I would like to know how the industrial dehydration of propylene to produce high-quality propylene is carried out What are the operating pressure and reflux ratio? According to A+ forecasts and industry experts, this system has dead zones in the high-concentration area at atmospheric pressure; it is difficult to obtain high-quality products using conventional distillation. Operation under slightly negative pressure is required, or the distillate with excessive water content must be passed through a dehydrating agent for dehydration. I wonder what insights other sea friends have?
I’m not quite sure; let those who are more knowledgeable give me some advice! ! !
What are you for? Is it a graduation project or industrial production?
Of course it’s industrial production, not a graduation project. To truly obtain it……
Thank you! Are large-scale industrial projects suitable for this method?
I think we can try a small experiment using thin-film evaporation
Now, thin-film evaporation systems are gradually replacing some outdated distillation systems
Ordinary distillation has such problems. Molecular sieve adsorption, such as in ethanol dehydration, can be carried out on a large scale; I’m not sure about the situation with propylene dehydration. Membrane separation should work, but on a relatively small scale. Also looking forward to expert answers.
