Abstract
A combined spray dryer and gas filter vessel in which a solution containing sulphuric acid and solids, and a hot drying gas, are introduced vertically through the top of the vessel into a spray zone. Solids are removed at a single point at the bottom of the vessel. Filters located above the spray zone clean gas leaving the vessel, and the cleaned gas exits at the top of the vessel. The compact design reduces insulation requirements while avoiding condensation which would create corrosion and yet it provides good separation of solids from gases.
