I would like to ask what products come out of the top and bottom of the distillation tower after the crude methanol is distilled
Thread Content
As the title suggests, thank you. Also, I would like to ask if there is only one column for the crude methanol distillation tower?
I’m not from the methanol industry. I think what comes out of the tower top is methanol. What comes out at the bottom of the tower are by-product organic substances or impurities with a boiling point higher than that of methanol.
The common distillation processes for methanol include three-column and four-column processes; more detailed information on these processes can be found by searching this forum or other websites； What are the materials at the top and bottom of a methanol distillation tower? This question is a bit too general, but generally speaking, the material at the top of the tower is refined methanol ； At the bottom of the tower is another methanol-containing mixture containing reformed components, or water. Overall, this question is too broad and not specific enough; these are the only things I can think of.
Methanol production? Generally, there is no such thing as a \"crude methanol distillation column.\" The products at the top and bottom of the column depend on the type of column; in some cases, it is methanol at the top, while in other cases it is methanol at the bottom
Generally, in the three-column process, the light components come out of the first column; pure methanol is obtained from the top of the second column, while water containing a small amount of methanol comes out of its bottom. This mixture then enters the third column, where pure methanol is distilled from the top, and the water at the bottom is sent for wastewater treatment and reuse! Generally, the industry requires a high purity of methanol; often, the methanol from the tops of the second and third columns is mixed together to meet the product specifications, and this is achieved by controlling the flow rate and methanol content at the bottom of the second column Those familiar with the PRO/II methanol distillation simulation should be well aware of this.
