Size of the air separation unit

Size of the air separation unit
Generally, the size of the air separation unit is measured by oxygen production, and the unit is Nm3 / h, which means how many cubic meters are produced per hour. The size of the air separation plant needs to be selected according to the actual production needs of the enterprise, not the larger the better.

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. ...

The main causes are as follows: 1. The structure is unreasonable, the welding seam is concentrated and the welding joint stress is too large. 2. When welding, the molten pool is too large and overheated, and the alloy is burnt too much. 3. The arc crater is not filled due to too fast arc closing and too early wire drawing. 4. Material problems, for example, when Mg content is less than 3%, and impurities such as Fe and s exceed the standard, it is easy to cause cracks. When the melting temperature of welding wire is too high, liquefaction cracks in heat affected zone are easy to occur. Preventive measures include: 1. During the design, attention should be paid to the reasonable arrangement of welding seams, avoiding the stress concentration as far as possible, and selecting the welding sequence reasonably. 2. Reduce welding current or increase welding speed properly. 3. The arc stopping operation technology should be correct, and the arc pit should be filled by adding the ou
