Abstract:

This paper presented further processing for naphthalene oil in China and abroad,summarized rectification method,crystallization method,hydrogenation method and separation technologies,such as liquid membrane separation,supercritical fluid extraction,etc.to be used for naphthalene oil separation.It also proposed a combination of conventional process and the advanced separation technology based on the related analogues formed by the naphthalene and other components in the naphthalene oil in the hope of improving naphthalene oil separation and process conditions with preconditions of optimized process,simplified production and energy-saving & pollution reduction.
