초록

The objective of this work was to study the properties of purification of two liquid phase for exclusion of impurities in each phase. The experiments for process variables were carried out in the temperature range($H_{2}SO_{4}$ phase: $413{\sim}513$ K, $HI_{x}$ phase: $353{\sim}453$ K) and in the $N_{2}$ flow rate range($H_{2}SO_{4}$, $HI_{x}$ phase: $50{\sim}200$ mL/min). As the results, it is appeared that the principles of $H_{2}SO_{4}$ phase purification was due to stripping, evaporation and reverse bunsen reaction and $HI_{x}$ phase purification was due to stripping and reverse bunsen reaction. In purification of $H_{2}SO_{4}$ phase, the concentration rate of $H_{2}SO_{4}$ phase was controled by temperature but the temperature had few effects on yield of $H_{2}SO_{4}$. In purification of $HI_{x}$ phase, we observed products of side reactions($H_{2}S$, S) over 433 K. The purity of $HI_{x}$ phase was increased with increasing $N_{2}$ flow rate because impurites were decreased with increasing conversion of reverse reaction.
