Proprietary Technology and Plants

TechnologyIntrodction:

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:

	Crude methanol rectification process	Feature
1	single-column process	2.Advatange: investment saving, reduce heat energy consumption 3.Disadvantage: the purity of refined methonal is not very pure.
2	two-column process	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	2.Advantage: high purity 3.Disadvantage: high investment. Need more area
4	energy-saving three-column process	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.

(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.
