Regarding the problem with the pipeline behind the injector in Topso
Thread Content
Everyone: Recently, while carrying out on-site inspections of the pipelines together with Topso’s design engineers, it was found that the shortest distance required between the ejector outlet and the main deck junction point has already been taken into account in the design; however, it is still not possible to achieve a shorter distance on site – there is still about 5 meters between them. As these pipelines will be in a cold state at the beginning of operation, water may accumulate in this area. How do you guys in the factory avoid this problem? In terms of operation? Were other measures added as well?
If condensate is generated at the outlet, the pipeline should be designed with a certain slope in the direction of drainage to prevent the accumulation of condensate at the outlet. The outlet pipeline must not have an upward slope; otherwise, vibrations and noise may occur, which can damage the injector!
Upstairs, I might not have expressed myself clearly. What I want to ask is regarding this specific manufacturing process: due to the requirements of the catalyst, there are strict constraints on the inlet temperature. I would like to know about the length of the pipeline at the outlet of the injector, as well as how insulation and heating can be implemented to prevent the formation of condensation water.
Then calculate the insulation thickness based on the pressure gauge, condensation temperature, outlet temperature, and pipe length!
““Pressure gauge” == outlet pressure!
Well, calculating the appropriate insulation thickness is also something to keep in mind, but it still doesn’t solve the problem of cold pipes when they are first put into use.
If under pressure vacuum, install a drain and condensate valve at the lowest point； If the pressure is high, add a steam trap.
For heat tracing, we use medium-pressure steam as required by the design.
Thank you, 9#. Is the medium-pressure steam generated by the drum? The process supplier recommends electric heat tracing.
