Why is it suitable for large and medium-sized air separation plants to adopt full low voltage process?

Reducing the working pressure of the air separation plant can reduce the unit energy consumption of the product. The working pressure of all low press

What problems should be paid attention to when installing and using the spring tube pressure gauge?

Pay attention to when choosing pressure gauge:1) determine the range of pressure gauge. When the tested pressure is relatively stable, make 1/3 of the

What are the common faults of temperature measuring instrument?

The common failure of thermocouple thermometer is that the indicating value is low, or it stops at zero. This is because of the problem caused by ther

What is the minimum work in the separation process, and how to save energy in the rectification separation process?

Air is a mixed gas, and the gas separation process cannot be carried out spontaneously. In order to realize the separation of oxygen and nitrogen, wor

What is the influence of insufficient processing air volume on the rectification working condition?

When the air volume decreases, both the rising steam volume and the recirculation fluid volume in the tower decrease, but the recirculation ratio can

How is the purity of the oxygen generator product expressed?

In the process of production, indicators such as the purity of oxygen products is not less than 99.5%, the purity of nitrogen is not less than 99.99%,

What are the requirements for the installation of instrument detection pipelines?

All instrument pipelines and pipe fittings used for oxygen passage should be strictly degreased with carbon tetrachate or alcohol before installation.

What are the characteristics of parallel operation of two centrifugal compressors? What problems should be paid attention to when operating?

For workshops with multiple sets of air separation devices, several centrifugal compressors were often used to work in parallel in the past. Some air

Why is there both liquid nitrogen and gas nitrogen on the top of the air separation tower?

In boiling water when we can see, at atmospheric pressure, temperature to 100 ℃, water began to boil. But water not all at once into steam, but with t

Apr 08, 2013

Why can gas nitrogen be used to cool liquid nitrogen in liquid nitrogen supercooler?

The liquid nitrogen supercooler uses the low temperature gas nitrogen from the upper tower to cool the liquid nitrogen from the lower tower, so as to

Apr 08, 2013

As for the hollow air cooling of the medium pressure oxygen generator, part of it will be liquefied when it is-150℃. Why is it still gas when it is cold to-171℃ in the low pressure oxygen generator?

The liquefaction temperature of gas is not only related to the type of gas, but also to the level of pressure. The higher the pressure is. The closer
