Laboratory Testing of a Fluidized Bed Dry Scrubbing Process for Removal of Sulfur Dioxide and Phosphorous Pentoxide from an Inert Carrier Gas.
Abstract
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 studies 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). Keywords: Dry scrubbing; Fluidized bed, Flue gas treatment, Sulfur dioxide, Phosphorus pentoxide.
