A distillation column may have to be raised off the ground in order to accommodate the reboiler. This may cause a mechanical design problem with the column. Stability of the column may become an issue. 2 Horizontal Thermosyphon Reboiler This is perhaps the most common type of reboiler.

3 Since the number of specified variables (8) is equal to that of the degrees of freedom (8), the problem can be solved, which means that we can draw all operating lines and the feed line(s) step off stages - to find the number of equilibrium stages required for that problem For a ternary (3-component) mixture, the degree of freedom is 3 + 6 = 9 Thus, we need to have 9 specified variables to

The old adage - prevention is better than cure - applies to the design of all process equipment. The majority of distillation column designs meet their 

More often problems in distillation columns are associated with changed circumstances - changed operating conditions or changed product specifications - or in the extreme a changed duty to effect a different separation. Whatever gave rise to the problem the distillation column is not achieving the required separation and/or capacity.

2. We wish to use a distillation system of a still pot plus a column with one equilibrium stage to separate a mixture of methanol and water. A total condenser is used. The feed is 1 kmol with 57 mol% methanol. The desired a final bottom product concentration is 15 mol% methanol. The system's pressure is 101.3 kPa. The reflux is a saturated

one obtains the near about solution for the design problem. This solution can be used to minimize the rating runs required to arrive at the solution of design problem. This, perhaps, is widely design method at present. The design method has been revived recently in the context of azeotropic distillation and to determine rigorously the minimum

Thermische Verfahrenstechnik I binary distillation Binary distillation Using a tray column, a binary mixture with components A and B has to be separated by distillation. The feed F with x F,A is a two phases stream with 50% vapor. It is separated into three parts: - a distillate stream D with y D,A (vapor) - a bottom stream B with x B,A
