Flow direction in the shell side of the bottom reboiler of the diesel gas stripping tower.
Thread Content
Here, the diesel in the shell side has a low inlet and high outlet, while the paraffin oil in the tube side also has a low inlet and high outlet. Suddenly, someone suggested modifying it to a pipe with high input and low output. I don’t think this is reasonable. The process for dual-low feed can fully meet the process specifications. What is the flow path of the medium in the reboiler in your facility?
That is, who can share the applications of parallel-flow heat exchangers and the practical benefits brought by this design?
The principle for the inlet and outlet of the heat source in a heat exchanger is high inlet and low outlet.
