Info

Disadvantages of Operating Pervap at Highest Possible Temperature • Harmful to temperature-sensitive compounds and microorganisms • Higher likelihood of precipitate formation and blocking of flow spacer • Requires additional heaters and heat exchangers
The benefits of high temperature operation typically outweigh the costs Temperature sensitive organisms and compounds must be removed prior to pervap system Filtration or centrifugation required (microfiltration units are less expensive than pervap units) Enables use of any type of pervap module
