Abstract
Sulfur dioxide is removed from a gas stream, such as that generated by the combustion of a sulfur-containing fuel or ore processing, by introducing particulate nahcolite into the gas stream in a high temperature zone. The high temperature zone provides an environment for the size reduction of the particulate nahcolite and an effective environment for the removal of the sulfur dioxide. The size reduction of particulate nahcolite is accomplished by a thermal crushing process.
