PROCESS AND APPARATUS FOR REGENERATING LOW ENERGY FOR SEPARATION OF ACIDIC GAS

摘要

PURPOSE: Low energy regenerating method and apparatus for separating acidic gas are provided to overcome weather related problems by reducing greenhouse gas. CONSTITUTION: A low energy regenerating method includes the following: carbon dioxide for absorbing and separating carbon dioxide is collected; steam is generated from a boiler based on fuel consumption; condensed steam is heated using a water feeding heater and is supplied to the boiler; and the steam used for collecting the carbon dioxide is transferred to the water feeding side or the heating source side of the water feeding heater according to the condition of water. The water feeding heater is composed of a plurality of low pressure water feeding heaters(30, 31, 32, 33) and a plurality of high pressure water feeding heaters(24, 25, 26).
