How many adsorbers are there in the purification system of air separation equipment?

At the installation site of the air separation plant, we may see a variety of operation methods. We may be a little surprised when we first see it. We may get used to it if we see it many times. However, many accidents are caused by our negligence and carelessness. The following are some common sense of safe construction, hoping to be helpful to everyone: 1. Workers must wear safety helmets correctly when entering the construction site, because the construction site is often chaotic. Some equipment installation site, several construction teams are constructing at the same time, it is impossible to completely guarantee that there is no falling objects. 2. Use personal protective equipment correctly, and seriously implement safety protection measures. Safety belts must be fastened when constructing on high places, cliffs and steep slopes without protective facilities. 3. It is forbidden to climb the scaffold, safety protection facilities, etc. It is strictly prohibited to take the ele...

What are the signs of excessive carbon dioxide and water in the air after the molecular sieve adsorber of the air separation equipment? What is the reason?

What is the principle of the deep cooling method of air separation?

What are the reasons why the main cooling liquid level of the air separation equipment is not high and how to solve it?

According to the different ways in which refrigeration causes low temperatures, what are the three types of refrigeration capacity of air separation equipment?

Why is the pressure in the lower tower of the air separation equipment higher than that in the upper tower?

The expansion air volume entering the upper tower increases, and the reflux ratio of the distillation section decreases correspondingly. In order to achieve the required purity of nitrogen products, more tower plates need to be set. When the reflux ratio is reduced to countless Tower plates needed to be set to make the purity of nitrogen reach the required value, then the reflux ratio is called the minimum reflux ratio. The expansion air volume entering the upper tower is first limited by the minimum reflux ratio. The closer the reflux ratio is to the minimum reflux ratio, the faster the number of tower plates needed to ensure the product purity increases, which will lead to the increase of investment, the increase of tower plate resistance, the increase of Operation pressure and the increase of energy consumption. Therefore, the reflux ratio after the inflated air enters the tower should be larger than the minimum reflux ratio. When the purity of nitrogen is required to be low, the...
