5.0 HOPPER DESIGN
5.1 Bulk solid handling
Measuring the flow properties of bulk
solids and how to use this information for
the design of storage vessel.
Bin: Any upright container for storing bulk
Silo: A tall bin, where H > 1.5D
Colloids and Fine Particles (Introduction) Example : Removal colloidal particle
from raw water
Solids are present in water in three main forms:
suspended particles, colloids and dissolved molecules.
Suspended particles, such as sand, vegetable matter
6.0 PNEUMATIC TRANSPORT
For many years, gases have been used in
industry to transport particulate solids.
Dense phase pneumatic transport vs. dilute
o Solids are not fully suspended.
o Low air requirement.
o Lower energy requi
FLUIDIZATION AND ENTRAINMENT
has been a key technology in Fluid Catalytic Cracking
(FCC) to make gasoline in petroleum industry
in catalytic processes such as partial oxidation of
ammonia to acrylonitrile to prepare acrylic resi
