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%.
