Solvent dehydration, molecular sieve deep dehydration
Thread Content
When high water content levels need to be reduced, using molecular sieves for deep dehydration is a good option; those who are interested can come and discuss this further.
Molecular sieve dehydration is not suitable for solvents containing large amounts of water; it is only appropriate for refining solvents that have been preliminarily dehydrated, enabling the water content to be reduced to levels of several ppm to several dozen ppm. Because after absorbing water, molecular sieves containing a large amount of solvent require complicated and stringent drying and regeneration processes; moreover, the presence of such a large amount of solvent leads to unnecessary waste.
I’m still working on it. Is there anything I can help you with?
Are you a equipment manufacturer? Our company has propylene glycol methyl ether with a water content of 0.5%, and we would like to reduce this water content to 500 ppm through deep dehydration – is such a technique feasible?
Molecular sieves have good adsorption dehydration performance, but desorption and regeneration are rather troublesome. Molecular sieve membranes are more effective at the moment
I am a manufacturer of equipment; it is possible to reduce the water content in propylene glycol methyl ether to 500 ppm by using molecular sieves for dehydration.
We combine molecular sieve adsorption for dehydration with molecular sieve membranes, which reduces costs and also solves the problem of waste solvents resulting from molecular sieve dehydration. QQ 168801110
