Equipment for solvent recovery
Thread Content
I would like to ask about the recovery of an ethyl acetate-butane mixed solvent (with about 80% ethyl acetate). I found online that extractive distillation columns can be used to recover ethyl acetate at a purity of over 99%, but there is little information available online regarding such columns. If a purity of over 90% is sufficient, then would ordinary distillation work in this case? Are there any manufacturers that produce equipment for extractive refining of hexa? !
You can use it in combination with a spiral-wound tubular condenser to recover up to 95%. 15023676337
Is the extractive distillation column also used in conjunction with a vacuum system? All the solvent recovery projects we have done before were like this.
