What are the different types of reboilers and how do you select between them?

Types include: Kettle reboiler (pool boiling, high heat flux, simple operation, large holdup), Thermosiphon (natural circulation - vertical or horizontal, lower holdup, compact), Forced circulation (pumped flow, handles viscous/fouling fluids), and Fired reboiler (for high-temperature applications). Selection criteria: fouling tendency (forced circulation for fouling), turndown requirements (kettle for wide range), available temperature driving force (thermosiphon needs adequate dT), heat flux (kettle handles higher), and column hydraulics (thermosiphon needs careful elevation design).
