

The core equipment of a fuel-fired refinery is the distillation unit.

After the crude oil is injected into the distillation unit, the preheated and desalted crude oil can be used to separate the substances by taking advantage of the difference in boiling points and the higher temperature at the bottom of the distillation tower.

The distillation unit can separate crude oil into light distillates, such as liquefied petroleum gas, gasoline, and naphtha;

Middle distillates, kerosene, diesel;
Heavy distillates and residual oil, heavy fuel oil, lubricating oil, wax, asphalt and other different products.

After the initial separation of crude oil.

These products need to be sent to the catalytic unit, catalytic cracking unit, catalytic reforming unit, and catalytic hydrogenation unit for fine processing to improve product quality.

However, Sun Renqing's small refinery could only process a maximum of 100 tons of crude oil a day, so he only purchased fuel refining processing equipment.

As for other industrial raw materials separated by the distillation unit, Sun Renqing directly sells them at low prices to large refineries capable of fine processing.

If conditions permit.

Xu Zhengyang also wanted to do it in one go and build a comprehensive refinery directly in his own shelter that could process and produce all petroleum products.

However, due to the limited area of the shelter, Xu Zhengyang could only complete the current task first and then plan for development later.

……

More than an hour later.

Under the coordination of Dabai, the three engineering robots have dismantled the core equipment of the refinery.

But these devices are a bit bulky.

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

With the final unloading.

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

Finally, a series of system subtitles appeared in front of Xu Zhengyang:
[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 when placed in the dimensional space bag)
"Cattle!"

After seeing the fourth-level dimensional space bag upgrade device, Xu Zhengyang couldn't help but exclaimed.

A spherical space with a diameter of one hundred meters has a volume of approximately 523599 cubic meters!
Feeling the upgraded dimensional space bag, Xu Zhengyang said with emotion, "If only my dimensional space bag had such a large space before,

I can move all the equipment back to that refinery in two moves at most, so why 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 and checked the latest main task:

[Main Mission: Water Resources Treatment Center (In Progress)]

[In the end times, clean water is an absolute necessity for survival. Even deep groundwater may be polluted.

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

[Mission Objective: Build a water resource treatment center in the shelter
(The water plant area is required to be 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 1000 tons/day.

[Task Reward: Building Special Effects: Watertight]

After reading the mission details, Xu Zhengyang immediately said to Dabai, "Dabai, separate a 500-square-meter room in the shelter.

Then do another layer of waterproofing to the highest standards inside the room!"

"Good host."

As soon as Dabai agreed, the engineering robot started working.

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

Benefited from the strong advantages of my country's entire industrial chain.

The various equipment and consumables for water resource treatment were so easy to buy that Xu Zhengyang didn't even need to shop online; he could buy all the equipment he needed directly in Baicheng. So, while the engineering robots were still inside the shelter, they began working.

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

……

Tap water treatment is already a fairly mature industry, so various equipment and consumables are everywhere, and the parameters are also skyrocketing.

Under Dabai's screening.

Xu Zhengyang quickly bought all the equipment and consumables needed to build a water plant in the Machinery City, solving the industrial water part of the task.

……

As for the pure water required for the domestic water part of this mission.

The equipment is easy to buy, but some of the consumables are troublesome.

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

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

The pore size of the RO membrane is one millionth the size of a human hair (0.0001 micron).

Therefore.

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 it will eventually run out.

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 membranes at one time!
Hearing this number, the boss was stunned. He asked Xu Zhengyang in disbelief, "How much more?"

"One hundred thousand."

Xu Zhengyang said, and directly switched his phone to the online banking app, and said to his boss, "I will pay the deposit now, please ship it quickly!

As soon as the goods arrive, we will give you the final payment immediately!"

"Good good!"

The boss was so excited that he almost couldn't close his mouth when he heard this. Fearing that Xu Zhengyang would change his mind, he hurriedly said, "I will contact the manufacturer to deliver the goods immediately, and expedite the delivery!"

……

Buy what you need.

Xu Zhengyang didn't want to stay here for too long, so he drove his car back to the shelter.

When passing through the High-tech Zone.

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

But after two zombie incidents in the High-tech Zone in a short period of time, its popularity instantly disappeared, even in broad daylight.

There were few people on the streets, it was deserted.

Just as Xu Zhengyang was driving past the Happy Zone, he suddenly felt a completely undisguised malice sweeping towards him!
at the same time.

A series of system subtitles appeared in front of Xu Zhengyang:
[Sudden Limited Time Mission: Disguiser (In Progress)]

[A pretender has appeared near your shelter. It can deceive human senses, blend into human gathering places and spread the blood plague!
To prevent the Pretender from creating new zombie hordes around your shelter, please eliminate them immediately! 】

[Mission Objective: Kill the Impostor]

[Mission time limit: 23 hours, 59 minutes, 58 seconds]

[Mission Reward: Power of Disguise]

　Thanks to [SCP-862] for the reward of 588 reading coins!

　　Thanks to [book friend 140218091139827] for the 100 starting coin reward!

　　Thank you both bosses for the tip, you are so generous!
　　I had an unavoidable social engagement tonight, so I got home a little late.

　　I will update three chapters first, and will post the remaining two chapters after I finish writing them. It may be a little late, so I suggest you read it tomorrow.
