ABSTRACT:
An improved process for reducing the sulfur content of a flue gas derived from combination of a sulfur-containing fuel by inserting a dry sulfur sorbent material into the flue gas, then humidifying the sorbent-containing flue gas to enhance sulfur removal. The humidified flue gas is then subjected to electrostatic precipitation separation of solids, the first separated portion containing the highest unreacted sorbent values, which values are reinjected into the flue gas.
