Recovery cycles of distilation system
Recuperative cycles of distillation apparatus -BRU, during production alcohol.
Let us consider an example of the consumption of energy resources (live steam) mash and
rectification columns at the plant 3000 dal.
The scheme of work is shown in fig. No. 1
The total consumption of energy resources by the two columns is:
heat energy in the form of live steam 42 kg /dal; cold in the form of reverse
water 42 kW /dal.
Consumption of hot steam by columns (Distillation system - 3000)
Total steam consumption for a six-column BRU-3000 dal
* steam consumption depends on the strength of the brew and the operating mode operation column
| Mash column | Epuration column | Product-concentrating column | The final purification column | Rectification column | Spin column |
| up to 19 kg /dal | up to 8 kg /dal | up to 23 kg /dal | up to 8 kg /dal | up to 4 kg /dal | up to 4 kg /dal |
Operation using a regenerative circuit (using a secondary heat) allows you to save heat energy in the form of live steam for heating mash column and part of the energy for cooling the rectification column.
Consumption of hot steam on columns (Distillation system 3000-BTS Engineering)
Total steam consumption for a six-column BRU-3000 dal
* steam consumption depends on the strength of the brew and the operating mode operation column
| Mash column | Epuration column | Product-concentrating column | Final Purification Column | Rectification column | Spin column |
| - | - | up to 4 kg /dal | up to 8 kg /dal | up to 23 kg /dal | - |
The total consumption of energy resources by two columns in the recuperative the diagram is:
- heat energy in the form of live steam 26 kg /dal;
- cold in the form of recycled water 26 kW /dal.
That is, the savings only on the use of recuperation on a bundle Distillation column - Mash column is:
- heat energy in the form of live steam 20 kg /dal;
- cold in the form of recycled water 16 kW /dal.
