Troubleshooting of Deep Cold Air Separation Equipment

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...

1 pay attention to the direction of the arrow on the valve and the process requirements of the media flow direction, in order to avoid installation errors. 2 The pipeline connected with the valve should be thoroughly cleared of dirt, dust and other foreign mechanical impurities before installation. Prevent damage of the sealing surface of the valve. 3 The cold valve on the cold box should be installed at the same time as the corresponding brack...
