Class Information
Number: 55/401
Name: Gas separation > Mounted or supported for continuous motion > Plural distinct separating media or stages
Description: Apparatus comprising two or more separating means, at least one of which is continuously moving, each functioning substantially independently of the other (1) as a separating means for only a portion of the system fluid or (2) as one of a series of separation phases wherein each downstream separating means treats the effluent of the preceding upstream means.
