Abstract
A system and method for desulfurization or acidic gas removal from a hot flue gas is provided that uses a dry sorbent injection technology with downstream sorbent reproduction based on a dual-alkali process. As such, lime and flue gas carbon dioxide are used in a process to produce the dry sorbent, sodium bicarbonate.
