This method may also be used for the thermal design of borizontal tbermosipbon reboilers. The recirculation rate and pressure profile of the thermosiphon loop can be calculated by the methods of Fair [Pet. Rt ner, 39(2), 105-123 (I960)].

Make a preliminary mechanical design for the vertical thermosyphon reboiler for which the thermal design was done as Example 12.9 in Chapter 12. The inlet liquid nozzle and the steam connections will be 50 mm inside diameter. Flat plate end closures will be used on both headers. The reboiler will be hung from four bracket supports, positioned 0.5 m down from the top tube plate. The shell and tubes will be of semi-killed carbon steel. 

Check if this reboiler would be suitable for the duty specified. Only check the thermal design. You may take it that the shell will handle the vapor rate. Take the physical properties of the process fluid as liquid density 535 kg/ m, specific heat 2.6 kJkg °C, thermal conductivity 0.094 Wm °C, ...
