Crude Methanol Refinery Technology - China

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 - Advatange: investment saving, reduce heat energy consumption 3 - Disadvantage: the purity of refined methonal is not very pure.

2 two-column process 1 - The combination of pre-recification column and main rectification column 2 - Refine crude methonol including dimethyl ether and other light components and reducing impurities 3 - Advantage: simple process, user friendly, less investment 4 - Disadvange: high energy consumption, low purity

3 three -column process 1 - Three rectification column work under the same pressure.

The third rectification column produces 2 - Advantage: high purity 3 - Disadvantage: high investment.

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% 2 - Advantage: envery saving, reduce the ethanol content of the purified methanol, product quality is better; methanol yield is higher, low operating costs 3 - Disadvantage: high one-time investment

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.
