The reflux liquid in the upper column of the distillation column is throttled by the lower column to the liquid air and liquid nitrogen of the upper c...
When the same pressure is reduced, the temperature drop of throttling is far greater than that of expansion. This is because the gas does not work ext...
1. It is easy to produce air hole when the flux is wet 2. If the welding speed is too fast, it is easy to produce welding porosity 3. Welding gas ho...
With the development trend of large-scale air separation plant, the column support of its matching cold box equipment tends to be large-scale. The tra...
The upsizing of air separation plant has became an inevitable trend of the development of national economy. A few years ago, the domestic air separati...
In order to check the installation quality, deformation under low temperature and smooth condition of pipelines, valves and field installed air separa...
After a long-term operation of the air separation plant, the components in the cryogenic equipment and pipelines in the distillation system will be bl...
In general, the liquefaction temperature of nitrogen is higher than that of oxygen, but why can the condensation evaporator between the upper and lowe...
1. Enter the work area, wear all kinds of labor protection equipment; check the surrounding working environment; confirm the tools and machines; prohi...
The environmental conditions considered by the air separation plant include: altitude, atmospheric pressure, ambient temperature, air humidity, the co...
Air separation plant is an important supporting facility for large-scale industrial enterprises, such as chemical industry, smelting industry, electro...
After a long-term operation of the air separation plant, the components in the low-temperature equipment and pipelines of the distillation system will...
