Classification: 585/655

With plural separation procedures applied to effluent or effluent component:

(under subclass 654) Subject matter wherein the effluent from the dehydrogenation reaction or a component thereof passes through at least two separation steps.

(1) Note. A mere nominal "recovery" or "separating" step is not sufficient to warrant placement of a patent herein.

(2) Note. Many patents contained herein seek to recover a separate hydrocarbon in addition to the main dehydrogenation product.
