Class Information
Number: 96
Name: Gas separation: apparatus >
Description: This class provides for apparatus used in separation of a gas from a fluid mixture comprising (i) a gas and solid or liquid particles entrained therein, (ii) a liquid and gas entrained therein, or (iii) a plurality of gases. As a general rule for this class, there must be a relationship of apparatus parts embracing: (a) an inlet for the fluid mixture to be treated, (b) a means effective to cause separation into constituent parts, and (c) an outlet for at least one constituent separate and distinct from an outlet for another constituent, which may be for removal of the separating media itself, or a single outlet used at different times to remove the separated constituents. The gas separation apparatus for this class does not include means in which the separation is caused by a chemical reaction.
