<br /> While sulfolane is highly stable and can therefore be reused many times, it does eventually break down
<br /> into acidic byproducts. A number of measures have been developed to remove these byproducts,
<br /> allowing the sulfolane to be reused and increase the lifetime of a given supply. Some methods that have
<br /> been developed to regenerate spent sulfolane include vacuum and steam distillation, back extraction,
<br /> adsorption, and anion-cation exchange resin columns.
