Describe the process of fluidization and its applications in chemical engineering.
a) Fluidization involves the conversion of a solid material into a fluid-like state by passing gas or liquid through it, used in processes like catalysis and drying.
b) Fluidization is the separation of fluids from solids, commonly used in wastewater treatment.
c) Fluidization refers to the process of converting gases into liquids, important in cryogenic applications.
d) Fluidization has no applications in chemical engineering.
