Analysis of the reasons for high pressure drop in some condensers

Currently, the preliminary assessment is that the interval between the lower baffle plates is too small, which results in poor fluid flow. The liquid phase has to continuously flow over the lower baffle plates, leading to severe gas obstruction and a high pressure drop in the condenser. Does anyone else have insights on this?

This depends on the original usage parameters; it is possible to analyze whether they match the original design parameters. Typically, the performance parameters of coolers are measured by the temperature difference to determine the cooling efficiency. Under normal use, the flow resistance generally does not become less than the resistance of the pipe cross-section. Unless there is a blockage caused by subsequent use. For reference.

Simply based on the layout of the baffle plates in the drawings, the poster’s analysis makes sense; it would be good to verify it with software. The original intention of this process designer was for the gases on both sides to overcome condensation due to the adjacent dense baffles and be discharged from the outlet; heat transfer efficiency was to be achieved at the cost of higher energy consumption. It is unknown what the vaporization rate at the outlet of the actual equipment is, and what the difference is between this value and the theoretical outlet temperature recovery rate Personally, I think that doing this will not result in a high vaporization rate.

The baffle design is unreasonable! There is a problem with the layout of the gas inlet and outlet!

The designed liquid-phase feeding temperature should be 62°C; this is the difference, and it’s likely this reason that results in a relatively large pressure difference

The software did a check, and according to the designed liquid discharge temperature, it’s roughly 18 KPa

Is the gap of the baffle insufficient? Specifically, I heard that holes usually need to be made in the lower baffle to ensure fluid flow – is that true?

There are still some doubts regarding your question. Should attention be paid to whether the requirements are met, that is, whether the cooler functions as intended? If it is not a design-related issue but rather a problem that arises during use, one should first check whether the problem observed during use is accurate. It seems to be a control problem. For example, it is important to know whether the cooling liquid is fully filled in the cooler when in use, as only then can the maximum heat exchange efficiency be achieved. ，，，，，。 It is recommended to provide more details on the issues on site; it would be best to include a simple diagram of the relevant process flow. Nor should one pose questions in a biased manner by incorporating things that cannot be understood based on one’s own subjective wishes. To reflect the actual conditions on site, facilitating discussion and providing a reference.

My knowledge is limited; I can’t understand it. It only mentions a large pressure difference, and is it appropriate to analyze things from just the perspective of the equipment itself?
