WebSep 23, 2014 · Rayleigh distillation is an important concept in geochemistry – applied to isotopic and elemental systems ranging from crystallization in magma chambers to oxygen isotope stratigraphy across glacial-interglacial periods. A teaching module that allows students to discover first-hand consequences of isotopic fractionation and Rayleigh ... WebBatch distillation is a transient process in which the compositions in the still and the distillate change with time. The Rayleigh equation relates the amount remaining in the still to mole fractions of the more-volatile component (MVC) in the still and the distillate.
