SYSTEM FOR SEPARRATING ACID GAS IN THE POWER PLANT EQUIPMENT

摘要

PURPOSE: An acid gas separation system for a power plant facility is provided to reduce the thermal consumption of a desorption tower by heating an absorption agent with the residual heat of exhaust gas. CONSTITUTION: An acid gas separation system for a power plant facility uses a denitrification facility(20), a heater(30), an electric dust collector(40), and a flue-gas desulfurization facility(50) to process harmful gas discharged from a boiler(10). The gas processed by the flue-gas desulfurization facility passes through a first heat exchanger in between an absorption tower absorbing oxygen gas and a desorption tower regenerating the oxygen gas before being discharged to the outside.
