AN APPARATUS BY USING HIGH-TEMPERATURE ALKALINE MOLTEN SALT FOR THE TREATMENT OF OFF-GAS CONTAINING HIGHLY CONCENTRATED CHLORINE GAS AND METHOD THEREOF

摘要

PURPOSE: An apparatus and a method for processing exhaust gas containing high concentration hydrochloric acid gas using high temperature alkaline molten salt are provided to minimize the generation of wastes by converting the wastes into a recyclable form. CONSTITUTION: Exhaust gas contains high concentration hydrochloric acid gas which is generated from a pyroprocess for recycling wasted nucleus fuel. A reactor(6) is filled with a liquid alkaline molten salt. The exhaust gas is dispersed into a vapor shape in the liquid alkaline molten salt and is reacted. The exhaust gas is cooled after the reaction with respect to the liquid alkaline molten salt. The cooled exhaust gas is filtered using a filter(9). The liquid alkaline molten salt is liquid Li_2CO_3 molten carbonate.
