ABSTRACT OF THE DISCLOSURE A dust control apparatus in the form of a hood is disclosed for minimizing or eliminating the evolution of dust when loading dust laden solid discrete particles from a large container to a series of small containers. The appara- tus is designed specifically for unloading spent catalysts from catalytic vessels into a series of drums without evolu- tion of voluminous clouds of dust. The apparatus and method are designed to be portable so that expensive and sophisti- cated installations are not required in instances where the vessels are infrequently unloaded. The dust control hood makes use of the angle of repose of the solid discrete par- ticles to be transferred in such manner that the drums do not overfill. Simultaneously, air is drawn across the hood and the dust is collected in a suitable filter at a distance away from the loading area. Provision is also made for separa- tion and collection of dust from pyrophoric materials utilizing an inert gas rather than air as the carrier medium.
