What other processes are available for the dehydration of ethylene glycol besides distillation?
Thread Content
As the title suggests, ethylene glycol is commonly used as an extractant, and distillation is the most common method for its regeneration, although it requires high energy consumption. Are there any other processes running? Only one method of osmotic evaporation was found; I’m not sure if it will work http://cdmd.cnki.com.cn/Article/CDMD-10056-2008184977.htm
Dehydration vacuum distillation of ethylene glycol is okay.
Where can we go with distillation dehydration? The issue is just the high energy consumption. Do you work with molecular sieves?
Yes, it’s vacuum distillation; it depends on the water content – the higher the water content, the greater the energy consumption.
