The feed flow rate is 25 tons. The feed pipeline has a diameter of DN80. What size holes need to be made in the DN80 pipelines, which are 2 meters long each, and how many such holes are required to meet this feed flow rate? How to calculate it?
This expression is frustrating. Could you make it clearer?
As far as I know, the maximum flow rate for a 80-series pipeline is around 100 tons – you don’t need to make any openings; just feed it in directly. P
To modify the feed location of a distillation column, this is done through an access hatch; a section of pipe is inserted into this hatch to serve as a liquid distributor. Making holes in this inserted pipe would allow for even distribution, but it could have a significant impact on the operation of the column. Therefore, it is necessary to calculate the diameter and number of holes to be made in the inserted pipe section – what formula can be used for this calculation?
It affects the distribution and tower operation; is there a formula for calculating this? When designing the tower, the number of holes in the feed distributor is definitely determined through calculation
This is a distributor design issue; simply put, the total area of all the holes should be greater than the cross-sectional area of the 80 pipes. The flow rate needs to be controlled by valves on the pipeline, not by openings
Hehe, I also think the question he should actually ask is how to allocate things more effectively after improving the feed inlet, in order to minimize the impact on tower operation! The maximum amount of material that can pass is determined by the size of the pipeline; under normal conditions, the flow rate is controlled through control valves, rather than by the degree of openness of the pipeline.
