FAQ

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 externally during throttling, but when the molecular spacing increases, the potential energy of molecules increases, and the kinetic energy decreases correspondingly, reflecting the decrease of temperature. The expansion refrigeration not only increases the potential energy between molecules, but also makes external work to push the impeller to rotate or push the piston to move. All these energies need to reduce the kinetic energy of molecules, so the molecular kinetic energy decreases more and the temperature drop is larger.

Regeneration of adsorbent in air separation equipment and regeneration method

The structure of the water cooling tower selected for air separation equipment has the following broad types. Sieve plate tower. Tower plate using aperture and hole spacing of the larger shower drop tower plate. Nitrogen and water are from the sieve hole through. As the water cooling tower is not working continuously and steadily, the cooling effect is not ideal, so it is no longer used. Cyclone plat...

In the air separation plant, the adsorption capacity of the adsorbents is expressed by static adsorption capacity and dynamic adsorption capacity. The static adsorption capacity is the largest amount of adsorbed substance when the adsorbents per unit mass (or unit volume) reach the adsorption equilibrium under certain temperature and certain concentration of absorbed components, that is the ratio of the maximum adsorptive capacity (equilibrium value) that can be reached by the adsorbents to the adsorbents. The dynamic adsorption capacity is the adsorptive capacity when the absorbents reach the "conversion point" (expressed by the average adsorptive capacity per unit of absorbents in the adsorber ). Generally, it is calculated by "conversion time", that is, the time from the fluid contacting the absorbents layer to the "conversion point. "Turning effect point" is the point where the concentration of absorbed component increases obviously when fluid flows out of the absorption layer. ...

What aspects should be noted during the operation of the molecular sieve purification system in air separation equipment?

Oxygen generators are switchable heat exchanger process oxygen generators and molecular sieve pressurised expansion process oxygen generators. The pure liquid nitrogen supplied to the upper tower is less and a stream of dirty liquid nitrogen can be pumped to the upper tower.   The oxygen generator of the pressurised expansion process, b...

1.Before filling alumina and molecular sieve adsorbent into the adsorber, personnel should be arranged to enter the adsorber to check whether the screen screen is damaged. If there is any damage, it must be repaired before filling. 2.The quantity of adsorbent should be counted during loading and unloading, and the packing barrel and bag of adsorbent should be prevented from being damaged, and the adsorbent should be prevented from getting damp due to poor sealing. 3.The molecular sieve in the container should be filled in dry weather without rain. Personnel entering the container shall wear oil-free work clothes and caps and clean soft soled shoes.
