Abstract:
Roasting sulfide ore to produce high-strength SO2 using steam as the fluidizing agent and commercial grade O2 as the oxidizing agent to produce a mixture of SO2 and steam and condensing the steam to produce high-strength SO2 with reduced or negligible dilution by atmospheric gases.
Abstract:
A feed distribution system for feeding slurry to a fluidized bed reactor through a plurality of feed guns placed around the periphery of the reactor. The feed distribution system includes a feed distribution tank and having no mechanically moving parts located above the reactor. The tank is divided by baffles into essentially two concentric zones, namely an inner zone which serves as a feed reservoir and an outer zone which is further subdivided into individual compartments and serves to feed slurry at a steady rate to said feed guns. Also disclosed is a process utilizing said feed distribution system.
