What is a pressurisation tank?

What is a pressurisation tank? The question arises. We know, taken separately, what pressure and a tank are. But what about a mixture of the two? Whether you've answered this question by asking questions about hydraulic reservoirs, or are simply curious about everything mechanical, it's worth finding out. So we created this little topic. So, this is the place to find out why and how a pressurisation tank works!

First of all, what on earth is a pressurisation tank? You might ask.

A pressurisation tank, or pressure vessel, can take many forms and be adapted to many situations.

Basically, we can say that a tank of this type is a container designed to hold gases or other liquids at a pressure volume that is clearly different from the ambient pressure in the surrounding air.

This pressure differential makes it easier to store them and ensures that they retain a certain inertia, making them easier to store and move. And, of course, more safely!

Where do you find this type of tank?

Well, very simply, on a day-to-day basis - our gas bottles, for example. Pressurisation makes them easy to store and move.

Hydraulic tanks can also be affected. These tanks can be of any type, fuel, gas, etc. Injecting air into the upper part of the tank increases the pump's suction capacity. These capacities are increased without the need to increase the pump pressure, since the tank pressure itself is higher.

This also means that the pumps can be moved further away from the reservoir, as the pressure is higher internally. This ensures the safety of the site. What's more, it ensures clean air, since the air is higher in the tank than in the environment.

Tank pressurisation is often in the region of 0.2 bar, hence the use of a pressure regulator for compressed air.

We have seen the advantages of tank pressurisation and the many issues involved, including the storage and movement of often sensitive materials such as gas and fuel.

But how does this process work? Let's find out.

WHAT ARE THE INS AND OUTS OF THE PROCESS?

Having looked at the issues involved and the very principle of tank pressurisation, let's see how it works in practice.

The types of pressurised tanks are as varied as their uses. But there are some generalities. Apart from the fact that they are not made like any other tanks, but with specific materials (stainless steels, lighter composite materials), they must allow optimum storage. Finally, they must be relatively easy to move, given the large volumes that are sometimes stored.

Finally, as we have said, the intended use of the tanks will have a major impact on their design, and one or other of the formulas cannot be replicated for all storage drums!

As for the air that will pressurise the container, its volume must take into account the type of liquid or gas you choose. Depending on what you're going to use, it's easy to guess that the chemical mass of the product varies and that you can't introduce the same amount of air.

As for the air, it must be clean and dry. This means rigorous control of the compressor's air filters so as not to compromise the quality of the air inserted into the tank.

This last point is vital for the integrity of the materials contained in the tanks, particularly in view of the pollution contained in uncontrolled air that can corrupt the contents.
