Theoretical plate 뜻
WebbTheoretical plate number (N) is an index that indicates column efficiency. It describes the number of plates as defined according to plate theory, and can be used to determine column efficiency based on calculation in … WebbSimple distillation systems have, by definition, one theoretical plate at best, possibly even less when not run optimally. Similarly, this also applies to physical plate/tray columns – e.g. one practical plate typically has 90% or so of the …
