Method for making sulfur dioxide-containing gas stream |
摘要 |
Improvement in the method for making a sulfur dioxide-containing gas stream of low elemental sulfur content by contacting a stream of oxygen-containing gas with elemental sulfur maintained above its auto-ignition temperature to generate a gas stream containing sulfur dioxide and gaseous elemental sulfur, followed by contacting this gas stream with liquid elemental sulfur maintained below its auto-ignition temperature, which improvement involves subsequently scrubbing the gas stream in a confined area with water or an aqueous medium, preferably containing small amounts of ammonia, under conditions of turbulent flow to obtain a sulfur dioxide-containing gas stream substantially free of oxygen and sulfur trioxide and containing less than about 0.0002 lb. of sulfur per cubic foot of gas, measured at standard conditions.
