A system and method for loading material from a converter bed, such as that in a converter of an acid plant, is provided. The system, may include a vacuum source; a dust collector connected to the vacuum source by a first vacuum hose; a cyclone operatively connected to the vacuum source through the dust collector, wherein the cyclone may be connected to the dust collector by a second vacuum hose; a drop-out hopper operatively attached to the cyclone by a valve, such as an air actuated valve, wherein the drop-out hopper includes a first feed hose; and one or more material storage containers operatively associated with the cyclone via a second feed hose. The method of loading material into a converter bed may include providing a system for loading the material in the converter bed; setting up the system; and loading the material into the converter bed.

The separation according to the invention of a material-laden hot gas stream substantially consists of the following method steps: the material-laden hot gas stream is separated in a first separator into a gas stream and a material stream, wherein the material stream contains a coarser and a finer fraction, and the material stream is then classified in a classifier with at least a proportion of the gas stream, the coarser fraction of the material stream being discharged, while the finer fraction is carried away together with the gas stream separately from the coarser fraction.

Apparatus and methods for size-specific detection of particles entrained in fluids are provided. A particle size selector separates particles entrained in a sample fluid stream using a curved channel. Shroud fluid streams are interposed between the sample fluid stream and walls of the channel. Centrifugal forces arising from fluid flow through the curved channel separate differently-sized particles into different transverse sections of the channel. A detector downstream from the particle size selector specifically detects particles in one or more transverse sections of the channel.
