Technology Introduction
Crude methanol rectification process includes single-column process, two-column process, three -column process and energy-saving three-column process. The feature of Four processes are as follows:
No. | Crude methanol rectification process | Feature |
1 | single-column process | 1.Methonal-water regroup, separate in one column |
2 | two-column process | 1.The combination of pre-recification column and main rectification column |
3 | three -column process | 1.Three rectification column work under the same pressure. The third rectification column produces |
4 | energy-saving three-column process | 1.Two main rectification columns and final rectification column, the first main rectification column is pressure-increasing column. The second one is normal pressure column. Two columes produce 50%-50% |
Our company's crude methanol distillation technology is based on the fourth energy-saving three-tower process, the main feature is to fully optimize the heat transfer network, so that the use of steam and circulating water to a minimum, in order to achieve energy conservation and investment optimization.
(1) High yield of the process: fine methanol recovery rate of 99.86% (refined methanol production and feed the amount of methanol contained in the ratio)
(2) Using a mature double-effect distillation method: the use of pressurized overhead gas phase for the atmospheric tower reboiler heat source.
To 300,000 tons / year 90.82% methanol distillation as an example.
