Issues regarding the thermal siphon type bottom reboiler
Thread Content
Could someone please explain the working principle of the thermal siphon type bottom reboiler? Is flow generated due to the difference in fluid density? And that’s when the siphoning phenomenon occurred? Are there any other causal relationships?
It is described in great detail in various chemical engineering design manuals; the original poster might want to take a look
It is primarily the driving force generated by the density difference between the vapor and liquid phases that enables the thermosiphonic circulation. If the density difference between the two phases in the reboiler is not significant, options such as pump-driven circulation may need to be considered.
The siphon method requires a high level of cleanliness and low viscosity for the rings. Additionally, care should be taken to ensure that the flow rate of gas and liquid at the outlet is not too low; it’s not true that the larger the pipeline design, the better
