Reboiler installation height issue
Thread Content
Dear sea friends, I would like to ask: taking a horizontal thermal siphon reboiler as an example, how can we simply and clearly determine the installation height of such a reboiler? 1. The reboiler is installed too high; the pressure generated by the difference in liquid density between the bottom of the tower and the pipeline leading to the heat exchanger is not sufficient to overcome the liquid level difference and pressure losses, preventing circulation (is this correct?) ） ； 2. The reboiler is installed too low; intuitively, this means that the circulation power increases. But to what extent is it considered unreasonable? And why is it unreasonable?
The input of laypeople is for reference only: lol. The first thing to consider is the liquid level in the reboiler, as this is a characteristic of liquids and therefore deserves priority attention. As for how to determine the height, it should be the required height obtained by comparing the static pressure generated by the liquid level height provided by the main tower as a reboiler with the operating liquid level of the reboiler. As for the gas after evaporation, it is basically not restricted by height. It is best to provide schematic diagrams; discussing them with visual aids makes it easier.
Okay, thank you. I’ll draw a schematic diagram first and then ask again
