Dehydration of ethylene glycol aqueous solution
Thread Content
Our company has a batch (approximately 200 T) of ethylene glycol solution with a water content of over 50%. Does anyone here have experience with or knowledge of methods for dehydrating ethylene glycol? It would be ideal if there are factories that possess mature technology and equipment for this purpose.
Want to sell it at a low price to companies with the capability to handle it
What are the components? Is the water purified water or raw water? If it is purified water, it could be considered for sale to manufacturers that use refrigeration units as a coolant; 20% or 40% ethylene glycol water solutions are common coolants
Separation can be achieved through fractionation, while purification and separation are carried out via distillation and cooling; these techniques are relatively mature but require a significant amount of energy.
Sell it directly to companies that produce antifreeze
200 tons – it’s a waste to use them in equipment; unless a stable supply can be secured, they should be sold to those who deal in resource recycling
