Stirring tower of diesel hydrogenation unit
Thread Content
The stripping tower of the diesel hydrogenation unit is currently operating at a pressure of 0.65 Mpa (with a design pressure of 0.8 Mpa). The flow rate of medium-pressure steam used for stripping is 2 t/h; it is possible to reduce steam consumption by lowering the tower pressure and thus the amount of steam injected. Is it feasible
While ensuring the quality of the product, it is possible to try reducing the tower pressure in order to decrease the amount of air blown in~~
According to Dall’s law, appropriate adjustments should be made
0.45 is a more cost-effective option; also, pay attention to the dry gas volume
Reducing the tower pressure causes the lighter components to rise, which may result in the product not meeting quality standards. Therefore, while striving to reduce energy consumption, it is important not to compromise product quality.
Depends on the pressure required for the non-condensable gases in the stripping tower
It is possible, but the adjustment of the ratios needs to be based on the amount of dry gas at the top of the tower. It is recommended to maintain a certain amount of steam in order to ensure effective stripping within the tower. Given the limitations in terms of energy-saving steam usage, it might be advisable to use the ASPEN software for simulation.
