DEFINITION

Classification: 95/58

With addition of solid, gas, or vapor:

(under subclass 57) Process which includes adding a solid, gas, or vapor to the fluid mixture undergoing treatment or separation.

(1) Note. To come under this definition, the added solid, gas, or vapor must not be merely a different amount of the same fluid mixture that is to be separated, but may be a constituent of this mixture, which may be derived from a previous separation process.

(2) Note. The addition of solid includes the use of a fluidized solid particle bed, regardless of whether the solid remains entrained in the gas after passage through the bed. The use of a stationary particle bed is not considered to be addition of a solid, and patents in which a stationary particle bed is used will be found elsewhere under subclass 57. Also, for the purposes of this subclass, the added solid, gas, or vapor may include any combination thereof (except for a different amount of the fluid mixture to be separated, as in (1) Note), including aerosols.
