Bradshaw, W M

A series of tests was conducted to evaluate a dry-scrubbing process in which acidic gases are removed from an inert carrier gas stream by contact with lime in a fluidized bed operating in the bubbling-bed regime. The acidic gases studied were sulfur dioxide and phosphorus pentoxide. The process parameters studied include temperature, gas flow rate, humidity, and acidic gas inlet concentration. At the conditions tested, the removal efficiency typically exceeded 99%. However, lime utilization > 9% was not tested. Test data indicate that sulfur dioxide and phosphorus pentoxide readily react with calcium oxide in a bubbling bed operating between 480 and 650 C (900 and 1200 F).
