Isoprene separation

Thread Content

What are suitable methods for separating isoprene from fermentation broth?
Reply #22016-02-15
0.4% of isoprene is present in the air; is there any way to concentrate it? I hope experts can help

Consider the condensation method – use saltwater for condensation!

I agree with what was said above; condensation should be used for this purpose. If recycling is taken into consideration, the condensed isoprene should be promptly treated with an appropriate polymerization inhibitor, as isoprene tends to polymerize easily :)

Thank you to both experts! I have another question: I remove isoprene from the fermentation broth through the air. Although condensation can help to precipitate some of the isoprene, the air containing cold hydrazine (which contains isoprene) will then carry the liquid isoprene back out. There is a large amount of air, and if isoprene is to be recovered, the size of the subsequent extraction equipment must be increased.

Is the poster the manufacturer? Please clarify the process conditions, and I’ll do the calculations for you. Based on what you’ve said, it seems that the main issues are related to condensation parameters and equipment selection. If you’re willing to invest a little extra money, we can set up this recovery process for you~:lol

Everyone who takes on jobs has shown up, haha, not bad at all

Can it be compressed before being fed into the subsequent processing equipment?
Reply #92016-02-16
:) It should have little to do with compression; after compression, the temperature rises and then it condenses~~ I personally don’t think it’s necessary :)

Haha~~ It’s still all because of the economic slowdown
Reply #112016-02-16
The key issue is that condensation cannot solve the current problem; isoprene cannot be recovered. Are there any other methods?
