摘要

Abstract

In this paper a technology of parametric pumping fractional crystallization and a crystallizer with a slug flow vertical bubble tube are presented. This technology and crystallizer are applied to the refining of naphthalene. The purity naphthalene obtained is over 99％ and collection efficiency is over 92.5％．
