Catalyzed water flushing
Thread Content
Do the catalyst columns have full-column flushing for the overhead vapor pipelines? Is it necessary? Thank you!
There is no need for this; flushing the vapor lines requires the towers to be filled with water. In reality, however, the load that the foundations of these towers must bear is not necessarily based on a design with the towers fully filled. Even in designs where the towers are assumed to be fully filled, the calculations are done using the density of the oil. Therefore, doing this is likely to cause the foundations to sink or tilt. Steam purging is sufficient.
In a distillation system, the number of water layers generally does not exceed 16; aside from considerations related to the load-bearing capacity of the foundation, there are also quality-related factors to take into account! But in our case, the water filling and air expulsion processes that take place when the absorption stabilization system is put into operation will exert pressure; therefore, the reverse design should take into account the impact on the load-bearing capacity of the foundation!
