Discussion on reflow ratio
Thread Content
In the methanol gas phase dehydration to dimethyl ether unit, the reflux ratio (ratio of reflux flow and product discharge volume) of the dimethyl ether distillation tower (the main material system is dimethyl ether, methanol and water) is taken as 0.8 in the simulation calculation to achieve more than 99% of the dimethyl ether product. Is this reflux ratio sufficient in the actual unit? The reflux ratio of the methanol recovery tower (the main material system is methanol and water) is taken as 0.65 in simulation calculation to ensure that the alcohol content in the discharged wastewater is below 0.2%. Is the reflux ratio in the actual device sufficient? Please give me some advice.
Sometimes the calculation using craftsmanship is not accurate, and the calculation is different every time.
Each set of equipment is different, and the actual debugging shall prevail. . . . .
No matter how you simulate it, it is still something on paper. The most appropriate reflux ratio needs to be proven by actual operating data. The process is the same, the equipment is different, and the reflow ratio will be different. When the process is stable, the reflux ratio is generally not adjusted.
