DEFINITION

Classification: 585/718

With coalescing or sorption of, or addition of specific agent to, effluent or effluent component:

(under subclass 709) Subject matter wherein the effluent from the alkylation reaction or a component thereof is treated, employing a chemical or physical phenomenon, to purify or separate the effluent or effluent component, the phenomenon being coalescence or sorption of with a solid sorbent, or requiring the addition of a material from outside the reaction mixture, e.g., a solvent, a reactant, a reaction inhibitor, etc.

(1) Note. See the notes to subclass 719 for a summary of other subclasses dealing with after treatments of alkylation effluent.
