Biogas purification cases

We calculate the number of plates assuming that the liquid and vapour on each plate are interacting to reach equilibrium. In practice, it is not possible to achieve an ideal equilibrium for all plates in a nitrogen distillation column, so the actual number of plates required is greater than the theoretical number of plates required. The ratio of the theoretical to the actual number of plates is the full tower efficiency. Factors affecting the full tower efficiency are: the gas phase and liquid p...

The impeller is the component of the centrifugal compressor that does the work on the gas, in which the temperature pressure and flow rate of the gas are increased. The impeller is a key component in determining the performance of the centrifuge. The impeller must be designed and manufactured to meet the following requirements: it must transmit more energy to the gas flowing through it; the gas flow in the impeller must have low energy losses; and the impeller's structural, thermal and flow par...
