Please note that there are two types of thermosyphon reboiler. You have studied a vertical ther Advantages of the horizontal type compared with the vertical include: the length of the tubes is not connected with the hydraulic balance. This allows the designer m The length of the shell does not affect the height of the attached column or the elevation of the two feed lines and vapour return lines can be used liuid heating medium such as hot oil is better suited to the tube side, giving a better film coeffi turndown is better because the height of the vapour and liuid legs are !roughly" independent # agree with you that the vapourisation ratio should be about $%& on a 'A(( )*+ basis. # b
