摘要

PROBLEM TO BE SOLVED: To provide a gas purification system that can remove a suspended solid (SS) component in treated water from wastewater disposal facilities and remove a tar component from gases from wastewater disposal facilities. SOLUTION: The gas purification system comprises: a low-temperature dust collecting apparatus 20 for removing dust from a gasified gas generated from gasification facilities; gas-washing facilities A for washing the gasified gas cleared of dust by the low-temperature dust collecting apparatus 20; and wastewater disposal facilities for disposing of washing wastewater discharged from the gas-washing facilities A. The system is provided with a condenser 101 for separating a liquid component from an ammonia-containing gas discharged from the wastewater disposal facilities and a separator 102 for separating the tar component Tr from the liquid component discharged from the condenser 101.
