Problems with methanol distillation
Thread Content
What measures can be taken during methanol distillation to increase the yield of high-quality purified methanol? Please feel free to speak up. Thank you
Improving product quality means making full use of the functions of each column: extending the extraction time in the pre-column and using sufficient amount of extraction water to effectively remove light components as well as organic substances with a boiling point similar to that of methanol. It is also important to operate the main column properly, controlling the temperature of the reflux liquid as well as the temperature and pressure differences within the columns. To ensure the highest possible quality of the product, it is advisable to increase the reflux rate appropriately. In essence, the key is to continue removing fusel oils while maintaining the proper operating parameters of the columns, along with an appropriate increase in the reflux rate. Simply put, to improve product quality, it is necessary to operate each column correctly and keep removing fusel oils.~~~~~
If you follow what’s said on the 2nd floor, energy consumption will increase significantly. Companies will refuse if the energy consumption is too high.
Distillation mainly involves the control of operational parameters such as temperature and pressure; steam is of key importance, along with the reflux ratio. If these are well controlled, there should be no major problems
Just control the condensation temperature of the pre-tower, as well as the temperature, pressure, and reflux of the main tower
Just keep a few balances in check!
If the product is already of acceptable quality, the best way to further improve it is to control the liquid level at the bottom of the main distillation tower; by slightly reducing the temperature inside the tower and increasing the reflux rate, the product quality can be improved. However, excessive backflow will increase the proportion of light components inside the tower, and the quality of the wastewater must also be taken into account. This is my personal opinion; I welcome everyone’s feedback. Please also suggest some good solutions.
What all the gentlemen mentioned above are are theoretical approaches; are there any specific procedures or parameters that can be used as a reference, or any well-established technical indicators? Thank you.
Control the reflux ratio, tower temperature, and pressure
Control parameters such as the reflux ratio, temperature, and pressure properly
I think controlling the quality of precision armor is not just a matter of distillation; a large part of it also lies in synthesis. The poor quality of the crude armor produced also has a significant impact on the quality of the refined armor.
