Description

The course project "Continuous distillation column with sieve plates for separating the mixture of acetone - ethyl alcohol" was carried out on the basis of practice data.

The project is based on the technological process of separation of a mixture consisting of acetone and ethyl alcohol in a distillation column using sieve plates.

Material and heat balances were made, the main dimensions of the column were determined: its height and diameter, the number of plates; The hydraulic resistance of the apparatus is calculated. A drawing of the column was made in two projections with the development of a node - a sieve plate TS-R.

Source data:

1. The capacity of the plant for the initial mixture Gf is 6000 kg / h.

2. The content of the low-boiling component:

in the initial mixture - = 40% (moln.),

in distillate - = 96%,

in the bottom balance –= 2%.

3. Pressure in the column - P total = 760 mm Hg.

4. The mixture is fed into the column at the boiling point.

Defined:

1. Material and heat balance.

2. The diameter of the absorber is Dк, m.

3. The height of the column is NK , m.

4. Hydraulic resistance – ∆r, kPa.
