This paper summarizes experimental findings of the regenerative capability of nitrogen on Fuller's earth. Regenerating new oil from aged oil involves several cycles requiring a large volume of Fuller's earth. The use of large amounts of Fuller's earth is not economically profitable for companies that carry out regenerative operations to service transformer oils and can have environmental implications, since Fuller's earth is usually used to reclaim transformer oil in a one-time batch basis then disposed of. To improve the situation, a new technique to reduce the number of regeneration cycles is proposed. It is shown that Fuller's earth can be improved by purging it with continuous flowing of a fluid, preferably dry nitrogen.
本文总结了关于富勒土再生能力的实验结果。从老化油中再生新油需要几个循环，这需要大量的富勒土。对于从事变压器油再生操作的公司来说，大量使用富勒土在经济上并不划算，并且可能会产生环境影响，因为富勒土通常以一次性批量方式用于回收变压器油，然后进行处置。为改善这种情况，提出了一种减少再生循环次数的新技术。结果表明，通过用连续流动的流体（最好是干燥氮气）吹扫富勒土，可以对其进行改良。
