The following article on oil reclamation and recovery was taken from sources by HOPU
Regeneration is the term used for renewing used transformer oil back to virgin oil specifications. Degassification refers to the minimisation of gasses present within the oil, dehydration refers to the minimisation of water content and filtration to the removal of particulate matter.
Percolating the used oil through several columns of an adsorbent media performs regeneration. The media removes all impurities, reduces the neutralisation number and power factor, increases the interfacial tension, restores oxidation stability and performs a colour correction in addition to acting as a fine filter and dehydrator. To all extents, the processed oil is indistinguishable from new.
HOPU has been used as the adsorbent media. The disadvantage of using this type of media is that once it is saturated, it needs to be discarded. The media blend used by Enervac is a mixture of oxides of titanium, silicon, aluminium and iron and can be reactivated in situ more than 300 times, under normal operating conditions. This typically means that it has to be replaced every four or five years. At the end of its useful lifetime, the media can simply be discarded in a normal landfill site, as it will contain no oil. Reactivation is automatically achieved by inter alia thermal regeneration.
